The complete anatomy of the iliolumbar artery: a meta-analysis with clinical implications. Folia Morphol (Warsz) 2024:VM/OJS/J/99720. [PMID: 38757495 DOI: 10.5603/fm.99720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Accepted: 04/22/2024] [Indexed: 05/18/2024]
Abstract
BACKGROUND The arterial anatomy of the pelvic region is highly variable, and variations in the anatomy of the ILA may often be observed in its point of origin. The main objective of the present meta-analysis was to provide the most up-to-date and evidence-based data regarding the complete anatomy of the iliolumbar artery (ILA. It is hoped that our results may aid in reducing possible complications associated with various procedures performed in the pelvis. MATERIALS AND METHODS To perform this meta-analysis, major online medical databases - PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar - were searched through to find all studies considering the anatomy of the ILA. RESULTS The pooled prevalence of the ILA originating from the Internal Iliac Artery, in the overall analysis, was found to be 93.62% (95% CI: 82.96-99.63%). Mean diameter of the ILA was found to be 2.67 mm (Standard Error = 0.19 ; Lower Limit = 2.29 ; Upper Limit = 3.05). Mean length of the ILA was established at 12.50 mm (Standard Error = 1.64 ; Lower Limit = 9.28 ; Upper limit = 15.73). CONCLUSIONS The anatomy of the ILA was found to be quite constant, in contrast to what has been discussed in the literature. The said artery originated most frequently from the internal iliac artery (93.62%). Most frequently, this artery originated from the internal iliac artery (observed in approximately 93.62% of cases). Notably, the results of our current meta-analysis indicate that the average distance between the ILA's point of origin, the lower margin of the L5 vertebra, and the bifurcation site of the common iliac artery were 43.20 mm and 28.58 mm, respectively.

Enhancing Buttock Contours: A Safer Approach to Gluteal Augmentation with Ultrasonic Liposuction, Submuscular Implants, and Ultrasound-Guided Fat Grafting. J Clin Med 2024; 13:2856. [PMID: 38792398 PMCID: PMC11122434 DOI: 10.3390/jcm13102856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 04/23/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024] Open
Abstract
Background: The global popularity of gluteal augmentation has risen significantly, driven by the desire for enhanced buttocks size and shape to align with individual patient preferences. This increased demand has prompted extensive research into diverse techniques and their safety. Methods: A retrospective analysis was conducted to evaluate the outcomes of a gluteal augmentation technique involving ultrasound-assisted liposuction, submuscular implants, and ultrasound-guided fat grafting. Our study involved a review of the medical records of 50 consecutive patients who underwent this procedure between February 2020 and July 2023. Results: Data related to patient demographics, the quantity of fat grafts, and any complications were analyzed. Additionally, a brief survey was conducted to evaluate patient satisfaction. The Polytech implants were used in forty-four patients, and Sebbin implants in six. The implant size varied from 285 to 560. Most of the Polytech implants were 390 cc (25/44; 56.8%). Two patients had a minor infection at the incision sites and subsequent wound dehiscence. No revision surgeries were needed. Conclusions: The presented technique incorporates ultrasonic liposuction, submuscular silicone implants, and ultrasound-guided fat grafting to achieve safe and aesthetic gluteal enhancements. This method is especially suitable for patients looking to augment both the central and lateral areas of the buttocks, particularly when they lack adequate fat tissue for augmentation through fat grafting. With the addition of ultrasound guidance, the fat grafting step is significantly safer.

Scapular foramina - a systematic review with meta-analysis based on 3316 scapulae. Surg Radiol Anat 2024:10.1007/s00276-024-03363-4. [PMID: 38652255 DOI: 10.1007/s00276-024-03363-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Accepted: 03/31/2024] [Indexed: 04/25/2024]
Abstract
PURPOSE In the present study, we want to systematize the previous studies on the scapular foramina (SF) and nutrient foramina (NF) with emphasis on the clinical relevance of this topic. Although seemingly not important, radiologists, clinicians and surgeons should be aware of the presence and characteristics of the SF and NF and look out for possible mistakes that may cause harm to the patients during either the diagnostic process or surgery. METHODS A comprehensive search was conducted in multiple databases, including PubMed, Scopus, Web of Science, Embase, Cochrane Library and Google Scholar. The whole process was divided into three stages. In the first stage, the following search terms were used: ((scapular foramina) or (scapular foramen) or (scapular nutrient foramina) or (scapular nutrient foramen) or (scapula foramen) or (scapula foramina) or (scapula nutrient foramina)). RESULTS The results of the present meta-analysis were based on a total of 3316 studied scapulae. A pooled prevalence of scapulae in which at least one SF was found was set to be 11.29%. The most common localization of the SF was found to be the infraspinous fossa, in which the SF occurred with the prevalence of 52.31%. Subsequently, a pooled prevalence of scapulae in which at least one NF occurs was established at 74.23%. CONCLUSION The presented data contribute to a comprehensive understanding of the prevalence, distribution, and characteristics of suprascapular and nutrient foramina in scapulae, considering different topographical areas, genders, and sides.

Exploring the Topography of the Obturator Artery and Corona Mortis: a Detailed Analysis with Surgical Implications. Int Urogynecol J 2024:10.1007/s00192-024-05774-8. [PMID: 38635039 DOI: 10.1007/s00192-024-05774-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 03/06/2024] [Indexed: 04/19/2024]
Abstract
INTRODUCTION AND HYPOTHESIS The obturator artery (ObA) is described as a branch of the anterior division of the internal iliac artery. It arises close to the origin of the umbilical artery, where it is crossed by the ureter. The main goal of the present study was to create an anatomical map of the ObA demonstrating the most frequent locations of the vessel's origin and course. METHODS In May 2022, an evaluation of the findings from 75 consecutive patients who underwent computed tomography angiography studies of the abdomen and pelvis was performed. RESULTS The presented results are based on a total of 138 arteries. Mostly, ObA originated from the anterior trunk of the internal iliac artery (79 out of 138; 57.2%). The median ObA diameter at its origin was found to be 3.34 mm (lower quartile [LQ] = 3.00; upper quartile [UQ] = 3.87). The median cross-sectional area of the ObA at its origin was found to be 6.31 mm2 (LQ = 5.43; UQ = 7.32). CONCLUSIONS Our study developed a unique arterial anatomical map of the ObA, showcasing its origin and course. Moreover, we have provided more data for straightforward intraoperative identification of the corona mortis through simple anatomical landmarks, including the pubic symphysis. Interestingly, a statistically significant difference (p < 0.05) between the morphometric properties of the aberrant ObAs and the "normal" ObAs originating from the internal iliac artery was found. It is hoped that our study may aid in reducing the risk of serious hemorrhagic complications during various surgical procedures in the pelvic region.

Biomechanical evaluation of the wrist after scaphotrapeziotrapezoid arthrodesis. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024:10.1007/s00590-024-03931-9. [PMID: 38594457 DOI: 10.1007/s00590-024-03931-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Accepted: 03/20/2024] [Indexed: 04/11/2024]
Abstract
BACKGROUND The main objective of the present study was to present the biomechanical properties of the wrist in patients who underwent scaphotrapeziotrapezoid arthrodesis when compared to a healthy control hand. METHODS The study group consisted of 29 consecutive patients who underwent a scaphotrapeziotrapezoid wrist arthrodesis at least 1 year before the research onset. Both hands of all patients were examined in 4 main categories. RESULTS Average score obtained in the VAS, before the surgery, without motion of the wrist was 5.21 (SD = 3.04), whereas with wrist motion, it was 8.10 (SD = 1.37). Nineteen (65.52%) patients exhibited weakened wrist muscle strength. After the surgery, only 5 (17.24%) patients declared pain in the wrist. Furthermore, the results obtained in the VAS statistically significant differed from the ones before (p < 0.05). Twenty-eight (96.55%) patients were able to resume their profession. Twenty-seven (93.10%) patients stated that they would opt for the operation again. The peak torque during the analysis of extension of the wrist in the isometric protocol was found to be 8.1 Nm (SD = 2.9), 7.9 Nm (SD = 2.3), and 7.9 Nm (SD = 2.5) in the operated hands and 10.9 Nm (SD = 3.2), 9.6 Nm (SD = 2.9), and 9.1 Nm (SD = 3.8) in non-operated hand for 30° extension, no-flexion, and 30° flexion positions, respectively (p < 0.05). CONCLUSION The current study is the first to present the biomechanical parameters of flexor and extensor muscles of the wrist and fingers in patients after the said procedure. Biomechanical assessments with additional isometric, isotonic, and isokinetic tests provide an opportunity to objectify treatment outcomes and guide appropriate rehabilitation by monitoring its effects.

Association between serum TSH concentration and bone mineral density: an umbrella review. Hormones (Athens) 2024:10.1007/s42000-024-00555-w. [PMID: 38581565 DOI: 10.1007/s42000-024-00555-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 03/26/2024] [Indexed: 04/08/2024]
Abstract
INTRODUCTION The aim of this study was to summarize the results of previous studies, standardize the data, and present new statistical results in order to provide physicians with clinically significant outcomes regarding the association between serum TSH concentration and bone mineral density (BMD). METHODS To perform this umbrella review, a systematic search was conducted in which major online medical databases, such as PubMed, Web of Science, Embase, Scopus, Cochrane Library, and Google Scholar, were searched for meta-analyses and systematic reviews regarding the effect of TSH on BMD. Furthermore, all primary studies were screened for statistical analysis. RESULTS The statistical outcomes of the present study were based on the data of 75,898 patients. The pooled risk ratio of any kind of fracture in patients with subclinical hyperthyroidism was estimated to be 1.36 (95% CI: 1.18-1.56; p < 0.001). The SMD for BMD in the distal radius in male patients receiving L-thyroxine suppression therapy was estimated to be -0.61 (95% CI: -1.10-(-0.11); p = 0.02). Furthermore, the pooled risk ratio of any fracture in patients receiving L-thyroxine suppression therapy was estimated to be 1.98 (95% CI: 0.98 - 3.98; p = 0.06). In these patients, the BMD may significantly differ from that in non-treated patients. However, the difference depends on the type of bone. CONCLUSIONS Our data confirmed that subclinical hyperthyroidism has a detrimental effect on bones, causing decreased BMD. Based on the obtained results, the authors suggest that a reduced TSH serum level itself may be an individual factor associated with decreased BMD and, thus, with a greater risk of bone fracture. Nevertheless, it should be noted that the effects of TSH suppression therapy differ between areas of interest for assessing BMD. Furthermore, the results have shown that this issue may, in specific areas, concern not only postmenopausal women but also male patients. These conclusions should contribute to a careful consideration of the application of TSH suppressive therapy in all patients. Particular attention should be given to patients after DTC, while all the advantages and disadvantages of implementing L-thyroxine therapy should be individually considered.

Exploring the clinical characteristics and prevalence of the annular pancreas: a meta-analysis. HPB (Oxford) 2024; 26:486-502. [PMID: 38310080 DOI: 10.1016/j.hpb.2024.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 12/17/2023] [Accepted: 01/15/2024] [Indexed: 02/05/2024]
Abstract
BACKGROUND The annular pancreas (AP) is a rare gastrointestinal congenital malformation, in which malrotation of the pancreatic ventral bud in the seventh week of embryonic development manifests in a partial or complete ring of tissue around the second part of the duodenum. METHODS The main online medical databases such as PubMed, ScienceDirect, Wiley online library, Web of Science, and EBSCO discovery service were used to gather all relevant studies on the AP. RESULTS A total of 12,729,118 patients were analyzed in relation to the prevalence of AP. The pooled prevalence of AP was 0.0045% (95% CI: 0.0021%-0.0077%). The most frequent comorbidity in adults and children was duodenal obstruction, with a pooled prevalence of 24.04% and 52.58%, respectively (95% CI: 6.86%-46.48% and 35.56%-69.31%, respectively). The most frequent operation in adult patients with AP was duodenojejunostomy, with pooled prevalence established at 3.62% (95% CI: 0.00%-10.74%). CONCLUSION The diagnostic complexity of AP is accentuated by its nonspecific clinical symptoms, making accurate identification reliant on imaging studies. Therefore, having a thorough knowledge of the clinical characteristics of the AP and its associated anomalies becomes paramount when faced with this rare congenital condition.

Assessing complications and functional outcomes in proximal humerus fracture management: a retrospective comparison between conservative and intramedullary nailing treatments. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:1427-1433. [PMID: 38233566 DOI: 10.1007/s00590-023-03822-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 12/21/2023] [Indexed: 01/19/2024]
Abstract
INTRODUCTION Fractures of the proximal end of the humerus (FPH) are the second most common fractures in the upper limb after fractures of the distal radius and are two to three times as common in women than in men. Therefore, the main objective of the present study was to compare and analyze the complications and the functional outcomes in patients with displaced FPH receiving conservative and surgical treatments with intramedullary nailing. METHODS A retrospective cross-sectional study was conducted to establish the differences in complications risks between surgical and non-surgical treatment of the FPH. For this purpose, the clinical and radiological results of 67 consecutive patients were analyzed. RESULTS A total of 25 patients were included in the non-surgically treated group. A total of 42 patients were included in the surgically treated group. Complications occurred in a total of 4 (16.0%) patients after the non-surgical treatment. Those included frozen shoulder (n = 2), nonunion (n = 1), and avascular necrosis of the humeral head (n = 1). Complications occurred in a total of 18 (42.6%) patients after the surgical treatment. Non-surgically treated patients had statistically significantly (p < 0.05) lower scores in the Constant-Murley scale in all of the categories. CONCLUSION The present study demonstrates an overall prevalence of complications to be 16% in patients treated conservatively and 42.6% in patients treated surgically. In the non-surgical cohort, the frozen shoulder was the most frequently observed complication (8%). Interestingly, non-anatomical repositioning was the most prevalent complication in surgically treated patients. Due to the complexity of the FPH, we believe that the surgeon needs to have comprehensive knowledge regarding the characteristics of this fracture, the available treatment options, and the possible complications that may occur. This can enhance patient safety and provide satisfactory clinical outcomes.

The anatomy of the internal iliac artery: a meta-analysis. Folia Morphol (Warsz) 2024:VM/OJS/J/97800. [PMID: 38512006 DOI: 10.5603/fm.97800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 03/06/2024] [Accepted: 03/07/2024] [Indexed: 03/22/2024]
Abstract
BACKGROUND The internal iliac artery (IIA) originates from the common iliac artery at the level of the sacroiliac joint and bifurcates between the L5 and S1 vertebrae. The aim of the present meta-analysis was to demonstrate the most up-to-date and evidence-based data regarding the general anatomy of the IIA, including their variations, length, and diameter. MATERIALS AND METHODS Major online medical databases such as PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar were searched in order to find all studies considering the anatomy of the IIA. Eligibility assessment and data extraction stages were performed. RESULTS In the general population the pooled prevalence of Type I (The superior gluteal artery arises independently with the inferior gluteal and internal pudendal arteries arising from a common trunk which dividing inside (Type IA) or outside (Type IB) pelvic cavity) was found to be 56.57% (95% CI: 53.00-60.10%). The pooled mean length of the IIA was set to be 39.95 mm (SE = 1.79) in the overall population. The pooled mean diameter of the IIA was found to be 6.86 mm (SE = 0.27). CONCLUSIONS The IIA is responsible for supplying the majority of the structures located in the pelvis. Hence, it is crucial to be aware of the possible variants of the said vessel. The results presented in our study may be highly significant in various surgical procedures performed in that region.

Abstract
BACKGROUND The transverse facial artery (TFA) provides blood supply to various structures of the lateral face, including the parotid gland, parotid duct, masseter muscle, and facial skin. Knowledge about its anatomy is of utmost importance in various plastic and reconstructive procedures. MATERIALS AND METHODS The results of 55 (110 hemifaces) consecutive patients who underwent head and neck computed tomography angiography (CTA) in the Department of Radiology of the Jagiellonian University Medical College, Cracow, Poland, were evaluated in July 2022. RESULTS TFA was found to originate from STA in 84 of the cases (95.5%), whereas from ECA only in 4 of the cases (4.5%). Median length of the TFA was found to be 43.39 mm (LQ = 38.53 ; UQ = 46.37). The median TFA diameter, at its origin, was established at 2.26 mm (LQ = 1.93 ; UQ = 2.54). Median TFA cross-sectional area, at its origin, was set to be 2.54 mm (LQ = 1.67 ; UQ = 3.10). CONCLUSIONS The TFA has an important role in the arterial blood supply to the face, and the present study has demonstrated its stable prevalence in the lateral face region. The most frequent origin of the artery was from the STA; however, it also originated from the ECA in some cases. Moreover, the topographic relationships between the TFA and nearby arteries and anatomical landmarks were measured and analyzed.

Abstract
BACKGROUND The objective of this meta-analysis was to investigate the anatomical variations of the mandibular lingula (ML) and its relationship to surrounding anatomical structures. Understanding such variations is crucial to help determine the site and depth of a successful inferior alveolar nerve (IAN) anesthetic block as well as a safe area for oral and maxillofacial invasive procedures in order to minimize the risk of neurological or hematological damage to the inferior alveolar nerve. MATERIALS AND METHODS A systematic search was conducted in which all studies were searched on the anatomy of ML. Major medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library were searched. RESULTS All of the results were based on a total of 4694 subjects. The overall height of the ML was found to be 8.17 mm (SE =0.22). The Triangular Type of the ML was found to be the most common one. The pooled prevalence of this variation was found to be 29.33% (LCI = 23.57% ; HCI = 35.24%). The pooled prevalence of the Nodular Type was set to be 27.99% (LCI = 22.64% ; HCI = 33.67%). CONCLUSIONS The present meta-analysis provides clinically relevant information regarding the shape, location, and height variations of the ML. Understanding such variations of the ML is crucial when performing malocclusion corrections procedures that require the ML as a landmark, namely sagittal split ramus osteotomy, and intraoral vertical ramus osteotomy. Furthermore, effective anesthetic blocks during oral and maxillofacial procedures can be accomplished with a higher success rate if the correct site of injection is identified. The possible locations of the ML should be considered in order to determine the location of the mandibular foramen and, therefore, inferior alveolar bundle in order to prevent motor, sensory, or perfusion pathology during maxillofacial and oral procedures of the lower jaw.

Abstract
BACKGROUND The superior gluteal artery (SGA) is the largest, terminating branch of the internal iliac artery (IIA). Knowledge about the anatomy of the SGA is extremely important when performing numerous reconstructive and endovascular procedures. MATERIALS AND METHODS The results of 75 consecutive patients who underwent pelvic computed tomography angiography (CTA) were analyzed. RESULTS A total of 145 SGA were analyzed. The origin variation of each SGA was deeply analyzed. Type O1 occurred in 79 SGA (56.4%). Furthermore, analogously, a branching pattern types were also established. Initially 19 branching variations were evaluated, of which types 1-7 constituted 76.5%. The median SGA length was set to be 54.88 mm (LQ = 49.63 ; HQ = 63.26). The median SGA origin diameter, in cases of SGA originating from PDIIA was set to be 6.27 mm (LQ = 5.56 ; HQ = 6.87). CONCLUSIONS The origin of the said artery showed a low grade of variability, and the most prevalent origin type of the SGA was similar to the one presented by the major anatomical textbooks, namely, the PDIIA. However, the branching pattern of the SGA was highly variable. To present the anatomy of the SGA in a clear and straight-forward way, novel classification systems of the origin and branching patterns were made. Furthermore, the morphometric properties of the branches of the PDIIA were analyzed. It is hoped that the results of the present study may be useful for physicians performing numerous reconstructive and endovascular procedures.

Abstract
BACKGROUND The anatomy of the posterior auricular artery (PAA) is highly variable and relevant in various plastic and reconstructive procedures. MATERIALS AND METHODS The results of 55 consecutive patients who underwent head and neck computed tomography angiography (CTA) were analyzed. A total of 78 hemifaces were evaluated. The analysis has been performed in 19 categories. RESULTS Median PAA length was found to be 47.59 mm (LQ = 32.75; HQ = 56.16). The median PAA diameter (at its origin) was established at 2.55 mm (LQ = 2.29; HQ = 2.90). Moreover, the median PAA cross-sectional area (at its origin) was set to be 3.22 mm (LQ = 2.49; HQ = 4.13). Sexual dimorphism regarding all of the measured parameters was also evaluated. Statistically significant differences (p ≤ 0.05) were found in 13 of the measured categories. CONCLUSIONS The present study demonstrated the complete anatomy of the PAA. The most frequent origin of the said artery was from the ECA, and its mean length was 45.07 mm; which did not differ between males and females significantly (p>0.05). Moreover, we have provided surgeons with tools to localize this artery pre- and intraoperatively using simple landmarks, namely the apex of the mastoid process and the center of the external acoustic meatus. The exact position of the origin of the PAA was also demonstrated by a heat map of the auricular region. Our findings have the potential to assist surgeons in developing a mental visualization of the arterial anatomy of the retroauricular region. This visualization can be instrumental in precisely identifying the location of the PAA during reconstructive surgeries, thereby minimizing complications and enhancing surgical outcomes.

Abstract
The main objective of the present study was to clarify the anatomical characteristics of the GDA. In order to fulfill this objective, novel classification systems of both the origin and branching pattern of the said vessel were created. Being aware of the variable anatomy of the GDA is of great importance when performing hepatopancreaticobilliary procedures. The results of 75 consecutive patients who underwent abdomen computed tomography angiography (CTA) were analyzed. A total of 74 GDA were analyzed. Of these, 42 were from women (56.8%) and 32 were from men (43.2%). The most common direction of origin of the GDA was inferior (n = 38; 51.4%). The origin variation of each GDA was deeply analyzed. Initially, eight types of origin variations were evaluated, of which types 1-3 constituted 83.8%. Furthermore, analogously, branching pattern types were also established. Initially, 11 branching variations were evaluated, of which types 1-3 constituted 87.8%. The GDA is subject to numerous variations, both in the origin and in the branching pattern of the vessel. In order to clarify the anatomical characteristics of this vessel, novel classifications of the origin and branching patterns were made, presenting the most frequent patterns. Our results may be of great use for surgeons performing hepatopancreaticobilliary surgeries, such as the Whipple procedure or vascular reconstructions after cholangiocarcinoma resections. Being aware of the anatomical variations of relevant structures associated with a surgical procedure may help reduce potential intraoperative and/or postoperative complications.

Treatment Options for Tennis Elbow - An Umbrella Review. FOLIA MEDICA CRACOVIENSIA 2023; 63:31-58. [PMID: 38310528 DOI: 10.24425/fmc.2023.147213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 02/06/2024]
Abstract
INTRODUCTION The main goal of the present umbrella review was to provide the most up-to- date and evidence-based results regarding the various treatment options for tennis elbow (TE), which hopefully will significantly decrease the confusions existing in the literature. Furthermore, our study differs from past analytical studies because, as to the best of the authors' knowledge, is the first to provide independent (not in comparison to other treatment) statistical results regarding the effectiveness of each TE treatment. MATERIALS AND METHODS Major medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library, BIOSIS, and EBSCO were searched. The overall search process was conducted in 3 stages. RESULTS A total of 40 studies met the inclusion criteria and were included in this study. Out of those 40 meta-analyses, a total of 160 primary studies were screened in order to extract the data and perform a statistical analysis. CONCLUSION The present umbrella review underlines the efficiency of injection therapies, especially autologous blood, and platelet-rich plasma, while simultaneously proving the ineffectiveness of acupuncture and shock wave therapy as treatments for TE. Furthermore, the value of other known conservative treatment modalities, such as physical therapy, has been demonstrated.

Abstract
Our objective was to analyse the newest relevant data on worldwide prevalence and associated symptoms of renal agenesis (RA). This meta-analysis builds on previous systematic reviews to include bilateral RA, its symptoms and data on gender, unilateral RA and anomaly location prevalence. Review of available data included records in English and other languages from PubMed, Embase, ScienceDirect, Web of Science, SciELO, BIOSIS, Current Content Connect Korean Journal Database and Russian Citation Index and Google. A total of 15 641 184 patients were analysed in relation to the prevalence of RA. The pooled prevalence of RA was 0.03% (95% CI: 0.03%-0.04%). Based on 500 subjects, a pooled prevalence of 47.96% (95% CI: 31.55%-64.58%) for unilateral and 52.04% (95% CI: 35.42%-68.45%) for bilateral RA has been set. Our study presents the newest generalized findings on bilateral RA. There appears to be universal disease and symptom prevalence with minor differences between world regions, although quality of future observational research should include genomic data. This will provide even further insight into the prognosis of various renal anomalies and their etiologies.

Abstract
Skeletal muscle tissue (SKM) may be damaged due to mechanical, metabolic, and exertional causes. However, drug-induced myopathy is among the most frequent causes of muscle disease. The clinical picture of drug-induced myopathies may be highly variable. It may present as asymptomatic or mild myalgias, with or without muscle weakness, which are likely underreported. However, it may also appear as chronic myopathy with severe weakness and, rarely, even as massive rhabdomyolysis with acute kidney injury (AKI). Unfortunately, the available biomarkers for SKM injury do not fully meet the needs for satisfactory detection of drug-induced damage, both in clinical and research settings, mainly due to their low sensitivity and specificity. Therefore, the present study proposes a strategy for drug safety monitoring using the available biomarkers of SKM injury. Moreover, we will discuss mechanisms of drug-induced SKM injury, traditional laboratory testing for SKM injury, and novel skeletal myocyte biomarkers under investigation. This can be incredibly useful in both clinical practice and for de-challenge/re-challenge investigational trials where the risk of drug-induced SKM injury is present.

Abstract
Lingual nerve (LN) injury during surgical procedures in the third molar region warrants a detailed study of its common pathway and important variations. Therefore, the objective of this study was to analyze and compile the multiple anatomical variations of the LN for use in oral and maxillofacial surgery. It is anticipated that the results of the present meta-analysis may help to minimize the possible complications when performing procedures associated with this anatomical entity. Major online databases such as PubMed, Web of Science, Scopus, Embase were used to gather all relevant studies regarding the LN anatomy. The results were established based on a total of 1665 LNs. The pooled prevalence of the LN being located below the lingual/ alveolar crest was found to be 77.87% (95% CI: 0.00%-100.00%). The LN was located above the lingual/ alveolar crest in 8.21% (95% CI: 4.63%-12.89%) of examined nerves. The most common shape of the LN was established to be round with a prevalence of 40.96% (95% CI: 23.96%-59.06%), followed by oval at 37.98% (95% CI: 23.98%-53.02%) and flat at 25.16% (95% CI: 12.85%-39.77%). In conclusion, we believe that this is the most accurate and up-to-date study regarding the anatomy of the LN. The LN was found to be located below the lingual/alveolar crest in 77.87% of the cases. Furthermore, the LN was found to enter the tongue under the submandibular duct in 68.39% of the cases. Knowledge about the anatomy of the LN is crucial for numerous oral and maxillofacial procedures such as during the extraction of the third molar.

Abstract
The pyramidal lobe (PL), also known as the third lobe of the thyroid gland or lobe of Lalouette is an embryological remnant of the caudal end of the thyroglossal tract. The following meta-analysis aims to provide a detailed analysis of the anatomical variations of the PL using the available data in the literature. Major online medical databases such as PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar were searched in order to find all studies considering the prevalence and anatomy of the PL of the thyroid gland. Finally, a total of 24 studies that met the required criteria and contained complete and relevant data were included in the present meta-analysis. The pooled prevalence of the PL was found to be 42.82% (95% CI: 35.90%-49.89%). An analysis showed that the mean length was 23.09 mm (SE: 0.56). The mean width was found to be 10.59 mm (SE: 0.77). The pooled prevalence of the PL originating from the left lobe (LL) was established at 40.10% (95% CI: 28.83%-51.92%). In conclusion, we believe that this is the most accurate and up-to-date study regarding the complete surgical anatomy of the PL. The PL was prevalent in 42.82% of the cases, being slightly more prevalent in males (40.35%) than females (37.43%). The mean length and width of the PL were 23.09 mm and 10.59 mm, respectively. Our results should be taken into consideration when performing procedures on the thyroid gland, such as thyroidectomies. The presence of the PL can affect the completeness of this procedure and lead to postoperative complications.

Abstract
The objective of the present meta-analysis was to evaluate recent and applicable data regarding the location and variation of the atrioventricular nodal artery (AVNA) in relation to adjacent structures. In order to minimize postoperative risks and maintain physiological anastomosis for proper cardiac function, understanding such possible variations of vascularization of the AV node is of immense importance prior to cardiothoracic surgery as well as ablations. In order to perform this meta-analysis, a systematic search was conducted in which all articles regarding, or at least mentioning, the anatomy of the AVNA was searched. In general, the results were based on 3919 patients. AVNA was found to originate only from the RCA in 82.41% (95% CI: 79.46%-85.18%). The pooled prevalence of AVNA originating only from LCA was found to be 15.25% (95% CI: 12.71%-17.97%). The mean length of AVNA was found to be 22.64 mm (SE = 1.60). The mean maximal diameter of AVNA at its origin was found to be 1.40 mm (SE = 0.14). In conclusion, we believe that this is the most accurate and up-to-date study regarding the highly variable anatomy of the AVNA. The AVNA was found to originate most commonly from the RCA (82.41%). Furthermore, the AVNA was found to most commonly have no (52.46%) or only one branch (33.74%). It is hoped that the results of the present meta-analysis will be helpful for physicians performing cardiothoracic or ablation procedures.

Abstract
BACKGROUND This meta-analysis aimed to present data on the sella turcica (ST) morphology and variations. Furthermore, a detailed morphometric analysis of the ST was conducted. METHODS Major online databases such as PubMed, Scopus, Embase, Web of Science, and the Cochrane Library were searched through. The overall search process was conducted in three stages. RESULTS This meta-analysis was based on the results of 18,364 patients and demonstrates the most up-to-date and relevant data regarding the morphology of the ST in the available literature. Four classification methods of the ST shape can be distinguished, in which the most commonly occurring variants are the normal ST (55.56%), the U-shaped ST (73.58%), the circular type of ST (42.29%), and non-bridging ST (55.64%). The overall midpoint height of the ST was 6.59 mm (SE = 0.13). The overall length of the ST was 9.06 mm (SE = 0.15). The overall volume of the ST was 845.80 mm3 (SE = 288.92). Four main classification methods of ST morphology can be distinguished in the available literature. Various morphometric characteristics of the ST may be applied in clinical practice to evaluate its shape, dimensions, and normal or pathological variants.

Abstract
Knowledge about the anatomy of the submental artery (SA) is of immense importance when performing plastic and reconstructive procedures. A retrospective study was performed to analyze the topographic anatomy of the SA. The measurements were performed on 80 consecutive patients who underwent head and neck computed tomography angiography (CTA). The SA was present in 131 out of 137 hemifaces (95.6%). The vessel originated from the facial artery in all cases (100.0%). Moreover, the SA was found to have 0-4 branches. However, most commonly, the said artery had no branches of considerable size (51.1%). Due to the high variability of the course of the said artery, the authors of the present study created a novel classification system presenting the most prevalent courses of the SA in the submental region. The current study utilized 131 hemifaces of 80 (CTA) to create a heat map of the SA, illustrating its precise origin and course in the submental region. The findings of this study could assist surgeons in developing a mental map of the arterial anatomy of the submental region, potentially improving the efficiency of localizing the SA and reducing the risk of complications during plastic and reconstructive procedures.

Evaluation of lateral epicondylopathy, posterior interosseous nerve compression, and plica syndrome as co-existing causes of chronic tennis elbow. INTERNATIONAL ORTHOPAEDICS 2023; 47:1787-1795. [PMID: 37071147 PMCID: PMC10267267 DOI: 10.1007/s00264-023-05805-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 03/30/2023] [Indexed: 04/19/2023]
Abstract
PURPOSE A great number of patients that suffer from lateral epicondylitis, commonly called tennis elbow (TE), are not successfully treated, meaning, not getting adequate therapeutic effects and the main origin of the pain not being handled appropriately. The hypothesis of the present study is that the inefficiency of the treatment of the chronic TE may often be due to underdiagnosis of posterior interosseous nerve (PIN) entrapment or and plica syndrome, as the authors believe that those pathologies can often occur simultaneously. METHODS A prospective cross sectional study was conducted. A total of 31 patients met the required criteria. RESULTS Thirteen (40.7%) of the patients had more than one source of the lateral elbow pain. Five patients (15.6%) had all three examined pathologies. Six patients (18.8%) had TE and PIN syndrome. Two patients (6.3%) had TE and plica syndrome. CONCLUSION The present study demonstrated concomitant potential sources of lateral elbow pain in patients diagnosed with chronic TE. Our analysis shows how important it is to systematically diagnose patients that present with lateral elbow pain. The clinical characteristics of the three most common causes of chronic lateral elbow pain, meaning, TE, PIN compression, and plicae syndrome were also analyzed. Having adequate knowledge about the clinical aspects of these pathologies can help with a more effective differentiation of the etiology of chronic lateral elbow pain, and with that, a more efficient and cost-effective treatment plan.

Abstract
The present study analyzed the characteristics of phase IV clinical trials in oncology using data from the ClinicalTrials.gov registry. The included trials were conducted between January 2013 and December 2022 and were examined for key characteristics, including outcome measures, interventions, sample sizes, and study design, different cancer types, and geographic regions. The analysis included 368 phase IV oncology studies. An amount of 50% of these studies examined both safety and efficacy, while 43.5% only reported efficacy outcome measures, and 6.5% only described safety outcome measures. Only 16.9% of studies were powered to detect adverse events with a frequency of 1 in 100. Targeted therapies accounted for the majority of included studies (53.5%), with breast (32.91%) and hematological cancers (25.82%) being the most frequently investigated malignancies. Most phase IV oncology studies lacked sufficient power to detect rare adverse events due to their small sample sizes and instead focused on effectiveness. To ensure that there is no gap in drug safety data collection and detection of rare adverse events due to limited phase IV clinical trials, there is a significant need for additional education and participation by both health care providers and patients in spontaneous reporting processes.

Abstract
Introduction Basal cell carcinoma (BCC) is the most common skin cancer in humans, occurring in more than 50% of Caucasians during their lifetime, with a frequency rate that is continually increasing. Material and methods We present a systematic review summarizing the role of transforming growth factor β (TGF-β), cathelicidin, and human β-defensins (HBDs) in the pathogenesis of BCC. The major online databases including PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Google Scholar were searched to extract studies regarding the levels of TGF-β, HBD, and cathelicidin in BCC. Results A total of 14 studies met the inclusion criteria and were included in this systematic review. There were 6 studies that included initially established levels of TGF-β in BCCs. A total of 87 BCCs were analysed, and a common result was that the TGF-β levels increase in the BCCs compared to the control groups. Analogously, 2 studies contained numerical data on HBD levels but with a different in methodology. The level of cathelicidin was established in 108 BCCs and was significantly higher in the BCC group than in the control group. Conclusions The presented review shows evidence that proteins like TGF-β, HBD, and cathelicidin play a role in developing BCC. Protein levels or their expression are elevated in patients with BCC. Furthermore, a critical review of the literature was presented and discussed, highlighting its shortcomings.

Abstract
BACKGROUND The inferior gluteal artery (IGA) is a large terminal branch of the anterior division of the internal iliac artery (ADIIA). There is a significant lack of data regarding the variable anatomy of the IGA. MATERIALS AND METHODS A retrospective study was conducted to establish anatomical variations, their prevalence and morphometrical data on IGA and its branches. The results of 75 consecutive patients who underwent pelvic computed tomography angiography were analysed. RESULTS The origin variation of each IGA was deeply analysed. Four origin variations have been observed. The most common type O1 occurred in 86 of the studied cases (62.3%). The median IGA length was set to be 68.50 mm (lower quartile [LQ]: 54.29; higher quartile [HQ]: 86.06). The median distance from the origin of the ADIIA to the origin of the IGA was set to be 38.22 mm (LQ: 20.22; HQ: 55.97). The median origin diameter of the IGA was established at 4.69 mm (LQ: 4.13; HQ: 5.45). CONCLUSIONS The present study thoroughly analysed the complete anatomy of the IGA and the branches of the ADIIA. A novel classification system for the origin of the IGA was created, where the most prevalent origin was from the ADIIA (type 1; 62.3%). Furthermore, the morphometric properties (such as the diameter and length) of the branches of the ADIIA were analysed. This data may be incredibly useful for physicians performing operations in the pelvis, such as interventional intraarterial procedures or various gynaecological surgeries.

Abstract
BACKGROUND The study aims to determine principal topographical relations between thoracolumbar fascia (TLF) and lateral branches derived from the dorsal (posterior) rami of lumbar spinal nerves and elucidate their potential link to lumbar region pain. The research protocol involves basic TLF morphological description, evaluating its relation to the nerves, and examining general histology. MATERIALS AND METHODS The research was conducted on four male cadavers fixed in 10% neutral buffered formalin. RESULTS The dorsal rami of the spinal nerves branched into medial and lateral divisions. The lateral divisions were about 1 mm thick and mainly visible in the subcutaneous tissue during stratigraphic dissection. They pierced the TLF superficial layer. They descended sidewards and downwards within the superficial fascia (laterally to the erector spinae muscle) to provide sensory innervation to the skin. CONCLUSIONS Anatomical relationships between TLF, deep (intrinsic or true) back muscles, and dorsal rami of the spinal nerves are complex and may be clinically involved in low back pain etiopathogenesis.

Abstract
The aim of the following study was to present and comprehensively describe a case of a bilateral absence of the deep brachial artery (DBA). Furthermore, its embryology and clinical significance will also be discussed. During routine dissection, a 71-year-old male cadaver with a bilateral abnormality in the DBA and its branches was found. The first branch of the brachial artery (BA) was found to be the radial collateral artery, which passed behind the radial nerve. Furthermore, the middle collateral artery originated distal to the radial collateral artery and gave off first a singular, minor muscular branch and then the superior ulnar collateral artery. Later, the preceding nutrient arteries of the humerus and the deltoid branch consecutively branched off from the middle collateral artery. Subsequently, the middle ulnar collateral artery, the inferior ulnar collateral artery, the deltoid artery, the radial artery, and the ulnar artery branched off from the BA, as adapted in the current knowledge regarding the anatomy of the upper extremity. Furthermore, detailed measurements of the distances between the mentioned arteries were carried out. In the present study, a bilateral absence of the DBA was demonstrated. Meta-analysis focusing on the anatomy of this artery has shown how variable its characteristics are. However, our case report is the first in the literature to present this extremely rare variation. Having adequate knowledge regarding the anatomy of the arteries of the proximal arm is of immense importance when performing orthopaedic and reconstructive surgeries in this area.

Synovial plica of the elbow - detailed measurements and how to implicate its relevance in clinical practice. INTERNATIONAL ORTHOPAEDICS 2023; 47:1031-1039. [PMID: 36809417 PMCID: PMC10014655 DOI: 10.1007/s00264-023-05726-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Accepted: 02/07/2023] [Indexed: 02/23/2023]
Abstract
PURPOSE The synovial plica of the elbow is a fold of synovial tissue, which is said to be a remnant of the embryonic septa of normal articular development and is located around the radiocapitellar joint. The objective of the present study was to provide morphometric properties of the synovial plica of the elbow and its relation to surrounding structures in asymptomatic patients. METHODS A retrospective study was conducted to establish the morphometric characteristics of the synovial plica of the elbow. The results of 216 consecutive patients, who for different reasons during the five year period of time underwent magnetic resonance imaging (MRI) of an elbow, were analyzed. RESULTS Plica was found in a total of 161 of 216 elbows (74.5%). The mean width of the plica was set to be 3.00 mm (SD: 1.39). The mean length of the plica was established at 2.91 mm (SD: 1.13). An analysis of sexual dimorphism was also included. Potential correlations were analyzed for each of the categories and age. CONCLUSIONS The synovial plica of the elbow is a clinically relevant anatomical structure. Analyzing the morphometric parameters of the synovial plica is necessary to properly evaluate synovial plica syndrome, which can commonly be confused with other sources of lateral elbow pain such as tennis elbow, oppression of the radial and/or posterior interosseous nerve, or snapping of the triceps tendon. The authors suggest that the thickness of the plica may not be the golden diagnostic feature as there are no statistically significant differences in this parameter between symptomatic and asymptomatic patients. A precise and accurate diagnosis of synovial fold syndrome and/or differentiation from other sources of lateral elbow pain must be performed, as the surgical treatment, even if performed properly, will be unsuccessful because of a misdiagnosed source of pain.

A 3D map of the lingual artery-The perfect tool for transoral robotic surgeries on the base of tongue. Head Neck 2023; 45:872-881. [PMID: 36807690 DOI: 10.1002/hed.27303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 12/13/2022] [Accepted: 01/31/2023] [Indexed: 02/22/2023] Open
Abstract
BACKGROUND Knowledge about the anatomy of the lingual artery (LA) is of immense importance when performing procedures on the base of tongue (BOT). METHODS A retrospective analysis was performed to establish morphometric data of the LA. The measurements were performed on 55 consecutive patients who underwent head and neck computed tomography angiographies (CTA). RESULTS A total of 96 LAs were analyzed. Additionally, a three-dimensional heat map (showing the oropharyngeal region from the lateral, anterior, and superior point of view) of the occurrence of the LA and its branches was created. CONCLUSION The length of the main trunk of the LA was measured to be 31.94 ± 11.44 mm. This reported distance is thought to be a surgical safe zone when performing transoral robotic surgery (TORS) on the BOT because it represents the area where the LA does not give off any major branches.

A complete analysis of the surgical treatment for cubital tunnel syndrome: an umbrella review. J Shoulder Elbow Surg 2023; 32:850-860. [PMID: 36584870 DOI: 10.1016/j.jse.2022.11.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 11/11/2022] [Accepted: 11/20/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND Numerous original studies have been presented regarding various surgical treatments for cubital tunnel syndrome (CubTS). The results of these analyses regarding the different surgical treatments for CubTS frequently differ and, in some cases, contradict each other, creating confusion. Therefore, our umbrella review aimed to summarize the evidence from meta-analyses and systematic reviews regarding the surgical treatments of CubTS, and along with the new, more detailed outcomes, provide an evidence-based tool for surgeons performing these procedures. MATERIALS AND METHODS To perform this umbrella review, a systematic search was conducted for meta-analyses investigating CubTS in PubMed, Scopus, Embase, Web of Science, Google Scholar, Cochrane Library, BIOSIS, and EBSCO medical databases. RESULTS Detailed comparison of surgical outcomes, such as clinical improvement, complications, or reoperation rates, of different treatment methods for CubTS was performed. New risk ratios in all categories were established based on all of the primary studies available in the literature. DISCUSSION The goal of the present umbrella review was to gather and summarize all data about the surgical treatments for CubTS in the available literature and provide new outcomes and an evidence-based tool for surgeons performing these procedures. Each comparison of the surgical techniques has been discussed, and the present study's results were compared with the outcomes of the previous studies.

The anatomy of the uterine artery: A meta-analysis with implications for gynecological procedures. Clin Anat 2023; 36:457-464. [PMID: 36448185 DOI: 10.1002/ca.23983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 11/13/2022] [Accepted: 11/23/2022] [Indexed: 12/03/2022]
Abstract
The uterine artery (UA) is an arterial branch of the internal iliac artery in women, usually arising from the anterior division of the internal iliac artery. However, due to the high variability in the anatomy of the UA, embolization of this vessel may be challenging. Therefore, the objective of this meta-analysis was to provide physicians with transparent data on the anatomy of the UA, using the available data in the literature. Databases such as PubMed, Scopus, Embase, Web of Science, and Google Scholar were searched to find all the relevant studies regarding the UA. A total of 16 articles met the required criteria. The UA was found to originate most frequently from the internal iliac artery as the pooled prevalence was set to be 61.72% (95% CI: 41.31%-80.31%). A pooled prevalence of the UA originating from the umbilical artery was established at 13.93% (95% CI: 2.76%-30.44%). A pooled prevalence of the UA originating from the inferior gluteal artery was set to be 5.22% (95% CI: 0.00%-15.44%). In conclusion, we believe that this is the most accurate and up-to-date study regarding the highly variable anatomy of the UA. The UA originates most frequently from the internal iliac artery (61.72%), however, other origins, such as from the umbilical artery (13.93%) or the inferior gluteal artery (5.22%) may occur. It is hoped that the results of the present meta-analysis will be a helpful tool for surgeons performing pelvic or gynecological surgeries.

How to write an umbrella review? A step-by-step tutorial with tips and tricks. Folia Morphol (Warsz) 2023; 82:1-6. [PMID: 36573368 DOI: 10.5603/fm.a2022.0104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 11/29/2022] [Accepted: 11/30/2022] [Indexed: 12/28/2022]
Abstract
The number of meta-analyses (MA) and systematic reviews (SR) on various medical issues has increased during the last two decades. The MA and SR results may differ from one another due to a number of factors such as inaccurate or diverse searches through the databases, discrepancies in the extraction process or in statistical analysis, among others. Some results may even contradict one another, resulting in confusion among readers. Umbrella reviews (UR) have allowed the collection of all available data on a medical issue into one concise study, making it the source of evidence-based medical knowledge to the highest degree. Furthermore, UR can resolve those problems by collecting all data and taking into account both MA and SR, making it the superior tool for physicians. Although the pros of UR are clear and the overall popularity of these types of study has increased tremendously, there is no available step-by-step guide on how to conduct one. Therefore, the objective of the present study was to provide researchers with a detailed tutorial on how to conduct an UR. UR represent the next major step in the advancement of evidence-based medicine, with great practical potential for physicians looking for the most up-to-date data on their topic of interest. We hope that our step-by-step guide may be a useful tool for researchers conducting UR in the future.

The thyrocervical trunk: an analysis of its morphology and variations. Anat Sci Int 2023; 98:240-248. [PMID: 36350499 PMCID: PMC9902411 DOI: 10.1007/s12565-022-00692-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 10/30/2022] [Indexed: 11/11/2022]
Abstract
The number of studies on the variations of the branching of the TT is scarce, and those works that treat about the different types of the said trunk are oftentimes inconsistent. Therefore, the authors of the present study would like to propose a set of five types of TT, which were created based on observations of 41 computed tomography angiographies (82 TTs). To establish the anatomical variations, their prevalence, and morphometrical data regarding the TT and its branches, a retrospective study was performed. The results of 55 consecutive patients who underwent neck and thoracic computed tomography angiography (CTA) were analyzed. The analysis was performed on a total of 82 TTs of 41 patients, aged 15 to 82 years (mean age: 46 years; SD: 18.4), of which 16 (39.0%) were females, and 25 (61.0%) were males. Initially, 11 types of variations were evaluated, of which types 1-4 constituted 89.0%. Furthermore, a new method of classification of the anatomical variations of the TTs has been established. In this study, the variety of the branching and morphology of the TT was presented, proposing its novel classification based on the five most commonly prevalent types. Types 1 and 2 were the most common, with a prevalence of 26.8% each. This work also provides physicians with crucial data about the morphology of the TT and its branches, which can surely be of use when performing endovascular or reconstructive procedures in the cervical region.

The occipital-vertebral anastomosis revisited. Folia Morphol (Warsz) 2022; 82:615-623. [PMID: 36472395 DOI: 10.5603/fm.a2022.0101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 11/14/2022] [Accepted: 11/14/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND The goal of the study was to provide relevant data about the location and prevalence of the occipital artery-vertebral artery (OA-VA) anastomosis in patients without visible occlusive disease, as well as to thoroughly discuss the clinical significance of these anastomotic channels. Furthermore, the morphometric properties of the OA and its branches were also analysed. MATERIALS AND METHODS A retrospective study was carried out to indicate anatomical variations, their prevalence, and morphometrical data on the OA and its branches. The study was performed on 55 randomly selected computed tomography angiographies (CTA) of the head and neck region. Each CTA result was analysed bilaterally. Thus, 110 results were originally assessed. RESULTS The OA median maximal diameter was demonstrated at 4.85 mm (lower quartile [LQ]: 4.11; upper quartile [UQ]: 5.53) and the median maximal diameter of VA at 3.60 mm (LQ: 2.79; UQ: 4.38). The distances between OA and its branches were also measured giving a median result of 21.73, 30.29, 60.84, 34.88, 18.02, 55.16 mm for the lower and upper sternocleidomastoid branch, meningeal branch, mastoid branch, and descending branch, respectively. The median distance between OA and its first anastomosis was set to be 51.15 mm (LQ: 37.20; UQ: 60.10). Moreover, a set of additional measurements was carried out in order to create a three-dimensional anatomical heat-map of the occurrence of the OA-VA anastomosis. CONCLUSIONS Knowledge about the anatomy of the OA-VA anastomosis might be of immense importance to avoid potentially fatal complications during embolisation of the OA and its branches.

Abstract
BACKGROUND The main objective of the present study was to analyse the morphological variations of the air spaces of the temporal bone, that is, the pneumatized and air-filled spaces of the temporal bone cavities. MATERIALS AND METHODS A total of 99 sides were analysed. Temporal bone pneumatic spaces (TBPS) were defined as the free spaces inside the cavities of the temporal bone filled with air, excluding the volume of the structures present in the investigated region. Total volumes of TBPS were calculated as the sum of total volumes of mastoid air cells (MAC), tympanic cavity (TC), and external auditory canal (EAC). Analyses were performed considering the general population and the female and male subgroups. RESULTS The overall results obtained on Polish population were set as follows: the median total volume of TBPS was demonstrated at 7882.58 mm3 (lower quartile [LQ]: 6200.56 mm3; higher quartile [HQ]: 10393.16 mm3). The median volume of MAC was set at 5813.05 mm3 (LQ: 4224.94 mm3; HQ: 8181.81 mm3). The median of the total volume of the EAC was demonstrated at 1294.36 mm3 (LQ: 1099.68 mm3; HQ: 1627.84 mm3). CONCLUSIONS In the present study, the morphometric properties of the temporal bone cavities were analysed. The results showed that the total volume of the MAC was, on average, lower in women than in men. This should be taken into account when performing procedures on the mastoid, such as mastoidectomies. It is hoped that the results of this study can help reduce potential surgical complications associated with otological procedures.

Abstract
BACKGROUND The goal of the present study was to provide accurate data on the prevalence and morphometrical aspects of the cranio-orbital foramen (COF), which can surely be of use by surgeons performing procedures on the lateral orbit. Furthermore, the embryology and the clinical significance of this osseous structure were thoroughly discussed. MATERIALS AND METHODS Major online medical databases such as PubMed, Scopus, Embase, Web of Science, and Google Scholar were searched to find all relevant studies regarding COF. RESULTS Eventually, a total of 25 studies that matched the required criteria and contained complete and relevant data were included in this meta-analysis. The pooled prevalence of COF was found to be 48.37% (95% confidence interval [CI]: 41.67-55.10%). The occurrence of the COF unilaterally was set to be 71.92% (95% CI: 41.87-96.97%). The occurrence of the COF bilaterally was set at 26.08% (95% CI: 3.03-58.13%). CONCLUSIONS In conclusion, we believe that this is the most accurate and up-to- -date study regarding the anatomy of the COF. The COF is prevalent in 48.37% of the cases, and it is most frequently unilateral (73.92%). Furthermore, the prevalence of accessory COFs was found to be 16.72%. The presence of these foramina may represent a source of haemorrhage that ophthalmic surgeons should be aware of when performing procedures in the lateral part of the orbit.

An aberrant right subclavian artery in a 63-year-old male cadaver. Folia Morphol (Warsz) 2022; 82:726-731.

Abstract
An aberrant right subclavian artery (ARSA), also called "arteria lusoria", is described as a right subclavian artery (RSA) with a retro-oesophageal course that most frequently originates as the most distal branch of the aortic arch. The aim of the following study was to present and thoroughly describe a case of an ARSA, its course, branches, and relation to the surrounding anatomical structures and discuss the clinical significance and embryology of this variant. During routine dissection, a 63-year-old male cadaver with an abnormal variant of the RSA was found. The RSA branched off from the aortic arch as the most distal branch. Subsequently, it coursed posteriorly to the trachea and oesophagus at the level of T2 and T3. Abnormalities in the branching pattern of the RSA were also discovered, such as the right vertebral artery originating from the right common carotid artery as its first branch. This study presents a case of an ARSA, which is a rare anatomical variant of the branches of the aortic arch. The course and branching pattern of an aberrant subclavian artery is quite variable, and each variant can be associated with different possible complications. Furthermore, the ARSA is associated with other cardiovascular anomalies, such as the Kommerell's diverticulum. Therefore, knowledge about the possible variations of this anomaly may be of great importance for physicians who encounter this variant in their practice.

Anatomical variations in the first dorsal compartment of the wrist: meta-analysis. Folia Morphol (Warsz) 2022; 82:766-776. [PMID: 36165900 DOI: 10.5603/fm.a2022.0081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 09/08/2022] [Accepted: 09/09/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND The first dorsal compartment of the wrist includes tendons of abductor pollicis longus (APL) and extensor pollicis brevis (EPB). However, many studies have showed multiple anatomical variations including anomalies in the number of both APL and EPB tendons and presence of intercompartmental fibro-osseous septum. Unfortunately, studies describing those variations are not consistent, hence, the aim of this study was to provide most accurate data about these anatomical variations in the population, using systematic review and meta-analysis. MATERIALS AND METHODS For this purpose, PubMed, Scopus, Web of Science, Embase and a number of minor online libraries were searched. Articles which included exact data about the number of APL or EPB tendons or a presence of intercompartmental septum were qualified for a more precise evaluation. Therefore, out of 1629 studies initially evaluated, 68 were finally included in this meta-analysis. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS A total of 5229 studied wrists have been included in this study. Double APL and single EPB are the most common variations of tendons in the first dorsal compartment, both in cadavers and patients with de Quervain's disease, with no statistically significant differences between those two groups. Presence of intercompartmental fibro-osseus septum is much more common in patients with de Quervain's disease than in cadavers. CONCLUSIONS Our results should improve the awareness of anatomical variations in the first dorsal compartment, which in turn should have impact on treatment of de Quervain's disease in clinical practice.

Abstract
BACKGROUND The petroclinoid ligament (PCL) is an important structure in the petroclival region. The anatomy of the PCL and its relationship with the surrounding structure is highly variable. The aim of this study was to estimate the morphometry, prevalence of mineralization, and anatomy of the PCL. To achieve this, the authors carried out a meta-analysis, including all studies that report extractable data on the PCL. MATERIALS AND METHODS Major online medical databases such as PubMed, Scopus, ScienceDirect, Web of Science, SciELO, BIOSIS, Current Content Connect, Korean Journal Database, and Russian Citation Index were searched to gather all studies regarding the anatomical characteristics, morphometry, and relationship with the anatomical surroundings of the PCL. RESULTS A total of 25 studies were included in this meta-analysis. Data were gathered and analysed in eight categories: (1) mineralization of the PCL, (2) relationship of the abducens nerve with the PCL, (3) relationship of the dorsal meningeal artery with the PCL, (4) shape, number, and continuity of the PCL, (5) PCL anterior attachment, (6) PCL anterior attachment point on bone, (7) PCL posterior attachment point on bone, (8) morphometric features of the PCL. CONCLUSIONS In conclusion, the authors of the present study believe that this is the most accurate and up-to-date meta-analysis regarding the morphology and mineralization of the PCL. The data provided by the present study may be a useful tool for surgeons performing neurosurgical procedures, such as endoscopic transnasal surgeries. Detailed anatomical knowledge of the petroclival region can surely prevent surgical complications when operating in this area.

Abstract
PURPOSE The thoracoacromial trunk (TAT) originates from the second part of the axillary artery and curls around the superomedial border of the pectoralis minor, subsequently piercing the costocoracoid membrane. Knowledge about the location, morphology, and variations of the TAT and its branches is of great surgical importance due to its frequent use in various reconstructive flaps. METHODS A retrospective study was conducted to establish anatomical variations, their prevalence, and morphometric data on TAT and its branches. The results of 55 consecutive patients who underwent neck and thoracic computed tomography angiography were analyzed. A qualitative evaluation of each TAT was performed. RESULTS A total of 15 morphologically different TAT variants were initially established. The median length of the TAT was set at 7.74 mm (LQ 3.50; HQ 13.65). The median maximum diameter of the TAT was established at 4.19 mm (LQ 3.86; HQ 4.90). The median TAT ostial area was set to 13.97 mm (LQ 11.70; HQ 18.86). To create a heat map of the most frequent location of the TAT, measurements of the relating structures were made. CONCLUSION In this study, the morphology and variations of the branching pattern of the TAT were presented, proposing a new classification system based on the four most commonly prevalent types. The prevalence of each branch arising directly from the TAT was also analyzed. It is hoped that the results of the present anatomical analysis can help to minimize potential complications when performing plastic or reconstructive procedures associated with TAT.

Abstract
BACKGROUND Divided zygoma (DZ) is an important structure in the midfacial region. The anatomy of DZ is poorly researched, but knowledge about this entity could be useful during posttraumatic facial reconstructions. The aim of this study was to estimate the prevalence and anatomy of DZ in different regions around the world. Therefore, the authors performed a meta-analysis, including all studies that report extractable data on the DZ. MATERIALS AND METHODS The main online medical databases such as PubMed, EBSCO, ScienceDirect, Web of Science, SciELO, BIOSIS, Current Content Connect, Korean Journal Database and Russian Citation Index, were utilised to gather all studies on anatomical characteristics, prevalence, symmetry, and a number of divisions of zygomatic bone. RESULTS A total of 20 studies were included in this meta-analysis. Data were grouped and analysed in five categories: (1) prevalence of DZ bone, (2) prevalence of DZ skulls, (3) gender prevalence of DZ with sides, (4) divisions of zygomatic bone, (5) symmetry of DZ. CONCLUSIONS In conclusion, the authors of the present study believe that this study can be considered an up-to-date meta-analysis regarding the prevalence, divisions, and symmetricity of the DZ. The data provided by the present study may be useful information for physicians in recognizing the DZ of the fracture and may be important information during zygomatic bone osteotomy. Detailed anatomical knowledge of the midfacial region can prevent surgical complications when operating in this area.

Abstract
INTRODUCTION The number of studies on the anatomy of the costocervical trunk (CCT) is scarce, and the actual prevalence of this structure is unknown. Therefore, the authors of the present study would like to propose a set of four types of CCT, which were created based on observations of computed tomography angiographies (75 CCTs). MATERIALS AND METHODS A retrospective study was conducted to establish variations and the morphometric properties of the CCT. The results of 55 consecutive patients who underwent neck and thoracic computed tomography angiography (CTA) were analyzed in March 2022. RESULTS The analysis was performed on a total of 75 CCTs. Of these, 32 were from women (42.7%) and 43 were from men (57.3%). Branching variations of each CCT were thoroughly analyzed. A classification of the branching pattern of the CCTs was made and consisted of 4 types. CONCLUSION In the present study, the variety of branching and morphology of CCT was analyzed, proposing its novel classification based on the four most frequently observed types. Type 1 was the most prevalent (76.1%), having a similar origin and branching pattern as described in the major anatomical books. CCT was found to be absent in 23.94% of the cases, making it a somewhat less consistent branch of the SA. Understanding the variability of the anatomy of the CCT can be a great tool for physicians performing endovascular procedures in the cervical region. This article is protected by copyright.

Abstract
The presence of multiple renal arteries is the most common form of vascular anomalies found in donor kidneys. In rare cases, small renal polar arteries may be found. They can be anastomosed with deep inferior epigastric arteries, resulting in vascular augmentation of transplanted kidneys and contributing to better graft function. Renal perfusion may be increased via 2 types of vascular reconstruction known as "turbocharging" and "supercharging". Turbocharging uses vascular sources within the same organ area, whereas supercharging uses distant vascular sources. Using additional vessels can either complicate the surgery or, contradictorily, ease the way of procedure. This case study presents a kidney transplant during which arterial anastomosis between deep inferior epigastric artery and small polar renal artery was performed.

A left circumflex aorta with a displaced thoracic duct in a 94-year-old male cadaver: a case report with discussion on embryology. Folia Morphol (Warsz) 2022; 82:400-406. [PMID: 35481702 DOI: 10.5603/fm.a2022.0043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 03/28/2022] [Accepted: 03/29/2022] [Indexed: 11/25/2022]
Abstract
A left circumflex aorta (LCA) is an extremely rare variation of the thoracic aorta. It is distinguished by a retroesophageal descending aorta that subsequently travels down the right side of the thoracic vertebrae towards the aortic hiatus. Nonetheless, its embryological origin ought not to be overly generalised, but each case should be considered individually due to its unique vascular patterns. This study presents a description of a LCA in a 94-year-old male cadaver. The dissection revealed the descending aorta posteriorly from the trachea and oesophagus and then laterally on the right from the thoracic vertebral bodies. The branching pattern of the aortic arch was typical, so was the course of the left and right recurrent laryngeal nerves. However, the thoracic duct was placed on the right, and drained into the right internal carotid vein. Due to the normal appearance of the ascending part and the arch of the aorta, it is safe to presume that the variation originated from the persistent right dorsal aorta, with the retroesophageal part from the persistent left dorsal aorta. Detailed understanding of the variations of the thoracic aorta, and the anomalies associated with the LCA, can help to improve management of these conditions, and with that, improve patients' overall outcomes. Patients with a LCA, or another vascular ring, can either be asymptomatic or present with oesophageal and/or tracheal compression symptoms. Management of this anomaly consists namely of ligation of the patent ductus arteriosus/ligamentum arteriosum and aortic uncrossing.

The middle anorectal artery - a systematic review and meta-analysis of 880 patients / 1905 pelvic sides. Clin Anat 2022; 35:934-945. [PMID: 35474241 DOI: 10.1002/ca.23898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 04/23/2022] [Accepted: 04/25/2022] [Indexed: 11/12/2022]
Abstract
INTRODUCTION The middle anorectal artery (MAA) is considered to supply the middle and lower parts of the rectum however its prevalence and point of origin vary across the literature. Clinical importance of the MAA becomes evident in the total mesorectal excision during the colorectal surgery of rectal cancer in both sexes, as well as interventional radiology procedures utilizing the prostatic vasculature in males. MATERIALS AND METHODS Major electronic medical databases were investigated for terms pertaining to the MAA and its associated variations. Compatible data regarding the artery's prevalence, laterality, origin, and distribution in both sexes was acquired. The risk of bias within the studies was assessed utilizing the AQUA tool. RESULTS In total, 28 works (n=880 patients / 1905 pelvic sides) were included in this systematic review and meta-analysis, and their publication date ranged from 1897 until 2021. The overall pooled prevalence estimate for the MAA was 59.8% of the patients, and 55.2% of the pelvic sides studied. The vessel was identified more frequently in cadaveric pelvic sides evaluations (79.3%). The artery was found bilaterally more often (56.7%), and most commonly originated from the internal pudendal artery (50.3%). Anastomoses between the MAA and the other anorectal arteries were reported in 78.1%. CONCLUSIONS The MAA is predominantly a present vessel, with various point of origin. Its direct clinical significance is yet to be discovered in larger study samples, providing more detailed and unified reports of its anatomical features, especially regarding its branches.

Outcomes of kidney transplantation during the SARS-CoV-2 pandemic at one centre in Poland. Transplant Proc 2022; 54:888-889. [PMID: 35637012 PMCID: PMC8995324 DOI: 10.1016/j.transproceed.2022.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 02/16/2022] [Accepted: 03/10/2022] [Indexed: 12/04/2022]
Abstract
The SARS-CoV-2 pandemic has significantly affected the number of transplanted organs worldwide. The rules and restrictions related to transplantation activities in Poland are included in the updated guidelines of the Polish Organizational and Coordination Centre for Transplantation. Our clinic faces the same problems as the rest of the hospitals in the country. Not only are the number of recipients falling, but there are also numerous restrictions concerning, among other things, qualification of donors and recipients and even preparation of centers for long-term care in the event of infection of organ recipients with the SARS-CoV-2 virus. Statistics showed, after an initial fall in the number of kidneys transplanted, a temporary normalization during the summer months, only to record a fall again with an increase in new cases of COVID-19. A total of 29 kidneys were transplanted at our center between March and December 2020. Kidney transplantation is not only linked to the operation itself, but also to the follow-up care of the recipients. Reduced immunity among recipients due to immunosuppressive treatment as well as comorbidities among recipients contribute to this group being at increased risk of symptomatic SARS-CoV-2 infection. The number of cases of SARS-CoV-2 infection among kidney transplant recipients at our center was 7, of which we recorded 2 deaths due to COVID-19 in the period after kidney transplant. Postoperative complications probably related to previous SARS-CoV-2 infection occurred in 1 patient.

The deep brachial artery - a meta-analysis of its origin and diameter with a review of the literature. Clin Anat 2022; 35:838-846. [PMID: 35313051 DOI: 10.1002/ca.23853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/15/2022] [Accepted: 03/18/2022] [Indexed: 11/07/2022]
Abstract
The deep brachial artery (DBA) is the first and largest branch of the brachial artery. Multiple variations of the DBA's origin, termination, and diameter have been reported in the literature. Major online medical databases such as PubMed, Scopus, Embase, Web Of Science, and Google Scholar were searched in order to find all studies considering origin variations and the diameter of the DBA. The prevalence of the DBA originating directly from the axillary or brachial artery was shown to be 92.87%. DBA originating indirectly from the axillary or brachial artery, as a common trunk with other arteries, was found to be 7.13%. The mean diameter of the DBA was shown to be 2.05 mm. The authors of the present study believe that this is the most accurate and up-to-date meta-analysis considering origin patterns and the diameter of the DBA. Additionally, this study contains a comprehensive literature review in which current detailed anatomical knowledge concerning the DBA was gathered. The results of this study could provide a helpful tool for physicians, especially surgeons, dealing with an upper limb in their daily practice. This article is protected by copyright.

Abstract
The dorsal capsule of the wrist and the DCSS may play a significant role in the conduction of nerve signals transmitted from proprioceptors present in SL to PIN, which is located above the dorsal capsule. Hence, this study aimed to determine if nerve fibers of PIN penetrate inside the dorsal capsule. The dorsal capsules of the wrist were dissected from both sides from 15 cadavers. Eventually, 30 dorsal capsules were dissected. It can be concluded that the PIN nerve fibers penetrate the dorsal capsule of the wrist, as the penetration was noticeable in every part evaluated. The present study proves that afferent fibers from the mechanoreceptors of the SLIL potentially pass through the DCSS and subsequently through the dorsal capsule of the wrist to the PIN. This knowledge can surely be of great use for hand surgeons that perform procedures on the dorsal wrist.

Termination points of the facial artery-A meta-analysis. Clin Anat 2021; 35:469-476. [PMID: 34851525 DOI: 10.1002/ca.23817] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2021] [Revised: 11/28/2021] [Accepted: 11/28/2021] [Indexed: 11/11/2022]
Abstract
The facial artery (FA) is the main artery supplying the anterior face, making this artery a very important structure to consider while performing plastic and reconstructive procedures. The literature shows discrepancies in anatomical classifications and the frequency of occurrence of individual variations. Therefore, the goal of this meta-analysis is to provide surgeons with helpful knowledge about the variety of the termination of FA. Articles with data about the termination of the FA were found in major online medical databases such as PubMed, Scopus, Embase, Web Of Science, and Cochrane Library. A total of 1346 articles were initially evaluated by two independent reviewers. Out of those, 24 articles matched the required criteria, and were used in this meta-analysis. A total of 2119 studied FAs were included in this study. The FA termination patterns were divided into five previously classified types. The data show that the FA terminates most frequently as the lateral nasal or angular artery with the prevalence for this group being 69.81% (95% confidence interval [CI]: 59.83%-78.94%). Authors believe that this is the most accurate and up to date study regarding termination patterns and the prevalence of the FA. The results of this meta-analysis could provide a helpful tool for surgeons preforming plastic and cosmetic procedures, especially when injecting dermal fillers or choosing and preforming facial flaps. Detailed anatomical knowledge about the FA may prevent potential surgical complications.
