Abstract
Head and neck defects present a unique challenge in reconstructive surgery due to the complex anatomy of this area. Different defects often require a variety of reconstructive techniques. The superficial circumflex iliac artery perforator (SCIP) flap is particularly notable for its versatility in this context. It provides a thin, pliable skin island that can be integrated with bone, muscle, fascia, and other structures. Additionally, the morbidity associated with the donor site of the SCIP flap is generally low and well tolerated. This article offers a comprehensive overview of the evolution of this technique.

Abstract
BACKGROUND In the surgical treatment of head and neck locally advanced malignancies, microvascular free flaps represent the most valuable solution to reconstruct the tissue defect after resection of the primary neoplasm. In particular, microvascular free flaps allow to restore the functional and aesthetical features of the head and neck compartments. The superficial circumflex iliac perforator (SCIP) flap represents, as an evolution of the groin flap, a valid alternative to the radial fasciocutaneous free (RFFF) flap or the anterolateral thigh (ALT) flap. METHODS This systematic review adhered to the recommendations of the Preferred Reporting Items of Systematic Reviews and Meta-analysis (PRISMA) 2009 guidelines. A computerized MEDLINE search was performed using the PubMed service of the U.S. National Library of Medicine ( www.pubmed.org ) and Scopus database ( www.scopus.com ). Two authors screened the articles, then selected and extracted data on malignancies characteristics, reconstructive techniques, outcomes, and complications. RESULTS A total of 25 articles were selected and reviewed among the 39 identified through the search string. Six out of the selected 25 articles were case reports, while the remaining 19 articles were retrospective case series. The whole study population was represented by 174 oncologic patients undergoing ablation of a head and neck tumor and reconstruction with a SCIP flap. The site of reconstruction was the oral cavity in 125 (71.0%) patients, being the tongue the most common subsite in 73 (41.5%) patients, the pharynx in 10 (5.7%) cases, the larynx in 3 (1.7%) and head and neck skin in 36 (20.4%) patients. Only two cases of total flap loss were reported. Partial flap loss or shrinkage requiring minor surgical revisions was observed in 11 patients (6.32%). Primary closure of the donor site was achieved in the whole study population, according to the available data. CONCLUSIONS In head and neck postoncological reconstruction, despite the caliber and the length of the pedicle, SCIP flap offers a pliable and thin skin paddle, allowing single-stage resurfacing, medium to large skin paddle, possibility of composite-fashion harvest and a well-concealed donor site.

Use of supermicrosurgery in craniofacial and head and neck soft tissue reconstruction: a systematic review of the literature and meta-analysis. Br J Oral Maxillofac Surg 2024; 62:140-149. [PMID: 38290861 DOI: 10.1016/j.bjoms.2023.11.014] [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: 11/09/2023] [Accepted: 11/28/2023] [Indexed: 02/01/2024]
Abstract
Supermicrosurgery is an evolving approach in the reconstruction of head and neck (HN) and craniofacial (CF) defects. This systematic review aims to evaluate the use of supermicrosurgery for arterial or combined arterial and venous anastomoses in the reconstruction of HN and CF soft tissue defects, and the associated success, total complication, and reoperation rates. A literature search was conducted on PubMed, Dynamed, DARE, EMBASE, Cochrane, and British Medical Journal (BMJ) electronic databases (PROSPERO ID: CRD42023476825). Nine studies fulfilled the inclusion criteria with 35 patients who underwent soft tissue reconstructive procedures using supermicrosurgery. Twenty-one flaps were performed on 20 patients (57.1%) with the remaining 15 patients (42.9%) undergoing supermicrosurgical replantation. The most common pathology requiring reconstruction was HN trauma (n = 16, 45.7%) followed by malignancy (n = 15, 42.9%). The pooled success rate for supermicrosurgery was 98% (95% CI 90 to 100, p = 1.00; I2 = 0%). The cumulative complication rate across all the studies was 46% (95% CI 13 to 80, p < 0.01; I2 = 0%), and the pooled rate of reoperation was 1% (95% CI 0 to 8, p = 0.23; I2 = 24%). The use of supermicrosurgery for HN and CF soft tissue reconstruction has an overall success rate of 98%, which is commensurate with traditional microsurgery for HN reconstruction. Complication and reoperation rates are comparable to previous literature. This study confirms the feasibility of supermicrosurgery as a safe and reliable reconstructive option for HN and CF defects.

Abstract
Introduction Microvascular anastomosis has traditionally been executed with a perpendicular transection through the vessel at the widest diameter to increase circumference and thus increase blood flow while decreasing resistance. In Chen's 2015 article, it was suggested that an "open Y" would improve vessel size match, and Wei and Mardini discuss angled transections of the vessels. This project aims to explore the geometric configurations feasible at the anastomotic transection and mathematically model the resulting hypothetical increases in circumference. Materials and Methods The mathematical models were theoretically developed by our team. The formulas model increases in circumference of the transection at different distances in relation to the bifurcation of a blood vessel, as well as changes in circumference at different transection angulations. An in vitro exploration as to the anastomotic feasibility of each geometric cut was completed on ten poultry tissue specimens. Results The mathematical models demonstrated the change in vessel circumference, with multiple geometric designs calculated, best shown through diagrams. For example, if the vessel width is 1 mm, the distance from the increasing vessel diameter to the final bifurcation is 1 mm, and the bifurcation angle is 45°, the circumference of the transected vessel increases by 82.8%. Models of transections at different angulations, for instance 30°, 45°, and 60°, yield an increase in elliptical circumference of 8.0%, 22.5%, and 58.1%, respectively. Additional derivations calculate the elliptical circumference at any angle in a single vessel, and at any angle in a bifurcating vessel. Conclusion The theoretical and clinical aim of this project is to increase awareness of the anastomotic creativity and mathematically demonstrate the optimal anastomotic geometry, which has not been objectively explored to our knowledge. An in vivo study would further support clinical improvements, with the aim to map postoperative fluid dynamics through the geometric anastomoses.

Abstract
BACKGROUND Supermicrosurgery is a technique that allows microsurgeons to accomplish dissections and anastomoses of vessels and nerve fascicles with diameters of ≤0.8 mm. Considering the potential benefits of this technique and limited literature synthesizing the outcomes of supermicrosurgery, the aim of this study was to summarize the available evidence of reconstructive supermicrosurgery and to estimate the success rate. METHODS We conducted a comprehensive search across PubMed, Scopus, Embase, and Web of Science. We included patient-based studies reporting on procedures for soft-tissue reconstruction with free flaps specifying the use of supermicrosurgery. We excluded studies reporting on lymphatic surgery, solely peripheral nerve surgery, and tissue replantation. Our primary endpoint was to calculate the flap success rate. Pooled estimates were calculated using a random-effects meta-analytic model. RESULTS Forty-seven studies reporting outcomes of 698 flaps were included for qualitative synthesis. Overall, 15.75% of flaps were used for head and neck, 4.4% for breast and trunk, 9.3% for upper limb, and 69.2% for lower limb reconstruction. The most used flap was the superficial circumflex iliac artery perforator flap (41.5%). The overall flap success rate was 96.6% (95%CI 95.2%-98.1%). The cumulative rate of partial flap loss was 3.84% (95%CI 1.8%-5.9%). The overall vascular complication rate resulting in complete or partial flap loss was 5.93% (95%CI 3.5%-8.3%). CONCLUSIONS Supermicrosurgery displays a high success rate. Further studies are necessary to explore the true potential of supermicrosurgery. This technique reformulates the boundaries of reconstructive surgery due to its extensive application.

Abstract
Most of the articles on the groin flap were published in the period from 1975 to 2010, from 2015 to 2022, the SCIP flap surpassed the groin flap in the number of publications. According to the results of a literature search in PubMed and RINC, 30 articles were found and selected, including 288 flaps from the iliac region. The length of the vascular pedicle, the diameter of the vessels, the complications, the prevalence of the flap in the reconstruction of the head and neck, the thickness and the size of the flap were evaluated. Both of these flaps have the same nutrition, but different levels of dissection. In comparison with the groin flap, the SCIP flap has a longer vascular pedicle, which can be enlarged due to new techniques, which also allows it to be used as an ultra-thin flap, and it reduces the need for secondary procedures for defatting and reduces the risks of the complications in the donor area. The thickness of the SCIP flap is less than the groin one, which, according to the author, increases the aesthetic level of operations in the facial area in the case of the texture and color of the flap. Vascular anatomy of the SCIP flap is variable, therefore, the use of preoperative planning is necessary. Despite this, complications in the donor or recipient area during reconstruction with a SCIP flap are minimal. It has been proved that the SCIP flap is versatile and safe in all aspects of reconstruction. It can be concluded that the SCIP flap should be considered as a «workhorse» in reconstructive microsurgery of soft tissues of the throat and oral cavity.

Abstract
Recipient vessel selection for free flap reconstruction depends on numerous factors and may be limited due to previous treatment. Currently, little evidence is available regarding the anatomy and reconstructive potential of the common facial vein (CFV), a tributary of the internal jugular vein (IJV). The aim of this project was to determine the diameter of the CFV at various points along its course and identify suitable landmarks to locate the CFV, to consider the vessel as a potential recipient vein in free flap reconstruction. A cadaveric study was conducted by dissecting 17 embalmed neck hemi-sections in the Keele University Medical School Anatomy Suite. Our intent was to describe the gross anatomy of the CFV in terms of diameter and relation to surrounding structures. We found the mean diameter of the CFV to be 5.9 (± 1.8) mm at its termination into the IJV. We also found the mean distance of the CFV termination into the IJV from the level of the hyoid bone was 8.0 (± 4.0) mm. The diameter of the CFV could accommodate for end-to-end anastomoses to be formed with the IJV system. The diameter also suggests the vein to be appropriate for microvascular anastomosis with commonly used free flaps. The results propose that the CFV can be found within 12 mm of the level of the hyoid bone, knowledge of which could reduce operative time and site morbidity. These findings support the CFV as a potential recipient vein in free flap reconstruction of the head and neck.

Abstract
This study was designed to compare the outcome and analyze the operation-related risk factors in free flap reconstruction for patients with primary and recurrent head and neck cancers. A 1:1 propensity score-matched analysis of the microsurgery registry database of the hospital. The primary outcome of the free flap reconstruction had a higher failure rate in the recurrent group than the primary group (5.1% vs. 3.1%, p = 0.037). Among the 345 pairs in the matched study population, there were no significant differences between the primary and recurrent groups regarding the rate of total flap loss (3.5% vs. 5.5%, p = 0.27) and secondary outcomes. This study revealed that free flap reconstruction had a higher failure rate in the recurrent group than the primary group, but such a difference may be attributed by the different patient characteristics.

Abstract
BACKGROUND Reconstruction after esophagectomy is conventionally performed with a gastric conduit. However, in cases where a gastric conduit is unavailable, reconstructive procedures vary in terms of flap type, operative timing, and conduit route. Single-stage surgery is associated with a long operation time and high surgical stress, resulting in perioperative mortality. Recent advances in reconstructive microsurgery have made free intestinal flap transfer safe and reliable. Therefore, to overcome the shortcomings with previous methods, we performed 2-stage surgery involving free jejunum/ileum transfer for reconstruction after esophagectomy. PATIENTS AND METHODS From 2010 to 2018, 42 free jejunum/ileum flaps were transferred for reconstruction after esophagectomy in 41 patients. The diagnosis was esophageal cancer in 38 patients. All operations were performed in 2 stages. In most cases, total esophagectomy was performed in the first operation. The cervical stump of the esophagus was sutured to the cervical skin, creating an esophagostomy in the left neck. About 4 to 7 weeks after the first operation, the second operation was performed. The free jejunum/ileum flap was transferred through the subcutaneous route. Microvascular anastomosis was performed with the internal mammary artery and internal mammary vein, transverse cervical artery, internal and external jugular veins (internal jugular vein and EJV, respectively), and cephalic vein. The mean follow-up duration was 20 months. RESULTS Free jejunum/ileum transfer was performed as the first operation in 4 cases and as the second operation in 38 cases. A free jejunal flap was used in 36 cases and free ileal flap was used in 6 cases. The recipient arteries were the internal mammary artery in 38 cases and transverse cervical artery in 4 cases. The recipient veins were the internal mammary vein in 15 cases, cephalic vein in 13 cases, EJV in 10 cases, and internal jugular vein in 10 cases. The flaps survived in all cases, except 1 case (41/42, 97.6%). The complications were anastomotic leakage of the flap in 9 cases, respiratory complications in 10 cases, and ileus in 2 cases. Perioperative mortality was not noted. CONCLUSIONS Two-stage surgery using free jejunum/ileum flap transfer is a safe and reliable option for esophageal reconstruction in cases where gastric pull-up is unavailable.

Abstract
INTRODUCTION The clavicular region is acknowledged as one of the most suitable donor sites for reconstruction of the face or neck. Recently, a free thoracoacromial artery (TAA) perforator (TAAP) flap was reported as a new option for reconstruction of the face. However, the TAAP flap has several drawbacks including tedious intramuscular dissection of the pedicle and loss of availability of a pectoralis major flap as a bailout option in case of cancer recurrence. We performed an anatomical study of the TAAP and developed a novel TAA "true-perforator" flap, in which we can preserve the main trunk of the TAA. PATIENTS AND METHODS Anatomical study of the TAAPs was performed in 6 patients while elevating a deltopectoral flap or a pedicled TAAP flap. Location and diameter of the perforators were recorded. Based on these anatomical findings, we developed a novel free TAA true-perforator flap, which we used for the reconstruction of a facial defect after cancer resection. RESULTS The most dominant TAAP was identified 4.8-cm (4 to 7-cm) caudally from the upper border of the deltopectoral triangle along the cephalic vein and 1.7-cm (0.5 to 2-cm) medially from the cephalic vein. The diameter of the TAAPs at the level of fascial penetration was 0.78-mm (0.6 to 1.0-mm). The pedicle could be elongated up to 3-cm with proximal dissection. Clinical case showed a satisfactory aesthetic result with minimal donor-site morbidity. CONCLUSIONS A free TAA true-perforator flap can be a new option for the reconstruction of the face with many advantages including reduced donor-site morbidity and satisfactory aesthetic outcome.

Use of the Distal Facial Artery (Angular Artery) for Supermicrosurgical Midface Reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e1978. [PMID: 30881816 PMCID: PMC6416107 DOI: 10.1097/gox.0000000000001978] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2018] [Accepted: 08/22/2018] [Indexed: 11/26/2022]
Abstract
Supplemental Digital Content is available in the text. Background: In free-flap reconstruction of the midface, options for the recipient artery are quite limited; the superficial temporal artery and the facial artery are the most commonly used arteries. We report our approach for the use of the angular artery (the terminal branch of the facial artery) as the recipient artery in free-flap reconstruction of the midface. Methods: Nine patients with midface defects underwent free-flap reconstructions using the angular artery as the recipient artery. Identification and marking of the facial artery were performed preoperatively using handheld Doppler ultrasound. The angular artery was located through an incision made on the side of the nose. When present, a vena comitans of the facial artery or any subcutaneous vein in the vicinity of the defect was used as the recipient vein. In other cases, the facial vein in the submandibular region was chosen as the recipient vein, using a vein graft. Results: The average diameter of the angular artery was 0.9 mm (range, 0.7–1.0 mm). In all cases, arterial anastomosis was performed in an end-to-end fashion, and flaps survived completely. In 4 cases, a vein graft was used to bridge the pedicle vein and the facial vein. Conclusions: Although supermicrosurgical skills may be required for its anastomosis, the angular artery is an anatomically consistent artery, which is suitable for use as the recipient artery in free-flap reconstruction of the midface. Use of the angular artery as the recipient artery allows shorter flap pedicles and decreases the number of vein grafts necessary.

Abstract
Background Although free jejunal transfer is an established and reliable procedure for reconstruction after total pharyngolaryngectomy (TPL), vascular thrombosis remains a surgical challenge. To reduce the risk, a double-pedicled free jejunal flap transfer has been attempted using a root jejunal artery and an arcade artery, although several drawbacks exist. The vasa recta are terminal straight vessels that arborize from an arcade artery without branching. We present a novel double-pedicled free jejunum transfer using vasa recta anastomosis. Methods Between 2011 and 2015, we performed 14 double-pedicled free jejunal flap transfers for reconstruction after TPL. Vasa recta were used for second arterial anastomosis in 5 out of 14 patients. Others include a root artery in three patients and an arcade artery in six patients. Indocyanine green (ICG) angiography was performed to confirm the patency and perfusion of the entire flap by the second artery alone. Results The flaps survived completely in all cases. The vasa recta (average diameter; 0.8 mm) were anastomosed to the superior thyroid artery and transverse cervical artery in four and one cases, respectively. Supramicrosurgical end-to-side anastomosis was performed in two cases. ICG angiography showed sufficient perfusion of the entire flap with the second artery alone in all cases. Conclusion As vasa recta were confirmed as being capable of perfusing the entire flap up to 25 cm, the double-pedicle method using vasa recta might be an option to reduce the risk of flap necrosis, particularly in high-risk patients.

Abstract
Plastic and reconstructive surgery relies on the knowledge of angiosomes in the raising of microsurgical flaps. Growing interest in muscle-sparing perforator flaps calls for reliable methods to assess the clinical feasibility of new donor sites in anatomical studies. Several injection techniques are known for the evaluation of vascular territories. Indocyanine green-based fluorescence angiography has found wide application in the clinical assessment of tissue perfusion. In this article, the use of indocyanine green-based fluorescence angiography for the assessment of perforasomes in anatomical studies is described for the first time.
