Chaudhary G, Amipara H, Singh P. Is YouTube a reliable source of information for temporomandibular joint ankylosis? Oral Maxillofac Surg 2024:10.1007/s10006-024-01270-x. [PMID: 38910212 DOI: 10.1007/s10006-024-01270-x] [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: 11/01/2023] [Accepted: 06/17/2024] [Indexed: 06/25/2024]
Abstract
PURPOSE In the digital era, the internet is the go-to source of information, and patients often seek insights on medical conditions like TMJ ankylosis. YouTube, a popular platform, is widely used for this purpose. However, YouTube's lack of regulation means it can host unreliable content. Hence, the primary objective of this study is to assess the scientific quality of YouTube videos concerning TMJ ankylosis. MATERIALS AND METHODS This study analyzed 59 TMJ ankylosis-related videos. Two Oral and Maxillofacial Surgery specialists assessed these videos. Data on the video source, duration, upload date, the time elapsed since upload, total views, likes, dislikes and comments, Interaction index, and viewing rate were collected and analyzed. Video quality was assessed using the Global Quality Scale (GQS) and the Quality Criteria for Consumer Health Information (DISCERN), comparing health professionals and non-health professionals. RESULTS Health professional's videos were better in terms of GQS 3.21 ± 0.94 and DISCERN score 3.03 ± 0.75 as compared to the non-health professional videos GQS 3.0 ± 1.04, and DISCERN 2.81 ± 1.13. Health professional group videos had more reliability and better quality than the non-health professional group (p < 0.01). CONCLUSION YouTube should not be relied on as a trustworthy source for high-quality and reliable information regarding TMJ ankylosis videos. Healthcare professionals must be prepared to address any ambiguous or misleading information and to prioritize building trustworthy relationships with patients through accurate diagnostic and therapeutic processes.

Abstract
AIM To evaluate and compare outcomes of patients with temporomandibular joint ankylosis (TMJA) treated by gap arthroplasty, costochondral graft, and total alloplastic joint reconstruction. METHODOLOGY A retrospective cohort study reviewed and analyzed data from patients with TMJA from January 1, 2009 to December 31, 2019, at the Maxillofacial and Oral Surgery Department, University of the Witwatersrand. Patients with TMJA were treated either with gap arthroplasty, costochondral graft, or total alloplastic joint reconstruction. Data collected included age, sex, etiology of ankylosis, sides involved, preoperation and postoperation mouth opening (MO), treatment type, complications, and revision surgery. Patients were followed up for at least 18 months after the surgical procedure. Comparison of means across the treatment groups was analyzed using paired t tests or analysis of variance test. A P value of less than 0.05 was considered statistically significant. RESULTS The study sample comprised of 36 patients [bilateral, n=22; unilateral, n=14 (21 male, 15 female)]. Trauma was the most common etiology (n=27, 75%), followed by chronic infections (n=4, 11.11%) and juvenile arthritis (n=3, 8.3%). A paired t test revealed no statistical significance between treatment modality and postoperative MO and complications over 18 months (P=0.5316 and P=0.426, respectively). The mean MO increased from 4 to 28 mm. Reankylosis was the most common complication (n=5). CONCLUSIONS All 3 treatment options yield acceptable outcomes in patients with TMJA. Irrespective of surgical technique, early postoperative exercises, active physiotherapy, and follow-up are imperative for successful rehabilitation and prevention of reankylosis.

Abstract
BACKGROUND Phosphorous necrosis of the jaw (PNJ) exhibits similar clinical and pathological features as medical-related osteonecrosis of the jaw (MRONJ). This study aims at comparing the similarities and differences between PNJ and MRONJ regarding pathological features and to provide a theoretical basis for the clinical diagnosis and management of PNJ. MATERIAL AND METHODS A retrospective analysis was conducted to assess clinical differences among 38 PNJ patients and 31 MRONJ patients, who were diagnosed and treated between January 2009 and October 2022. Pathological alterations in bone tissue were evaluated using EDS, H&E, Masson, and TRAP staining on five specimens from both MRONJ and PNJ cases; furthermore, immunohistochemistry was used to determine the expression levels of OPG, RANKL, and Runx2. The mandibular coronoid process was removed from individuals with temporomandibular joint ankylosis to serve as a control. RESULTS CBCT imaging demonstrated necrotic bone formation in block, strip, or plaque shapes. EDS analysis showed that the calcium/phosphorus ratio in the bone tissue of PNJ and MRONJ was significantly lower than that of the control group (P < 0.05). Additionally, staining indicated reduced osteoblast counts, disrupted bone trabecular structure, and decreased collagen fiber content in the bone tissues of PNJ and MRONJ. Immunohistochemistry demonstrated that RANKL expression was significantly lower in MRONJ compared to PNJ and control groups (P < 0.05). Conversely, Runx2 expression was significantly higher in PNJ than in MRONJ and control groups (P < 0.05), and there was no significant difference in OPG expression. CONCLUSION PNJ and MRONJ demonstrate comparable clinical manifestations and pathological traits, although disparities may exist in their underlying exhibit comparable clinical manifestations, pathological traits, and molecular mechanisms.

[PMID: 37951521 DOI: 10.1016/j.bone.2023.116955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 10/22/2023] [Accepted: 11/04/2023] [Indexed: 11/14/2023]
Abstract
INTRODUCTION Arthrogryposis multiplex congenita (AMC) is a heterogeneous group of disorders associated with decreased fetal movement, with a prevalence between 1/3000 and 1/5200 live births. Typical features of AMC include multiple joint contractures present at birth, and can affect all joints of the body, from the jaw, and involving the upper limbs, lower limbs and spine. The jaws may be affected in 25 % of individuals with AMC, with limited jaw movement and mouth opening. Other oral and maxillofacial deformities may be present in AMC, including cleft palate, micrognathia, periodontitis and delayed teething. To our knowledge, oral and maxillofacial abnormalities have not been systematically assessed in individuals with AMC. Therefore, this scoping review was conducted to identify, collect, and describe a comprehensive map of the existing knowledge on dental and maxillofacial involvement in individuals with AMC. METHODOLOGY A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. The PRISMA guidelines for scoping reviews were followed and databases were searched for empirical articles in English and French published until October 2022. We searched MEDLINE, Embase, Web of Science and ERIC databases. Two authors independently reviewed the articles and extracted the data. RESULTS Of a total of 997 studies that were identified, 96 met the inclusion criteria and were subsequently included in this scoping review. These 96 studies collectively provided insights into 167 patients who exhibited some form of oral and/or maxillofacial involvement. Notably, 25 % of these patients were within the age range of 0-6 months. It is worth highlighting that only 22 out of the 96 studies (22.9 %), had the primary objective of evaluating dental and/or maxillofacial deformities. Among the patients studied, a prevalent pattern emerged, revealing that severe anomalies such as micrognathia (56 %), high-arched palate (29 %), cleft palate (40 %), limited mouth opening (31 %), and dental anomalies (28 %) were frequently observed. Importantly, many of these patients were found to have more than one of these anomalies. Even though these maxillofacial impairments are known to be associated with dental problems (e.g., cleft palate is associated with oligodontia, hypodontia, and malocclusion), their secondary effects on the dental phenotype were not reported in the studies. CONCLUSION Our findings have uncovered a notable deficiency in existing literature concerning dental and maxillofacial manifestations in AMC. This underscores the need for interdisciplinary collaboration and the undertaking of extensive prospective cohort studies focused on AMC. These studies should assess the oral and maxillofacial abnormalities that can impact daily functioning and overall quality of life.

Abstract
INTRODUCTION Temporomandibular Joint (TMJ) reankylosis is one of TMJ arthroplasty complications that can interfere masticatory function and aesthetics. This case report aimed to describe a TMJ reankylosis in growing age patient that occurred 5 years after interpositional arthroplasty using gold foil. Interpositional arthroplasty using temporalis fascia and costochondral graft followed by unilateral coronoidectomy could be a treatment option. CASE PRESENTATION A 17-year-old female came with inability to open her mouth 5 years after first interpositional arthroplasty using gold foil due to traumatic TMJ ankylosis. Patient was diagnosed type IV left TMJ reankylosis with left coronoid process hyperplasia. Patient was treated with interpositional arthroplasty using temporalis fascia as an interposition material for articular disc substitution, costochondral graft for ramus condyle unit (RCU) reconstruction and followed by unilateral coronoidectomy. Postoperative mouth opening was ±26 mm. One year evaluation showed stable mouth opening and no recurrency occured. DISCUSSION Age at growing period, insufficient gap width, surgical technique and the effects of previous surgery may generate TMJ reankylosis. Temporalis fascia widely used for interposision material and act as a lubricant that makes movement frictionless. Costochondral graft can be used for RCU reconstruction to prevent decreasing mandibular ramus height and openbite. CONCLUSION Growing age increases the risk of TMJ reankylosis. Interpositional arthroplasty, which used temporalis fascia and a costochondral graft, has resulted in a sufficient mouth opening and an improvement in masticatory function. Recurrence was not found in the 1-year postoperative evaluation.

Abstract
Coronoid process hyperplasia (CPH) is an oral and maxillofacial surgical disease that can result in restricted jaw movement due to an enlarged and elongated mandibular coronoid process. It is characterized by the painless progressive restriction of unilaterally or bilaterally mouth opening. Clinically, unexplained bilateral CPH is less common and therefore often overlooked or misdiagnosed, and coronoidectomy can be very effective on improving mouth opening. Currently, the exact etiology and mechanism of congenital CPH have not yet been fully understood, but it is generally believed to be genetically related. In this paper, the relationship of the congenital mandibular CPH with the related diseases was examined based on cases collected in our clinic and literature review for the clinical diagnosis and treatment of patients with restricted mouth opening associated with CPH.

Abstract
OBJECTIVE Coronoid process hyperplasia (CPH) of the mandible can lead to restricted mouth opening and maxillofacial deformities, which have been hypothesized to be closely associated with genetics. This study investigated the relationship between congenital CPH and TGFB3 mutation in a family of patients with CPH. STUDY DESIGN A limited mouth opening proband with CPH underwent whole-exome gene sequencing in November 2019, and the results confirmed compound heterozygous mutations in the TGFB3 gene. Subsequently, clinical imaging and genetic testing were performed on 10 other individuals in his family. RESULTS A total of 9 people in this family have CPH. Among them, 6 have the same exon compound heterozygous mutation sites of the TGFB3 gene (chr14-76446905 and chr14-76429713), accompanied by homozygous or heterozygous mutations in the 3'untranslated region (3'UTR) of the TGFB3 gene (chr14:76429555). The other 3 individuals have a homozygous mutation in the 3'untranslated region of the TGFB3 gene. CONCLUSION The heterogeneous compound mutation of the TGFB3 gene or the homozygous mutation of 3'UTR of the TGFB3 gene may be correlated with CPH. In addition, the specifically related mechanism needs to be confirmed by further genetic animal experiments.

Abstract
An estimated 8 to 15% of women, and 3 to 10% of men currently suffer from Temporomandibular disorders, and it has been reported that sounds are a common finding and have been observed in 28% to 50% of the adult population; sounds are almost always connected to "internal derangements" a condition in which the articular disk displaced from its position on the mandibular condyle. Due to the multifactorial etiology of temporomandibular joint dysfunction, any accurate diagnosis based on clinical examination alone often proves to be difficult, so a clinical examination should be utilized together with other imaging methods to determine the relationship between the disk and condyle before and after treatment. In general, management of temporomandibular joint-related conditions is necessary when pain or dysfunction is present, so many surgical or nonsurgical methods of treatment have been reported. The Occlusal splint is 1 of the most widespread treatment it induces a slight vertical condylar distraction and eliminates the occlusal factor, which can be responsible for Temporomandibular joint disturbances, removing the influence of the teeth on the joint position by the slight distraction of the joint which, in turn, enables damaged connective tissue to heal.

Abstract
Superolateral dislocation of the condyle is a rare mandibular fracture. The treatment goal is to return the dislocated condyle to its original position to recover normal function. This study reports on superolateral dislocation of the condyle with mandibular body fracture. The mandibular body was completely separated, and the medial pole of the condyle head was fractured. The condyle segment was unstable and easily dislocated after reduction. The temporalis muscle on the condyle segment might have affected the dislocation of the condyle. A coronoidectomy was performed to disrupt the function of the temporalis muscle on the condyle segment in order to successfully reduce the dislocated condyle. Coronoidectomy is a simple procedure with minimal complications. We successfully performed a coronoidectomy to reduce the superolateral displaced condyle to its original position to achieve normal function. Coronoidectomy can be effectively used for reduction of superolaterally displaced condyles combined with severe maxilla-mandibular fractures.

Abstract
Coronoid process hypertrophy (CPH) consists of an abnormal volumetric increment of the mandibular coronoid process; as this process grows gradually, the infratemporal space needed for the rotation and translation of the mandible is reduced, which results in a reduction of the range of mouth opening and lateral excursion, limiting mouth opening. The purpose of this case report was to describe a rare case of hypertrophy of coronoid processes with associated temporomandibular ankylosis, monitored for over 20 years. The patient was first visited when he had a facial trauma at the age of 4. Then he was followed through clinical, functional, instrumental, bi-dimensional and three-dimensional radiological evaluations up to the age of 24. Physical therapy was initiated at the age of 10 to improve the condition of the masticatory muscles, while at the age of 14, Transcutaneous Electrical Nerve Stimulations were performed to reduce muscle tension and, a bite plane was delivered to control the parafunctional activity of the jaw in the night and self-control instruction was provided for daytime habits. The adult patient has not accepted surgical intervention; thus, the future objective is to continue monitoring over the years to avoid a detrimental progression of the medical condition through physical and functional therapies while waiting for patient consent to surgery if needed.
