Study design: Retrospective case series. Objective: Alloplastic temporomandibular joint replacement has been established as a standard technique for end- stage temporomandibular (TMJ) pathologies. Joint replacement when there are extensive mandibular defects remains a challenging clinical problem. Custom-made extended temporomandibular joint replacement is a feasible option but there is limited information about this emerging technique. Methods: Included were all patients undergoing extended TMJ-replacements (TMJe), all operatrions were carried out by the senior author. Surgical technique was either single stage or two stage protocol. Surgical details and pitfalls and outcome of more than 2 years follow-up with reference to thirteen including twelve patients were recorded. Results: The most common diagnosis was ameloblastoma of the mandibular ramus. Single stage or two stagge regime were carried out depending on resection requirements and involvement of teeth. Improved mouth opening of more than 30mm was achieved in 10 of 12 patients. One patient with previous TMJ replacement reported temporary weakness of the facial nerve, which resolved after 10 months. Conclusions: The authors suggest a simplified anatomically based single-stage or two-stage regime, with both regimes achieved excellent anatomic reconstruction, facial appearance and function with low surgical morbidity. Custom-made extended temporomandibular joint protheses appear an advanced and reliable solution for reconstruction of combined complex mandibular defects including the temporomandibular joint. If surgical clearance of the pathology can be achieved, a single-stage regime is favoured., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Ablative surgery of the mandibular condyle poses a unique reconstructive challenge for many reasons. The condyle and it's relationship to the TMJ is a unique, complex, functional and aesthetically relevant piece of human anatomy. Resection may be required for both malignant and benign pathologies; each posing a differing set of surgical variables. Particularly in neoplastic processes, there must remain a certain degree of peri-operative flexibility with regards to the extent of the resection, and forethought to the requirement for post-operative radiotherapy; both of which further complicate choice of reconstructive option and surgical or prosthetic planning. The cases involved can often concern paediatric patients, and an additional aspect to be considered is that of growth potential. In this piece, we will discuss the indications for ablation and the techniques involved. We will elaborate on the reconstructive challenges specific to reconstructing the condyle in post-ablative cases. We will then describe and analyse the established reconstructive techniques; aiming to provide a balanced view on the advantages and disadvantages. Our focus will include autologous options such as vascularised and non-vascularised free tissue transfer, and the non-autologous options of custom and stock implants. We will also touch on distraction osteogenesis and ramus osteotomies. Lastly we will look to the future and consider possible innovative techniques which may become available to the surgeon., (© 2022 Craniofacial Research Foundation. Published by Elsevier B.V.

Although condylar dislocation is not uncommon, terminology, diagnostics, and treatment concepts vary considerably worldwide. This study aims to present a consensus recommendation based on systematically reviewed literature and approved by the European Society of TMJ Surgeons (ESTMJS). Based on the template of the evidence-based German guideline (register # 007-063) the ESTMJS members voted on 30 draft recommendations regarding terminology, diagnostics, and treatment initially via a blinded modified Delphi procedure. After unblinding, a discussion and voting followed, using a structured consensus process in 2019. An independent moderator documented and evaluated voting results and alterations from the original draft. Although the results of the preliminary voting were very heterogenous and differed significantly from the German S3 guideline ( p < 0.0005), a strong consensus was achieved in the final voting on terminology, diagnostics, and treatment. In this voting, multiple alterations, including adding and discarding recommendations, led to 24 final recommendations on assessment and management of TMJ dislocation. To our knowledge, the ESTMJS condylar dislocation recommendations are the first both evidence and consensus-based international recommendations in the field of TMJ surgery. We recommend they form the basis for clinical practice guidelines for the management of dislocations of the mandibular condyle.

Kimura's disease is a rare disease of unknown aetiology, commonly presenting with slow-growing head and neck subcutaneous nodules, lymphadenopathy, eosinophilia and elevated immunoglobulin E. This report describes a very rare case of a 41-year-old female, of White-British ethnicity, with a new diagnosis of Kimura's disease of the parotid gland and associated cutaneous features. The patient was investigated for 3 years before a diagnosis of Kimura's disease was reached. A superficial parotidectomy was undertaken and no recurrence was observed in the 20 months following surgery. Kimura's disease is easily misdiagnosed, owing to lack of clinical awareness. This case report highlights the troubling symptomatology as well as complexities of diagnosis and management of Kimura's disease. A high level of clinical suspicion is required, for patients of any ethnicity and sex presenting with features consistent with the disease, in order for prompt diagnosis, investigation and management to be achieved.

Ohnishi in 1975 first described temporomandibular joint (TMJ) arthroscopy. Along with its extensive use, a range of complications has emerged. We describe a patient who experienced parapharyngeal swelling after undergoing arthroscopy. Prolonged intubation up to 1 hour postoperatively was required. The swelling resolved completely over 6 h without further intervention.

Introduction: Difficulties with the correct diagnosis and treatment of nodular fasciitis in head and neck region has been reported in the literature. Nodular fasciitis was mistaken for sarcoma, papillary thyroid carcinoma, Burkitt's lymphoma, pleomorphic adenoma, or as a vascular lesion., Presentation of Case: We present a patient with a single node in the neck with accelerated growth, which clinically appeared as a malignant epithelial tumor with unknown primary. The en bloc removal of the tumor and selective neck dissection was performed with bilateral tonsillectomy and biopsy of the tongue base. The histopathology revealed the tumor to be nodular fasciitis. No malignant cells were detected., Discussion: Due to very rapid growth, its rich cellularity and high mitotic activity, nodular fasciitis can be mistaken as a malignant tumor. Trauma and/or infection is advocated to be a trigger for the formation of nodular fasciitis, although the exact aetiopathogenesis still remains unknown. Our patient admitted to regularly practicing martial arts with his opponent performing a specific combat maneuver applying pressure into the neck and submental region, which might have triggered the formation of the nodular fasciitis., Conclusion: Nodular fasciitis is a benign and often overlooked diagnosis in the head and neck region, that can be misinterpreted as a malignant tumor both clinically and histologically. A comprehensive medical history may help to avoid unnecessary radical treatment. If a malignancy cannot be confidently ruled out, the en bloc resection of the tumor with selective neck dissection may offer a safe option with low morbidity., (Copyright © 2012 Surgical Associates Ltd.

Background: We present the case of a fractured mandible due to a dog bite in a 9 month old female. Dog bites in this age group are rare as are fractured mandibles. There are only two reported cases of fractured mandibles due to dog bites in the literature. This is the youngest. The other reported cases were in a 1 year old and also in a 4 year old., Case Presentation: A 9 month old female was brought by her parents to the Emergency Department after sustaining a dog bit to the face. This was assessed by the emergency physicians and deemed to be superficial. The patients wounds were irrigated, and she was given oral antibiotics. She was transferred to our department were she was assessed under anaesthetic. A fracture of her mandible was discovered and treated with open reduction and internal fixation., Conclusion: The case presentation highlights the important of proper assessment of facial lacerations for not only neurovascular status and the parotid duct, but also the hard tissues. The case also highlights the difficulty of treating children and infants with fractures of the mandible and the importance of follow-up to monitor growth.

A case of a father who treated his child's facial laceration with the home supply of "superglue" having been previously misinformed that superglue is used to treat lacerations is presented. The differences between tissue adhesive and superglue are described and suggest that emergency staff should be careful to avoid using the term "superglue" when using tissue adhesives.
