The article focuses on a study related to the development of a follow-up surveillance protocol in head and neck oncological surgery. It mentions preventing recurrence and identifying patients presenting with recurrent or synchronous disease for improving mortality. It also mentions patients engaged in enhanced follow-up having higher attendance rate with no loss to follow-up and symptomatic patients requesting early follow-up led to the detection of the only recurrence in the cohort.

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.)

Temporomandibular disorders (TMDs) are a prevalent but complex group of conditions that cause orofacial pain. Temporomandibular disorders are recognized as one of the most common chronic pain conditions, alongside back pain and headache disorders. Given the competing theories surrounding what causes TMDs and limited high-equality evidence on optimally treating TMDs, clinicians often encounter challenges in developing an effective management plan for patients. Furthermore, patients will often seek advice from multiple health care providers from varying specialties, seeking curative management, often resulting in inappropriate treatments and no improvement in pain symptoms. Throughout this review, we explore the existing evidence base surrounding the pathophysiology, diagnosis, and management of TMDs. An existing United Kingdom-based multidisciplinary care pathway for the management of TMDs is described herein, highlighting the benefits of a multidisciplinary approach to patient care for TMDs., Competing Interests: Declaration of interest None., (Copyright © 2023 Elsevier Inc.

Objectives: To report clinical outcomes of relapsed oropharyngeal squamous cell carcinoma (OPSCC) after definitive intensity-modulated (chemo)radiotherapy [(C)RT]., Materials and Methods: Data for all relapsed patients treated for OPSCC with definitive (C)RT between 2010 and 2016 were collected. Primary end-point was post-failure survival (PFS)., Results: Overall, 273 OPSCC patients completed definitive (C)RT. Of these, 42 cases (n = 26 human papilloma virus (HPV)-negative; n = 16 HPV-positive) had relapsed (n = 23 persistent disease; n = 19 recurrent disease) and were included in the final analysis. Two-year PFS for the entire population was 30.6%; 20.5% for HPV-negative and 43.8% for HPV-positive patients. Salvage curative surgery was associated with a significantly higher 2 years PFS rate (56.2%) compared with palliative treatment (22.9%) and best supportive care (0%) (p < 0.001). A positive trend in 2 years PFS was recorded in the early complete response cases (49.5%) versus patients who did not achieve a complete response within 3 months of the end of (C)RT (23.0%) (p = 0.11)., Conclusion: A higher PFS rate is achieved when relapsed OPSCC cases are treated with salvage curative intent. HPV-positive disease and early complete response within 3 months from the end of (C)RT may be related to better PFS., (© 2021 Wiley Periodicals LLC.)

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.

Purpose: To assess TNM 8 staging in discriminating overall survival (OS) amongst patients with locally advanced oral cavity squamous cell carcinoma (OCSCC) treated with surgery and post-operative radiotherapy (PORT), compared to TNM 7., Material and Methods: Data from OCSCC patients treated with surgery and PORT between January 2010 and December 2018 were reviewed. Demographics, tumour characteristics and treatment response data were collected, and patients staged according to both TNM 7 and TNM 8. OS and disease free survival (DFS) were estimated using the Kaplan Meier method. Univariate and multivariable analyses were conducted for factors affecting OS, DFS and early disease recurrence within 12 months., Results: Overall 172 patients were analyzed. Median follow up was 32 months for all patients and 48 months for surviving patients. TNM 8 staging demonstrated significant stratification of OS and DFS amongst the entire cohort, whereas TNM 7 staging did not. On multivariable analysis, TNM 8 stage, performance status (PS) and a positive surgical margin were prognostic for OS. Looking at disease recurrence within 12 months, TNM 8 stage IVB, presence of lymphovascular invasion (LVSI), younger age and lesser smoking history were predictive factors on multivariable analysis., Conclusion: TNM 8 is a good development of its predecessor in terms of predicting survival for patients with locally advanced OCSCC. We have also identified younger age (<60 years) and a smoking history of <10 pack years as risk factors for early disease recurrence, potentially representing a separate biological cohort within OCSCC patients., (Copyright © 2021 Elsevier B.V.

Numerous incisions around the ear have been described, and many have been used in oral and maxillofacial surgery for procedures involving the temporomandibular joint (TMJ), condylar neck, and parotid gland, as well as for rhytidectomy. 1-5 Although the traditional preauricular and endaural incisions will frequently provide an excellent outcome, they will heal with a visible scar. 1 , 4 The incision we have described aims to refine the incision to further improve this esthetic outcome. Additionally, surgical procedures around the ear have often resulted in the unpleasant and inconvenient collection of blood or surgical skin preparation in the ear canal. Although not recorded in reported studies, in our experience, patients have commonly complained of "blocked ears" for 1 to 2 weeks in the postoperative period. Although this complication represents minimal risk, it can often be difficult, once clotted or dried, to remove and will be bothersome to the patient. In addition, any packing placed in the external auditory canal (EAC) intraoperatively to mitigate the collection of blood will often and repeatedly dislodge from the EAC, requiring replacement multiple times during the procedure to the frustration of the surgeon. The techniques we have described are 2 straightforward, but innovative, surgical techniques that refine surgery around the ear to improve the esthetics and patient comfort, facilitate the surgical procedure, and increase reliable anatomic access. The modified incision we have described is predominately aimed at operations requiring access to the TMJ, condylar neck, or parotid gland. The techniques were, to the best of our knowledge, first used in our unit at the University of Maryland., (Copyright © 2019 American Association of Oral and Maxillofacial Surgeons.

Introduction: The purpose of this study was to review our recent experience of salvage surgery, comparing larynx and oropharynx recurrence patterns., Methods: A single centre, retrospective review of salvage surgery for recurrent head and neck cancer including patients between 2008 and 2016., Results: 61 patients were identified, 36 underwent salvage laryngectomy and 25 received oropharyngeal resections. The median overall survival of oropharyngeal recurrent tumors was 26 months (95% CI 15-118 months) and for laryngeal tumors was 23 months (95% CI 11-38 months), p = 0.1008. There was a significant overall survival benefit in patients with negative resection margin. The median survival in the negative margin group was 38 months (95% CI 25-108 months) compared to the positive margin group, 9 months (95% CI 5-15 months), p < 0.0001., Conclusion: Survival results following surgical salvage in the larynx and oropharynx appear to be similarly poor. Those patients with clear margins appear to have a significantly better prognosis.

Transoral robotic surgery (TORS) is gaining more widespread use among head and neck surgical procedures. As experience grows with this technique, so do the indications of when and in which patients it can be used. Already established in the treatment of small oral cavity tumours, it is expanding into larger multi-site resections and resections, such as through-and-through-into-the-neck defects, that will require reconstruction. With robot-assisted surgery advancing, so robot-assisted reconstruction (RAR) is evolving. In this paper, we discuss the evolving role of reconstruction in post-TORS defects as well as the role of RAR in today's practice., (© 2018 S. Karger AG, Basel.)

Background: Reconstruction of oral cavity defects requires a thin, pliable flap for optimal functional results. Traditional flap choices are imperfect: the anterolateral thigh flap is excessively thick, whereas the radial forearm flap has a poor donor site. The authors therefore favor calf perforator flaps such as the medial sural artery perforator flap to provide thin tissue with an acceptable donor site. This two-part study aims to demonstrate their suitability for intraoral reconstruction., Methods: In the radiologic part of the study, the authors compared thigh and calf tissue thickness by examining lower limb computed tomographic scans of 100 legs. For their clinical study, they collected data prospectively on 20 cases of oral cavity reconstruction using calf perforator flaps., Results: The mean thickness of the calf tissue envelope was significantly less than that of the thigh (8.4 mm compared with 17 mm) based on computed tomographic analysis. In the clinical study, a medial sural artery perforator was used in the majority of cases (17 of 20). The mean pedicle length was 10.2 cm and the mean time to raise a flap was 85 minutes. There were no flap losses. One patient was returned to the operating room for management of late hematoma and wound dehiscence., Conclusions: Calf perforator flaps provide ideal tissue for intraoral reconstruction and are significantly thinner than anterolateral thigh flaps. In addition to medial sural artery perforator flaps, the authors raised both sural and soleal artery perforator flaps in this series. Opportunistic use of the calf donor site allows the harvest of thin tissue with minimal donor-site morbidity., Clinical Question/level of Evidence: Therapeutic, IV.

This article aims to give an overview on etiology, diagnosis and treatment options of osteonecrosis of the jaw bone among cancer patients receiving anti-resorptive drugs (ARDs). The physiologic bone function of continuous resorption and buildup is modified by the use of ARDs. Although ARDs proved to reduce pain and to improve the quality of life in patients with metastasizing bone disease, side effects such as medication related osteonecrosis of jaw bone (MRONJ) have been frequently reported since ARDs were firstly introduced. The new generation of ARDs such as Denosumab is associated with the same incidence of MRONJ among cancer patients. The etiology of MRONJ is not entirely understood and many hypotheses have been proposed. ARDs can modify the hard tissues directly by accumulation in the bone, or indirectly by suppression of the osteoclasts, inhibition of angiogenesis and vascularity. Some ARDs such as Bisphosphonates have reportedly the capacity to interfere directly and indirectly with the bone physiology. MRONJ can be a debilitating disease with non healing freely exposed bone in the oral cavity in patients, who already suffer from a primary cancerous disease. Knowledge of MRONJ as a potential side effect of ARDs is crucial for health professionals treating patients with bone modulating drugs.
