PURPOSE: Arthroscopic lysis and lavage surgery (AS) is an effective modality that can decrease pain and increase maximum interincisal opening (MIO) in patients with internal derangement (ID) of the temporomandibular joint (TMJ). However, some patients remain in pain or have limited mandibular range of motion despite AS. The purpose of this study was to determine the effectiveness, prevalence of adverse effects, and predictors of response to TMJ AS in patients with TMJ arthralgia and ID...

Nodular tenosynovitis usually affects the hands and it represents a benign pathology with locally aggressive behavior. Its etiology could be related to chronic inflammatory processes such as trauma, metabolic disturbance, and joint diseases. Histopathological analysis is required for a diagnosis of certainty and surgery represents the treatment of choice. There are no cases in the literature that describe a nodular tenosynovitis affecting the temporomandibular joint (TMJ) The main aim of the present report therefore, is to describe this unusual case and to show the utility of arthroscopic procedures in managing intra-articular tumors of the TMJ...

Background: HFM patients' reconstruction has always been a challenge for maxillofacial surgeons, and numerous reconstructive techniques have been described. Surgical treatment depends on the patient's age and contemplates Temporomandibular Joint (TMJ) reconstruction in conjunction with orthognathic surgery, usually necessary following completion of growth to maximize the functional and esthetic results. Distraction osteogenesis had gained popularity as valid alternative in growing patients, but the two primary methods to reconstruct the TMJs involve the use of autogenous, using free or microvascular bone grafts, or alloplastic graft, but there is no widely accepted method...

OBJECTIVES: Patients suffering from osteoarthritis, ankylosis (e.g. post-trauma or tumour) in the temporomandibular joint (TMJ) can present with symptoms such as severely restricted mouth opening, pain or other dynamic restrictions of the mandible. To alleviate the symptoms, a total joint prosthesis can be indicated, such as the Groningen TMJ prosthesis. This was developed as a stock device with a lowered centre of rotation for improved translational and opening capacity. This study aimed to improve the design of the prosthesis, and produce a workflow for a customized Groningen TMJ prosthesis, in order to make it more accurate and predictable...

Malavika Subu, Jun-Young Paeng
Reduction malarplasty is one of the most commonly performed cosmetic and plastic surgery in Asian countries. Bony ankylosis of the temporomandibular joint (TMJ) occurs usually as a result of trauma, infection, failed surgeries, and autoimmune diseases. Reduction malarplasty has low incidence of TMJ-related complications. A 33-year-old female patient came with complaint of restricted mouth opening around 18 mm, which was developed immediately after the reduction malarplasty 2 years before. On computed tomography image, bony adhesion and the defect from the surgical drilling were found around right TMJ...

INTRODUCTION: The role of temporomandibular joint (TMJ) surgery is not well defined due to a lack of quality randomized controlled clinical trials, comparing different TMJ surgical treatments with medical and placebo interventions. The temporomandibular joint interposal study (TEMPOJIMS) is a rigorous preclinical trial divided in 2 phases. In phase 1 the authors investigated the role of the TMJ disc and in phase 2 the authors evaluated 3 different interposal materials. The present work of TEMPOJIMS - phase 1, aims to evaluate histopathologic and imaging changes of bilateral discectomy and discopexy in Black Merino sheep TMJ, using a high-quality trial following the ARRIVE guidelines...
