Temporomandibular joint (TMJ) ankylosis involves fusion of the mandibular condyle to the base of the skull. The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence. The experience of managing one such case is reported in light of a review of the literature on this condition. This report describes a case of a 7-year-old girl with inability to open her mouth, diagnosed with unilateral right bony TMJ ankylosis. Key management principles included adequate removal of the ankylotic mass, gap arthroplasty with interpositional temporalis myofascial grafting and post-operative physiotherapy. The patient maintains a satisfactory maximal incisal opening till the present day. A detailed history, clinical and functional examination, radiographic examination facilitating correct diagnosis followed by immediate surgical intervention, and physiotherapy might be beneficial to restore physical, psychological and emotional health of the child patient with TMJ ankylosis.

Introduction: This study was performed to analyse the oral health-related quality of life (QoL) and masticatory functional efficiency after release of temporomandibular joint (TMJ) ankylosis.
Materials And Methods: There were two groups with Group 1 having 12 operated cases of TMJ ankylosis and Group 2 having 12 normal participants with age- and gender-matched controls. The maximum voluntary bite force (MVBF) of the cases was measured at 3 months, 6 months and 1 year postoperatively with a digital gnathodynamometer.

Objective: This research aims to introduce using antegonial notch angular measurements on lateral cephalometry as a simple low-dose radiographic approach for monitoring mandibular growth in children after TMJA treatment.
Methods: This retrospective cohort study used dental records to identify eligible patients: healthy children with true unilateral TMJA who underwent conservative gap arthroplasty followed by post-operative physiotherapy. The primary outcome was changes in antegonial notch angular measurements over time.

Background: The efficacy of hyaluronic acid (HA) after arthrocentesis in temporomandibular joint (TMJ) disorders is recognized, but the therapeutic effect of different HA doses remains unclear.
Purpose: The study purpose was to measure and compare the therapeutic efficacy of different HA doses among patients with intra-articular pain and dysfunction undergoing arthrocentesis.
Study Design, Setting, Sample: Subjects with intra-articular pain and dysfunction presented to Afyonkarahisar University of Health Sciences between September 2022 and December 2023 were screened for study inclusion.

Temporomandibular joint (TMJ) ankylosis, characterized by osseous-fibrous fusion, severely impairs mandibular function. While alloplastic total joint replacement (TJR) is the gold standard, long-term outcomes remain understudied. The aim of this study is to evaluate the long-term esthetic and functional outcomes of prosthetic replacement and to retrospectively analyze our 20-year experience.
