Abstract

Purpose: This study evaluated the efficacy of surgical arthroscopy in the management of patients with temporomandibular joint chronic closed lock. Patients and Methods: Fifteen TMJs (Twelve patients) suffering anterior disc displacement without reduction and chronic closed lock were enrolled in the study. Arthroscopic lysis and lavage of the superior joint compartment was done under general anesthesia for all patients. Results: The results showed significant resolution of clinical signs and symptoms of TMJ chronic closed lock (pain and tenderness) and full restoration of normal range of motion (maximum interincisal opening, lateral excursions and protrusive movements) and regain of chewing ability. Conclusion: Temporomandibular joint surgical arthroscopy is an effective and minimally invasive modality in treatment of TMJ closed lock.
