Arthroscopic osteoplasty of the medial and anteromedial wall of temporomandibular joint: surgical technique and anatomical considerations.

The anterior displacement of the articular disc is the most frequent cause of pathological alterations in the TMJ. Although it is an extremely common pathology, there is no certainty about the aetiopathogenesis of this disease. The main aim of the present report is to describe new anatomical findings that could help clarifying the aetiopathogenesis of this disease and determine a typology of treatment based on the cause of the disease.

Osteoplasty of Medial Temporomandibular Joint Wall. A New Strategy for Treating Disc Displacement.

Introduction: Numerous factors have been indicated as possible causes of alterations in the articular disc of the temporomandibular joint (TMJ). The main aim of the present study was to demonstrate the effectiveness of arthroscopic osteoplasty of the medial TMJ wall associated with myotomy of the superior head of the lateral pterygoid muscle for treating TMJ internal derangement.

Material And Methods: A retrospective and comparative study was performed analyzing patients diagnosed with TMJ internal derangement and underwent TMJ arthroscopic surgery in our Hospital.
