Abstract

PurposeThe aim of this report is to define a modification of the arthroscopic anterior myotomy that avoids disc suturing procedures for the treatment of advanced internal derangement (I D) of the temporomandibular joint (TMJ). Surgical techniqueThe minimally invasive arthroscopic anterior myotomy (MIAAM) is based on a partial resection of the superior belly of the lateral pterygoid muscle performed through a small incision of the articular capsule associated with a scarification of the posterior ligament of the TMJ. The high-frequency wave system, called Coblation, is extremely useful to be able to complete the MIAAM. ConclusionThis technique is indicated for patients with ID and Wilkes stages III–IV without response to conservative treatments, and the presence of an integral disc with an appropriate consistency is transcendent for the success of the procedure. Because of the unique characteristics of the MIAAM, it can be considered as an alternative to arthroscopic discopexy procedures.
