Illustrated surgical techniques for management of impingements of the temporomandibular joint.

When clinically significant impingements of the temporomandibular joint (TMJ) exist, simple introduction of an arthroscope into the superior compartment can be difficult. Bone mass and volume of lateral fossa, lateral eminence, and tubercle impingements can be too large for micro-arthroscopic shaving rotors to manage efficiently. This paper presents examples of Types I-III impingements with pictorial modifications of open arthroplasty techniques for management.
