A technical modification of Yang's level III TMJ arthroscopy: a simplified disc suturing approach

Temporomandibular joint (TMJ) internal derangements with anterior disc displacement without reduction can be treated arthroscopically. However, traditional arthroscopic disc repositioning and suturing techniques are technically demanding and associated with a steep learning curve. This technical note describes a modification of Yang's level III TMJ arthroscopy in which the suture passage is performed using a single access point through the cartilage of the external auditory canal, avoiding the need for a fourth portal. The modification aims to simplify the operative sequence by reducing the number of access points required for suture management.
