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.
