Modified Temporalis Myofascial Flap for Management of Temporomandibular Joint Ankylosis: JAIN Technique.

Background: One of the management modalities of temporomandibular joint ankylosis is interpositional gap arthroplasty. The most commonly used interpositioning material is temporalis myofascial flap owing to its close proximity to operating site. However, sometimes this flap becomes insufficient in terms of length. Hence, we propose a technique of temporalis myofascial flap lengthening. Technique: The technique described in the manuscript increases the length of the flap by 1½-fold. This increases the reach of the flap till the medial aspect of the created gap avoiding bone-to-bone contact during movement of the jaw.
Conclusion: This technique can be easily and effectively used to ensure proper interpositioning during management of temporomandibular joint ankylosis to avoid recurrence. © The Association of Oral and Maxillofacial Surgeons of India 2020.
