Pterygomaxillary Disjunction With Interpositional Y-shape Plate in Patients With Temporomandibular Joint Derangement

Temporomandibular joint internal derangement (TMJ ID) is the most frequent type of temporomandibular disorder (TMDs)which is managed by different therapeutic modalities. it begins with conservative methods like medical treatment, physiotherapy, thermotherapy, and bites appliance therapy. Surgical intervention is a controversial issue in cases not responding to conservative methods. A novel minimally invasive surgical technique which is extracapsular trans oral (Pterygomaxillary disjunction) has been advocated as a minimally invasive extracapsular technique that preserves TMJ integrity.
