Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Pterygomaxillary disjunction

Group Type EXPERIMENTAL

Pterygomaxillary disjunction with interposition Y-shape plate

Intervention Type PROCEDURE

All patients will be treated under general anesthesia. The pterygoid plate will be fractured, pried up, and pushed backward. A Y-shape plate will be fixed to the lateral maxillary surface with its vertical limb and the other two limbs are turned to fit into the retro maxillary space preventing the reattachment of the fractured pterygoid plate
