Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • Change in wound healing

    The sutured wounds will be examined after one and two weeks for signs and symptoms of infection including swelling, redness, hotness, pus discharge, and pain in addition to observation for any manifestations of wound healing disturbance, as wound dehiscence and hardware exposure.

    1st week and 2nd week

  • Change in TMJ clinical dysfunction

    Helkimo's dysfunction index is used, including the interincisal opening of the mandible, deviation during the opening, dysfunction of TMJ, pain in the TMJ and preauricular region, and also masticatory muscles were palpated for pain during the follow-up periods.

    1st week, 2nd week, 1 month, and 3 months

  • disc position

    MRI assessment by proton-density (PD), Evaluation by MRI will be done after 3 months to assure disc position.

    at 3 months

Study Arms (1)

Pterygomaxillary disjunction

EXPERIMENTAL
Procedure: Pterygomaxillary disjunction with interposition Y-shape plate

Interventions

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

Pterygomaxillary disjunction
