Abstract
Objective: To present a new treatment method for internal derangement of the temporomandibular joint.
Patients and Methods: Patients with a clinical diagnosis of internal derangement of the temporomandibular joint, with pain and/or trismus and/or joint noise, underwent pterygoid plate disjunction on the affected side. Severity of symptoms was evaluated before and 18 months after the procedure.
Results: Thirty patients were evaluated. Pain symptoms resolved in 26 of 29 joints and diminished in the remaining 3 joints. Trismus resolved in 22 of 24 patients and diminished in the remaining 2 patients. Joint noise disappeared in 23 of 30 joints.
Conclusions: Pterygomaxillary disjunction appears to be an effective treatment for painful internal derangement of the temporomandibular joint that is worthy of further investigation.
