This study aims to evaluate the efficacy of the ESS technique in correcting TMJ internal derangement, with a focus on functional outcomes and patient satisfaction.

Full description

Background: Internal derangement (ID) of the temporomandibular joint (TMJ) is a prevalent condition characterized by disc displacement, leading to pain, restricted mandibular mobility, and reduced quality of life. While non-surgical treatments are often the first line of management, surgical intervention becomes necessary in refractory cases. Traditional surgical methods, such as arthrocentesis and disc repositioning, have shown variable success rates, particularly in advanced stages of disc damage. This study introduces the Extracapsular Supradiscal Subperiosteal (ESS) surgical procedure, a novel technique designed to address these limitations. Therefore, current study aims to evaluate the efficacy of the ESS technique in correcting TMJ internal derangement, with a focus on functional outcomes and patient satisfaction.

Patients and Methods: A prospective study was conducted on 50 patients (47 females, 3 males; age range: 11-50 years) with TMJ ID refractory to non-surgical management. The ESS procedure was performed to reposition the displaced disc and stabilize retrodiscal tissues without violating the joint capsule. Preoperative and postoperative assessments included pain levels, maximum mouth opening (MMO), and subjective patient feedback.
