Novel technique to prevent or correct open‐mouth deformity after bilateral mandibular resection: Use of tensor fascia lata slings

Abstract

Open-mouth deformity after mandibular resection presents a challenge for surgeons and patients, contributing to significant functional and cosmetic morbidity. We present an innovative surgical technique to prevent or correct open-mouth deformity. Tensor fascia lata slings were utilized in combination with maxillomandibular fixation to surgically correct or prevent open-mouth deformity in four patients who had previously undergone mandibulectomy or at the time of a contralateral mandibulectomy following prior hemimandibulectomy and reconstruction. Two patients achieved favorable outcomes, including oral competence and improved resting jaw position, while open-mouth deformity could not be corrected for one patient. Another patient remains in the early postoperative period following a secondary procedure to correct open-mouth deformity. Openmouth deformity is a functional/aesthetic problem that has not been addressed in the literature. Use of tensor fascia lata slings to suspend the mandible is a novel approach to the surgical management of open-mouth deformity.
