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. Open‐mouth 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.
