Transmasseteric Anterior Parotid Approach for Treatment of Mandibular Subcondylar Fractures

This study demonstrated the application of transmasseteric anterior parotid approach for open reduction of mandibular subcondylar fractures depending on the basis of the anatomical study of the temporomandibular joint and parotid gland area. The anatomical study was performed on 5 Chinese adult cadavers fixed by 10% formalin. The temporomandibular joints and parotid regions were studied. In the clinical study, 26 patients with mandibular subcondylar fractures were recruited between July 2014 and December 2017. All 26 patients with mandibular subcondylar fractures received satisfactory occlusions and normal mouth opening: no postoperative facial paralysis occurred in these patients. It is crucial to know the anatomy of both temporomandibular joint and parotid region for reducing significantly the surgical trauma and complications. Transmasseteric anterior parotid approach is a feasible approach for the surgical treatment of the mandibular subcondylar fractures. This method can provide adequate exposure, minimal facial nerve injury, open reduction easily, and inconspicuous scarring.
