Surgical approach to retromandibular parotid tumors.

Because of the anatomy of the deep lobe of the parotid and its restrictive boundaries, retromandibular tumors may be asymptomatic until reaching massive size. Removal by an intraoral approach may be not only disappointing but also disastrous, with disintegration of the tumor and generalized spillage in the wound. Our experience suggests that the best approach to any type of tumor in this region is through the upper lateral cervical tissues with consideration of a mandibular osteotomy if the tumor extends into the retropharynx or the nasopharynx. This review of 12 patients who required osteotomy describes a high success rate with minimal complications.
