Mandibular subsigmoid access osteotomy in the management of parapharyngeal space tumors.

Primary parapharyngeal space tumors are rare presentation in the head, face, neck region. Most of these tumors are benign in nature and significantly cast a challenge in terms of diagnosis and their surgical management. Anatomical location of these tumors, either prestyloid or poststyloid, size of the tumor, and proximity to the vital structures determine the appropriate surgical approach. The surgical approach to the parapharyngeal tumors should provide adequate visibility and access for complete removal, preserving the adjacent vital structures and also preventing recurrence. We report our experience in diagnostic workup and management of a series of 18 primary parapharyngeal space tumors with long-term follow-up.
