Double mandibular osteotomy with segmental mandibular swing approach to parapharyngeal space.

Surgical removal of benign tumors of the Parapharyngeal space (PPS) is the treatment of choice. PPS tumors may remain undetected for long periods of time and large tumors in the PPS can extend into the Retropharyngeal Space or into the Infra-Temporal Fossa. Anatomically, the mandible represents a significant obstacle to successful PPS surgery.
