Abstract

Parapharyngeal space (PPS) tumors are rare and constitute less than 1% of all head and neck neoplasms. Benign and malignant tumors can arise from various structures of the parapharyngeal space. The PPS is a space deep in the neck, shaped like an inverted pyramid. The parapharyngeal space is bounded medially by the pharyngeal wall, laterally by the deep sheet of the parotid fascia, dorsally by the deep cervical fascia and cervical vertebrae and above by the base of the skull. Parapharyngeal space masses are most commonly benign (80%), salivary gland tumors are mostly pleomorphic adenomas that typically occur in the pre-styloidal space, whereas the schwannomas, which are also found more frequently, arise in the post-styloidal space. Treatment planning for parapharyngeal space tumors requires a good understanding of anatomy and careful evaluation of imaging findings. Management of parapharyngeal tumors is a challenge because of the complex anatomy of the space and the various pathologies encountered. Treatment is generally surgical resection, especially in benign tumors, with various approaches, can be trans-oral, trans parotid, transcervical. Surgeons should choose a surgical approach that can facilitate complete tumor extirpation with minimal morbidity. This article will describe the anatomy, diagnosis, and management of PPS tumors using a trans parotid approach.
