Abstract

Primary tumors of the parapharyngeal space are rare and account for only 0.5% of head and neck neoplasm. About 80% of parapharyngeal tumors are benign and 20% are malignant. Parapharyngeal space is classified into the Prestyloid space and the Poststyloid space. The Poststyloid tumors are usually benign lesions such as neurogenic tumors, paragangliomas, vascular tumors, or aneurisms. The origins of prestyloid tumors are much more diverse pathology, the pleomorphic adenoma in parotid deep lobe is most common type. Several surgical approaches have been introduced for management of parapharyngeal tumor, such as transcervical, transparotid-transcervical and the transcervical-transmandibular approaches. This paper is aimed to present a large parapharyngeal space tumor removed via transoral approach. It is possible to remove easier by using microdebrider. The pathologic diagnosis was pleomorphic adenoma.
