Abstract
This paper reports a case of a large parapharyngeal tumor which caused neuralgic pain in the mandibular nerve region and was removed through a trans-cervical approach combined with lateral mandibulotomy. A 42-year-old woman was referred to our hospital complaining of shooting pain around the right temporal and mandibular region. On computed tomography and magnetic resonance images, a mass measuring 39mm×38mm×31mm was found in the right parapharyngeal space, which reached to the skull base. Under general anesthesia with naso-tracheal intubation, surgical removal of the parapharyngeal tumor was carried out through a trans-cervical approach with lateral mandibulotomy. The tumor was clearly surrounded by a capsule and was connected with the right inferior alveolar nerve. Histopathological diagnosis was schwannoma. The post-surgical course was uneventful except for right mandibular nerve palsy as a sequela. There has been no sign of recurrence during follow-up as of five years after surgery.
