Abstract
Schwannoma is the most frequent neoplasma of the parapharyngeal space. Schwannomas are generally benign and slow-growing tumors. They usually do not affect their nerve of origin, however, some cases have paralysis of cranial nerves. The parapharyngeal space is an area with complex anatomic relationships, so it is difficult to remove tumors with nerve preservation from this area. Currently, MRI provides the most useful preoperative information about the appearance and the extent of the tumor in addition to its relationship to surrounding structures. Using MRI, we must carefully determine the best surgical approach to the parapharyngeal space. We should also adequately explain to the patient the high complication rate including damage to the cranial nerve.
