[Nasal schwannoma: a report of two cases].

Schwannomas are benign neoplasms arising from Schwann cells of peripheral, cranial and autonomic nerves. Schwannomas of the head and neck comprise 25% to 45% of all schwannomas; however, nasal and paranasal schwannomas account for 4% of these tumors. In this report, two cases of nasal schwannoma are presented. One was a 67-year-old female patient whose tumor completely filled the right nasal cavity and extended beyond the maxillary and ethmoid sinuses. The other patient was a 10-year-old child who had a tumor in the left lateral nasal wall, which is a rare case considering her age. A lateral rhinotomy approach was used in the first patient due to the wide extension of the tumor. In the second case we preferred the intranasal approach because the tumor had limited extension. No recurrences were seen in the postoperative follow-up periods.
