title: An unusual mass filling within the middle meatus.
abstract: Schwannoma is a benign tumor that originates from sheath of myelinated peripheral nerves, rarely seen at the nasal cavity and paranasal sinuses. Symptoms of this tumor are nonspecific, and diagnosis is often made only after histological examination. Schwannoma is radioresistant, and chemotherapy is not effective, so surgical resection is the only curative treatment for this tumor. Endoscopic sinus surgery was the first choice for this case because of its definite origin and being easy to remove for complete excision. We present a patient with schwannoma who underwent an endonasal endoscopic approach for complete resection.
