Schwannoma of the nose and paranasal sinuses

Schwannoma is a benign tumor arising from the Schwann cells of nerve sheath. Though they arise more commonly in the head and neck than other regions, a thorough search in the literature including medline revealed only about 47 reported cases of schwannoma in the paranasal sinuses of which the maxillary sinus involvement is more common. We report three cases of schwannoma arising from unusual sites in the paranasal sinuses with different modes of presentation, each requiring a specific approach for surgical excision Transnasal endoscopic approach in combination with conventional approaches is of immense value in the surgical management of these benign lesions of the paranasal sinuses.
