Abstract
Schwannoma is a benign, slowly growing nerve sheath tumor which can arise from any peripheral nerve containing schwann cels. cells. They do not give rise to schwannomas in the head and neck area. Therefore, it is generaly known that schwannomas seldom occur in the nasal cavity ocupied by the olfactory nerve. We have experienced a tumor that developed in the uper nasal cavity including the olfactory cleft and ethmoid sinus. Based on the location of tumor development, we initialy diagnosed it as an olfactory removed through craniofacial resection. We herein report a case of an olfactory schwanoma with a brief review of the literature in order to alert other clinicians to this rare tumor to expedite apropriate management.
