Management of paranasal sinus schwannomas.


Schwannomas arising in the nasal cavities and paranasal sinuses are rare entities, with only sporadic cases appearing in the world literature. The lesion most commonly arises in the ethmoid and maxillary sinuses, with two cases having been reported in the sphenoid sinus. There are no reported cases of frontal sinus schwannoma. Four illustrative cases are presented which demonstrate the clinical features. The radiological investigation should include plain films and anteroposterior and lateral polytomography. Computerized tomography appears to be useful in planning surgery. An operative approach is approach is proposed which emphasizes a meticulous and complete removal of the lesion with preservation of adjacent structures and repair of any resultant dural defect.
