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.
鼻腔和鼻窦发生的施万瘤是罕见的病变，世界文献中仅有散发病例报道。该病变最常发生于筛窦和上颌窦，蝶窦有两例报道。尚无额窦施万瘤的病例报道。本文介绍了4例说明性病例以展示其临床特征。放射学检查应包括平片、前后位和侧位体层摄影。计算机断层扫描在手术规划中似乎很有用。本文提出了一种手术方法，强调在保留相邻结构并修复任何由此产生的硬脑膜缺损的情况下，细致、完整地切除病变。
