Abstract
Objectives: Nasal cavity schwannomas are exceedingly rare, benign neoplasms that pose challenges in clinical differentiation from other nasal tumors. Methods: This study presents 5 cases of nasal cavity schwannoma treated surgically over a 10 year period, along with a review of the literature. Results: The most prevalent symptoms included unilateral nasal obstruction and intermittent nosebleeds. Tumors originated from various nasal sites, including the septum, middle conchae, lateral nasal wall, and alar mucosa. All surgeries were conducted transnasally, with 3 tumors excised en bloc, and the remaining two subjected to piecemeal resection. Ancient schwannoma was identified in 4 cases. No instances of recurrence were observed during the average 61 month follow-up period. Conclusions: The definitive diagnosis of schwannomas necessitates histopathological examination. An endoscopic approach to the nasal cavity, obviating the need for external intervention, proved highly effective and appropriate for both diagnosis and symptom alleviation.
