[Clinical analysis of 15 cases of laryngeal schwannoma]

Objective:To improve the diagnosis and treatment of laryngeal schwannoma. Methods: The clinical data of 15 patients with laryngeal schwannoma were retrospectively analyzed, including 5 male patients and 10 female patients. The tumors were located in aryepiglottic fold in 4 cases, arytenoid region in 4 cases, interarytenoid in 2 cases, false vocal cord in 2 cases, epiglottis in 1 case, vocal cord in 1 case, and subglottic region in 1 case. All patients underwent laryngeal mass resection under general anesthesia, including 4 cases of tumor resection by external approach and 11 cases of tumor resection by oral approach. Results:Following up for 13-80 months, 1 patient had low voice after operation. The hoarseness of 5 patients improved after operation, but not completely recovered. One patient died of esophageal cancer at 49 months of follow-up, and no recurrence was found during the follow-up period. The remaining 8 cases had no obvious abnormalities. Conclusion:The clinical symptoms of laryngeal schwannoma vary, and the prognosis is generally good. The choice of surgical path is closely related to the location and size of the laryngeal schwannoma. If the laryngeal schwannoma is well exposed under endoscopy, the tumor can be removed by transoral radiofrequency coblation. Schwannomas on both sides of the subglottic region can be resected by two surgeries, and the tracheotomy can be performed first if necessary.
