Novel Surgery Approaches in Laryngopharyngeal Schwannomas: A Retrospective Analysis.

Purpose: Laryngeal schwannoma is a rare condition with limited research. This case series presents cases of laryngeal schwannoma in our department with details on the surgical approaches and prognosis of patients, in order to add more evidence for this setting.

Methods: The patients presented with symptoms that suggested diseases in the throat. These patients were examined by laryngoscopy, magnetic resonance imaging (MRI), and computed tomography (CT). Depending on the tumor size and location, trans-oral endoscopic (laser-assisted) resection, or open laryngeal surgery was applied. The open surgery was modified by splitting the thyroid cartilage plate in the middle (not entering the larynx) and separating the inner surface of the thyroid cartilage plate on the affected side.

Results: The tumors of all patients were successfully removed. Then, these patients were followed up at the 1st, 3rd, and 6th month after surgery through clinic visits. Laryngoscopy, MRI, and CT were performed to examine the patients, and no recurrences were detected.

Conclusion: The changes applied for the procedure presented in the present study have the potential to reduce recovery time and scarring, and help preserve throat function. The investigators consider these as potential alternatives to existing methods for treating laryngeal schwannomas. However, more research is required to refine the methods used to treat schwannomas and to ensure that patients receive the best care.
