Laryngeal schwannoma: A case report and literature review

Abstract

Laryngeal schwannomas are rare benign neurogenic tumors of the larynx. They cannot be detected in the early stages because disease onset is asymptomatic. This case of laryngeal schwannoma provided a reference for clinical diagnosis and treatment strategy. A 24-year-old man presented with a 3-year history of hoarseness and sore throat for 6 months. Laryngoscopy and computed tomography showed submucosal bulging of the right ventricular fold in the right paraglottic space. The patient underwent tracheotomy first, followed by laryngotomy. The edema of the laryngeal mucosa was significantly alleviated, with normal movement of the bilateral vocal cords on the 10th day after surgery. The tracheal tube was removed at the time of discharge. The hoarseness had disappeared at the end of the first month after surgery. The effective treatment of laryngeal schwannoma involves complete resection with surgery while protecting the integrity of the larynx and restoring laryngeal function. The indication for surgery should be strictly controlled to avoid damage to the mucosa and structures of the larynx.

A Review of Microsurgical Resection of Recurrent Laryngeal Neurilemmoma Under Nerve Monitoring

“…Computed tomography and/or magnetic resonance imaging can provide the size and extend of the tumor, but the diagnosis of neurilemmoma can only be confirmed with histopathology 6,7. Surgical resection is the only standard treatment of neurilemmoma, and many different surgical approaches have been described previously 8–10.…”

Pediatric laryngeal schwannoma: a case report

“…Of note, histopathology is still the gold standard in diagnosis. As laryngeal schwannomas are not sensitive to radiotherapy or chemotherapy, the only effective treatment is surgical resection [ 9 ]. The aim of this report is to present and document the clinical presentation, diagnostic approach, and management for such a rare tumor.…”
