Introduction
Approximately 25-45% of all schwannomas are found in the head and neck region with the majority originating from the parapharyngeal spaces. Laryngeal schwannoma however is a rare clinical entity accounting for only 0.1% of all benign neoplasms of the larynx. Given the radioresistant nature of schwannomas surgical resection remains the cornerstone of management (1,2). Different surgical approaches are described in the literature depending on tumour size.
Clinical Case
A 70 year old female was referred to the Ear, Nose and Throat clinic for management of a right supraglottic lesion. The patient reported a four to five year history of dysphonia which had had worsened for the past two years along with new intermittent shortness of breath, dysphagia, cough and globus sensation. Flexible nasoendoscopy showed a right supraglottic lesion with intermittent right vocal cord movement. The patient underwent two subsequent transoral CO2 laser debulking procedures one month apart. Histology results showed positive staining for S100, SOX10 and vimentin consistent with a moderately cellular schwannoma. Post operatively recovery was unremarkable with improvement in shortness of breath however persistent dysphonia two months post operatively still present.
Conclusion
This case adds to the growing literature in the management of this rare laryngeal benign neoplasm. The use of transoral CO2 laser resection can be safely applied in appropriate laryngeal schwannoma cases as a minimally invasive intervention. This may reduce risk of infection, damage to surrounding structures and hospital length of stay compared to open surgical approaches.
