Abstract

Neurilemmoma of the head and neck is not rare in parapharynx, but rare in the larynx. The treatment of choice in neurilemmoma of the larynx is a complete surgical resection. A small size lesion can be removed via an endoscopic approach. For a large size lesion, an external approach, such as the median or lateral thyrotomy, or pharyngotomy, can be more useful. These surgical methods often require preliminary tracheostomy to secure the airway. Through a case of neurilemmoma of the larynx, we present this disease and the treatment course of a patient, who has been successfully treated by surgical excision via trans-cricothyroid membrane approach without tracheostomy. Furthermore, we discuss its symptoms, physical examinations, microscopic features and other options of treatment for laryngeal schwannoma through literature reviews.
