Schwannoma of the larynx. An infrequent laryngeal tumour.

Schwannomas are benign tumours, rare among tumours of the larynx. They normally present as supraglottic masses (because they may arise from the internal branch of the superior laryngeal nerve), most commonly involving aryepiglottic folds or false vocal folds. Most patients present with a globus sensation, dysphagia or hoarseness. Conservative surgery is the treatment of choice. We report a case of a laryngeal asymptomatic neuroma that was diagnosed accidentally in an imaging test. Complete excision of the tumour was performed through a transoral CO₂ laser microsurgery without resorting to a tracheotomy. We discuss the clinical, pathologic and imaging findings and the management of this neoplasm. We also try to update the knowledge on the management of these tumours.
