Abstract

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.

Resumen

Los schwannomas laríngeos son tumores benignos infrecuentes, localizados generalmente en la región supraglótica. Suelen originarse a partir de la rama interna del nervio laríngeo superior. La mayoría de los pacientes presentan sensación de globo faríngeo, disfagia o disfonía. La cirugía conservadora es el tratamiento de elección. Se presenta un caso de un schwannoma de laringe asintomático, el cual es diagnosticado incidentalmente en una prueba de imagen. La extirpación completa de la lesión se realizó a través de un abordaje endoscópico transoral con láser CO2 sin requerir la realización de una traqueotomía. Revisamos los procedimientos diagnósticos, el diagnóstico diferencial y las opciones terapéuticas de esta infrecuente entidad.
