Abstract
Laryngeal Schwannoma is rare comprising 0.1 – 1.5% of all benign laryngeal tumors. The most common site in larynx is aryepiglottic fold followed by arytenoids, ventricular folds, and vocal cord. Patients present with the symptoms of hoarseness, dysphagia or globus sensation. We present a 33-year-old male with supraglottic schwannoma who experienced hoarseness of voice for three months. The patient underwent micro laryngeal surgery and submucosal solid tumor of false vocal cord was removed. Postoperative recovery was uneventful and after one month of follow up the patient was improving with no hoarseness of voice.
Highlights
Nerve sheath tumors within the larynx are extremely uncommon, with an incidence of 0.5-1.5% of all benign laryngeal tumors.[1]
Laryngeal schwannomas are most commonly located in the aryepiglottic folds in the supraglottis (80%) and 20% of them arise from false or true vocal cords.[6]
Symptoms are related to the mass effect of a slow-growing tumor in the larynx, and include sore throat, odynophagia, dysphagia, stridor, dyspnea, dysphonia, hoarseness, and a foreign body sensation in the throat
Summary
Nerve sheath tumors within the larynx are extremely uncommon, with an incidence of 0.5-1.5% of all benign laryngeal tumors.[1] In larynx these tumors arise in false vocal cord or the aryepiglottic fold. It is a slow growing encapsulated tumor commonly presenting in the fourth and fifth decade of life, especially women.[2] The main symptoms are usually secondary to the mass effect like dysphagia, dysphonia, pharyngeal globus sensation and respiratory distress with inspiratory stridor. We report a supraglottic schwannoma with initial presentation of hoarseness of voice with no significant medical history except for personal habits of smoking and drinking
