Abstract

Spinal and bulbar muscular atrophy (SBMA : Kennedy-Alter-Sung disease) is a rare clinical entity in otolaryngological practice. We report a 52 year-old male with SBMA who underwent total laryngectomy for continuing dysphagia and respiratory problems. Histological examination of the intrinsic laryngeal muscles revealed neurogenic changes mainly in the posterior cricoarytenoid muscle. In this particular case, the selection of total laryngectomy was considered to be appropriate to improve the patient's quality of life (QOL).
