We describe 2 cases of obstructive sleep apnea syndrome (OSAS) that were found to be caused by the presence of laryngeal masses. Both patients presented with a long-standing history of snoring, gasping for air while sleeping, excessive daytime sleepiness, and morning headaches. In both patients, the lesions were discovered by fiberoptic nasopharyngoscopy. Patient 1, a 46-year-old man, declined surgery, and his lesions (and OSAS) resolved spontaneously in 4 months. Patient 2, a 39-year-old man, did undergo excision of his mass, and he also experienced an alleviation of OSAS.
