Six hundred one patients with vocal fold polyp were treated in our clinic between 1981and 1990. Only two cases were younger than fifteen years of age. The patient ages were most frequent in the forties or fifties. There was no significant difference between the number of male and female patients. Vocal abuse was supposed to be the most frequent cause. Drinking or smoking was not a significant factor in causing the polyp. Surgery was performed in 348 cases; 251 with endolaryngeal microsurgery,90 with laryngeal fiberoscopy and 7 with indirect laryngoscopy. The voice improved in 98% of surgical cases. Fifty nine patients were treated with voice therapy only, and 59% of the patients showed vocal improvement. Voice therapy was most effective for patients with a unilateral small red polyp.
