Esophageal dysfunction in patients with contact ulcer of the larynx

Vocal abuse is the best-known etiological factor in contact ulcer. Other factors, such as hiatus hernia and gastroesophageal reflux have been discussed. A 12-year study of 58 male patients (mean age 52 years) with present or previous contact ulcers, is reported. Forty-three patients were investigated with esophageal function tests, ie, esophageal manometry including pH monitoring, acid-perfusion test, and acid-clearing test. Esophageal dysfunction was found in 74% which is significantly higher than the 30% found in the general population.
