Contact granuloma
（重定向自Contact ulcer）
Contact granuloma, also known as a contact ulcer, is a condition where an ulcer is found in the vocal folds, on the mucous membrane of the posterior third of the vocal cord (vocal process) where the vocal ligament attaches. The most common cause of the condition is sustained periods of increased pressure on the vocal folds, and is commonly seen in people who use their voice excessively such as singers (John Mayer, for example). Gastroesophageal reflux disease is also thought to be a contributing factor in the development of contact ulcers.
