Sensorineural hearing loss has been described in a small number of patients with ulcerative colitis. At present, it is not known whether this is a rare and sporadic association, or whether these reports represent an under recognised extra-intestinal manifestation of ulcerative colitis. The aim of this study was to determine the prevalence of hearing loss in patients with ulcerative colitis. Twenty patients with active ulcerative colitis (mean age 45 years) were recruited prospectively along with 20 healthy age- and sex-matched controls. Otoscopy, tympanometry and pure tone audiometry were performed. The activity of the disease was scored according to a 12-month cumulative disease activity index. No patients complained of auditory symptoms. Otoscopy and tympanometry were normal in all patients and controls. Pure tone audiometry showed significant sensorineural hearing loss over all frequencies in patients with ulcerative colitis compared with controls. This preliminary study indicates that subclinical sensorineural hearing loss is associated with ulcerative colitis. Further study is warranted to determine the nature of the relationship and its pathological basis.
