Clinical features of newly presenting cases of chronic otitis media

The clinical features of 58 consecutive patients presenting with a new case of chronic otitis media were prospectively collected over a 15-month period. Twenty-three ears had a keratin filled marginal or attic defect (14 with cholesteatoma), 20 had a self-clearing marginal or attic defect, and 21 had a central tympanic membrane perforation (including one cholesteatoma). Twenty patients (35 per cent) had an abnormal finding in the opposite ear. The patients' ages were dispersed over a wide range of age groups with a mean age of 34 years. Hearing loss was the most common presenting symptom (78 per cent), followed by otorrhoea (64 per cent). A significant proportion of patients denied any history of otorrhoea. Our findings should alert the clinician to suspecting a new case of COM in patients with hearing loss of any age, with, or without, a history of otorrhoea, regardless of their background ear history or the duration of their symptoms.
