Abstract

BACKGROUND AND OBJECTIVES
Chronic suppurative otitis media (CSOM) is a common infectious disease in childhood of poor hygiene group. In addition, in industrialized countries, with rising popularity of tympanostomy tubes for management of otitis media with effusion, CSOM is a potential problem in any child who had inserted ventilating tubes previously. Hearing loss following CSOM can negatively affect learning, speech, and cognitive function, so effective and timely management of CSOM is mandatory. The surgical procedure may be necessary in some children with CSOM, but when it is performed at a too early age, there might be more chances of recurrence than adults.
SUBJECTS AND METHOD
Used in the study were 51 ears from patients who received tympanomastoidectomy due to CSOM in tertiary referral center from 1995 through 2004. The mean age was 9 years and 6 months. Cholesteatoma was found in 30 cases (58.8%). Age at operation, hearing outcomes, and the surgical results were retrospectively reviewed. RESULTS: Canal wall down mastoidectomy was performed in 23 cases and canal wall up procedure in 28 cases. Revision surgery was performed in 9 cases (17.6%) and mean duration between first and revision surgery was 27 months. In the cases of cholesteatoma, the rate of revision surgery was different between under 6 years old and over 7 years old group (p=.045). The age at 1st operation and postoperative hearing outcome had no correlation.
CONCLUSION
Since the1st operation is performed earlier, the rate of revision may increase, especially in cases of cholesteatoma.
