Abstract

BACKGROUND: Hypocellular squamomastoid is closely related with chronic otitis media. The epidemiologic study of otitis media in adult population is limited in theTaiwanese literature. We try to imply the prevalence of chronic otitis media in children and adolescents at different era from the patients who received brain computed tomography. METHODS: In 2010 and 2011, 12,493 persons, including 6,547 men and 5,946 women, had received brain computed tomography at a regional hospital in North Taiwan. They were averaged of aged 52.8 with SD of 22.3. We reviewed each axial section under bone window (WC 350, WW 2,000). RESULTS: Six hundred and forty-eight persons, including 327 men and 321 women, are enrolled. They are averaged of aged 67.6 with SD of 14.8. The ratios of hypocellular squamomastoid sufferers among those with brain computed tomography decrease as the age level become younger. The incidences are similar between the age level of 20- 29 and 30-39 (0.48% vs 0.95%), which are much less than those of the other age levels (40-49, 3.11%; 50-59, 5.24%; 60-69, 7.93%; and ≥ 70, 8.69%). CONCLUSIONS: We imply that the prevalence of chronic otitis media reduced in Taiwanese children and adolescents as the era progresses, and hence the incidence of the following hypocellular squamomastoid also significantly reduced.
