Abstract
Background: To compare clinicopathological characteristics of attico-antral and tubotympanic types of chronic suppurative otitis media .
Methods: In this comparative study 80 patients suffering from otitis media were enrolled. They were divided into group I, with attico-antral disease (perforation in pars flaccid of ear drum) and group II with tubo-tympanic disease (perforation in pars densa of ear drum). Otoscopy and pure tone audiometries were performed in all cases. Examination under microscope were performed, where indicated. Chi square test was applied taking P value of < 0.05 as significant.
Results: Majority (72.5%) were male, with male: female ratio of 2.6:1. Age ranged from 7-35 years, with mean age of 19.47 + 4.38 years. Most of the patients presented in second decade of life. The commonest clinical feature observed in this study was discharging ear in 37 patients (46.25%) and in 25 patients (31.25%) in group I and II respectively which is statistically significant (p=0.021). Mild hearing loss was 28.75% and 21.25% in group I and II respectively which was significantly greater in group I (p=0.004)
Conclusion: There was no significant difference between these two diseases regarding age, gender and socioeconomic status. Clinical features and impaired hearing are significantly common in attico-antral disease as compared to tubotympanic disease.
