Comparative study between tubotympanic and atticoantral types of chronic suppurative otitis media.

This prospective study was done to compare the different aspects of tubotympanic (group I) and atticoantral types (group II) of chronic suppurative otitis media. The study included 200 patients of chronic suppurative otitis media, of them 100 were of tubotympanic type and 100 were with atticoantral disease. The age (mean +/- SD) of group I and II were 17 +/- 2.7 years and 12 +/- 2.3 years respectively (P < 0.05). The majority of the patients having poor socio-economic condition 69% in group I and 87% in-group II. In both groups, slum dwellers with bathing habit in pond or river and illiterate were more sufferer (P < 0.05). There was central perforation in all patients in-group I, and in-group II, 67% were with attic and 33% were with marginal perforations. In group I, aural discharge was mucoid or mucopurulent in majority of cases 80% and in-group II foul smelling scanty ear discharge was from 88% of subjects. In atticoantral type, hearing impairment was more than tubotympanic disease. Complications were more in atticoantral type of disease. In-group II, post auricular sinus 25% was the commonest extracranial complication followed by subperiosteal abscess 18%, and meningitis 10% was the commonest intracranial complication followed by brain abscess 8%. In tubotympanic type conservative treatment with reconstructive surgery were the treatment of choice, whereas radical or some modifications of radical surgery (with or without reconstruction) were the treatment plan for atticoantral disease. Among the groups the mortality rate was only 4% in-group II and was due to intracranial complications. The study recommends early detection and effective surgical treatment of the disease to improve the situation.
