A Study of the Clinicopathologic Behaviour of the Different Types of Unsafe Chronic Otitis Media

A Cross Sectional Study of Clinicopathologic Behaviour of Primary, Secondary and Mixed Types of Atticoantral Chronic Otitis Media

The purpose of the study is to study the clinicopathologic behaviour of the 3 dangerous types of chronic otitis media that are prone for complications. In which type are the complications more common? Which type gives rise to more hearing loss? How does the disease process in the 3 types evolve? should the 3 types of otitis media be managed differently?
