A Prospective Study of Status of Contralateral Ear in Unilateral Chronic Otitis Media- Based on Otoendoscopy, Audiological, and Radiological Investigations

Abstract

Chronic otitis media is classically defined as an irreversible inflammation of mucoperiosteal 
lining of the middle ear cleft, entirely or in parts. The pathological factors that cause otitis 
media in one ear may also cause it in the other since both ears share the aeration and drainage. 
The fact that persistent otitis media can develop into chronic otitis media (COM) is another 
unresolved issue.
