A Study of Different Otologic Prognostic Factors Determining the Hearing Outcome in Surgical Management of Chronic Otitis Media Squamous Disease

Introduction
The diagnosis of chronic otitis media (COM) implies a permanent abnormality of the pars tensa or flaccida. The definitive treatment of it is surgery. Restoration of hearing is by necessity a secondary consideration.
Materials and Methods
A prospective study was done from December 2017 to August 2019 in Department of ENT in a tertiary health care centre of eastern India. Total 50 patients were included in this study.
Results
Most of the patients (62%) are females and are within 30 years of age. Commonest ossicular defects are defects with incus. 82% patients gained hearing improvement >15 dB.
Conclusion
Our study shows that hearing improvement is greatest for type I tympanoplasty followed by cortical mastoidectomy, ossiculoplasty. Hearing improvement is inversely proportional to the incidence of post operative infection and complications.
