To evaluate the hearing results following ossicular reconstruction in patient with chronic secretory otitis media.

Abstract

Background: Chronic infection of middle ear is a widely prevalent condition in India like it is in the other developing countries. Chronic otitis media erodes the bone, destroys the ossicles and has the potential to cause life threatening complications.

Methods: This is a prospective study involving patients with chronic otitis media. The study had been conducted between Jun-2014 and June-2016 .90 patients were included and all of them are subjected to ossicular reconstruction either by canal wall down or intact canal wall surgery.

Results: The mean (±SD) in group 1A pre op A-B gap was 35.45±12.7 and post op A-B gap was 23.4±7.18 and hence giving highly significant result i.e. p <0.001. In group 1B pre op A-B gap was 36.15±14.8 and post op A-B gap was 23.6±8.8 and hence giving highly significant result i.e. p <0.001.In group 1C pre op A-B gap was 34.55±12.7 and post op A-B gap was 25.15±8.59 and hence giving highly significant result i.e. p <0.001.The mean (±SD) in group 2A pre op A-B gap was 34.15±10.61 and post op A-B gap was 25.4±9.19 and hence giving highly significant result i.e. p <0.001. In group 2B pre op A-B gap was 36.5±11.05 and post op A-B gap was 23.8 ±7.74 and hence giving highly significant result i.e. p <0.001.In group 2C pre op A-B gap was 35.5 ±12.4 and post op A-B gap was 24.6±8.24 and hence giving highly significant result i.e. p <0.001.

Conclusion: All the three modalities gave statistically significant improvement (p < 0.001) in A-B gap leading to improvement in hearing but among the three groups there was no statistically significant (p > 0.05) difference found in improvement of A-B gap.
