Type 1 tympanoplasty: does the status of contralateral ear affect the outcome?

Arindam Das, Sandipta Mitra, Debasish Ghosh, Arunabha Sengupta


Background: The objective of the study was to investigate the effect of contralateral ear status on the success rate (anatomical closure) of type 1 tympanoplasty.

Methods: The study is a prospective observational study comprising of 60 patients diagnosed with chronic otitis media, who underwent type 1 tympanoplasty during 2016-2018 in a tertiary care hospital.  

Results: In our study, contralateral ear was normal in 40 (66.7%) cases & diseased in 20 (33.3%) cases. Success rate of type 1 tympanoplasty in patients with normal contralateral ear was 90% (n=36) but success rate was only 60% (n=12) in diseased contralateral ear. This was statistically significant (p=0.006).

Conclusions: Our study revealed that the status of the opposite ear is an individual prognostic factor for type 1 tympanoplasty. In other words, graft-healing rates are poorer in individuals whose opposite ears are atelectatic or perforated because of chronic otitis media.
