Abstract

Aim: To determine the improvement in hearing after type I Tympanoplasty in patients with chronic suppurative otitis media.

Methods: This descriptive case series conducted in the Department of ENT, Sh. Zayed Hospital, Lahore during one year from 01-01-2019 to 31-12-2019.. Non-probability consecutive sampling technique was used.

Results: The mean age of patients was 32.91 years (standard deviation ±6.22). There were 32 (49%) male patients and 33 (51%) female patients with male to female ratio 0.96:1. The mean of disease duration was 33.29 months (standard deviation ±26.53). There were 37 (57%) patients who had <40dB air bone gap before surgery and 28 (43%) patients had >40dB air bone gap before surgery. The mean air bone gap before surgery was 42.08 dB (±6.84) and after surgery was 28.77 dB (standard deviation ±8.19). Most of the patients 56 (86%) had significantly improved hearing after tympanoplasty which is statistically highly significant (p <0.001) and only 9 (14%) patients had no improvement

Conclusion: It is found in this study that with underlay technique used for type-1 tympanoplasty, good anatomical and functional outcome can be achieved with appropriate skills and experience.
