Study on outcome of tympanopanoplasty: a two year institutional study

Abstract

<p class="abstract"><strong>Background:</strong> Tympanoplasty is one of the common surgical procedure performed in CSOM (TTD), this study was undertaken to determine the outcome of tympanoplasty at a tertiary care teaching hospital.</p><p class="abstract"><strong>Methods:</strong> This analytical observational study was conducted in the department of E.N.T, School of Medical Sciences and Research, from January 2017 to December 2018. Informed consent was taken to participate in the study pure tone audiometry (PTA) was performed before surgery and post-operatively six months. Air-bone gap (ABG) was calculated in pre- and postoperative PTA. The data were analyzed using SPSS (version 20). The p value ≤0.05 was considered statistically significant. </p><p class="abstract"><strong>Results:</strong> Over a peroid of 2 years 168 patients underwent type 1 tympanoplasty 86 were male 21 (51.19%), female 82 (48.80%), age (range 15–53 years). Mean pre-operative air-conduction of 43.12 dB was significantly reduced to 16.12 dB with p value of <0.05. Similarly the pre-operative mean air bone gap on PTA of 35.63±6.35 dB was also reduced to statistically significant level of 7.41±3.51 dB on post-operative PTA with p value of <0.05. Graft was taken up well in 152 cases (90.2%).</p><p class="abstract"><strong>Conclusions:</strong> According to our study surgical outcome of tympanoplasty is fairly good and should be done if patient gives consent.</p>
