ABSTRACT
Background: Tympanoplasty is a common operation performed by ENT specialist. It is a challenging event to treat with a microscope when the external canal is narrow or overhang. The endoscopic permeatal approach gives the advantage of wide angle view and can avoid post-auricular approach and canaloplasty. The aim of the study was to compare the outcome of tympanoplasty in post-auricular microscopic and permeatal endoscopic approach.Material &Methods:A total of 100 patients between the age group 15 to 44 years who were attending the ENT OPD, suffering from Chronic Suppurative Otitis Media (CSOM) were selected on the basis of perforation type and their workup was done to assess the candidature for tympanoplasty. Comparative analysis between the two groups were done based on analysis using SPSS 24 software version. The level of significance was set to 5% (P<0.05).Results:A total of 100 patients were included in the study the overall graft take was 92.3% in cases of Endoscopic permeatal technique as compared to 88.88% in the case of Microscopic postaural underlay technique, with a majority of the failures in the large central perforation group rendering a p = 0.021 for patients operated for Large perforations, p=0.036 or moderate perforations and p = 0.0476 for small perforations. There was a difference in hearing improvement with majority of the cases improving to the range of 10-21 dB in permeatal endoscopic technique compared to 07-18 dB in postauralMicroscopic technique.Conclusion:In terms of graft take rate, hearing improvement and complications, the permeatal endoscopic method outperforms the postauricular microscopic approach.
