Abstract
Introduction
With increasing popularity of Endoscopic middle ear surgeries, a better understanding of the features salient to endoscopic and microscopic tympanoplasty has gained importance. This study aims to compare the results of both.
Materials and Methods
It is a retrospective study based on MRD data collected from January 2017 to July 2018 on 40 patients with dry central perforation. 20 patients underwent endoscopic tympanoplasty and other 20 underwent microscopic tympanoplasty. Results of the surgery were compared at the end of 3 months which was based on the outcomes of surgery by means of graft uptake, comparison of pre-op and post-op audiogram readings .
Results
Eighteen cases (90%) of endoscopic surgery had mild CHL while in microscopic surgery 7 cases (35%) had moderate CHL. Average pre–op ABG was 29.05 dB in microscopic and 22.8dB in endoscopic surgery. Average post-op ABG 12.65dB and 18.4 for endoscopic and microscopic surgery. There was significant improvement in hearing gain in both the surgeries (p<0.001). Graft uptake was found to be have similar outcome.
Conclusion
Endoscopic tympanoplasty can be a good alternative of microscopic tympanoplasty but needs more training as compared to conventional method.
