A 5 YEAR PROSPECTIVE COMPARATIVE STUDY OF ENDOSCOPIC VERSUS MICROSCOPIC TYMPANOPLASTY IN A TERTIARY CARE CENTRE OF SOUTH INDIA.

CONTEXT: Type 1 tympanoplasty is one of the commonest performed surgeries by otolaryngologists across the world. Endoscopic ear surgeries (EES) are gaining more popularity in recent times. The objective of this study is to evaluate the outcomes of endoscopic type 1AIMS: tympanoplasty and compare with that of microscopic tympanoplasty A prospective observational comparative studySETTINGS AND DESIGN: of two surgical techniques was conducted in a tertiary care hospital of south India from 2015- 2019. All patientsMETHODS AND MATERIAL: underwent type 1 tympanoplasty either endoscopic or microscopic using temporalis fascia graft. S StatisticalTATISTICAL ANALYSIS USED: package for the social sciences (SPSS) version 17 was used to analyse the data. Chi square test/Fisher's exact test was used to analyse the qualitative data. Student t test was used to analyse the quantitative data A total of 152 patients who satised the study criteria were included in this. RESULTS: study. 80 patients underwent endoscopic tympanoplasty (Group A), while 72 patients microscopic tympanoplasty (Group B). Both the groups were comparable with respect to age gender, size and location of perforation. The mean operative time for group A and group B were 45.3 ± 7.1 and 50.2± 8.1 mins respectively (P=0.01). Successful graft uptake was observed in 75/80(93.75%) and 68/72(94.4%) in group A and group B (P= 0.45). Mean pre and post operative ABG were 30.2 ± 3.2 dB &29.8± 3.6 dB and 11.6± 1.8 dB & 11.9± 2 dB respectively (p= 0.32 and P=0.24). Group A had better post-operative VAS scores(P=0.01) and lesser canalplasty requirement(p=0.04) In this study, the hearing results ofCONCLUSIONS: endoscopic and microscopic tympanoplasty were comparable and no signicant difference was observed. However, endoscopic tympanoplasty had better outcomes in terms of lesser canalplasty requirement and post operative pain scores.
