A Comparative Study Of Endoscopic And Microscopic Type-1 Tympanoplasty

ABSTRACT

Background:Chronicsuppurative otitis media tubotympanic type is a common pathology for which tympanoplasty is done. The decision to decide the approach for tympanoplasty de pends upon multiple factors like extent of disease, site and size of perforation, size of external auditory canal and surgeon’s own expertise and preference. This study was undertaken to compare endoscopic and microscopic approach for type-1 tympanoplasty.Material And Methods:This study data was collected from 50 patients who underwent tympanoplasty in our department in our hospital from July –2017 to November 2019.Patients above 15 years of age with inactive chronic otitis media tubotympanic type operated for type-1 tympanoplasty. Pre-operative, intra-operative and post-operative data collected as per performa and evaluated.Result:Equal (25) number of cases underwent microscopic and endoscopic type-1 tympanolasty. As far as graft taken up is concern both approaches have good and comparable result. Hearing gain is almost similar in both approaches -Endoscopic approach-10.80 dB; microscopic approach-11.23 dB.Both methods do not have any major complications. Endoscopic approach has advantage of depth and angled vision. Endoscopic approach (57.2 min.) also saves surgical time than microscopic approach (89.4 min.) and comparatively good cosmetic result. Microscopic approach has upper hand over endoscopic appr oach in having two hande d surgery with magnified surgical view. Patient compliance and satisfaction is more with endoscopic approach.Conclusion:Both microscopic and endoscopic methods are excellent for type-1 tympanoplasty with advantage and limitation of each method. A careful selection of patient is necessary for endoscopic approach.
