COMPARISON OF THE EFFICACY OF ENDOSCOPIC TYMPANOPLASTY WITH MICROSCOPIC TYMPANOPLASTY

Introduction: Otological surgery has progressed rapidly over the past century. With the recent introduction of the 3-chip camera system and high denition video systems, endoscopes now provide ultra high resolution images of the middle ear that were never seen previously. We conducted this study to compare the efcacy of endoscopictympanoplasty over microscopic tympanoplasty in terms of preoperative ease of surgery including visualisation of ossicles and eustanchian tube and intraoperative bleeding, graft uptake, hearing improvement, post-operative pain score, post-auricular hypoesthesia, duration of hospital stay etc. Methods: The present study is prospective observational study, conducted in a Tertiary Health Care Centre. Results: Endoscopic tympanoplasty has many advantages over microscopic tympanoplasty and can be a better alternative or adjuct to microscopic tympanoplasty. Conclusion: Endoscopic ear surgery provides a better magnication, wide eld view, and the ability to look around corners. Further more transcanal endoscopic ear surgery (TESS) approaches transform external auditory canal into a minimally invasive surgical portal to access middle ear disease. The ease of surgery improves with time and has a gradual learning curve. The graft uptake rate is comparable with both approaches. The overall satisfaction score in terms of reduced pain and hypoesthesia with decreased hospital stay is higher in endoscopic approach.
