A Comparative Study of Transcanal OTO Endoscope Assisted Myringoplasty Vis-à-vis Conventional Myringoplasty

To evaluate the role of Otoendoscope and microscope in the management of dry central perforation of tympanic membrane and to compare the result of otoendoscopic myringoplasty with conventional microscopic myringoplasty.

A prospective study of 40 patients with dry central perforation with conductive hearing loss 20 in each group of otoendoscopic myringoplasty and microscopic myringoplasty for three years at Post graduate Department of Otorhino laryngology and Head & Neck Surgery Govt. Medical College, Srinagar.

In our study in the endoscopic group the graft take up was observed in 16/20 (80%) and in microscopic group 17/20 (85%). Regarding hearing results in endoscopic group patients 18/20 (90%) which were in the range of 21–50 db air conduction preoperatively were found on post operative 16/20 (80%) air conduction threshold 0–20 db likewise in microscopic group 19/20 (95%) patients which were in the range of 21–50 db air conduction threshold were found post operatively 17/20 (85%) air conduction threshold 0–20 db.

In our study anatomical and functional out comes of endoscope assisted myringoplasty were comparable to the conventional microscope assisted myringoplasty. In terms of cosmesis and post operative recovery patients in the endoscopic group had better results.
