Tympanoplasty was developed to repair a perforated tympanic membrane. Microscopic tympanoplasty remains the main surgical procedure while endoscopic tympanoplasty has become popular with its minimal invasive advantage.

The present study was to compare the clinical outcome of the endoscopic and microscopic tympanoplasty.

Patients and methods:
The retrospective comparative study enrolled patients who underwent type 1 tympanoplasty at the Department of Otolaryngology-Head and Neck Surgery, Chang Gung Memorial Hospital, Taoyuan, Taiwan. The subjects were classified into 2 groups:  microscopic assisted tympanoplasty and endoscopic assisted tympanoplasty. Demographic data, perforation size of tympanic membrane at preoperative state, perforation location, pure tone audiometric results preoperatively and postoperatively, and postoperative graft take rate were evaluated.

Both the endoscopic and microscopic assisted tympanoplasty had similar take rate. However, the audiometric results were mild difference. We will present our data and discussion at the conference

Endoscope has become more popular can shorten surgical time. It can also cause less trauma and has well cosmesis to patients. Loss of depth perception and one handed technique are not the disadvantage in endoscopic tympanoplasty.
