Introduction:
Incorrect and inadequate treatment of Chronic otitis media may cause serious complications. Tympanoplasty is a common operation used to eradicate infection and reconstruct the ear drum.
Aims:
We analyzed the results of endoscopic and microscopic approaches for type 1 tympanoplasty in patients with simple chronic otitis media. we compared patients who received endoscopic and microscopic approach type 1 tympanoplasty with the results of hearing improvement, operation duration and perforated cases after at least a 6-month follow-up period.
Material and Methods:
We evaluated the records of 95 patients (100 ears) who underwent type 1 tympanoplasty from 2011 to 2014. Group 1 underwent tympanoplasty with a microscopic approach (50 ears), and Group 2 underwent tympanoplasty with an endoscopic approach (50 ears). The epidemiological profiles and postoperative results including hearing gain, duration of surgery, perioperative nausea or vomiting, and graft success rate were reviewed.
Results:
The epidemiological profiles and preoperative hearing status were similar in both groups. Postoperatively, both groups had equal improvements in hearing and air-bone gap, and an equal perforation rate. However, the endoscopic group suffered less perioperative nausea or vomiting, and had a shorter operative time.
Conclusion:
The endoscopic approach for tympanoplasty offers superior visualization, shorter operative time, equal hearing outcomes and perforation rate to conventional surgery. In addition, fewer tissue injuries, better cosmetic outcomes and less perioperative nausea and vomiting suggest that the endoscopic approach is a better choice of surgery.
