Medial versus Medio-lateral Tympanoplasty in Large Central and Subtotal Perforation – A Prospective Study
Article Sidebar
Main Article Content
Abstract
Introduction:
Large central and subtotal tympanic membrane (TM) perforations are difficult to repair because of less vascularity of anterior TM than posterior TM and the anterior bony overhang that blocks visualization. Some studies reported very encouraging results with the medio-lateral tympanoplasty in such cases. We have undertaken this study to find out efficacy of this technique in large central and subtotal perforations and to compare the results of medio-lateral with medial tympanoplasty.
Materials and Methods:
The present prospective study was conducted in the Department of Otorhinolaryngology of a medical college and hospital, West Bengal from January 2013 to December 2014. Patients were alternatively divided into two groups. Medial technique was used in Group I and medio-lateral technique was used in Group II.
Results:
Each group comprised of 40 patients each. Maximum number of patients in each group was in the age group of 15-25 years. The overall graft uptake rate in this study was 95% in medio-lateral technique compared to 80% of underlay technique.
Conclusion:
The medio-lateral tympanoplasty is suitable for reconstruction of large central or subtotal TM perforation. It takes advantage of both medial and lateral grafting methods while avoiding their pitfalls.
