Abstract
Objectives:
One of the most important factors in the success of myringoplasty is the size of the perforation. The repair of subtotal and large central perforation is less likely to be successful compared with the repair of small perforations. Loop overlay technique of myringoplasty offers an advantage in these situations and can be a viable alternative.
Methods:
A prospective controlled study from January 2010 to December 2011 of inactive (mucosal) chronic otitis media with subtotal and large central perforations. Subjects: Forty cases of either sex in the age group of 18-40 years. Pt. B.D.S Post graduate Institute Medical Sciences Rohtak, India, a tertiary care center. Patients were randomly divided into 2 groups of 20 each. Group A underwent medial myringoplasty and Group B Loop overlay myringoplasty. The graft uptake rate and the preoperative and postoperative hearing thresholds in each group were analyzed. Independent variables: Size and location of the perforation, preoperative air bone gap, technique of myringoplasty used.
Results:
The overall graft take-up rate in group A was 90% and in group B it was 95%. Further, the average postoperative gain in group A was 16.25 dB as compared to 18.5 dB of group B.
Conclusions:
Loop overlay myringoplasty is better than medial myringoplasty in subtotal and large central perforations.
