Background

The study aims at reporting our experience with loop underlays tympanoplasty, a modification of the underlying technique previously reported, for the reconstruction of anterior, subtotal or total tympanic membrane perforations.

Methods

A retrospective review of charts of patients who have undergone loop underlay tympanoplasty from January 2002 to January 2012 was performed. One thousand one hundred patients were included. Hearing test results preoperatively and postoperatively were reported. On follow up visits, the closure of the tympanic membrane perforation and the improvement of hearing compared to preoperative measurements with the absence of complications were considered as successful outcomes of the surgery.

Results

At the three-month follow-up visit, the perforation closure rate was found to be 99.3% and Air-Bone Gap closure rate to less than 10 dB was 99.5%. The complication rate, including postoperative infection, was 0.72%.

Conclusion

The loop underlay technique combines the advantages of both underlay and overlay techniques with excellent postoperative outcomes.
