An Observational Study on Butterfly Underlay Cartilage Tympanoplasty.

Background: The paring of tympanic membrane is usually done by doing myringoplasty with temporal is fascia graft. Methods: A newer technique of butterfly cartilage underlay grafting has been used in 50 patients with small to moderate size safe perforation. Results: The result of the study would be analysed for hearing improvement and graft uptake. Hearing gain of 0-5 dB was observed in 4 patients, 6-10 dB in 3 patients, 11-15 dB in 14 patients, 16-20 dB in 22 patients and 21-25 dB in 7 patients. Conclusion: Butterfly cartilage myringoplasty is a very good technique for closure of small to moderate size central perforations.
