A Comparative Study of Using Collagen Patch or Fat Plug in Myringoplasty for Small Tympanic Membrane Perforations

One of the most common problems in otorhinolaryngology is perforation of tympanic membrane. Although many small perforations heal spontaneously over time, some may remain persistent due to infection or some other causes. In the past years so many grafts have been used with good success rate. In this prospective study of 60 patients with small tympanic membrane perforations, we have compared newer biomaterial collagen patch and conventional fat plug as office procedures in treatment. According to our study, both groups had a significantly equal success rates & the rate of healing & complete closure at the end of 1 & 2 months follow up. The hearing improvement in A-B gap during follow up of both groups were compared with pre-op A-B gap & showed a significant p value. This showed that both collagen patch & fat plug groups had a significant improvement in hearing following procedure. In our study quadrant of perforation does not correlate with the amount of hearing & healing rates were comparatively better in anterior quadrant than posterior quadrant. Infective causes were more & the failure rates were also high for such cause in both groups.
