Dr. Hardik Shah, Dr. Neena Bhalodiya

Abstract :

Objective: To study various graft material properties like their strength, durability, avaibility and acceptability to the host. Comparison of surgical teqnique of myringoplasty onlay v/s underlay in related to he� improvement and graft take up rate. Material and method: Study was conducted in 90 patients and the demographic and clinical data were collected for success rate of type I Tympanoplasty for various graft material and onlay v/s underlay method. Result: In our study the mean average air- bone conduction gap is 28dB. we found that there is 96.66% graft taken up rate for Temporalis fascia and fascia lata, while for tragal perichondrium it is 93.33% and for vein graft it is only 73.33%. We found that out of 40 patients underwent onlay method in 37 patients graft was taken up which is 92.5% while those who underwent underlay method in 46 patients graft was taken up which is 92 %. Conclusion: Type I Tympanoplasty has a high rate of success in closing tympanic memane perforations In case of graft taken up rate and he� improvement. Temporalis fascia, tragal perichondrium and fascia lata have same successes rate. However, the surgeon should do what he/she is most experienced and successful with.
