Effect of the weight of cartilage and fascia grafts on the audiological outcome of myringoplasty

BACKGROUND: This study was conducted to determine whether the weight of the graft has any effect on the hearing results of myringoplasty.
METHODS: Sixty patients with nearly equal variants namely, age, sex, the site and size of the perforation, and air bone gap, were divided randomly into two groups. Group I participants were operated for transcanal fascia myringoplasty, while Group II were operated for transcanal cartilage myringoplasty. For both groups, accurate measurement of the weight of the finally designated grafts was done by micro analytical balances. Pure Tone Audiometry as regarding 500Hz, 1000Hz, 2000Hz, and 4000Hz was done three months after successful surgery.
RESULTS: The mean weight of the finally designated cartilage graft was 20±4.36 mg, while that of fascia was 8.23±3.25 mg, and both types of surgery significantly improved hearing. No statistically significant difference was detected between the audiological outcomes of both variants of surgery in all examined frequencies for air and bone conduction hearing.
CONCLUSIONS: Although the mean weight of the cartilage graft was more than twice as much as the weight of the fascia graft, there was not any audiological difference between cartilage and fascia myringoplasty.
