Abstract
Twenty five dry, small or medium sized persistent central perforations were treated by local application of 1% hyaluronic acid after excision of the perforation rim. The duration of the perforation ranged from two months to forty years. 88 percent perforations healed with 16 ± 4 (S.D.) days using 5 ± 1.6 (S.D.) applications. Hyaluronic acid treatment of dry tympanic membrane perforations not exceeding one quadrant seems to be an alternative to surgical myringoplasty.
