RESUMO
Objective To investigate the clinical efficacy of biological amniotic membrane for otoscpic repair of traumatic perforation of tympanic membrane. Methods Otoscpic repair was performed on the patients with tympanic membrane perforation which was not healed for 6 months. The efficacy was observed postoperatively. Results The success rate of the procedure was 97.37%, except that one patient was not healing by first intention due to wound infection. Conclusions Biological amniotic membrane is definitely efficacious in the surgical repair of perforation of tympanic membrane. Otoscpic sugical repair is less invassive and has a higher success rate.
