- Abstract: Objective To investigate the clinical efficacy of artificial dura mater and epidermal growth factor in the repair of tympanic membrane perforation after endoscopic tympanic membrane repair.Methods 58 patients with tympanic membrane perforation were randomly divided into two groups,29 cases in each.Group A was repaired with gelatin sponge,group B was repaired with artificial dura mater and epidermal growth factor.The tympanic membrane healing was reviewed every month,and the pure tone audiometry was reviewed after 3 months.Results The success rate of repair in group A was 34.48%(10/29),and that in group B was 75.86%(22/29).The difference was statistically significant(P<0.05).The air-bone gap in group A was improved by(7.32±2.68)dB HL,and that in group B was improved by(21.77±4.65)dB HL.The difference was statistically significant(P<0.05).Conclusion Artificial dura mater is a suitable tympanic membrane regeneration scaffold.Epidermal growth factor can promote the healing of tympanic membrane perforation.The combination of the two is a feasible treatment for tympanic membrane repair.
