Abstract: Objective To investigate the curative effect of endoscopic tragus cartilage ring perichondrium myringoplasty. Methods Eighty patients(80 ears)with tympanic membrane perforation were randomly divided into observation(endoscopic ear cartilage perichondrium composite ring repair)and control groups(temporalis fascia myringoplasty using an operating microscope), with 40 cases in each group. Clinical indexes, efficacy, tympanic membrane healing rates, hearing recovery, and the incidence of postoperative complications were compared between the two groups. Results The operative time and the amount of bleeding in the observation group were lower than those in the control group(P<0.05). The total efficacy rate in the observation group was higher than that in the control group(P<0.05). The tympanic membrane healing rate in the two groups was not statistically different after 1, 6, and 12 postoperative months(P>0.05). There was no significant difference in hearing recovery between the two groups after 1, 6, and 12 months(P>0.05). There was no significant difference in the incidence of postoperative complications between the two groups(P>0.05). Conclusion Use of endoscopic ear tragus cartilage ring perichondrium myringoplasty to reduce postoperative bleeding shortens the operative time and healing rate, with good clinical curative effect, and can improve hearing, making it clinically useful.
