Abstract:
OBJECTIVE To compare the short-term efficacy of autologous frozen tragus perichondrium and fresh perichondrium in repairing tympanic membrane perforations,and to explore the clinical application value of autologous frozen tragus perichondrium.METHODS Twenty-five patients with bilateral tympanic membrane perforations from March 2021 to October 2023 were selected,including 7 males and 18 females.Bilateral tympanoplasty was completed in stages.The initial operation was set as the control group,in which the ventral perichondrium of the tragus was used for tympanoplasty,and the dorsal perichondrium of the tragus was reserved and stored at-80℃ultra-low temperature in a sterile container.The second operation was set as the observation group,in which the thawed frozen perichondrium was used for contralateral tympanoplasty.The differences in the healing rate of tympanic membrane,postoperative hearing,operation time and surgical bleeding volume were compared between the two groups.RESULTS All patients were followed up for three months.The success rate of tympanic membrane healing in the observation group was 96%(24/25),and that in the control group was 92%(23/25).There was no statistically significant difference between the two groups(χ2=0.36,P>0.05).The operation time and surgical bleeding volume of patients in the observation group were lower than those in the control group[(48.64±4.64)min vs.(67.92±5.69)min,(5.32±1.54)ml vs.(9.65±1.73)ml],and the differences were statistically significant(t=13.93,t=12.09,P all<0.05).The postoperative air conduction hearing thresholds and air-bone conduction gap of the two groups of patients were lower than those before operation(all P<0.05).There was no difference in air conduction hearing threshold,bone conduction hearing threshold and air-bone conduction difference between the groups(all P>0.05).CONCLUSION The application of autologous frozen tragus perichondrium has effectively shortened the operation time of the contralateral ear,avoided the trauma caused by taking materials again,and has the characteristics of minimally invasive and high efficiency.The method is feasible and the curative effect is accurate.
