摘　　要：Objective:Various materials have been used for tympanic membrane reconstruction in middle ear surgery.This study aimed to evaluate the difference between the tragal perichondrium and COOK arti-ficial material in patients who underwent endoscopic type 1 tympanoplasty.Method:This retrospective study included patients who underwent endoscopic type 1 tympanoplasty from June 2021 to June 2022 at Sir Run Run Shaw Hospital,Zhejiang University School of Medicine.Patients were divided into group A(tragal perichondrium)and group B(COOK artificial material)ac-cording to the material used in the operation.All patients were followed up for 6 months.The differences in age,gender,operation site,disease course,preoperative air-bone gap(ABG),operation time,blood loss,hearing gain,and wound healing rate were compared between the two groups.Results:This study enrolled 197 patients,with 120 patients in group A and 77 patients in group B.There were no significant differences in age,gender,operation site,disease course,or preoperative ABG be-tween groups A and B(p>0.05).Both groups had significant postoperative improvement in hearing(group A:30.98±9.58 dB vs.17.07±9.92 dB,p<0.001;group B:29.75±7.52 dB vs.14.25±9.07 dB,p<0.001).The mean hearing gain in group A and group B was comparable(14.02±11.91 dB vs.15.50±7.05 dB,p=0.609).The wound healing rates of groups A and B were no differences(93.33%vs.87.01%,p=0.133).The patients in group B had a shorter operation duration(72.57±11.32 min vs.61.86±9.27 min,p=0.045)and less blood loss(12.38±3.7 mL vs.8.10±2.43 mL,p=0.004).Conclusions:Tragal perichondrium and COOK artificial material are reliable for functional and anatomical outcomes in endoscopic type 1 tympanoplasty,and COOK artificial material can save operation time and blood loss in surgery compared to the tragal perichondrium.
