OBJECTIVE To explore the efficacy of using tragus perichondrium under otoscope without filling to repair small perforation of tympanic membrane.METHODS A retrospective analysis was conducted on the clinical data of 32 patients who underwent surgery for small perforation of tympanic membrane in the Department of Otolaryngology,the First Hospital of Jiaxing from July 2020 to December 2022.All patients were treated with endoscopic implantation of the tragus perichondrium for tympanic membrane repair.During the operation,the tympanic cavity and external auditory canal were completely unsupported by fillers,and the patient was followed up for 6 months postoperatively.Analyze the gas conduction hearing threshold and gas bone conduction difference before and after surgery,postoperative perforation healing rate,perforation healing time,VAS score,and incidence of complications.RESULTS Thirty-two cases of small perforation of tympanic membrane were successfully treated with surgery,and the postoperative perforation healing rate was 96.88%.The average healing time was(20.1±7.61)days,and the healing morphology was good.The postoperative average hearing threshold of air conduction[(19.84±5.55)dB HL]was significantly lower than the preoperative average hearing threshold of air conduction(31.56±6.69)dB HL,and the difference was statistically significant(t=14.77,P<0.05);The postoperative average air bone conduction difference[(8.87±3.64)dB]was significantly lower than the preoperative average air bone conduction difference[(20.50±3.27)dB],and the difference was statistically significant(t=14.41,P<0.05).The postoperative VAS score of 0-3 points accounts for 93.75%.There were 2 cases of postoperative tympanitis,1 case of unhealed tympanic membrane,and no secondary cholesteatoma or facial paralysis.CONCLUSION The minimally invasive treatment of small perforation of tympanic membrane using endoscopic implantation of the tragus perichondrium without filling is a minimally invasive and effective surgical method with high postoperative healing rate,good hearing rehabilitation effect,mild pain,and few complications.
