Abstract:
Objective To investigate the clinical efficacy of continuous irrigating mode of endoscopic ear sur-gery(CIM-EES)utilizing tragus cartilage-perichondrium without tympanomeatal flap elevation in repairing tympanic membrane perforation.Methods The date of 70 patients(70 ears)who underwent tympanic membrane repair under ear endoscopy from June 2020 to August 2023 were randomly selected and analyzed.They were divided into two groups according to the time of operation:CIM-EES group(observation group)of 44 cases(44 ears)and a conven-tional surgery group(control group)of 26 cases(26 ears).Both groups were repaired with tympanic membrane per-foration using the method of implanting tragus cartilage-perichondrium grafts under endoscope without tympa-nomeatal flap elevation.After 6 months of postoperative follow-up,two groups were compared in terms of operation time,frequency of the endoscopic lens scrubbing,postoperative healing rate,and hearing improvement outcomes.Results The average operation time of the observation group and the control group was 37.50±4.81 minutes and 50.31±8.21 minutes respectively,and the average number of scrubbing the endoscope was 6.77±1.51 and 35.54±7.13 respectively,there was statistical difference significance between the two groups(P<0.01).All patients in the observation group were successfully repaired in the first stage,with the healing rate of 100%(44/44),and one patient in the control group had a postoperative small perforation that healed after secondary repair with the healing rate of 96.15%(25/26).There was no statistically significant difference between the two groups.The average 6 months postoperative air conduction threshold and air-bone conduction threshold of 0.5-4 kHz in the two groups improved compared to preoperative results(P<0.01),with no statistically significant difference between the two groups(P>0.05).Conclusion Endoscopic myringoplasty without tympanomeatal flap elevation under continuous irrigating mode has the advantages of high healing rate,short operation time,simple surgical operation,few post operation complications and good hearing improvement.
