Effects of using different materials to repair the tympanic membrane under total transcanal endoscope on the prognosis of patients with tympanic membrane perforation
Objective:To study the effects of using different materials to repair the tympanic membrane under total transcanal endoscope on the prognosis of patients with tympanic membrane perforation.Methods:70 patients with tympanic membrane perforation who were admitted to People's Hospital of Shangyou County from January 2020 to June 2023 were enrolled in this study.They were divided into the full-thickness cartilage group(35 cases)and the half-thickness cartilage group(35 cases)by the random number table method.The thickness of the full-thickness cartilage group was 1 mm,and the thickness of the half-thickness cartilage group was 0.5 mm.Both groups underwent total transcanal endoscopic myringoplasty.The two groups were compared on surgical conditions(surgical time,intraoperative blood loss and tragus healing time),hearing levels,Visual Analogue Scale(VAS)scores,average air conduction hearing thresholds and average air-bone conduction gaps before surgery and at 3 months after surgery,and the incidence of postoperative complications.Results:There was no statistically significant difference in surgical time,intraoperative blood loss,or tragus healing time between the two groups(P>0.05).There was no statistically significant difference in pure tone hearing threshold or VAS score between the two groups before surgery and at 3 months after surgery(P>0.05).There was no statistically significant difference in average air conduction hearing threshold or average air-bone conduction gap between the two groups before surgery and at 3 months after surgery(P>0.05).The incidence of complications in the full-thickness cartilage group(5.71%)was significantly lower than that in the half-thickness cartilage group(22.86%)(P<0.05).Conclusion:Using different materials to repair the tympanic membrane under total transcanal endoscope can effectively improve surgical condition,postoperative hearing level,and pain score of patients with tympanic membrane perforation.However,there are fewer complications after repair with tragus cartilage-perichondrium complex.
