Evaluation of the feasibility of endoscopic tympanoplasty in two-person three-hand operation
Objective:To study the difference of postoperative efficacy between two-person three-hand ear en-doscopy and microscopic tympanoplasty in patients with chronic suppurative otitis media,and to explore the ad-vantages and disadvantages of two-person three-hand ear endoscopy.Methods:A retrospective study was conduc-ted on 100 patients who underwent tympanoplasty in the Department of Otolaryngology and Head and Neck Sur-gery of Hunan People's Hospital from April 2019 to March 2023,and they were divided into 2 groups with 50 ca-ses each according to random number table method.Among them,50 cases underwent endoscopic tympanoplasty in two-person three-hand(group A)and 50 cases underwent routine microscopic tympanoplasty(group B).The operation and postoperative conditions of the two groups were followed up.Results:In group A,the mean opera-tion time was(65.78±18.21)min,the mean intraoperative blood loss was(12.94±4.46)mL,the postoperative pain score was(1.82±0.60)points,and the mean postoperative hospital stay was(2.76±0.72)d.The mean op-eration time of group B was(89.45±20.38)min,the mean intraoperative blood loss was(22.78±5.74)mL,the postoperative pain score was(2.98±0.85)points,and the mean postoperative hospital stay was(3.82±0.75)d,which with statistical significance between the two groups(P＜0.05).Hearing in both groups was significantly improved 6 months after surgery,and the difference was statistically significant before and after surgery(P＜0.05),but there was no significant difference between the two groups before surgery and 6 months after surgery(P＞0.05).There were 2 cases in group A(4％)and 1 case in group B(2％)complicated with tympanic cord in-jury during operation,and the difference was not statistically significant(P＞0.05).There were 47 cases of A group(94％)of one-time healing of tympanic membrane after operation,48 cases(96％)of group B,and the difference was not statistically significant(P＞0.05).Conclusion:There is no significant difference in cure rate and hearing improvement between two-person three-hand ear endoscopic tympanoplasty and conventional micro-scope surgery,and the operation time is significantly shortened,the amount of blood loss is less,and the postop-erative recovery is faster.It has the advantages of clear operating field,two-person three-hand operation,mini-mally invasive,and can reach the range of middle ear tympanic sinus and mastoid apex,and the surgical complica-tions are seldom,which is worth promoting.
