摘要:
目的 探讨耳内镜下外耳道皮瓣-鼓环-残余鼓膜360°全掀内置法行鼓室成形术治疗鼓膜大穿孔的临床效果,并介绍临床手术要点和技巧。 方法 选择2019年7月—2021年12月在南京鼓楼医院接受鼓室成形术的鼓膜大穿孔患者30例(30耳),根据手术方式分组,其中观察组15例(15耳)接受耳内镜下外耳道皮瓣-鼓环-残余鼓膜360°全掀起后经内置法行鼓室成形术,对照组15例(15耳)接受耳内镜下常规外耳道后壁皮瓣-鼓环-残余鼓膜270°掀起后经内置法行鼓室成形术。术后随访6个月,比较2组手术时间、出血量、鼓膜愈合情况、术后听力改善情况。 结果 观察组和对照组手术时间分别为(108.33±8.28)min和(111.00±12.96)min,差异无统计学意义;手术出血量分别为(13.00±3.00)mL和(12.07±3.31)mL,差异无统计学意义。观察组术后随访6个月时鼓膜修补成功率为100.00%(15/15),对照组修补成功率为86.67%(13/15)。观察组听力改善12例(80.00%),对照组听力改善9例(60.00%),但差异无统计学意义(P>0.05)。 结论 与耳内镜下常规外耳道后壁皮瓣-鼓环-残余鼓膜270°掀起后经内置法行鼓室成形术相比,耳内镜下外耳道皮瓣-鼓环-残余鼓膜360°全掀起后经内置法行鼓室成形术在治疗鼓膜大穿孔中不仅同样具有手术时间短的优势,还可以提高患者的鼓膜修补成功率和术后听力。 Abstract:Objective To investigate the clinical effect of underlay (medial) tympanoplasty of "external auditory canal flap-tympanic annulus-residual tympanic membrane 360 degree full lift" under oto-endoscope for the treatment of large tympanic membrane perforation, and to introduce the key points and techniques of clinical surgery. Methods Thirty patients (30 ears) with large tympanic membrane perforation who underwent tympanoplasty at Nanjing Drum Tower Hospital from July 2019 to December 2021 were selected. They were divided into groups according to the type of surgery. In the observation group, 15 patients (15 ears) underwent tympanoplasty by underlay (medial) tympanoplasty after the external auditory canal flap, drum ring and residual tympanic membrane were completely opened under oto-endoscope. In the control group, 15 cases (15 ears) underwent underlay (medial) tympanoplasty after 270-degree elevation of the external auditory canal posterior wall flap, tympanic ring and residual tympanic membrane under oto-endoscope. Postoperative follow-up was conducted for 6 months, and operative time, blood loss, tympanic healing and postoperative hearing were compared between the two groups. Results The mean operating times of the observation group and the control group were (108.33±8.28) min and (111.00±12.96) min, respectively, with no statistical significance. The mean blood loss were (13.00±3.00) mL and (12.07±3.31) mL, respectively, and the difference was not statistically significant. The success rate of tympanic membrane repair at 6 months was 100.00% (15/15) in the observation group and 86.67% (13/15) in the control group. There were 12 cases (80.00%) of hearing improvement in the observation group and 9 cases (60.00%) in the control group, however, the difference was not statistically significant (P>0.05). Conclusion Compared to conventional tympanoplasty with underlay (medial) tympanoplasty after 270 degrees of external ear canal flap, tympanic annulus and residual tympanic membrane under oto-endoscope, tympanoplasty with underlay (medial) tympanoplasty after 360 degrees of full flap, tympanic annulus and residual tympanic membrane and residual tympanoplasty under oto-endoscope has the same advantages in the treatment of large tympanic membrane perforation, but it can improve the success rate of repair and postoperative hearing of patients. -
