钨针电刀在耳内镜鼓膜修补手术中的应用

目的 探讨钨针电刀在耳内镜鼓膜修补手术中的应用.方法 选取2018年8月-2019年8月住院行耳内镜鼓膜修补的患者85例.其中采用外耳道皮瓣刀行外耳道内切口的40例为对照组,采用钨针电刀行外耳道内切口的45例为观察组,对比分析两组患者手术中和手术后效果.结果 观察组比较对照组切口时间短、切口出血量少、术中镜头擦拭次数少...

Application of Tungsten Needle Electrotome in Endoscopic Myringoplasty

Objective To report application of tungsten needle electrotome in endoscopic myringoplasty.Methods Eighty five patients underwent endoscopic myringoplasty from August 2018 to August 2019,with ear canal incision made using a knife(n=40,control group)or a tungsten needle electrotome(n=45,study group).Treatment outcomes of the two groups were compared.Results The observation group compared the control group with short incision time was shorter with less bleeding and less lens wiping during surgery in the study group,requiring less use of sponge particles as compared to the control group(t=-13.6,-9.0,-7.6 and-12.8,P<0.05),and similar in terms of healing time and postoperative outer ear canal stenosis.The disadvantage for the study group included smoke generated during electrotome use that required an assistant to help remove smoke.Conclusion The small and flexible tungsten needle electrotome allows fine and accurate maneuvers,providing the advantage of reduced incision bleeding and shortened operating time,and is suitable for application in otoendoscopic surgery via the external auditory canal.
