The study aimed to evaluate the clinical application of CO2 laser myringotomy in children with otitis media with effusion (OME) under topical anaesthesia in an office setting.
Laser myringotomy was performed with the CO2 laser Otoscan (OtoLAM) in 54 children (73 ears) with OME. The procedure on the tympanic membrane was performed under topical anaesthesia using Bonain's solution or 10 per cent Xylocaine (lidocaine) solution for 30 minutes before surgery. A circular perforation was created with a power of 15 W, single pulse duration of 200 msec and a scanned area of 1.9 mm in diameter.
The mean healing time was 2.51 weeks (range 1-5 weeks). Effusion content was not a predictive prognostic factor for perforation healing time. Perforation location over anterior inferior or posterior inferior quadrants was not a predictive factor for perforation healing time. Xylocaine was the more effective anaesthestic. The OME resolution rate was 73 per cent.
Laser myringotomy provides intermediate duration middle-ear ventilation. It could be beneficial in selected children with OME.
本研究旨在评估在门诊环境下局部麻醉时,二氧化碳激光鼓膜切开术在分泌性中耳炎(OME)患儿中的临床应用。
使用二氧化碳激光耳镜(OtoLAM)对54例(73耳)OME患儿进行激光鼓膜切开术。在手术前30分钟,使用博纳因溶液或10%的赛罗卡因(利多卡因)溶液对鼓膜进行局部麻醉。以15瓦的功率、200毫秒的单脉冲持续时间和直径1.9毫米的扫描区域制作圆形穿孔。
平均愈合时间为2.51周(范围1 - 5周)。积液量不是穿孔愈合时间的预测性预后因素。前下象限或后下象限的穿孔位置不是穿孔愈合时间的预测因素。赛罗卡因是更有效的麻醉剂。OME的治愈率为73%。
激光鼓膜切开术可提供中等时长的中耳通气。它可能对特定的OME患儿有益。
