Producing good local anaesthesia of the external auditory meatus and tympanic membrane has always been a difficult problem facing otologists. Previously used methods are mentioned and the use of a new eutectic mixture of local anaesthetics (EMLA) for electrocochleography, myringotomy and grommet insertion in adults and older children is described. A double-blind controlled trial involving 15 patients (30 ears) undergoing electrocochleography showed EMLA to be a very effective, safe and convenient preparation for outpatient otological use.
对外耳道和鼓膜进行良好的局部麻醉一直是耳科医生面临的难题。文中提及了以前使用的方法，并描述了一种新型局部麻醉药的共熔混合物（EMLA）在成人和大龄儿童的耳蜗电图检查、鼓膜切开术及鼓膜置管术中的应用。一项针对15例（30耳）接受耳蜗电图检查患者的双盲对照试验表明，EMLA是一种非常有效、安全且方便的门诊耳科用药制剂。
