Experience with a new topical anaesthetic in otology.
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.
