[Bilateral sensorineural hearing loss after general anesthesia].

A bilateral sensorineural (perceptive) deafness occurred in a 12-year-old girl, following laparoscopic appendicectomy under general anaesthesia not comprising nitrous oxide and low insufflation pressures and a normal haemodynamic status. There was neither a personal nor a familial history of hearing disturbances nor a preoperative intake of ototoxic drugs. The initial loss of 50 dB has been substantiated by evoked auditive potentials.
