Summary The effect of two methods of anaesthesia on the findings at myringotomy in children with secretory otitis media was studied. One group of patients spontaneously breathed a mixture of nitrous oxide. oxygen and halothane whereas a second group had assisted ventilation, tracheal intubation and breathed a mixture of halothane and oxygen. Nitrous oxide diffused significantly into middle ears which had gas under reduced pressure (with or without fluid present) when compared with normal ears (p <0.05). Assisted ventilation prior to tracheal intubation did not introduce gas into the middle ear. It is concluded that impedance audiometry is a reliable method of assessing the middle ear prior to surgery.
