Summary The effects of three different anaesthetic carrier gases on middle‐ear pressure in the operative and postoperative periods was assessed. Patients receiving oxygen and oxygen‐enriched air did not have significant changes in middle‐ear pressure. The changes associated with the use of nitrous oxide as the carrier gas were reversed with return of pharyngeal reflexes or after prolonged inhalation of 100% oxygen. In patients undergoing middle‐ear surgery or those with pre‐existing middle‐ear disease, we suggest that oxygen‐enriched air is the anaesthetic carrier gas of choice.
