title: Atelectatic tympanic membrane reversal by nitrous oxide supplemented general anesthesia and polyethylene ventilation tube insertion. A preliminary report.
abstract: In certain instances an adherent atelectatic tympanic membrane (Sade Stage IV) may be successfully elevated off the promontory and ossicles by the use of nitrous oxide anesthesia and restored to a normal position and configuration by polyethylene ventilation tube insertion. Criteria of reversibility and long term follow-up of the tympanic membranes so restored remain to be elucidated.
