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.
在某些情况下，通过使用氧化亚氮麻醉，粘连性鼓膜（萨德IV期）可能会成功地从岬部和听小骨上抬起，并通过插入聚乙烯通气管恢复到正常位置和形态。如此恢复的鼓膜的可逆性标准和长期随访情况仍有待阐明。
