A common observation during otologic surgery under general anaesthesia, notably with nitrous oxide, is tympanic membrane graft displacement due to elevated intratympanic pressure. It can be assumed that nitrous oxide increases the intratympanic pressure. The authors measured the intratympanic pressure changes with the Madsen Impedance measuring instrument Z073. The results of the measurements of 84 ears are discussed and the tendencies of the connection between pressure in the middle ear and the size of the mastoid bone are shown.
在全身麻醉下进行耳科手术时，尤其是使用一氧化二氮时，常见的观察结果是由于鼓室内压力升高导致鼓膜移植片移位。可以推测一氧化二氮会增加鼓室内压力。作者使用Madsen阻抗测量仪Z073测量了鼓室内压力变化。讨论了84只耳朵的测量结果，并展示了中耳压力与乳突骨大小之间联系的趋势。
