Transtympanal insufflation of the inert gas SF6 in cases of atelectasis mostly makes the atrophic tympanic membrane shift lateral, thus reaching a better functional position. The pathological tympanogram may become almost normal after insufflation. Model studies show that this is not only caused by equalisation of possible negative pressures but also by the enlargement of the middle ear volume and the improved position of the tympanic membrane.
在肺不张病例中，向鼓室内注入惰性气体六氟化硫（SF6）大多会使萎缩的鼓膜向外移位，从而达到更好的功能位置。注入气体后，病理性鼓室图可能几乎恢复正常。模型研究表明，这不仅是由于可能存在的负压得以平衡，还因为中耳容积增大以及鼓膜位置改善。
