咽鼓管功能不良和乳突气化不全的患者作鼓膜修复术的成功率一般不超过50％。如仅有咽鼓管功能不良而乳突气化良好者,可代偿咽鼓管功能,如乳突气房面积大于9平方厘米者,则效果更好。咽鼓管鼓室端的机械性阻塞,目前尚无治疗办法,但广泛开放乳突气房较易进行。因此对咽鼓管功能不良需行耳部手术者,应彻底开放乳突气房使形成一大腔,上至鼓室天盖,后至乙状窦板,前达颧根,开放上鼓室及鼓窦入口,使乳突腔与鼓室广泛交通,术合乳突腔覆盖0.05厘米厚的塑料薄膜,亦修复鼓膜,术后成功率可达83％。
Eustachian tube dysfunction and mastoid gasification in patients with tympanic membrane repair the success rate is generally not more than 50%. If only the eustachian tube dysfunction and mastoid gas well, can compensate for eustachian tube function, such as mastoid air room area greater than 9 square centimeters, the better. Eustachian tube tympanic end of the mechanical obstruction, there is no treatment, but the wide open mastoid air chamber easier to carry out. Therefore, dysfunctional eustachian need ear surgery, should be completely open the mastoid air chamber to form a large cavity, up to the tympanic canopy, after the sigmoid sinus, before the zygomatic root, open the upper drum and drum Sinus entrance, the mastoid cavity and tympanum widely traffic, mastoid cavity covered 0.05 cm thick plastic film, also repair the tympanic membrane, the success rate of up to 83%.
