本文提出了消除开放式乳突根治术腔防止胆脂瘤复发的新方法。即用非吸收材料甲基丙烯酸封闭术腔可达上述目的。文章阐述了封闭式乳突根治术腔的新腔可遗有残余胆脂瘤。也是引起内陷袋复发的先决条件,内陷袋能产生胆脂瘤。并阐述了开发式乳突根治术腔的缺点,需定期清耳,还难配助听器。签于上述情况,作者提出了去除陈旧性乳突根治术腔并重建声压传导装置的方法.既能重建外耳道又能封闭术腔,而不致性胆脂瘤复发。用非吸收材料甲基丙烯酸完全封闭术腔,可达永久性封闭。如有必要和可能,还可重建声压传导装置。
In this paper, a new method to eliminate the recurrence of cholesteatoma by eliminating the open mastoid cavity was proposed. That non-absorbent materials, methacrylic acid sealed chamber up to this goal. The article describes the closed mastodesis cavity of the new cavity can be left with residual cholesteatoma. It is also a prerequisite for causing the recurrence of a depressed pocket, which can produce cholesteatoma. And expounded the shortcomings of the development of radical mastoidectomy cavity, the need to regularly clean ears, but also difficult to wear hearing aids. Sign in the above situation, the authors proposed to remove the old radical mastoid cavity and reconstruct the sound pressure conduction device method can not only rebuild the external auditory canal but also close the cavity, and not recurrence of cholesteatoma. With non-absorbent material completely closed the chamber of methacrylic acid, up to permanent closure. Sound pressure transducers can also be rebuilt if necessary and possible.
