本文介绍了74例陈旧性根管洞部分修复和93例陈旧性根管洞全修复的方法及初步和远期效果。在部分重建中，重建了鼓室，但没有消除鼓室，因为它是干燥的或可以保持干燥。在总重建的鼓室和耳道重建，在大多数情况下，腔闭塞，无论是通过肌肉或肌肉，耳屏软骨，和同源中隔软骨的联合移植。根据最近的结果，功能比原发性差10- 20%，讨论了旧根性空洞重建的指征。如果有慢性耳分泌物，并且如果耳腔内衬有肉芽，则90%的病例可通过全耳再造术使耳干燥。
The methods as well as the primary and late results of 74 partial and 93 total reconstructions of old radical cavities were described. In partial reconstructions the tympanic cavity was reconstructed, but the cavity was not eliminated, as it was dry or could be kept dry. In total reconstructions the tympanic cavity and auditory canal were reconstructed, and in most cases the cavity was obliterated, either by muscle or by combined grafts of muscle, tragal cartilage, and homologous septal cartilage. On the basis of the late results, functionally 10--20% poorer than the primary ones, the indications for reconstruction of old radical cavities were discussed. If there is chronic aural discharge, and if the cavity is lined with granulations, the ear can be rendered dry by total reconstruction in 90% of the cases.
