93 patients with an old, infected and discharging radical cavity were subjected to total reconstruction of the middle ear, especially to obtain a permanently dry ear. The cavity was obliterated and the auditory meatus reconstructed by various muscle grafts and large pieces of fascia (41 ears), by combined grafts consisting of tragal cartilage, pieces of bone, homologous septal cartilage, and muscle grafts (40 ears). In the 12 prognostically most favourable ears the cavity was repneumatized. The functional results were the same in all three groups, namely a functional success in 72%. At follow-up 1-6 years after the operation there was functional success in 62%, but 94% of the ears were dry. Obliteration of the cavity by combined grafts was at long sight more solid than obliteration by muscle. It is discussed whether, in reconstructing radical cavities, repneumatization of the cavity is preferable to obliteration, and it is concluded that at long sight a solid obliteration must afford a more stable ear than repneumatization.
93例患有陈旧性、感染性且有分泌物的乳突根治腔患者接受了中耳的全重建，尤其旨在实现耳内永久干燥。通过各种肌肉移植物和大片筋膜对乳突腔进行填塞并重建外耳道（41耳），通过由耳屏软骨、骨片、同种鼻中隔软骨和肌肉移植物组成的联合移植物进行填塞并重建外耳道（40耳）。在预后最有利的12耳中，乳突腔得以重新气化。三组的功能结果相同，即功能成功率为72%。术后1至6年随访时，功能成功率为62%，但94%的耳实现了干燥。联合移植物对乳突腔的填塞从长远来看比肌肉填塞更稳固。文中讨论了在重建乳突根治腔时，乳突腔重新气化是否比填塞更可取，并得出结论，从长远来看，稳固的填塞必定会使耳朵比重新气化更稳定。
