Results regarding tympanic healing and hearing improvement are reported in a series of 84 one-stage operations on the middle ear, using thin silicone elastomer sheeting, and of 76 two-stage operations using temporary filling of the middle ear with paraffin wax, and of ten with silicone elastomer sponge. All epithelium was removed from the tympanic cleft at the primary operation. Staging of the operation gave better hearing results and resulted in fewer adhesive middle ears. Middle ear mucosal biopsies from ears with mucus production around the paraffin showed an increased number of glands and secreting epithelial cells, much as in glue ears. Residual or recurrent cholesteatoma appeared in only 2.4%, which is attributed to resection of the posterior canal wall in cases of cholesteatoma, as contrasted with the intact canal wall technique.
关于鼓膜愈合和听力改善的结果，在一系列84例使用薄硅橡胶片进行的中耳一期手术、76例使用石蜡临时填充中耳的二期手术以及10例使用硅橡胶海绵的手术中进行了报告。在初次手术时，鼓膜裂的所有上皮均被清除。分期手术可获得更好的听力结果，且粘连性中耳的发生率更低。对石蜡周围有黏液产生的耳朵进行的中耳黏膜活检显示，腺体和分泌上皮细胞数量增加，与分泌性中耳炎非常相似。残余或复发性胆脂瘤仅出现2.4%，这归因于在胆脂瘤病例中切除了后鼓室壁，这与完整鼓室壁技术形成对比。
