The methods, results, and indications for operation on only hearing ears are discussed on the basis of 13 patients operated upon for chronic otitis media and its sequelae. Although good results were obtained, with an air-bone gas closure within 15 dB. in 77 per cent, this should not serve as propaganda for the general use of surgery on only hearing ears. On the other hand, they show that surgery on only hearing ears should not be rejected a priori and that on certain indications and under c ertain circumstanc es it may be carried out with minimal risk of aggravating the hearing loss. In most of the patients the indication for surgery was a progressing cholesteatoma, in some cases the sequelae of otitis, either in the form of myringoplasty or type II tympanoplasty, and one patient had the operation on a vital indication. To avoid postoperative exacerbation of the hearing, the patients must be strictly selected, the ears have to be pretreated conservatively, the Eustachian tube must be passable, the operation must be carried out by the most experienced otosurgeon, and thoroughly tested, very gentle operative methods must be used.
基于13例因慢性中耳炎及其后遗症接受手术的患者，讨论了仅对单耳听力耳进行手术的方法、结果及适应证。尽管取得了良好的效果，77%的患者气骨导差在15分贝以内，但这不应用作普遍对单耳听力耳进行手术的宣传。另一方面，这些结果表明，不应先验地拒绝单耳听力耳手术，在某些适应证和特定情况下，手术造成听力损失加重的风险可能最小。大多数患者的手术适应证是进行性胆脂瘤，在某些情况下是中耳炎后遗症，采用鼓膜成形术或II型鼓室成形术，还有1例患者是因重要适应证接受手术。为避免术后听力恶化，必须严格挑选患者，耳部必须进行保守预处理，咽鼓管必须通畅，手术必须由经验最丰富的耳外科医生进行，且必须采用经过充分测试、非常轻柔的手术方法。
