Hearing results are presented for 164 ears with chronic otitis media which were operated on radically and obliterated with a musculo-periosteal flap (Palva flap), and in which tympanoplasty was performed. The ears were followed-up annually for 5-13 years (mean 6.8 years). Results are compared with the method of ossiculoplasty and with the condition of the stapes superstructure at operation. Ossiculoplasty using autogenous cortical bone columellas resulted in a somewhat greater improvement in the post-operative air-bone gap than ossiculoplasty with auto- or homo-graft ossicles, when compared with the pre-operative gap. Similarly, the post-operative gap improved more in ears with an intact stapes superstructure than in ears in which the stapes superstructure was absent. The use of an autogenous cortical bone columella can be recommended in cases in which the patient's own ossicles are affected by disease and cannot be used.
本文呈现了164例慢性中耳炎患者的听力结果。这些患者均接受了根治性手术，并用肌肉-骨膜瓣（帕尔瓦瓣）进行了鼓室成形术。术后对这些耳朵进行了为期5至13年（平均6.8年）的年度随访。研究结果与听骨链成形术方法以及手术时镫骨上部结构的状况进行了比较。与术前气骨导差相比，使用自体皮质骨小柱进行听骨链成形术术后气骨导差的改善程度略大于使用自体或同种异体移植听小骨进行听骨链成形术。同样，镫骨上部结构完整的耳朵术后气骨导差改善程度大于镫骨上部结构缺失的耳朵。对于患者自身听小骨受疾病影响无法使用的情况，推荐使用自体皮质骨小柱。
