尽管用于听骨链重建有各种各样的移植材料,其效果均不理想。该文对41例慢性化脓性中耳炎采用异体茎突行听骨链重建术5年以上的患者进行了回顾性研究,以探讨此种移植材料的临床应用价值。41例慢性化脓性中耳炎中35例鼓膜中央性干性穿孔,余为胆脂瘤。全部病例槌骨和镫骨上部结构完整,而砧骨长突坏死。胆脂瘤患者均行鼓室乳突切开术并同时或分期行听骨链重建术。切取死亡6小时内新鲜人尸体颞骨茎
Although used in the reconstruction of ossicular chain, a variety of graft materials, the effect is not satisfactory. In this paper, 41 patients with chronic suppurative otitis media were treated by allogeneic stem-line reconstruction for more than 5 years to investigate the clinical value of this graft material. Thirty-five patients with chronic suppurative otitis media had central perforation of the tympanic membrane, and the remaining were cholesteatoma. In all cases, the suprapubic and tarsal structures were intact, while the incus medulla oblongata died. Patients with cholesteatoma underwent tympanotomy and at the same time or in stages underwent ossicular chain reconstruction.
