Results CTVE could clearly demonstrate the shape,size,and relation of the normal auditory ossicular chain.A visualization rate of malleus,incus,and incudomalleal articulation was 100%,and was 32% for the stapedial footplate.However,in only 21% could the anterior and posterior crura of stapes be distinguished.Cholesteatoma was found in 12 cases with chronic otitis media,in which CTVE demonstrated varying degrees of destruction of the auditory ossicle.In 1 case with congenital anomaly,ossicle dysplasia was seen.

结果 CTVE能清楚显示正常听骨链的形态、大小及相互关系，锤骨、砧骨及锤砧关节的显示率为100%(38/38)，镫骨底板的显示率为32%(12/38)，只有21%(8/38)可以分辨镫骨的前、后脚；18例中耳炎患者中12例胆脂瘤形成，CTVE上有不同程度的听小骨破坏。1例中耳畸形显示听骨链发育异常。

METHODS: The China Joumal Full-text Database was undertaken to identify the articles on ossicular chain reconstruction materials published from January 1998 to June 2007 with the key words of ＂artificial ossicle, ossicular chain reconstruction, biocompatibility＂ in Chinese.

应用计算机检索中国期刊全文数据库1998—01／2007—06有关昕骨链重建材料方面的相关文献，检索词"人工听骨、听骨链重建、生物相容性"，限定文献语言种类为中文。

To clear a sclerotic region around the stapes and to reconstruct ossicular chain and tympanic membrane are the key points of success. The response is closely related with the sclerotic region around the ossicular chain.

Ten patients with temporal bone fracture and trauma of ear,whose CT scan of temporal bone showed that Malleoincudal joint irregular shape in the axial view and incudostapedial joint dislocation in the coronal view,were included in this study,Virtual endoscopy showed Malleoincudal joint separation,incudostapedial joint dislocation and interruption,ossicular chain disruptio...

虚拟耳镜示锤砧关节分离，砧镫关节脱位，听骨链中断。手术经颞线下开放上鼓室，保留完整的外耳道后上壁，充分暴露上、后鼓室和听骨链，检查并行听骨链成形术。结果：砧骨长脚骨折1耳，将砧骨改型后行锤-镫连接术；锤砧和砧镫关节脱位6耳，砧骨完全脱落3耳，行砧骨复位双关节固定术。10耳均行上鼓室进路鼓室探查术，术后语频听力平均提高25~50dB。结论：完壁式上鼓室进路鼓室探查术治疗外伤性听骨链中断疗效满意。

PORP could be a useful material for ossicular reconstruction and hearing improvement was obtained after operation for otitis media patients.

PORP是一种可在听骨链重建中推广的人工听骨材料，术后取得良好的听力效果，但应注意避免术后听骨脱出。

Results There was no significant difference in hearing results between the bioceramic and titanium ossicular protheses in regard to the management of mastoid lesion, the methods of ossiculoplasty.

根据不同型号的人工听骨植入，两组无论哪种人工听骨植入方式，术前、后ABG差值没有组间差别。两组术前、后ABG差在组间没有统计学差异。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
