1·To study morphologic changes of ear ossicles and auditory ossicular chain of patients with conductive deafness.
明确传导性耳聋的听小骨及听骨链的形态学改变。
2·Purpose: to evaluate the imaging methods and display ability of spiral ct three dimensional (3d) reconstruction of auditory ossicular chain and its clinical application.
目的：探讨正常和异常听骨链三维(3d)重建的成像方法及其临床初步应用。
3·Conclusion: 3d spiral CT could clearly demonstrate three dimensional images of the auditory ossicular chain, and is useful in evaluating diseases of the auditory ossicles.
结论：螺旋CT 3d成像能很好地显示正常和异常听骨链的立体影像，有利于听骨链病变的诊断。
4·Conclusions CTVE can clearly demonstrate a three-dimensional image of the auditory ossicular chain and is useful in evaluating diseases of the ear, especially the auditory ossicles.
结论CTVE能显示听骨链的立体影像，有利于听骨链病变的显示和诊断。
