Abstract
Objective TO discuss and analysis the diagnostic method, scope and value to the ossicular chain in the CT imagine in order to help otologists and radiologists get mastery and understanding. Materials and Methods The five typical cases, including cholesteatoma otitis media, chronic suppurative otitis media, congential auval deformity tympanosclerosis and ossicular chain discontinuity, were assessed by axial and coronal high resolution CT (HRCT)、 multi-planer reformation (MPR), CT virtual endoscopy (CTVE) and CT volume rendering (CTVR) before surgery and after reconstruction of ossicular chain. Results HRCT (axis and coronal position) can better demonstrate tympanic cavity and soft tissue lesion in it, but poorly demonstrate ossicles, implanted prosthesis in the operation, and has difficulty in showing the whole ossicular chain. MPR could demonstrate each ossicle and the ossicular chain on the same plane. The CTVE showed the 3 -D imagine of the ossicular chain but wasn't quite true to the original. Because of the shaded surface display in the virtual technology of computer. The CTVR, adopting the volume rendering technology, showed the true shape of the ossicular chain when the unwanted soft tissue and hone were cut down especially to the reconstructed ossicular chain. Conclusion The diagnosis of ossicular chain of the modem CT technology should combine the HRCT with MPR, CTVR and CTVE. The CTVR 3-D reconstruction may be better than CTVE.关键词
