Abstract:
Objective To explore the application value of 256-slice high resolution CT(HRCT)and reconstuction technique in the preoperative assessment of ossicular chain trauma.Methods 106 cases of temporal bone trauma were scanned using 256-slice HRCT,38 cases of ossicular chain trauma were collected.The multi-planar reformaition(MPR),curved plannar reformation(CPR) and three-dimensional volume rendering reformation (3D VR)of the ossicular chain were performed on Philips work station.The locations, types and the involving structures were analyzed,then these cases were followed up.The display rates of AX,MPR,CPR,3D VR were evaluated.Results Among 106 cases of temporal bone trauma,38 cases(76 ears)were found ossicular chain trauma,in which there were 43 ears of ossicular dislocation,22 ears incudomalleolar joint separation,6 ears incudomalleolar and incudostapedial joint separation,3 ears incudostapedial joint separation,11 ears translocation of the ossicles,1 ear stapediovestibular dislocation;4 ears ossicular fractures,2 ears fracture of the malleus,1 ear fracture of the incus,1 ear fracture of the stapes.Among 38 cases,11 cases underwent surgery,and the surgical results were consistent with CT findings.The display rates of AX,MPR,CPR,3D VR were 97.87％,100％, 97.87％,82.98％ respectively.Conclusion 256-slice HRCT and reconstuction technique can clearly reveal the whole structure of ossicular chain trauma,which are effective methods for diagonsis of ossicular chain trauma before surgery.
