Multi-slice Spiral CT Study of Traumatic Facial Palsy / 实用放射学杂志

ABSTRACT

Objective To explore the applied value of multi-slice spiral CT(MSCT) scan in the traumatic facial palsy.Methods 41 cases of traumatic facial palsy were scanned using MSCT,the MPR of interseted region of temporal bone and curved planar reconstruction(CPR) images were performed on Philips Mx8000 MSCT work station.The types,locations and course of the temporal bone fracture and the involving features of the external auditory canal,middle ear,inner ear were observed.Results 39 cases of the 41 patients had temporal fracture in different location.34 cases were longitudinal fracture,2 were transverse fracture and 2 were mixed fracture.The facial nerve canals were involved in 21 cases.Conclusion MSCT and the reformation images can help to study the facial nerve canal in the traumatic patients.It is important to use the MPR and CPR in the traumatic facial palsy.
