Abstract：Objective To investigate the efficacy of middle cranial fossa approach facial nerve decompression in treating facial paralysis after longitudinal fracture of the temporal bone. Methods Clinical data, operative techniques and outcomes in 5 patients with peripheral facial paralysis after longitudinal fracture of the temporal bone were re-viewed. Results The site of facial nerve injury was located to the geniculate ganglion area in 4 cases, in which the facial nerve was decompressed via the middle cranial fossa approach alone. The site of facial nerve injury was located to both the geniculate ganglion and tympanic segment, and was decompressed by a combined middle cranial fossa and auditory canal approach. House-Brackmann classification before and after surgery was compared to evaluate treatment efficacy. Pre-operative H-B grading was V in,3 cases andⅣin 2 cases. At 1-2 years postoperative, H-B grading wasⅡin 2 cas-es an I in 3 cases. Conclusion Facial nerve injury caused by longitudinal fracture of the temporal bone occurs more of-ten in the geniculate ganglion area. Facial nerve decompression vis the middle cranial fossa is an effective management for traumatic facial paralysis when injury site involves the geniculate ganglion area.
