Surgical treatment of facial paralysis resulted from temporal bone fractures

Aim To investigate the treatment and operative opportunity of facial paralysis resulted from temporal bone fractures.Methods Facial nerve decompression was carried out in 7 cases of facial paralysis resulted from temporal bone fractures,of which 3 were treated with transmiddle cranial fossa approach,2 with transmastoid approach and 2 with trans-mastoid and middle cranial fossa approach.Results During operation,injuries to the labyrinthine segment of facial nerve and geniculate ganglion were found in 4 cases,tympanic segment injuries in 3.House-Brackmann(H-B)system was used to evaluate the recovery of facial nerve function.A follow up for 6 months showed that 3 cases reached grade Ⅰ of H-B,2 cases grade Ⅱand 2 cases grade Ⅲ.Conclusion As for cases with facial paralysis resulted from temporal bone fractures,the extent and position of facial nerve trauma should be early confirmed.Complete facial palsy facial nerve decompression should be performed on the basis of position of facial nerve trauma determined preoperatively.Incomplete facial palsy urn to medical treatment and surgery treatment should be performed as nonresponder.
