Thirty-four patients with facial palsy due to skull trauma have been treated surgically since 1967. The best results were obtained when the operation was performed within two to three weeks of the onset of palsy. If electromyographic and nerve-excitability test results change for the worse we must resort to operative intervention without hesitation. A noninfective postoperative process is important for obtaining the best surgical results. For this end special care must be taken in the preservation of the posterior bony wall during the operation. Bony dehiscence in the fallopian canal near the oval window may play an important role as well as hemorrhage in the fallopian canal or circulatory disturbance in the nerve itself in the occurrence of facial palsy in which no fracture line is observed.
