Facial nerve management in cranial base surgery.
This study reviewed 124 patients who required facial nerve manipulation during cranial base surgery. Most of them underwent only nerve displacement or selective transection for improved surgical access to the cranial base (70 and 34, respectively). Fourteen patients had the facial nerve resected for oncologic reasons and repaired with primary nerve grafting. Most patients regained quite satisfactory facial function with quality correlating with the degree of nerve injury. Six patients had facial nerve resected as part of oncologic palliation and had the facial deficit rehabilitated with regional tissue. A correlation between preoperative facial nerve weakness and the quality of nerve graft function was not found. An oncologic correlation, however, is suggested (patients with preoperative weakness had less favorable prognosis). Overall, patients who require facial nerve resection for oncologic reasons do not do as well as those with normal preoperative function.
