Abstract

Abstract:

Objective

To evaluate the effiency of descending hypoglossal branch-facial nerve anastomosis for the severe facial palsy after acoustic neuroma surgery.

Methods

The clinical data of 6 patients (2 males, 4 females, average age 45.5 years old) underwent descending hypoglossal branch-facial nerve anastomosis for treatment of unilateral facial palsy was analyzed retrospectively. All patients previously had undergone resection of an acoustic neuroma. House-Brackman grading system was used to assess the pre-, post-operative and follow up facial nerve function status. The patients were followed up for at least 12 months.

Results

According to the House-Brackman facial nerve function evaluation system, 1 case is Ⅱ grade, 2 cases are grade Ⅲ, 2 cases are grade IV, 1 case is Ⅴ grade. Patients with facial sensations were improved compared with preoperative. In the 6 patients, 5 patients had satisfactory facial symmetry, and one patient could close the eyelid, and the eye crack almost disappeared. All patients had no paralysis of the ipsilateral lingual muscle and no obvious pronunciation and swallowing dysfunction.

Conclusion

Descending hypoglossal branch-facial nerve anastomosis is effective for facial reanimation.
