Using transplantation of free muscle with microneurovascular anastomosis for 46 cases of late facial paralysis, we selected M. latissimus dorsi as neurovascularized muscle bundle graft in 28 of them. This was not only an operation for facial dynamic reconstruction but also a new method for reinnervation of oral and ocular sphincter. After operation all of them revealed symmetry with voluntary motions. The results were satisfactory. The indications for surgical treatment, the procedure, and the management after the treatment were discussed in details. The importance of reeducation of the regenerating nerve and the necessity of twostaged operation were also discussed.
