Long-term results of spinal accessory nerve-facial nerve anastomosis.
A number of methods have been developed to reduce the cosmetic and functional disability resulting from facial nerve loss. It has often been suggested that the major trunk of the spinal accessory nerve should not be sacrificed for providing dynamic facial function because of shoulder disability and pain. A review of Mayo Clinic records has revealed that, between the years of 1975 and 1983, 25 patients underwent spinal accessory nerve-facial nerve anastomosis using the major division (branch to the trapezius muscle) of the spinal accessory nerve. There were 11 males and 14 females, ranging in age from 16 to 60 years (mean 41 years). The interval between facial nerve loss and anastomosis was 1 week to 34 months (mean 4.62 months). The duration of follow-up study ranged from 7 to 15 years (mean 10.8 years). Twenty patients had no complaints or symptoms related to their shoulder or arm at the time of this review and no patient had significant shoulder morbidity. The facial function achieved was "minimal" in five cases, "moderate" in six, and good to excellent in 14. Most patients appeared to benefit significantly from the spinal accessory nerve-facial nerve anastomosis. The morbidity of the procedure seemed quite minimal even in the young and active. The authors continue to believe that the spinal accessory nerve-facial nerve anastomosis, even when using the major trunk of the spinal accessory nerve, is a very useful and beneficial procedure.
