Treating later facial nerve palsy with the method of combining free graft of de-nerve short extensor muscle of toe with the technique of inducted undermined suture

Objective To explore a more effective operative method for later facial nerve palsy. Methods A synthetically operative method of combining free graft of short extensor of toe with the technique of undermined inducted suture was used in 432 cases of later facial nerve palsy. Results 82% of 432 cases acquired satisfactory effect that consisted of static symmetry and dynamic rough symmetry in facial expression. 12% cases only acquired static symmetry in facial expression but the dynamic symmetry were insufficient. Unsatisfactory results were occurred in 6% cases as both the static and dynamic symmetry of their facial expression were insufficient, which acquired preferable results 2 another suspending operation 8 to 12 months later. 4 cases got post operation infection, through cases happeel in foot and 2 in face. All of them were cured by the treatment of drain and antibiotic in 3 weeks. 46% cases were followed up by further consultation or telephone. The longest followed up was period 12 years, while the shortest was 1 year, and the average was 28 months. 93% patiewts were satisfactory with the results, and 7% patients thought that their facial expression symmetry were insufficient though their facial abnormality were improved obviously. Conclusions The synthetically operative method of combining free graft of short extensor of toe with the technique of undermined inducted suture was an effective method for later facial nerve palsy, and most of the patients could acquired satisfactory results. This operative method is good for popularize because of its simple operation, slight tissue injury and fews complication post-operation.
