Objective To investigate the result of free vascular transplantation of denervated extensor digitorum brevis and extensor hallusis brevisfor the treatment of late facial paralysis. Methods From April 2003 to April 2005, 26 cases of facial paralyces were treated by transplantation of denervated extensor digitorum brevis and extensor hallusis brevis. During operation, the ends of the tendons were fixed at ala nasi, middle point of nasal labial fold,oral commisure and chin; the muscle belly were put around the masseter nerveto correct the nasal and oral deformity, microsurgery was applied to anastomosethe tarsus lateral vessels to the superficial temporalis vessels or the facial vessels. The result of the operation was evaluated by the Standard of Douglas Harrison and the Paresis Assessment scoring system of Stennert. Results The static appearance was satisfactory in 26 cases after operation, the bilateral oral commisure was symmetry and the dynamic appearance was greatly improved 6 months after operation. Among the 23 cases whose disease history was above 2 years，all could smile naturally and show their teeth symmetrically except 1 case whocould only move the oral commissure. Among the 3 cases whose disease history was less than 2 years, one could smile naturally and show his teeth symmetrically, one could smile but could not show his teeth symmetrically, another could move oral commissure but have no motion appearance. The result was evaluated as“” according to Standard of Douglas Harrison, accounting for 88% (23/26). Evaluated according to the Paresis Assessment scoring system of Stenert, the difference before operation and after operation was more than 5, accounting for 86% (22/26). Conclusion The free vascular transplantation of denervated extensor digitorum brevis and extensor halluces brevis can reconstruct the oral appearance for the treatment of late facial paralysis.
