[One-stage extralong neurovascular pedicled segmental muscle flap transfer in the treatment of late facial paralysis].

One-stage extralong neurovascular pedicled segmental muscle flap transfer was used in the treatment of late facial paralysis in 10 cases. The length of ultralong neurovascular pedicle (14-17.5 cm) was longer than that of normal muscle flap (3.5-8 cm), since the former included dorsal thoracic artery, vein and nerve with their branches and ending segments as a whole. Compared with the current operations, the design of this operation can omit the cross-facial nerve graft in the first stage of operation and prevent the possible failure of additional nerve anastomosis. Ten cases were followed up for more than a year. All of them revealed voluntary movement of the transferred muscle flap with satisfactory results.
