One-stage reconstruction of established facial paralysis using a rectus abdominis muscle transfer.
A free vascularized rectus abdominis muscle graft with a long motor nerve was used for reconstruction of unilateral established facial paralysis in one stage. Regarding the procedure, the pedicle vessels were anastomosed to the recipient vessels in the ipsilateral face, and the motor nerve of the muscle was sutured to the contralateral facial nerve. The advantages of using the rectus abdominis muscle are as follows: (1) the muscle is very thin, not bulky, (2) the muscle can be split easily to reduce the volume, (3) the intercostal nerve is long enough (more than 20 cm) to reach the contralateral facial nerve for suturing, (4) the pedicle vessels are large and long, (5) it is possible to carry out simultaneous operations with two teams, and (6) the donor-site morbidity is minimal. The disadvantages of this method are that complicated surgical dissection is required to obtain a motor nerve and that a postoperative abdominal hernia may occur.
