Objective: To evaluate a modified technique of sternocleidomastoid muscle transposition for the dynamic reanimation of the chronic facial paralysis.
Methods: Both of the sternal and cleidus extremities of the sternocleidomastoid muscle were elevated from their bony attachment. The mastoid extremity was left in the place as a pedicle for the blood supply. The muscle stripes were then transposed into the face through the tunnel under the skin and the ends were sutured to the opposite orbicularis oris muscle of the upper and lower lips to correct the deformity of the mouth and nose.
Results: Forty-four patients with the chronic facial paralysis had successfully been treated by using the above-mentioned technique. The static asymmetry of mouth corner and the independent oral activity of the paralyzed side were corrected without any failure. With the follow-ups up to 3 years, the results were satisfied.
Conclusions: The chronic facial paralysis with the deformity of the mouth and nose could be corrected with the sternocleidomastoid muscle transposition technique. A part expression of the mouth could also be achieved.
