Paralysis of the mandibular branch of the facial nerve.
A direct and simple operation of transfer of the anterior belly of the digastric muscle with its attached tendon is presented. It was carried out in 36 patients, with three minor complications. It has proved effective in paralysis of the mandibular division of the facial nerve as a primary or secondary procedure. In ablative resections where this branch of the nerve is intentionally sacrificed, it is advised to do the muscle and tendon transfer as part of the primary operation. In aesthetic operations or where the status of the nerve (post-operatively) is not specifically know, it is advised to wait for spontaneous return for an interval of 3 to 6 months. If the improvement is not satisfactory, then this technique may be considered.
