Hypoglossal-facial anastomosis after facial nerve transection

The facial nerve reconstruction after facial nerve transection is a hard mission to the clinician. All of the patients who suffer from severe facial paralysis want to have their original facial function even if they had tremendous aggressive disease or surgery. One of the surgical technique for facial reconstruction after facial nerve transection is the hypoglossal-facial anastomosis. This surgical technique provides favorable facial function even after aggressive tumor surgery. But this surgical technique also has a critical defects on tongue movement. The use of hypoglossal nerve could induce other problem in terms of quality of life including dis-articulation, leakage on oral feeding and/or biting of their tongue. Another variation techniques rather than classical XII-VII could be recommended for minimizing the hemi-tongue paralysis. Split XII-VII technique, Jump graft XII-VII technique, ansa-facial anastomosis are known to be variation technique that have been developed for reducing such a complication after surgery. In this paper, this author introduces details of surgical techniques and results for maximize the facial function and minimize the hemi-tongue paralysis.
