My son has only 4 more Radiation sessions but my question has to do with something his doctor (Oral & Maxillofacial Surgeon) told us immediately after surgery for removal of 1/6 of his tongue. He said that the tongue regenerates and that it takes about a year for it to grow back. I've searched on this site and also on google but find nothing to support this although I did find research done with snakes and rats concerning tongue regeneration. Has anyone heard of this or perhaps experienced tongue regeneration? I was wondering if it depended on how much of the tongue is removed.
