Is this a troll? When you refer to "maxillofacial surgeons," I'm assuming you mean the specialty "oral and maxillofacial surgery," because plastics, ENT, and OMFS are all maxillofacial surgeons. Each of these specialties operates on the craniofacial skeleton, so because one specialty has the word "maxillofacial" in it does not mean that they are the most well-trained facial surgeon. ENT would really be referred to as "Otorhinolaryngology - Head and Neck Surgery and Facial Plastic and Reconstructive Surgery." ENT is much easier to say, though. It would make more sense to me if you were to say "craniofacial surgeons," because craniofacial surgery is a subset of more specialized training within plastic surgery, and in this case I would say yes, craniofacial surgeons would have better training (because they have more training). With respect to facial cosmetic and reconstructive surgery, I'm not quite sure where you've obtained the impression that OMFS surgeons are more well-trained. To the contrary, OMFS requires the least training of all the three fields I mentioned previously (Plastics is 6-8 years, ENT Facial plastics is at least 6 years, and OMFS is 4 years), and by far has the least case load for cosmetic cases at any program I have seen. I've heard of some OMS trying to get into rhinoplasty, but I don't know of any OMS residents training on facelifts, blephs, or any other cosmetic cases, they certainly don't do them where I train. In general, the majority of OMFS surgeons are going to 1) extract wisdom teeth (that's where the money is) or 2) fix mandibles (they also do a lot of implants). The only thing OMFS does that ENT does not is mandibular and maxillary distraction, but there are very few of these cases that are actually performed, plastic surgery trains to do these as well. In fact, the biggest name craniofacial surgeon around my area is an ENT who then did a PRS fellowship, which makes a lot of sense. There are several big name guys who have OMS backgrounds but go on to further their training by doing PRS fellowships, after which they tend to work on big head and neck reconstructions like plastics and ENT, but if you were to poll pretty much anyone, they would rather their facelift, rhinoplasty, or blepharoplasty be done by a plastic surgeon or facial plastic surgeon rather than a general OMFS.
So to answer your question "in ten years will maxillofacial surgeons overtake plastics as the go to guy making plastic surgeons almost 'obsolete,'" no this will never happen. OMFS surgeons will stick to wisdom teeth and mandibles, and plastic surgeons will stick to plastic surgery. If that paradigm shifts, then I'm going to start taking out wisdom teeth.
