Hi,
Maxillofacial is a medical doctor, and also a dentist. (maybe not in that order ) Some may believe (I am inclined to agree) that one doctorate is enough to contend with (specialise in). By all means combine the two if a multi skill environment is an intention. But we are not talking electronic/electrics/mechanics here. Its fixing lives, not constructing materials. Should the neurologist become a neuro/cosmetic surgeon with a diploma in chidbirth. We can extend accolades to silver, gold and platinum, solid intent fortitude and Man United will always prevail.
