I don't understand what a fellowship has to do with this issue. If you've done the required procedures in residency, you should be able to perform them...period. If not, then a fellowship is a good idea. This is true for any procedures...cosmetics, orthognathics, clefts, etc. This should also be true for OMFS/ENT and whoever else.
The people who claim "only fellowship-trained OMFS's should do cosmetic procedures" are ignoring the cosmetic procedures already done in routine OMFS residency. I agree that the amount is variable, but this is surprisingly true for general plastics residencies as well.
Pikevillemedstudent, I am guessing you rotated with Louisville's OMFS department. While they have some highly-respected faculty in the AO/ASIF world, Brian & George have no interest in cosmetics. That program is definately a "bread-n-butter" program with a pretty narrow scope. If you're at Lexington then the same is true but to a lesser extent.
