Difference Between Facial Plastic Surgeon or Plastic Surgeon and an ENT or Otolaryngologist?

Facial Plastic surgeons are generally ENT surgeons who want to specialize in cosmetic surgery, most of the time on the face, but many also migrate south and will do such things as breast and body work.  There is no doubt that there is a turf war over which specialty is better qualified to perform which particular procedure.  When it  comes to rhinoplasty specifically, both specialties have training that enables them to perform this procedure.  I would base my choice on selecting a surgeon who has significant experience with rhinoplasty and one that you have been able to see many examples of their work and that you like the work they do.  When it comes to breast work,  however, I would definitely stick with a fully trained plastic surgeon.

An otolaryngologist/head & neck surgeon is trained to operate on all structures in the head and neck excluding brains, spines, and eyeballs (in a nutshell). 25% of the board certification exam for otolaryngologists covers facial plastic and reconstructive surgery. The term "ENT" is an abbreviation for an otolaryngologist.

Facial plastic & reconstructive surgeons can become board certified as such in one of two ways.  First, they can complete an accredited fellowship focusing in FPRS only for at least one year following completion of EITHER an "ENT" or plastic surgery residency. They must then complete an oral and written board exam and submit a case log of at least 1 1/2 years of procedures performed to establish competence. Alternatively, board-certified "ENTs" or plastic surgeons that do not complete a fellowship must submit a more extensive case log and pass the same exams. 

Hope that helps.
