Is an ENT just as qualified to do rhinoplasty as a board certified cosmetic surgeon?

A  board certified ENT doctor can address sinus and breathing related issues. A board-certified facial plastic surgeon has additional qualifications and training to performing rhinoplasty, which is one of the most difficult procedures to perform  in the entire field of cosmetic surgery. A Double board certified ENT/ facial plastic surgeon can also address both functional and cosmetic nasal surgery.

This is a great question. Thank you for sharing. When patients are considering having any facial plastic procedure (especially rhinoplasty) a surgeon’s board certification is one of the most important things to consider. Any physician can call themselves a "cosmetic surgeon", "aesthetic surgeon", etc. However, there are only three certifying boards generally accepted by the medical community that recognize a surgeon as qualified to perform comprehensive facial plastic surgery: The American Board of Facial Plastic and Reconstructive Surgery (ABFPRS), The American Board of Plastic Surgery (ABPS) and The American Board of Otolaryngology, or ENT (ABOto). While the listed specialties are all recognized as having the appropriate training to perform rhinoplasty, keep in mind that board certification should not be the only qualification you should look at when choosing a rhinoplasty surgeon. Experience is also very important. Rhinoplasty is the most difficult procedure performed by these specialists. The most experienced and successful rhinoplasty surgeons dedicate a large proportion of their practices to rhinoplasty and they perform the operation frequently.  You should also have the opportunity to review a collection of before and after photographs (either on the website, RealSelf, or for private consultation). These photos will allow you to assess the surgeon's experience, results, types of patients and noses, as well as case volume. With all of that being said the answer your question is "Maybe." Since you have both functional nasal/sinus issues as well as aesthetic concerns, an otolaryngologist (ENT), or Facial Plastic Surgeon, would likely have the appropriate 'training' to address both the functional and aesthetic concerns. But, you need to make sure the additional criteria (listed above) are also met. 

Both plastic surgeons and ENT surgeons may be qualified for nose surgery but sinus problems are usually addressed by ENT surgeons, not all of whom do rhinoplasty. Start with a sinus doctor then ask about a surgeon for the cosmetic issues.
