How many brain surgeons in the US?

In short around there are only about 6-7000 plastic surgeons in the US. However, this is a very difficult question to answer. Many physicians in other fields and even non-physicians may identify themselves as "cosmetic surgeons" and perform cosmetic procedures. Other related specialities (namely otolargyngology, ophthomology, oral-maxillofacial surgeons) also have subspecialties which focus on plastic procedures. They will usually identify themselves as "facial plastic" or "occuloplastic" surgeons. If you include all of these physicians as well, there are probably around 60,000.
