Gynecomastia Surgery vs. FTM breast reduction?

Hello, and thank you for your question. (Keep in mind that an in-person consultation is necessary for the best advice.) The procedures you have described have different indications and are for different patient populations---even though they are somewhat similar. Gynecomastia surgery is more technically demanding because it is done through smaller incisions---resulting in limited visibility and longer time in the operating room. FTM surgery typically is done through larger incisions which reduces the amount of time spent in the operating room---translating into lower costs. There are certainly other factors that play a role in how those plastic surgeons set their fees, but they are beyond the scope of this Q&A. 
Anyway, if you decide to pursue surgery it’s very important that you find a surgeon whom you are comfortable with and trust and who evaluates you in-person and tailors an individualized treatment plan for you and your aesthetic goals. Best of luck!

Not sure why you are getting different price quotes.    As I can't see any pictures it is hard to give you adviece.    The FTM is usually much more expensive then just liposuction for gynecosmastia.  Best to see a board certified plastic surgeon.
