How can I find a specialist in tuberous breast correction?

Thank you for the question.  It is an important one: selection of your plastic surgeon will be the most important decision you make when it comes to achieving an outcome that you will be pleased with.
Generally I suggest that patients start with the American or your national Society of Plastic Surgery and/or the Aesthetic Society of Plastic Surgery to obtain a list of well experienced board-certified plastic surgeons.
Then, I would suggest you visit a few surgeons whose practices concentrate on aesthetic surgery. 
***Ask to see lots of examples of their work and preferably speak/see patients who have had similar procedures done.  Ultimately it will be important that you feel comfortable that your plastic surgeon have a significant/demonstrable experience consistently achieving the types of outcomes you will be pleased with.   
Besides appropriate training and experience (and certification by the American Board of plastic surgery), looking at before/after photographs (and  preferably talking to previous patients) can be very helpful in this selection process.
 Basically, patients should look at the overall "quality" of the outcomes achieved;  in other words, it will be important that patients see lots of examples of outcomes that they would be pleased with.  In doing so patients will be able to get an idea of each  plastic surgeon's "aesthetic sensibilities".Generally, correction of tuberous breast anomalies involves breast augmentation with areola reduction/mastopexy procedure. The distance from the inframammary fold is increased (to create a more rounded out appearance). Proper implant positioning improves the distance (cleavage) between the breasts. The areola reduction helps to treat the pointed and "puffy" appearance of the areola.I hope this helps. Best wishes.

Hello Vancouver! Tuberous breasts are hard to correct. In my 24 years of experience of an exclusive Breast Surgery practice a periarolar lift with scoring of the gland or medial pedicle reduction with dual plane augmentation is your best solution. Best of luck! JP Riou, MD
