How can I find a specialist in tuberous breast correction?

An imbalance or assymetry between the size and shape of
each breast is very common in the majority of women. Underdevelopment or incomplete development of the
breast that usually occurs during puberty and affects breast development is
generally the most common reason for these irregularities.  
Many women who have
tuberous breast deformity wish to bring their breasts into a more symmetrical
proportion while also addressing other irregularities caused by the condition. You
need to seek the advice of a Board Certified Plastic Surgeon with extensive
experience correcting tuberous breasts. By using differential breast implants
to create an equal volume, and by lowering the bra crease and minimizing
puffiness around the nipple, a skilled surgeon can create a symmetrical,
natural result. Every breast is different and you will need a customized surgical
plan to meet your desired result.

There is "herniation" of breast tissue into the nipple/areolar complex, making the breast appear stretched into a "tube". The correction consists of a mastopexy to tighten the skin envelope, possible placement of a prosthesis submuscular and also possible use of Alloderm graft to support the tissue.
Postop, it is imperative to wear support for an extended period of time, including steristrips on the areolar scars and good support bras!
Concerning, the asymmetry, I probably would do the same procedure on the opposite side to get as much symmetry as possible.

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.
