Breast Reduction/lift but open areas underneath breast not healing (Photo)

Dear Lisa Austin, Open areas that have some drainage after a breast reduction procedure are actually very common. It seems your surgeon is treating this issue appropriately. Continue following their instructions and if you any more concerns be sure to communicate with your operating surgeon. I wish you the best of luck !

Unfortunately, delayed healing after breast reduction is very common.  You should stick with your surgeon and follow the advice given. 
It is not possible to give great advice from a couple of photos on the internet.  It does not allow evaluation of the overall picture.
In genera,l good wound care for an open wound such as these would involve keeping the areas lightly moist and not allowing them to dry completely.  This can be accomplished with saline moistened gauze (which is what a assume you were instructed to do).  It can also be accomplished with Vaseline, bacitracin or a large number of other types of dressings.
Stick with your surgeon.  Be seen in the office as often as you need to feel comfortable.  I often see patients with slow healing wounds weekly to direct care and modify as needed.  And sometimes I see them just to hold their hand and give reassurance that these wounds will heal.
In the end, this diversion will seem like nothing once you are healed and have permanent relief of your back and shoulder pain.

Dear Ms. Austin,Thank you for your pictures. This happens more than you realize. It sounds like your plastic surgeon is right on top of it. I would recommend continue to follow his or her advice and this will heal.Best wishes,Earl Stephenson, Jr., M.D., DDS, FACS

At this stage of recovery from breast reduction, it is not uncommon as the internal sutures start to dissolve for the body, rather than dissolve the stitches into the body, to push them out through the skin. It is especially common at the point where 3 incisions come together. It can look pretty scary, so your concern is understandable. Treatment is local wound care, as your surgeon advised, and occasionally antibiotics. This usually resolves with minimal effect on your ultimate scar. Continue close follow up with your board certified plastic surgeon.

It is not unusual to have some wound healing issues at the joins of the incisions. As long as there is no underlying fat necrosis / infection / seroma this should heal relatively quickly. It sounds like your PS is treating you appropriately and this should all heal.
