Small Hole Like Wound Under Breast 1 Month Post Op; What Should I Do?

Thank you for the question.

This small wound that you are experiencing is not infrequently seen after breast lifting or breast reduction surgery. Generally, these areas go on to heal without long-term sequelae. I am glad that you are following up closely with your plastic surgeon who can rule out the presence of a long-term dissolvable stitch that may slow down healing. If an implant is present,  exposure should be avoided/prevented.

I hope this helps.

At one month post-op, the rest of your incision have healed pretty durably, so things aren't going to "fall apart" or cause a problem, UNLESS this tiny hole is allowed to become a portal for infection entering the still-healing tissues beneath the opening.

This is most likely an area of incomplete healing that could represent a dissolving stitch site, or just an area that was irritated open by your underwire. Keep it clean and protected by a dab of Bacitracin ointment (double or triple antibiotic is OK, but double or triple your chance for an allergic reaction, which looks like an infection) and a Band-Aid. Change as needed but watch so you don't cause blisters from the bandage adhesive on your delicate breast skin. (This would be an example of the treatment causing a worse problem than the initial problem!) BTW, I allow my breast surgery patients to wear an underwire bra after 3 weeks IF everything is healed completely.

This tiny spot should heal from the inside out in a few days. You can shower and gently wash this area. If there is any increase of pain, redness, swelling, or purulent (pus) drainage, call your doctor. I agree with your suggestion to avoid further irritation from your bra. The final scar should be smaller that the opening, since scars contract. Best wishes!

Most likely the underwire in the bra rubbed against the area most likely to have wound healing problems after a breast lift - namely the junction of the "T" under the breast.  This is usually treated very conservatively, with dressing changes, and goes on to heal all by itself.  I suggest you be evaluated by your Plastic Surgeon and have him/her prescribe the appropriate treatment.
