I generally tell all patients to expect some minor wound healing issues at the top and bottom of the vertical incision after a breast with with implants. They generally are extremely small in nature but sometimes can get quite large especially in smokers At this point, I assume your plastic surgeon is actively involved. However, this is likely a situation that would only require a topical antibiotic cream and extra healing time. In the end, it should look very good.
It's not uncommon for absorbable sutures to work their way to the surface of the wound when patients undergo breast augmentation combined with breast lift surgery. When this happens, it's not unusual for small superficial separations of the wound to occur. This problem is especially common at the junction between the areola and the vertical incision.
When this situation arises, wounds are best managed with dressing changes. Occasionally antibiotics are necessary if the separation is associated with infection. The vast majority of these wounds heal nicely and secondary surgery is rarely indicated.
When this type of separation occurs, it's important to consult your plastic surgeon. Your surgeon should be able to develop a treatment plan that addresses your concerns.
Hole in breast lift incision may be a suture spit
I cannot tell without an in person examination but from your photograph it appears there is a small open area with red dermis beneath but the superficial skin cells missing. Most commonly this happens when a deep suture has spit and been rejected by your skin. However it is important that you see her plastic surgeon for an exam.
Breast Lift Healing
This can be very normal. Based on the photos, it does not look infected, but check with your surgeon to be sure. Sometimes a stitch is trying to work it's way to the surface. Sometimes it is just a little skin opening. It appears small and your surgeon has probably advised you how to care for it. It is best to keep it clean by showering every day and washing the area, but avoid soaking and swimming for at least 3 weeks after complete closure. Your surgeon may ask you to place a gauze over the area. It should heal fine over time.
