Buried sutures can create minor one problems after breast augmentation and are not infections.
It looks as though you may be necessitating a small subcutaneous suture. This is managed by wound toilet. Your surgeon instruct you on the specifics.
Hi. This looks like a superficial stitch abscess that will probably heal just fine, but I would still advise you to rather contact your primary surgeon for opinion and any management deemed appropriate.
Thank you for your question and providing a photo. Based on the photo provided I believe this will heal fine and not cause any problems. This appears to be a stitch abscess which does not require any more than locl wound care. I would recommend you keep it clean and apply antibiotic ointment. Best of luck
Thanks for the question and photo. It looks like you had a small area of opening where the suture knot was located. This should heal uneventfully, but if there is any question, I recommend that you visit your surgeon. Best Regards.
