Pinhole and seroma. Is my wound going to heal? (Photo)

Dear MonzeRivadeneyra,
This type of wound is not uncommon after breast lift. It is usually caused by spitting suture. I would suggest you to consult your plastic surgeon, follow your surgeon's instructions and keep your wound clean and covered. It can take few weeks or months for wound to fully heal.

Thanks for the question. If it is a small hole, not leaking, proven not to have infection and with good quality surrounding skin as it appears in the photo, then I would certainly consider exploring and excising the hole (sinus) under local anaesthetic. Best wishes,

Continue to see your surgeon regularly. If the wound is healing it is reasonable to continue with the plan. However, if static after a number of months it may be beneficial to debride and close the wound.

Hi and welcome to our forum!
Delayed healing after breast augmentation and lift is not uncommon. It can be caused by poor blood supply, infection, or fluid collection (such as seroma). 
Cultures have proven negative and the seroma has abated. 
If there signs of continuing improvement with conservative care and if there is no implant exposure, I would continue conservatism. If the situation has become static, one may consider debridement and secondary closure although it carries a risk of infection. If the implant is exposed, it may require temporary removal / later replacement.
Continue close followup care with your plastic surgeon.
Best wishes...

I'm sorry that you are experiencing these issues after your breast augmentation.  You are doing the right things by following proper wound care and keeping in touch with your surgeon.  These wounds can heal slowly, but with proper treatment they should heal completely.  I encourage you to continue to follow the advice of your surgeon and report any changes.
