I recently had a small hole develop on my incision line. Any idea what's happening with this hole? (Photo)

Thank you for your question and photos.  I would recommend that you visit with your plastic surgeon who can better examine you in person and discuss what to do.  It is hard to see how deep the hole is from the photo.  It could be something a simple as a suture spitting out or it could be a communication that runs deeper to the implant.  

Thank you for your question, and photographs.  I see the hole you are referring to, and this may be as simple as a suture that worked its way out of your skin, leaving a small wound that your body will fill in with time, or you may have had a localized infection, termed a stitch abscess, that caused the wound to separate. The important thing is to rule out any communication with deeper tissues, namely your implants.  I recommend you speak with your surgeon so that they can perform an in-person examination and offer you care instructions until this hole has resolved. 

It looks to me like you may have developed a "stitch abscess" - a totally normal situation where one of the deeper suture knots from the incision works its way out the skin.  It should be fine and resolve on its own.  I recommend discussing this with your surgeon. Certainly, find your surgeon more urgently if you have developed significant redness, pain, drainage or are having fevers or chills.It is critical that you seek the advice of a surgeon who is certified by the American Board of plastic surgery.I wish you the best,Dr. Gabbay
