Hole in tummy tuck incision (photo)

The most likely cause of the opening is a deep stitch that needs to be removed by your surgeon. Once the stitch is removed in the office the opening will close.

Thank you for sharing your question and photograph.  This appears to be a localized area of irritation and infection caused by a retained suture that should be removed in your doctors office to allow this to fully heal.  It should not materially affect your incision's long term appearance.  Hope this helps!

     It is likely that the cause of your hole is a buried suture.  Let your plastic surgeon know and he/she can address it in their office.
