Tummy tuck drain holes, 9 months post op, is it normal to have such deep indentations.

Thanks for your question. Without a photo or exam it is hard to say, but normally drain exit sites aren't very noticeable after the first 3-6 months. It could be that these areas can be revised in the office. Best of Luck!

are unpredictable and what you have is not unexpected.  You should discuss revising those with your surgeon as all surgeons should want the best outcomes for their patients and indented scars do not fit that goal.
