Is you naval supposed to close after six months?
Contraction of the circular umbilical area occur after full TT. Best to consider a minor operation to enlarge the area. But understand scares can occur...
Is your belly button supposed to close?
It is unfortunate , but you have hypertrophic scarring and will need a revision. However, you might want to try injections of kenalog first. You have many great plastic surgeons there in New Orleans where I used to live. Off the top of my head I would recommend Dr. Cynthia Mizgala who is my former partner and a brilliant and very nice doctor.
Closing bellybutton after tummy tuck
It's hard to tell from your photo but could this be a keloid or hypertrophic scar. If it is it would've close gradually. Talk to your doctor to see if they think it could be a keloid and if it is sometimes a steroid injection may decrease the scar tissue and allowed to open up.
Thank you for your patience. I think your results look very good. It appears that your belly button does have some stenosis (moderate closing).
A belly button that closes after a tummy tuck can be fixed. A revision would be needed and one of several belly button revision surgeries can be performed. Often, the scarred belly button top is removed and the remainder of the stalk is sutured to the surrounding skin.
All the best,
Dr. Remus Repta
