Dear Finally2015sept, Thank you for your clinical post. You have not mentioned how far post-operatively you are. However, from the photos provided you appear to be in the first few weeks following the surgery. It doesn’t appear that your umbilicus is in fact splitting. The discolouration may be slight venous compromise and keeping the area clean with peroxide, topical antibiotic and a Band-Aid until you visit with your physician would be all that is required. If you begin to see evolution in ongoing discolouration, more blueness or even black colour, I would page your operative physician’s paging services, as it may be a soft tissue profusion emergency. I doubt this will happen. It appears that you have some early post-tummy tuck wound healing around the belly button restoration and you should end up with a great result.
