Tummy Tuck Revision to Fix Belly Button and Bulge?

Based on your pictures revisionary surgery or more accurately abdominal wall reconstruction is necessary. This would likely involve repair of any diastasis recti or hernia present. Further skin/adipose  tissue excision of the flank and back areas may be necessary to improve contour and eliminate “dog ears".

Seek consultation with a well-trained experienced board-certified plastic surgeon. Best wishes.

Have you discussed this with your surgeon(s)? I am sure that this is very upsetting to you. It appears that your muscles have separated but this is an opinion based on very limited information. You may need a more complex operation called a separation of parts but It may be worth attemptinfg the muscle repair one more time.
