Every plastic surgeon will have a different skill set, but umbilicoplasty is fairly straightforward. Some products of healing are not predictable and not a reflection of poor surgical technique. In your case, I am not sure what exactly happened, and I would need more information or an exam to make a determination about what needs to be done.If the belly button has been revised once and is still not satisfactory at one year following the revision, there may not be a great deal anyone can do. There are a variety of therapeutic modalities that can be utilized, but none are entirely effective for hypertrophic scars. The nature of the contour of the tummy tuck scar can almost always be made better, but healing is not 100% predictable. Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA
