What causes crooked tummy tuck incisions/scars?

Some irregularity of an abdominoplasty incision
is not infrequent and is based on healing and the anatomy that you present
with. Most surgeons suggest the markings be performed before surgery in a
standing position because this will allow the greatest chance of an even
contour and final scar. Sometimes adjustments have to be made in the operating
room for tissue irregularities and that can sometimes result in a scar that is
not perfectly even or symmetrical.

The location of the scar can be influenced by patient asymmetries (scoliosis) or prior surgery.  These should be pointed out prior to surgery. Occasionally, it is surgeon error, but these are usually minor inconsistencies. All tummy tuck patients have got to be comfortable with the presence of a scar because that is necessary for the operation. Make sure you look at the SHAPE after surgery and remember that the scar is concealed by clothing most of the time anyway. There are many scar therapies out there but even so, a small percentage may go on to scar revision. You need to understand these points before going forward with surgery. Good luck!
