At four months post surgery, I usually expect to see virtually the final result of liposuction. I do not , however, use external ultrasound or Smartlipo, but traditonal and power assisted liposuction. I advise patients now to rely on circumference measurements, but to judge the results based on appearance of the the treated area along with a comparison with their pre-operative condition.
If there has been no documented difference between pre and post-op photos, then additional liposuction can be done. I advise patients to wait at least nine to twelve months or more after the date of their original surgery, before proceeding with any repeat surgery. If revision surgery is performed too soon, the scarring from the original surgery will likely limit the ability to retrieve more fat and there will likely be excessive bleeding, also limited the results of the revision.
