title: Facial augmentation with core fat graft: a preliminary report.
abstract: BACKGROUND
  Facial rejuvenation with autologous fat has the advantage of replacing or augmenting tissue with like tissue. The results of injected fat are unpredictable because of cellular trauma and other factors. Excised whole or en bloc fat grafting has been shown experimentally to have a greater percentage of adipocyte survival when compared with blunt cannula delivery techniques. En bloc grafting, however, requires an incision for the harvesting and placement of the fat graft with visible scars. A novel, less traumatic cylinder core fat harvest and delivery technique for facial augmentation with minimal incisional access is reported here.
  
  
  METHODS
  Twenty-six facial augmentation procedures were performed involving the malar area, buccal area, lips, nasolabial folds, and mental region. Fat transfer volume ranged between 1 and 4 cc per site. In this report, 16 patients' results were documented 6 to 16 months postoperatively (mean follow-up time, 9.5 months) with a postoperative questionnaire and photographs.
  
  
  RESULTS
  Social recovery for patients was short, with a recovery time of 2 to 20 days (mean, 10.91 days). There were no procedure-related complications at the fat harvest or recipient graft sites. The need for overcorrection was minimal. Graft maintenance during the average follow-up at 9.5 months appeared excellent and without appreciable volume loss. The mean patient satisfaction score was 7.64 +/- 2.97 on a scale of 0 to 10.
  
  
  CONCLUSIONS
  The authors' preliminary results have demonstrated that this technique is effective and highly predictable. The surgical time was short, and patient recovery time has been significantly reduced compared with recovery time after other fat injection techniques.
