title: Long-term effects of one general pass laser resurfacing. A look at dermal tightening and skin quality.
abstract: BACKGROUND
  Laser resurfacing with high-energy, short-pulsed lasers is generally a safe and cosmetically rewarding procedure. Nevertheless, the aggressive use of these instruments has the potential for unpredictable, undesirable complications. It has long been held that multiple passes are needed to achieve dermal tightening (collagen shrinkage), which will result in a cosmetically desirable appearance. The observation of skin tightening after one general pass has not been previously reported.
  
  
  OBJECTIVE
  To look at the long-term results after only one general pass and of focal multiple passes over lines, with particular attention to the degree of tightening and quality of the skin.
  
  
  METHODS
  Fifteen patients with varying degrees of photodamage and resulting skin laxity, and with at least eighteen months follow-up, were evaluated. High quality photographic records were compared between pre- and postoperative pictures at three different angles on each.
  
  
  RESULTS
  Cosmetically significant dermal tightening was observed in all of these patients. This was noted in some patients after six months and continued for several months after. All patients were pleased with the cosmetic improvement obtained. Of note were fast healing and the absence of significant complications in these patients.
  
  
  CONCLUSIONS
  The appearance of dermal tightening as a late occurrence in the postoperative course after one single general pass has not been previously reported. When numerous general passes are done, dermal tightening is quite impressive and appears much sooner; however, much of this result is due to edema and the resulting skin quality in these patients is different. A more natural look is achieved if only one pass is done. The procedure is safer and has a faster recovery period.
