title: Radiosurgery versus carbon dioxide laser for dermatochalasis correction in Asians.
abstract: OBJECTIVE
  Carbon dioxide (CO(2)) laser and radiosurgery are techniques commonly employed in oculoplastic surgery. However, there is no literature comparing their results in blepharoplasty.
  
  
  METHODS
  Twenty Chinese patients with dermatochalasis underwent radiosurgery in one upper eyelid and CO(2) laser in the contralateral eyelid. Intraoperative time, hemorrhage, and pain control were assessed. Subjects were evaluated at postoperative 1 hour, 1 week, 1 month, and 3 months for hemorrhage and wound healing by a masked assessor.
  
  
  RESULTS
  All patients reported minimal pain with either technique. A significantly shorter operative time was achieved with CO(2) laser, with better intraoperative hemostasis. There was no significant difference in postoperative hemorrhage and wound swelling between radiosurgery and CO(2) laser. No significant intraoperative complications were noted.
  
  
  CONCLUSIONS
  Both radiosurgery and CO(2) laser are equally safe and effective for upper lid blepharoplasty. CO(2) laser achieves shorter operative time with superior intraoperative hemostasis.
