Brief Summary:
The purpose of this study is to determine the efficacy of the 1064nm Neodymium yttrium aluminum garnet (Nd:YAG) laser (Laser Genesis, Cutera TM) in the treatment of surgical scar after direct brow lift.

Condition or disease Intervention/treatment Phase
Scar Device: Laser treatment Not Applicable

Detailed Description:
Patients who undergo a direct brow lift may participate in this study. Participants will receive laser treatment on one of the two surgical wounds (side of treatment will be chosen randomly by an independent source). Treatment parameters will be 500 spots and 10-14 megajoules (mJ) depending on skin type. The opposite side brow scar will not be treated until 1 month after the study is completed (if the patient elects to treat the contralateral brow after study completion this will be done at no charge to the patient). This treatment will be given at 2-4 week intervals for 6 treatments. Photographs will be taken at each visit, and they will be assessed based on different parameters by an examiner, as well as judged by the patient based on overall appearance.

Arm Intervention/treatment
Experimental: Laser Treatment Side
Each patient was randomized to have one of two scars treated with Laser Genesis. The treatment was administered by manually scanning the rapidly pulsed laser in an even, painting motion throughout the entire treatment zone. The eyebrow hairs were covered with white tape to prevent inadvertent alopecia. The laser handpiece was oriented perpendicular to the skin at all times, at a distance of 1-2 cm. Patients were instructed throughout to give verbal feedback regarding if the area was "too hot" as an additional safeguard against epidermal damage.
Device: Laser treatment
Non-ablative, non-fractional, microsecond-pulsed Nd:YAG laser 500-1000 pulses, 0.3 msec pulse duration, 10-14 J/cm2, 5 mm spot size
Other Names:
  • Laser Genesis, Cutera
  • 1064 microsecond-pulsed Nd:YAG laser

No Intervention: Control side
Each patient had a scar which was randomized to not undergo treatments with Laser Genesis, and was used as a control. Patients were not allowed to undergo laser or any other scar treatments with the exception of sun protection for the control scar for the duration of the study.

Primary Outcome Measures :
  1. Relative Improvement [ Time Frame: 1 month after final treatment ]
    Which scar, overall, appears to have improved more from initial to final visit, as rated by blinded examiner of photographs

Secondary Outcome Measures :
  1. Overall Appearance [ Time Frame: 10 minutes before first treatment and at the final visit ]
    Subjects were asked to rate overall cosmesis of both the treated and control scars on a 1-10 scale, with 1 being extremely poor and 10 being extremely excellent, as rated by participant

  2. Hair Loss [ Time Frame: within 1 hour after final treatment ]
    After each laser session, subjects were asked to rate perceived amount of hair loss from both the treated and control scars on a 1-10 scale, with 1 being none at all and 10 being extremely significant
