About

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.

Full 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.

9 participants in 2 patient groups

Laser Treatment Side

Experimental group

Description:

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.

Treatment:

Device: Laser treatment

Control side

No Intervention group

Description:

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.
