EvaluationofNon-Ablative Laser for Treatment of Direct Brow Lift Scars
PhillipTenzel, Ben Erickson,Wendy Lee, SaraWester. Ophthalmology, BascomPalmer Eye Institute,Miami, FL, UnitedStates
Introduction:
The purpose of this study is to determine the efficacy of a non-ablativemicrosecond 1064nmNd:YAG laser (Laser
Genesis, Cutera, Brisbane, CA) in the treatment of surgical scars after direct brow-lift.The presence of prominent, unsightly scars
currently limits the acceptance of this technique,which is otherwise ideal inmany patientswho are poor candidates for coronal,
pretricial or endoscopic brow procedures.
Methods:
After baseline characteristicswere documented, patientswho underwent direct brow liftswere randomized to unilateral
laser treatment at 2-4week intervals for a total of 6 treatments.The opposite scar was not treated andwas used as a control.
Standardized photographswere taken at each visit, en face and 45 degree view. Before each treatment and one- and three-months
following the final treatment, scarswere assessed for overall cosmesis by the subject using a 1-10 scale. Subjects also graded each
treatment with regard to discomfort, swelling, redness, hair loss, and any other symptoms tomonitor for side effects.
The initial parameterswere pulse duration of 300microseconds, energy density of 14J/cm
2
, a spot size of 5mm, pulse rate of
7-10Hz, and 500 pulses, taking breaks as needed for patient comfort. Sunscreenwith SPF 30 or higher was applied in office after
treatment, and subjectswere instructed to use sunscreenwith SPF of 30 or greater every day for the duration of the study.
Results:
Follow-up data is being collected and analyzed at the time of submission.
Data presented previously showed statistically significant improvement in the treated brow scar before the 6
th
treatment as compared
to the control scar (p<0.05) and to the treatment scar before the first treatment (p<0.10) by paired t-tests. Early data also showed
5 patients reporting improvement, 1 remaining the same, and 1worsening. Improvement did not appear to lessenwith increasing
time between surgery and treatment.
Conclusions:
To be presented.
