Study: Patients with at least one hypertrophic active scars or
cheloid, phototypes I to IV, were enrolled in this prospective study.
The scar was treated with a (Ekkylite, Ekkyo, Aix en Provence,
France) 810 nm diode laser system delivering a top hat spot of
20 mm 4 mm. Treatments were applied every 3 weeks. Clinical
evaluations, digital pictures, improvement of life quality, patient’s
satisfaction were performed at each visit, then at 90 and 180 days
after the last session.
Results: Fifteen patients, on decoletage, limbs, back, face,
phototypes I to IV were included. Diminution of itching and
redness, reduced height and thickness, and whitening were noted
mostly after three sessions on hypertrophic scars. Results were
less reproducible on cheloids.
Conclusion: This innovative 810 nm diode laser is a new device
already used in practice for aesthetic surgery, and it may be
utilized to improve hypertrophic scar and cheloid after surgery.

Background: Severe cutaneous scarring affects patients
following trauma, burns and surgical procedures. Treating a scar
is a dynamic process since the scar changes as therapy progresses.
A combination of vascular, pigment and resurfacing lasers may be
needed for maximal scar improvement. Fractional lasers create
zones of ablation at variable depths. These zones may be used
immediately post-operatively to deliver drugs and other
substances to synergistically create a therapeutic response. By
delivering topical or intralesional corticosteroids immediately
after fractional laser therapy the drug may take advantage of the
ablative fractional channels to penetrate deep into dermal scars
and decrease fibroblast proliferation. Cutaneous scars can be
complex and thus the approach to therapy may need to be
multimodal. A new combination therapy is suggested that
incorporates the use of one or more wavelengths of laser in the same
treatment session as topical or intralesional triamcinolone acetonide
to synergistically decrease hypertrophic and keloidal scars.
Study: Retrospective study with 15 subjects with hypertrophic or
keloidal scars from 3rd degree burn injury, surgical or traumatic
injuries. Subjects were treated with three to five treatment
sessions of at least one or more wavelengths of laser and same day
immediately post-operative topical or intralesional delivery of
triamcinolone acetonide injectable suspension into fractional
ablative tunnels. Three blinded investigators evaluated
photographs taken at baseline and 6 months after the final
therapy session. Scores were assigned using a quartile
improvement score to evaluate overall improvement, dyschromia,
degree of hypertrophy and texture.
Results: Combination same session laser therapy and postoperative
corticosteroid delivery resulted in average overall
improvement of 2.73/3.0. Dyschromia showed the least amount of
improvement with texture showing the most improvement.
Conclusion: Combination same session therapy with multiple
laser wavelengths and laser assisted delivery of topical or
intralesional triamcinolone acetonide may offer an efficient, safe
and effective treatment of challenging cutaneous scars.
FRACTIONAL ABLATIVE RADIOFREQUENCY
TREATMENT FOR SKIN TYPES V–VI: RISK-
BENEFIT ANALYSIS

Background: Laser resurfacing has remained the gold standard
for the treatment of rhytides, dyspigmentation and skin laxity for
many years. However, the potential risks of resurfacing such as
infection, prolonged erythema, pigmentary changes and scarring,
especially in darker skin types, have led to a search for safer and
more effective treatments. Radiofrequency (RF) technology
produces volumetric heating of the dermis to elicit collagen
shrinkage and skin tightening. Fractionated radiofrequency
devices create controlled radiofrequency thermal zones (RFTZ) at
regularly spaced intervals with intervening normal tissue. Unlike
ablative and nonablative laser modalities, which cause significant
epidermal damage, RF devices have minimal epidermal effect and
may be safer for darker skin types. To assess the safety and
efficacy of a new bipolar ablative radiofrequency device in
the treatment of rhytides and texture in patients with skin
types V–VI.
Study: Twenty-five male and female subjects 35–70 years of age
with Fitzpatrick skin types V–VI with mild to moderate
photoaging were evaluated. Subjects underwent three monthly
full-face treatments with the fractional ablative radiofrequency
device. Energy settings were increased incrementally at each
treatment session as tolerated. Follow-up evaluations were
performed at each treatment interval and at 6 months following
the final treatment. Two non-treating physicians evaluated each
subject for changes in rhytides and skin texture.
Results: All subjects showed improvement in either rhytides or
skin texture. Post-treatment erythema was seen in 10 subjects.
Post-treatment swelling was seen in only 1 subject after 1
treatment. No pigmentary changes or scars was noted.
Conclusion: Bipolar fractional ablative radiofrequency
treatments may be successfully used to treat photodamage in skin
types V–VI.

THE EFFECTS OF FRACTIONAL
RADIOFREQUENCY MICRONEEDLE ON
PERIORBITAL WRINKLE OF KOREAN PATIENTS

Medicine, Seoul, Korea
Background: Fractional radiofrequency microneedle (FRM), the
minimally invasive device using insertion microneedles of bipolar
and monopolar radiofrequency for deep dermal heating, has been
used for various cosmetic problems in Korea. Asian periorbital
skin is thicker than white people, so more powerful dermal
heating is necessary. We investigated the usefulness of FRM for
periorbital wrinkle reduction.
Study: Twenty healthy volunteers with periorbital wrinkle over
grade 2 participated in this study. Every patients had three
treatments with 1-month interval and checked clinical
photograph, adverse problems and questionnaire about subjective
satisfaction and discomforts during 6 months. Pre- and postclinical
photographs were used for assessing wrinkle severity. It
was assessed by three independent, blinded dermatologists.
