Fractional CO2 laser for the treatment of caesarean section scar: a randomized split scar study.

K.E Karmischolt, E. Taudorf, P. Philipsen, M. Haedersdal

• 12 patients.
• Caesarean scar over 1 year.
• Randomized treatment half of the scar.
• CO2 AFL: high fluence, low density, 3 sessions with 1 month interval
• Follow up: 1, 3 and 6 months
• Very significant improvement in thickness, erythema, and aspect of the side treated scar
• CCI: Another confirmation of the interest of lasers in scar treatment. A lecture to be presented to our gynecologists colleagues

Synergic Use of PDL 595 nm and Fractional CO2 laser treatments for Keloids
Aldana G, Viera M.

• 100 patients with keloid scars.
• Treatment with 595 nm PDL and fractional C02 during the same session.
• 3 sessions, 45 days interval.
• Results evaluation according to Vancouver scale with photographic pictures
• Improvement in thickness, erythema, appearance and pliability, with no recurrence one year later
• CCI: interesting intellectual approach but only few details on settings used

A pilot study to treat mild to moderate laxity of lower face and neck with a bipolar fractionated microneedle RF device.
M. Clementoni, R. Panchaprateep, P. Kosari, G. Munavelli

• 30 patients (7 M, 23 W) with moderate laxity of the face and neck.
• Treatment with intraneedle RF Infini TM (3p / session);
• 3 sessions with 1 month interval.
• Photos evaluation.
• Significant improvement of the studied parameters.
• CCI: Effectiveness of the technique but the used parameters, including the minimum pulse duration, 2 times higher than then parameters recommended by the manufacturer. This leads to more post-operative side effects but not mentioned.

Complications associated with the use of fractional CO2 laser for the treatment of skin rejuvenation.
R. Chacur, N. Chacur et al

• Retrospective study of 991 patients.
• Treatment with ablative fractional CO2 laser
• Complications already described elsewhere: herpes, bacterial infection, PIH…
• New: muscle paralysis (spontaneously regressive) of some muscles of the face when botox injections are performed during the same session.
• CCI: Demonstration of the interaction between laser and botulinum toxin with the role of the laser induced oedema in postoperative care.

Low downtime ablative fractional resurfacing
J. Joo, M. McClaren, S. Kilmer

New protocol developed with conventional ablative resurfacing
laser to reduce time and risk of postoperative care.
30 patients; treatment of perioral area
Parameters: increasing the fluence, but drastic decrease in density (less than 10%).
Postoperative care limited to 2 days.
Much better results than non ablative fractional techniques.
CCI: Could be a “second life” for conventional C02 lasers for those who conserved them.

Evaluation of a compact Home Use 1440 nm non ablative fractional laser to treat periorbital wrinkles.
Z. Rahman, S. Dhawan, J. Starr, R. Ostrowski

• 45 patients with phototype I-VI.
• Treatment of periorbital area with compact non ablative fractional laser 1440 nm (Tria TM).
• Daily treatment for 8 weeks and follow up 12 weeks after the end of the treatment.
• Improvement of 1 point on scoring scale and evaluation on photographic pictures.
• No side effects except transient erythema and edema.
• VAS Pain: 1.8 on 10
• CCI: Efficacy and safety of this home device. Moderate results. Middle and long term results remain uncertain.
