The Treatment of Melasma with Fractional Photothermolysis: A Pilot Study

DERMATOLOGIC SURGERY, Issue 12 2005
Cameron K. Rokhsar MD
Background. Melasma is a common pigmentary disorder that remains resistant to available therapies. Facial resurfacing with the pulsed CO2 laser has been reported successful but requires significant downtime, and there is a risk of adverse sequelae. Objective. To determine if melasma will respond to a new treatment paradigm, fractional resurfacing. Methods. Ten female patients (Fitzpatrick skin types III,V) who were unresponsive to previous treatment were treated at 1- to 2-week intervals with the Fraxel laser (Reliant Technologies, Palo Alto, CA, USA). Wavelengths of 1,535 and 1,550 nm were both used, and 6 to 12 mJ per microthermal zone with 2,000 to 3,500 mtz/cm2 were the treatment parameters. Four to six treatment sessions were performed. Responses were evaluated according to the percentage of lightening of original pigmentation. Two physicians evaluated the photographs, and each patient evaluated her own response. Results. The physician evaluation was that 60% of patients achieved 75 to 100% clearing and 30% had less than 25% improvement. The patients' evaluations agreed, except for one patient, who graded herself as 50 to 75% improved as opposed to the physician grading of over 75%. There was one patient with postinflammatory hyperpigmentation and no patient with hypopigmentation. No downtime was necessary for wound healing. Conclusions. Fractional resurfacing affords a new treatment algorithm for the treatment of melasma that combines decreased risk and downtime with significant efficacy. This treatment modality deserves further exploration to maximize benefits. RELIANT technologies LOANED THE FRAXEL LASER FOR THE STUDY. RICHARD E.

Abstract Background and Objectives Though post-inflammatory hyperpigmentation (PIH) is probably the most common complication of laser resurfacing and appears to correlate directly with the intensity of the patient's natural pigmentation, there is very little data that specifically addresses the risks of dyspigmentation in more darkly pigmented patients (Fitzpatrick skin types IV and above). The objective of this study was to evaluate the long-term dyspigmentation of patients with skin type IV having radial laser resurfacing. Study Design/Materials and Methods A retrospective review of the clinical efficacy, incidence of dyspigmentation and other adverse effects, as well as the pre/post-operative protocol of 22 patients with Fitzpatrick skin type IV who were a minimum of 1 year post-operative following facial laser resurfacing. Results The average patient achieved greater than 50% improvement, indicating adequate treatment being delivered. PIH occurred in 68% of patients, starting 1 month post-operative and lasting 3.8 months. There was no correlation to pre-treatment or type of laser used as far as incidence of PIH. True hypopigmentation was not seen in this group of 22 patients. Conclusions PIH is the most common complication of facial resurfacing in patients with skin type IV. It is not preventable by choice of laser or skin care regimen pre-operative, but appears to respond to appropriate treatment once it has developed. Lasers Surg.

Minimally Ablative Erbium:YAG Laser Resurfacing of Facial Atrophic Acne Scars in Asian Skin: A Pilot Study

DERMATOLOGIC SURGERY, Issue 5 2008
YONG-KWANG TAY MD
BACKGROUND Atrophic scars are dermal depressions caused by collagen damage most commonly occurring after inflammatory acne vulgaris. There are little published data regarding the effectiveness and safety of minimally invasive lasers in the treatment of atrophic acne scars in darker skin types. OBJECTIVE The purpose was to evaluate the efficacy and safety of a low-fluence 2,940-nm erbium:YAG laser in the treatment of atrophic acne scars in Asian patients. MATERIALS AND METHODS Nine patients aged 19 to 45 years with mild to moderate atrophic facial scars and Skin Types IV and V were treated with topical anesthesia and one to two passes with an erbium:YAG laser two times at 1-month intervals. Treatment parameters were 6-mm spot size, fluence of 400 mJ, pulse duration of 300 ,s, and repetition rate of 2 Hz. RESULTS At 2 months after the last treatment, mild to moderate clinical improvement was noted in all patients compared to baseline. Treatment was well tolerated. Side effects consisted of posttreatment erythema, peeling, and crusting, which resolved within 1 to 2 weeks. There was no postinflammatory hyper- or hypopigmentation, blistering, or hypertrophic scarring. CONCLUSION Low-fluence erbium:YAG facial resurfacing was effective and safe in patients with mild to moderately severe atrophic acne scarring. [source]

Retinoids and Wound Healing

DERMATOLOGIC SURGERY, Issue 10 2006
MARK ABDELMALEK MD
BACKGROUND Retinoids are widely used in dermatology and may play a role in wound healing. The exact role of retinoids in wounds is confusing and controversial, however. Systemic retinoids are presumed to be detrimental to wound healing; however, this standard is based on isolated reports. OBJECTIVE The objective was to provide a critical review of the available literature regarding the role of both topical and systemic retinoids in various aspects of wound healing. CONCLUSIONS Pretreatment with retinoids likely promotes wound healing after facial resurfacing procedures and full- or partial-thickness wounds. While the evidence is mixed regarding the effects of retinoids applied to fresh and healing wounds, the majority of the evidence available shows favorable wound-healing properties in this setting. The medical,legal standard regarding the avoidance of facial resurfacing and surgical procedures in patients on or recently completing a course of systemic retinoids was likely prematurely established.

Face resurfacing using a cervicothoracic skin flap prefabricated by lateral thigh fascial flap and tissue expander

MICROSURGERY, Issue 7 2009
Ph.D., Qingfeng Li M.D.
Background: Resurfacing of facial massive soft tissue defect is a formidable challenge because of the unique character of the region and the limitation of well-matched donor site. In this report, we introduce a technique for using the prefabricated cervicothoracic skin flap for facial resurfacing, in an attempt to meet the principle of flap selection in face reconstructive surgery for matching the color and texture, large dimension, and thinner thickness (MLT) of the recipient. Materials: Eleven patients with massive facial scars underwent resurfacing procedures with prefabricated cervicothoracic flaps. The vasculature of the lateral thigh fascial flap, including the descending branch of the lateral femoral circumflex vessels and the surrounding muscle fascia, was used as the vascular carrier, and the pedicles of the fascial flap were anastomosed to either the superior thyroid or facial vessels in flap prefabrication. A tissue expander was placed beneath the fascial flap to enlarge the size and reduce the thickness of the flap. Results: The average size of the harvested fascia flap was 6.5 × 11.7 cm. After a mean interval of 21.5 weeks, the expanders were filled to a mean volume of 1,685 ml. The sizes of the prefabricated skin flaps ranged from 12 × 15 cm to 15 × 32 cm. The prefabricated skin flaps were then transferred to the recipient site as pedicled flaps for facial resurfacing. All facial soft tissue defects were successfully covered by the flaps. The donor sites were primarily closed and healed without complications. Although varied degrees of venous congestion were developed after flap transfers, the marginal necrosis only occurred in two cases. The results in follow-up showed most resurfaced faces restored natural contour and regained emotional expression. Conclusion: MLT is the principle for flap selection in resurfacing of the massive facial soft tissue defect. Our experience in this series of patients demonstrated that the prefabricated cervicothoracic skin flap could be a reliable alternative tool for resurfacing of massive facial soft tissue defects. © 2009 Wiley-Liss, Inc.
