The Role of Er-yag Glass Laser in Skin Resurfacing.

Facial Plast Surg 2022 Apr 7;38(2):163-165. Epub 2022 Jan 7.

Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, Verona, Italy.

Following our survey, we can appreciate that a variety of laser platforms exist to rejuvenate the skin by resurfacing the outer layer of the skin as well as heating the lower layers of the dermis. Based on reliable clinical effectiveness and a limited side effect profile, we can confirm that nonablative fractionated technologies greatly improve the appearance of lentigines, rhytids; eliminate sun damage, attenuate scarring due to acne and other causes; and treat hyperpigmentation. The Fraxel (Solta Medical) laser system delivers pulses across a wide range of density and energy levels. Read More

Characteristics of Non-Ablative Resurfacing of Soft Tissues by Repetitive Er:YAG Laser Pulse Irradiation.

Lasers Surg Med 2021 11 1;53(9):1266-1278. Epub 2021 Apr 1.

Faculty of Mechanical Engineering, University of Ljubljana, Askerceva 6 SI-1000, Ljubljana, Slovenia.

Background And Objectives: Recently, several minimally invasive gynecological, ENT and esthetic procedures have been introduced that are based on delivering "smooth" sequences of Er:YAG laser pulses to cutaneous or mucosal tissue at moderate cumulative fluences that are not only below the ablation threshold but typically also do not require local anesthesia.  To explain the observed clinical results using "smooth-resurfacing," it has been suggested that in addition to the direct heat injury to deeper-lying connective tissues, there is an additional mechanism based on indirect triggering of tissue regeneration through short-exposure, intense heat shocking of epithelia. The goal of this study is to improve understanding of the complex dynamics of the exposure of tissues to a series of short Er:YAG laser pulses, during which the thermal exposure times transition from extremely short to long durations.

Absorbable Suspension Sutures: Recommendations for Use in a Multimodal Nonsurgical Approach to Facial Rejuvenation.

J Drugs Dermatol 2021 01;20(1):23-29

Background: Absorbable suspension sutures are an effective nonsurgical modality for correction of ptosis and tissue repositioning in the face and neck. The PLLA/PLGA suture is entirely absorbable and has a dual effect in that it both lifts tissues and induces collagenesis, thereby restoring contour. In clinical practice, nonsurgical modalities are rarely used in isolation, and combination treatments with fillers, neuromodulators, lipolysis, and energy-based devices are common. Read More

Paradigms in Complex Facial Scar Management.

Semin Plast Surg 2020 Nov 24;34(4):305-313. Epub 2020 Dec 24.

Otolaryngology and Facial Plastic Surgery Associates, Fort Worth, Texas.

The process of scar formation is a sequela of the healing following soft tissue injury extending to, or through, the reticular dermis. Scars, within the head and neck in particular, may be physically disfiguring with resultant psychosocial implications. Mitigation of excessive scar formation during the healing process following surgery, or in the setting of trauma, begins with meticulous soft tissue handling and reconstructive technique. Read More

Wound Healing Treatments After Ablative Laser Skin Resurfacing: A Review.

J Drugs Dermatol 2020 Nov;19(11):1050-1055

Laser resurfacing has progressed since the 1980s to treat a variety of medical and aesthetic indications with ever-evolving safety parameters. While laser technology has evolved to provide a more favorable safety profile and decrease wound healing time, advances in post-procedure healing agents have also helped to mitigate adverse effects, such as persistent erythema, dyspigmentation, acneiform eruptions, dermatitis, infections, and scarring. We reviewed the evidence of growth factors, stem cells, silicone and silicone polymers, botanical based treatments, fatty acids, probiotics, and closed dressings on post-ablative laser skin resurfacing.

Outcomes and adverse effects of ablative vs nonablative lasers for skin resurfacing: A systematic review of 1093 patients.

Dermatol Ther 2021 01 2;34(1):e14432. Epub 2020 Nov 2.

Skin & Laser Surgery Center of New England, Nashua, New Hampshire, USA.

It is generally believed that ablative laser therapies result in prolonged healing and greater adverse events when compared with nonablative lasers for skin resurfacing. To evaluate the efficacy of ablative laser use for skin resurfacing and adverse events as a consequence of treatment in comparison to other modalities, a PRISMA-compliant systematic review (Systematic Review Registration Number: 204016) of twelve electronic databases was conducted for the terms "ablative laser" and "skin resurfacing" from March 2002 until July 2020. Studies included meta-analyses, randomized control trials, cohort studies, and case reports to facilitate evaluation of the data. Read More
