<p>BACKGROUND: Fractional ablative lasers have been shown to be safe and effective for improving wrinkles, scars, skin texture, and dyspigmentation. However, the exact effects of this technology in vivo on epidermal and dermal skin constituents have not been delineated. This study evaluated the in vivo histological effects over time of treatment with a fractional ablative CO2 system, using different treatment parameters. MATERIALS AND METHODS: Healthy adult volunteers were enrolled in this multicenter clinical study...

REVIEW
R Thiesmann
Blepharoplasty is one of the most frequently performed plastic cosmetic interventions. For this purpose the CO2 laser is an instrument that can be used as a laser scalpel to cut as well as in its ablative function to remove skin irregularities, such as scars and tumors and also to treat changes of the skin due to aging. Fractionated laser irradiation reduces the duration of skin redness and the postoperative rehabilitation time after a resurfacing. The advantages of the CO2 laser are a gentle intraoperative preparation and less postoperative swelling due to an additional cauterization of blood vessels...

Despite the growth of technically more sophisticated skin resurfacing modalities, such as those based on light, radiofrequency, and ultrasound, chemical peel procedures have risen 5 to 25 percent over the past year alone. Chemexfoliation carries historical significance and has markedly evolved since its inception in ancient times. As a result of plastic surgery and dermatologic advancements, modern-day chemexfoliation offers plastic surgeons additional safe and effective options for patients with rhytides, dyschromias, and other signs of light- and environment-induced skin damage...

Kasandra R Dassoulas, Traci L Hedrick, Chris A Campbell
Low-lying rectal cancers are being treated more frequently with robotic-assisted abdominoperineal resection, obviating the need for laparotomy and the ability to raise vertical rectus abdominis musculocutaneous flaps. For female patients, posterior vaginectomy often accompanies the resection. Combined pudendal thigh flaps as an extension of bilateral gluteus advancement flaps allow for posterior vaginal resurfacing with thin pliable fasciocutaneous flaps, which rest on the gluteal flap soft-tissue bulk that obliterates the pelvic dead space...

REVIEW
Shivani B Kaushik, Andrew F Alexis
Background: Nonablative laser resurfacing represents one of the major advances in procedural dermatology over the past decade. However, its use in darker skin types is limited by safety concerns and a relative lack of available data. Aim: To provide evidence-based recommendations for the use of fractional lasers in darker skin types. Evidence review: A broad literature search of PubMed/Medline database was conducted in April 2016 using the term fractional lasers. A free text search of keywords including fractional resurfacing, nonablative lasers, skin type, skin of color, ethnic skin, Fitzpatrick skin type, Asian skin, African Americans, Afro-Caribbean, and Hispanics was also executed...

Kian Karimi, Alexandra Reivitis
Traditional rejuvenation techniques include chemical peels, rhytidectomy of the skin, laser resurfacing, injection of dermal fillers and neurotoxins, and invasive surgical procedures. Patients with brow ptosis, jowl formation, and deepening nasolabial folds currently seek antiaging procedures with no incisions and minimal downtime such as thread-lifting with barbed sutures. The present report describes a case in which polydioxanone threads were used to lift the lower third of a patient's face. Fillers were used to supplement the results achieved by the thread lift because often, when tissue has been lifted, volume deficits are revealed, which can be corrected with dermal fillers...

Fractional CO2 laser is one of the most effective treatment options used to resurface scars; However, most previous studies have been performed on mature scars at least 2 months after surgery. Recent studies have emphasized the importance of early treatment to reduce scar formation. In the present study, we described our experience with fractional CO2 laser intervention before skin suture during scar revision surgery in Asians, and found the treatment was safe and effective.

The development and use of light and lasers for medical and cosmetic procedures has increased exponentially over the past decade. This review article focuses on the incidence of reported cases of skin cancer post laser or IPL treatment. The existing evidence base of over 25 years of laser and IPL use to date has not raised any concerns regarding its long-term safety with only a few anecdotal cases of melanoma post treatment over two decades of use; therefore, there is no evidence to suggest that there is a credible cancer risk...

Soo Hyun Woo, Tae Hui Bae, Woo Seob Kim, Han Koo Kim
Reconstruction of pharyngocutaneous fistula (PCF) or orocutaneous fistula is always a challenging task. It has many causes and is especially related to radiation therapy after resection of head and neck cancers. There are many reports of surgical procedures for fistula repair. For example, 2-stage methods, methods of combining multiple flaps, and methods of using chimeric flaps have been reported. However, there is no established simple method as a treatment of choice. The authors describe 5 patients of head and neck fistulas and recommend a useful 1-stage reconstruction method using a double skin paddle free flap...
