BACKGROUND AND OBJECTIVES: A 28-year-old female presented with extensive scarring after a traumatic injury to her right lower extremity. She had been hit by a vehicle one year prior to presentation and had several open fractures with extensive overlying cutaneous damage, which required multiple surgeries and skin grafts. She had limited range of motion of the affected limb secondary to scar contracture. STUDY DESIGN/MATERIALS AND METHODS: The patient received 6 treatments with a non-ablative fractional resurfacing (NAFR) device with two wavelengths (Fraxel DUAL, Solta Medical, Hayward, CA) spaced 4-8 weeks apart...

BACKGROUND: The combination of simultaneous surgical rhytidectomy with ablative resurfacing has been a controversial procedure due to the concern of postoperative wound healing. Traditional ablative resurfacing lasers are believed to have higher rates of complications, leading to delayed healing and skin flap loss when combined with face rhytidectomy surgeries. With the development of fractionated ablative laser therapy, there has been increased interest in combining these two procedures...

PURPOSE: To employ a multi-3D camera system for patient and treatment equipment tracking using the Kinect v2 camera system. METHODS: The system has two cameras, a color camera (RGB) and a time-of-flight infrared camera (IR). The IR is used to measure the distances between the camera and the subject for each IR pixel producing a point cloud of fraxels (fragment pixel, our terminology for a measured location + color generated by a 3D camera). We intend to use multiple Kinect cameras to generate a real-time digital model of the treatment room...

BACKGROUND AND OBJECTIVE: Identification of methods to enhance anagen entry can be helpful for alopecia. Recently, nonablative laser has been proposed as a potential treatment for alopecia. However, how the laser parameters affect stem cell activity, hair cycles and the associated side effects have not been well characterized. Here we examine the effects of irradiation parameters of 1,550-nm fractional laser on hair cycles. STUDY DESIGN/MATERIALS AND METHODS: The dorsal skin of eight-week-old female C57BL/6 mice with hair follicles in synchronized telogen was shaved and irradiated with a 1,550-nm fractional erbium-glass laser (Fraxel RE:STORE (SR1500) Laser System, Solta Medical, U...

In this case study, we present a safe and novel treatment for a patient with soft tissue hand disability caused by severe and chronic lupus and cutis laxa (CL). This patient was a woman in her 50s with a 20-year history of systemic lupus erythematous (SLE) and multiple sclerosis who developed hand disability because of the drastic loss of firmness in her soft tissue, extending from the dermis down to the ligaments. The likely cause was CL with SLE synovitis, exacerbated by corticosteroid tapering. Fractional photothermolysis (FP) LASER (Fraxel DUAL 1550/1927; Solta Medical) therapy profoundly alleviated her joint locking in addition to improving the firmness of the overlying skin to reverse her hand disability...

BACKGROUND: Rhinophyma is a progressive and disfiguring proliferative disorder of the nose, which is related to chronic rosacea. Many different treatment modalities have been utilized both alone and in combination including: loop cautery, CO2 laser, argon laser, dermabrasion, cryotherapy, radiotherapy, full-thickness excision, skin graft, flap reconstruction, and cold scalpel. CO2 resurfacing has been considered first line therapy but is often associated with a shiny, scarred appearance, with patulous pores, and with loss of pigmentation...

UNLABELLED: The Fraxel laser has been a useful method for skin resurfacing. According to recent reports, vitamin C has beneficial effects for the skin. However, there is a paucity of data about the effect of vitamin C associated with the Fraxel laser. This study aimed to assess the effect of topical vitamin C as a post-Fraxel regimen. The study involved 44 Koreans, who wished to improve their facial skin aesthetics. All the patients were treated by Fraxel laser twice, with a 4-week interval between treatments...

BACKGROUND AND OBJECTIVE: The paramedian forehead flap is an excellent choice when repairing a large nasal defect. However, even when carefully thinned, the flap may develop a bulky appearance, an ill-fitting contour, or trap door deformity. When on the face, these suboptimal results can be quite distressing. Surgical and non-surgical options for improvement exist. Surgical options include additional debulking and reorientation of the flap. Non-surgical options include intralesional corticosteroids or 5-flourouracil, dermabrasion, and ablative and non-ablative laser resurfacing...

BACKGROUND AND OBJECTIVES: Non-ablative fractional resurfacing (NA FR) has been shown to be effective for photorejuvenation and acne scarring. Previous studies indicated that density, more than pulse energy, was associated with post-inflammatory hyperpigmentation (PIH) in Asians. The objective of this retrospective study was to assess the efficacy and complications of eight passes of NA FR ('full-NA FR') with the 1,550 nm erbium-doped fibre fractional laser (Fraxel SR laser system, Solta Medical, Hayward, CA) versus four passes ('mini-NA FR') with comparable pulse energy and treatment level as 'full-NA FR', but double the number of treatment sessions in Asian acne scar patients...
