Split-face comparison study of cryogen spray cooling versus pneumatic skin flattening in skin tightening treatments using a long-pulsed Nd:YAG laser.

Background: Nd:YAG pulsed lasers are used for non-ablative skin tightening treatment. A common drawback of this procedure is pain, which is often intolerable. Pneumatic skin flattening (PSF) is a new technology which alleviates pain in laser treatments.

Treatment of mesh skin grafted scars using a plasma skin regeneration system.

Objectives. Several modalities have been advocated to treat traumatic scars, including surgical techniques and laser resurfacing. Recently, a plasma skin regeneration (PSR) system has been investigated.

Treatment of traumatic scars using plasma skin regeneration (PSR) system.

Objectives: Several modalities have been advocated to treat traumatic scars, including surgical techniques and laser resurfacing. Recently, a plasma skin regeneration (PSR) system has been investigated. There are no reports on plasma treatment of traumatic scars.

Long-pulsed neodymium:yttrium-aluminum-garnet laser treatment for hypertrophic port-wine stains on the lips.

Pulsed dye laser (PDL) treatment of hypertrophic port-wine stains (PWSs) on the lips has demonstrated poor efficacy and a potential risk of dyspigmentation. PDL-resistant hypertrophic PWS may require treatment with deeper penetrating lasers such as a 1064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. The objective of this clinical study was to evaluate the efficacy and safety of a Nd:YAG laser for the treatment of hypertrophic PWSs on the lips.

Randomized, evaluator-blind, split-face comparison study of single cross-linked versus double cross-linked hyaluronic acid in the treatment of glabellar lines.

BACKGROUND At present, various hyaluronic acids are being used to rejuvenate facial skin. There is no comparative study of single cross-linked hyaluronic acid (SCHA) versus double cross-linked hyaluronic acid (DCHA). The objective of our study is to compare the effectiveness and complications of SCHA versus DCHA in the treatment of glabellar lines.

Comparison study of a long-pulse pulsed dye laser and a long-pulse pulsed alexandrite laser in the treatment of port wine stains.

Background: Port wine stains (PWSs) are commonly treated by the pulsed dye laser. Recently, a long-pulse pulsed alexandrite laser was used to treat bulky vascular malformations.

Objective: In the present study, we compare the efficacy and complications of the long-pulse pulsed dye laser (LPPDL) and the long-pulse pulsed alexandrite laser (LPPAL) in the treatment of PWSs.

Comparison study of intense pulsed light versus a long-pulse pulsed dye laser in the treatment of facial skin rejuvenation.

Currently, various nonablative skin resurfacing techniques are being used to rejuvenate facial skin, including lasers and intense pulsed light (IPL). There are few direct comparison studies between IPLs and lasers. The objective of our study is to compare the effectiveness of intense pulsed light versus a long-pulse pulsed dye laser (LPDL) in the treatment of facial skin rejuvenation.

Treatment of resistant port-wine stains with a variable-pulse pulsed dye laser.

Background: The conventional pulsed dye laser (PDL), operating at a wavelength of 585 nm and a pulse duration of 0.45 ms, usually does not achieve complete clearance in the majority of port-wine stains (PWSs).

Objective: In this study, we demonstrate the efficacy of a variable-pulse pulsed dye laser (VPPDL) equipped with cryogen spray cooling (CSC) in the treatment of PWS that have become resistant to PDL treatment.

Long-pulse pulsed dye laser delivered with compression for treatment of facial lentigines.

Background And Objective: The 595-nm long-pulsed dye laser (LPDL) has been used for the treatment of vascular lesions, and although it is well absorbed by blood, it is also well absorbed by melanin. To utilize this device for the treatment of facial lentigines, we attached a glass window to the tip of the laser's handpiece, allowing compression of the skin during treatment. This prospective study aims to evaluate the efficacy and complications of using a LPDL delivered with compression for the treatment of facial lentigines in Asian persons.

Mongolian spots with involvement of mandibular area.

A 1-year-old boy had grayish pigmentation on the left side of his face over the area supplied by the mandibular branch of the trigeminal nerve. Upon further examination, the lesion was also found on the left side of the neck, shoulder, upper arm, right lower back and buttock. The pigmentation was uniform in intensity.

Prospective direct comparison study of fractional resurfacing using different fluences and densities for skin rejuvenation in Asians.

Background And Objective: Fractional resurfacing is a new concept of cutaneous remodeling whereby laser-induced zones of microthermal injury are surrounded by normal untreated tissue. The aim of this study is to compare the efficacy and complications of Fraxel laser treatment when using different fluences and density settings.

Study Design/materials And Methods: Thirty female Asian patients were enrolled in the study.

Evaluation of fluence and pulse-duration on purpuric threshold using an extended pulse pulsed-dye laser in the treatment of port wine stains.

Laser therapy of port-wine stains (PWS) using the extended pulse pulsed-dye laser (EPPDL) is accepted as the optimal approach because the thermal relaxation time for the vessels in PWS is actually 1-10 msec. The purpose of this study is to elucidate the purpuric threshold using the EPPDL for treatment of PWS. One hundred and seventy-seven Japanese patients with PWS were recruited for this study.

Treatment of port wine stains with the pulse dye laser.

The pulsed dye lasers (PDL) are the gold standard in the treatment of port wine stains (PWS). However, clearance rates vary widely, and many lesions are not completely cleared with laser treatment. This article reviews the use of different types of PDL for the treatment of PWS.

Comparison study of a traditional pulsed dye laser versus a long-pulsed dye laser in the treatment of early childhood hemangiomas.

Background And Objective: The role of pulsed dye laser (PDL) in the treatment of childhood hemangiomas is still controversial because of the inherent characteristics of hemangiomas as well as the side effects of the PDL. Recently, the long pulsed dye laser (LPDL) with cryogen spray cooling (CSC) has been found relatively more effective and safer than the PDL in the treatment of port-wine stains and telangiectasia. This study was designed to compare the efficacy and complication rate of PDL versus LPDL for treating childhood hemangiomas.
