بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته
هدف: این مطالعه به منظور بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته انجام شده است. روش مطالعه: 116 فرد مبتلا به ضایعات پیگمانته از نوع فرکل و خال وارد مطالعه شدند که 58 مورد با استفاده از q-switched nd yag laser و 58 مورد با لیزر erbium درمان شدند و در نهایت میزان اثربخشی (از بین رفتن کامل ضایعات) در دو گروه تعیین و مقایسه گردید. یافته ها: در این مطالعه...
15 صفحه اولEvaluation of the efficacy of the Q switched ruby laser in the treatment of benign pigmented skin lesions
Background and aim: It is possible to use light sources suxh as lasers to destruct melanosomes and treat pigmented skin lesions. One of the most commonly used laser systems is Q switched ruby laser with a wave-length of 694 nm. This study was performed to evaluate the efficacy of the Q switched ruby laser in the treatment of pigmented skin lesions including lentigines (simplex or solar) and caf...
متن کاملQ - switched Cryogenically Cooled Yb : YAG Laser
This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.
متن کاملCryotherapy is more effective and faster than Q-switched Nd-YAG laser fordepigmentation in universal vitiligo patients
Background: Although cryotherapy has been reported as atechnique for depigmenting residual pigmented patches inpatients with universal vitiligo, Q-switched Nd-YAG lasershave not yet been used for this purpose. The aim of this studywas to compare the efficacy of cryotherapy with that of 532nmQ-switched Nd-YAG laser therapy for depigmentation in patientswith universal vitiligo.Method: Six adult p...
متن کاملCombined therapy using Q-switched ruby laser and bleaching treatment with tretinoin and hydroquinone for acquired dermal melanocytosis.
BACKGROUND AND OBJECTIVE Acquired dermal melanocytosis (ADM; acquired bilateral nevus of Ota-like macules) is known for its recalcitrance compared with Nevus of Ota, and we assume that one of the reasons is a higher rate and degree of postinflammatory hyperpigmentation (PIH) seen after laser treatments. METHODS Topical bleaching treatment with 0.1% tretinoin aqueous gel and 5% hydroquinone oi...
