background: primary axillary hyperhidrosis (pah) is a common condition with a great impact on the patient’s quality of life (qol). it is associated with serious social, emotional, and occupational distress. the aim of this study was to investigate the qol in patients with pah before and after treatment with fractionated microneedle radiofrequency (fmr). materials and methods: we evaluated 25 pa...

BACKGROUND Fractionated microneedle radiofrequency (RF) devices have been reported to be effective in treatment of various dermatologic disorders. OBJECTIVES To analyze histometric changes in skin-RF interactions using a fractionated microneedle delivery system. MATERIALS AND METHODS RF energies were delivered using a fractionated microneedle device to an in vivo minipig model with penetrat...

BACKGROUND Nonablative radiofrequency (RF) devices have been shown to be clinically effective for the treatment of moderate to severe acne lesions. OBJECTIVE To evaluate the efficacy and safety of a fractionated microneedle RF device in the treatment of inflammatory acne vulgaris. METHODS Eighteen patients (15 male, 3 female; mean age 27, range: 19-33; Fitzpatrick skin type IV) with moderat...

INTRODUCTION Microneedle radiofrequency is a novel method that allows non-thermal penetration of the epidermis followed by RF coagulation in selected depth of the dermis surrounded by zone of non-coagulative volumetric heating. The first generation of Microneedle RF applicators used insulated needles. These treatments were limited by a few factors, including low volume of dermal heating, lack o...

Sixteen patients with type I atrial flutter underwent an attempt at radiofrequency catheter ablation (8 women, 8 men, mean age 53 +/- 11 years). The primary criterion used to identify sites for radiofrequency energy delivery was the identification of a fractionated electrogram. Radiofrequency energy was delivered for 20 to 30 seconds. Radiofrequency catheter ablation was acutely successful in 1...

BACKGROUND Fractional technology overcomes the problems of ablative lasers, such as inaccurate depth control and damage to the epidermis. Minimally invasive fractional radiofrequency microneedle devices allow for more-selective heating of the dermis. OBJECTIVE To evaluate the clinical efficacy of fractional radiofrequency microneedle (ERM) treatment in acne scars and large facial pores. MAT...

BACKGROUND AND OBJECTIVES For skin rejuvenation, microneedle fractional radiofrequency (RF) is a recently developed minimally invasive method for delivering RF energy directly into the skin using microneedle. Additionally, the use of growth factors in skin rejuvenation is emerging as a novel anti-aging treatment. We evaluated efficacy and safety of microneedle fractional RF for skin rejuvenatio...
