facial radiofrequency

BACKGROUND: The application of radiofrequency (RF) and HIFES on the body provides improvement in skeletal muscle tissue, reduction in fatty tissue, reorganization of connective tissue, and skin texture improvement. However, overall facial appearance relies on both skin and underlying structures, specifically muscles and connective tissue which have to be treated as one unit to achieve proper care while preserving fatty layers that define youth facial appearance. AIMS: The aim of this study is to find whether the effect of novel RF + HIFES is safe and can induce the lifting of soft tissue and overall improvement in facial appearance...

BACKGROUND: Acne vulgaris (AV) is a prevalent skin condition known for its potential to cause scarring and psychological distress, often leading to diminished self-esteem. While topical and oral treatments are commonly prescribed, some patients experience treatment failure, adverse effects, or contraindications to conventional therapies. In response to these challenges, laser and energy-based device therapies have emerged as promising alternatives for individuals who fall into these categories, showing considerable potential in the treatment of AV...

MRI is a noninvasive, ionizing radiation-free imaging modality that has become an indispensable medical diagnostic method. The literature suggests MRI as a potential diagnostic modality in dentomaxillofacial radiology. However, current MRI equipment is designed for medical imaging (eg, brain and body imaging), with general-purpose use in radiology. Hence, it appears expensive for dentists to purchase and maintain, besides being complex to operate. In recent years, MRI has entered some areas of dentistry and has reached a point in which it can be provided following a tailored approach...

BACKGROUND: Skin boosters denote injectables that promote global improvement of the skin which includes skin texture, elasticity, hydration, and overall appearance. Polynucleotide (PN) products have become popular, but there is surprisingly little guidance on their use. We aimed to maximize the safety and efficacy of injectable PN by providing information on their pattern of practice among board-certified dermatologists. METHODS: A total of 235 Korean board-certified dermatologists familiar with skin boosters participated in a survey which questioned the participant's years of practice, selection of skin boosters in one's clinic, and range of lasers and light sources as well as skin care devices that are available...

BACKGROUND: Persistent primitive trigeminal artery variant (PPTAv) is a rare remnant of the primitive intracranial embryonic anastomotic arteries, and its persistence has an unknown etiology. Trigeminal neuralgia attributed to a PPTAv passing through Meckel's cavity is extremely uncommon. CASE PRESENTATION: A 73-year-old woman presented with right-sided facial pain for 10 years that had failed to respond to medication. Magnetic resonance angiography suggested the presence of a PPTAv compressing the trigeminal nerve, as the abnormal artery originated from the right internal carotid artery...

BACKGROUND: Microneedle fractional radiofrequency (MFR) is commonly used for skin laxity treatment, and poly-L-lactic acid (PLLA) can stimulate collagen synthesis in the body. However, the synergy of their combination for skin rejuvenation has not been proven. We aimed to evaluate the combined efficacy of PLLA and MRF and the potential mechanism underlying skin laxity. METHODS: This prospective, randomized study included C57BL/6 mice treated with MFR, MFR+PLLA, and CO2 laser+PLLA and 32 patients who underwent split-face treatments with MFR or MFR+PLLA twice every 2 months...

BACKGROUND: During facelift surgery, anterior platysmaplasty (AP) has been used for decades, but it limits lateral advancement and can induce contour irregularities. Radiofrequency (RF)-assisted-liposuction in the anterior neck can avoid these disadvantages by tightening skin without open surgery. PURPOSE: The purpose of the study was to compare the esthetic outcomes of facelift surgery with those of AP and RF. STUDY DESIGN, SETTING, SAMPLE: A 5-year retrospective cohort study was performed on facelift patients treated by a single surgeon...

PURPOSE: Fractional microneedle radiofrequency (FMR) systems are used to treat inflammatory acne and scarring. Nonetheless, few controlled studies have combined this treatment with the traditional ablative fractional laser (AFL). We aimed to assess the safety and efficacy of the combination of FMR and AFL versus AFL alone in treating acne and acne scars. MATERIALS AND METHODS: In this 20-week, randomized, split-face study, 23 Korean patients with facial acne and acne scars underwent FMR and AFL treatments...

BACKGROUND: Facial skin relaxation has become an important part in solving the problem of facial rejuvenation. Minimally invasive or noninvasive skin-tightening procedures have become a trend for facial rejuvenation. Bipolar radiofrequency (RF) is a new option for treating skin relaxation and is more effective than noninvasive surgery without surgical incision. OBJECTIVE: To explore the effect of different bipolar RF powers on the area of the original box, changes of skin and subcutaneous tissue thickness and numbers of fibroblasts in rabbits...

BACKGROUND: Acne scarring is an unfortunate sequela affecting up to 95% of patients with acne and carries profound psychosocial impact. Both nonablative fractional lasers (NAFL) and microneedling with radiofrequency (MNRF) have demonstrated comparable efficacy in the treatment of atrophic acne scars. OBJECTIVE: To determine whether alternating NAFL and MNRF is superior to NAFL alone in the treatment of atrophic acne scars. METHODS AND MATERIALS: This was a prospective, single-center, double-blinded, split-face clinical trial...

OBJECTIVES: CT is the clinical standard for surgical planning of craniofacial abnormalities in pediatric patients. This study evaluated three MRI cranial bone imaging techniques for their strengths and limitations as a radiation-free alternative to CT. METHODS: Ten healthy adults were scanned at 3 T with three MRI sequences: dual-radiofrequency and dual-echo ultrashort echo time sequence (DURANDE), zero echo time (ZTE), and gradient-echo (GRE). DURANDE bright-bone images were generated by exploiting bone signal intensity dependence on RF pulse duration and echo time, while ZTE bright-bone images were obtained via logarithmic inversion...

BACKGROUND: Thermage is a monopolar radiofrequency (RF). It has become an indispensable part of facial and body youthful methods. Although the current device is constantly improving in epidermal cooling techniques and even automatically measures the local impedance value, applying surface anesthesia can take some of the pain away caused by thermage, and the patient's severe pain in the jaw and neck areas is still difficult to resolve. METHODS: The author describes how he uses the combination of the buccal nerve block (BNB) and the superficial cervical plexus block (SCPB) to improve the comfort of the patient's face and neck treatment of patients...

We report the case of a 28-year-old male patient diagnosed with extensive metastatic Ewing sarcoma that affected his facial bones. The patient came to us with left-sided jaw/facial pain that could not be managed successfully through conservative methods. We utilized radiofrequency ablation (RFA) of the left Gasserian (trigeminal) ganglion to alleviate the patient's pain successfully. Although this method is commonly used to treat trigeminal neuralgia, to the best of our knowledge, this is the first documented case where Gasserian ganglion RFA has been successfully used to manage pain in a patient with jaw cancer...

Understanding facial anatomy is a key aspect for successful treatment of age-related changes manifested to facial tissues. Namely, changes to the facial muscles and their connective tissue framework result in an increased soft tissue laxity, leading to wrinkling, sagging, and altered texture. This review elaborates on the use of novel high intensity focused electrical stimulation (HIFES) and Synchronized RF technology to improve facial muscle tone and skin structure, focusing on the technology background and clinical aspects...

Radiofrequency microneedling is a technique that allows energy to be delivered to specified target depths in the skin via needle electrodes and measures temperature and impedance within the tissue. This method of delivery and real-time feedback has increased safety and efficacy, providing clinically significant improvements in skin laxity, rhytids, and cellulite.
