The nonablative radiofrequency is a procedure commonly used for the treatment of skin laxity from an increase in tissue temperature. The goal is to induce thermal damage to thus stimulate neocollagenesis in deep layers of the skin and subcutaneous tissue. However, many of these devices haven't been tested and their parameters are still not accepted by the scientific community. Because of this, ...

Management of pain from skeletal metastases is notoriously difficult. Case reports and case series have described radiofrequency ablation of the obturator nerve branches to the femoral head for treatment of intractable hip pain. Ablation of the obturator branches to the femoral head is technically difficult because of bony and vascular anatomy, including close proximity of the femoral vessels. ...

BACKGROUND Intercostal nerve blocks offer short-term therapeutic relief and serve as a diagnostic test for intercostal neuralgia. This original case report demonstrates the efficacy of radiofrequency ablations for long-term pain relief of intercostal neuralgia. To date, there have been no studies that demonstrate the efficacy of thermal conventional intercostal nerve radiofrequency ablations fo...

BACKGROUND Remote heating of metal located near a radiofrequency ablation source has been previously demonstrated. Therefore, ablation of cardiac tissue treated with metallic nanoparticles may improve local radiofrequency heating and lead to larger ablation lesions. We sought to evaluate the effect of magnetic nanoparticles on tissue sensitivity to radiofrequency energy. METHODS AND RESULTS A...

Chronic tonsillitis is a common disease, and several different surgical techniques are used to treat this condition. In recent years, techniques such as radiofrequency ablation and coblation have been commonly used for tonsil surgery. In this report, we present the cases of two pediatric patients who developed ptosis, miosis, and enophthalmos (Horner syndrome) after radiofrequency ablation for ...

OBJECTIVES To describe the various techniques that have been developed for application of radiofrequency ablation in the palliative treatment of recurrent and advanced head and neck malignant tumors. DESIGN Case series with a follow-up of 3 to 18 months. SETTING Faculty practice, research protocol, tertiary care academic medical center. PATIENTS Fifteen treatments were administered over a...

Xanthelasma palpebrarum is the most common form of xanthoma, which is mostly located on the eyelids. Various treatment options are available. All have applications, and none produce satisfactory outcomes. Radiofrequency thermal energy induces ionic agitation with vaporization at the cellular level in tissues. It uses a controlled radiofrequency current to reduce the tissue volume in a precise a...

BACKGROUND Failure to achieve properly localized, permanent tissue destruction is a common cause of arrhythmia recurrence after cardiac ablation. Current methods of assessing lesion size and location during cardiac radiofrequency ablation are unreliable or not suited for repeated assessment during the procedure. MRI thermography could be used to delineate permanent ablation lesions because tiss...

STUDY OBJECTIVE To compare the hemodynamic changes that occur during laparoscopic radiofrequency ablation of liver metastases with those occurring during laparoscopic ultrasound hepatic examination alone. DESIGN Prospective, observational study. SETTING Operating rooms of a university-affiliated hospital. PATIENTS 40 ASA physical status 2 and 3 patients with liver metastases. INTERVENTI...

BACKGROUND Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation. Radiofrequency ablation is the most common method, and cryoballoon ablation is the second most frequently used technology. METHODS We conducted a multicenter, randomized trial to determine whether cryoballoon ablation was noninferior t...
