Radiofrequency, as a safe, effective and tolerable treatment option, come into prominence of aesthetic applications in the last period. Radiofrequency devices produce focal thermal damage to the dermis by electric current-generated heat. This focused energy preserves the epidermis and is associated with fewer complications and side effects and quicker recovery time. Contrary to lasers, the effect is independent of chromophores, so they can be used safely in all skin types. Although the results have overall been favorable, many of the studies are nonrandomized, noncomparative trials based on subjective evaluation. The ideal treatment parameters, the energy levels and the number of passes for optimal results have not been determined yet. Radiofrequency applications in face and neck aesthetics are reviewed with the current literature in this article. [ABSTRACT FROM AUTHOR]

Objective: Lower extremity venous insufficiency is a condition in which the flow of venous blood returns to the heart and the normal one-way rotation of the venous blood is reversed. As an alternative to open surgery in varicose veins, non-surgical endovascular procedures and hybrid endovascular procedures have emerged in the last decade. In this study, we aimed to evaluate the mid and long term results of endovenous radiofrequency ablation (RF) as an endovascular method. Methods: Between March 2015 and January 2017, 150 patients who underwent RF with the diagnosis of venous insufficiency were included in our study. 82 patients were female (54.7%), 68 were male (45.3%). The age range was 21-68 years old. Spinal anesthesia was performed in 139 patients and general anesthesia was performed in 11 patients. The RF ablation catheter was inserted into the Great Saphenous Vein (GSV) under the guidance of Doppler USG guided at the appropriate level below the knee. RF ablation was performed after approximately 1 cm distal of the superficial epigastric vein and then a flabectomy was performed. Result: Postoperative 1st 10th day, 1st 6th month and 1st 2nd year controls were performed. In control Doppler USG performed in sixth month, 135 patients (%90) had BSV complete occlusion and in 15 patients (%10) 40% recanalization. Six patients had deep venous insufficiency and 1 patient had perforating venous insufficiency. This patient developed varicose vein stockings in the medial malleolus and venous ulceration (C6) despite intensive medical therapy. Doppler USG performed in the first year of follow-up was 134 patients with GSV full occlusion and 16 patients with 40% recanalization. In the 2 year follow-up, there was no difference in the GSV patency rate between the first year and Doppler USG controls. Conclusion: We evaluated the mid and long term results of radiofrequency ablation in a single center, retrospectively in the treatment of venous insufficiency and varicose veins, which are common in the community. When applied with appropriate indication, radiofrequency ablation success rate is high, complication rate is low and it is also successful in terms of cosmetic results. [ABSTRACT FROM AUTHOR]

Aim: The aim of this study was comparing the radiofrequency energy, bipolar-cautery and suture methods which were used for bleeding control in circumcision operations. Material and Methods: Eighty-three patients, between 1-14 years of age underwent circumcision operation between 2009 and 2011 are included in this randomized, prospective study. Patients were separated into three groups according to the bleeding control method used. Radiofrequency used in Group A (n=23), electro-cauterization used in Group-B (n=26), and sutures applied in Group C (n=34). Results were revealed for operation time, postoperative infection, hemorrhage, edema, and skin opening. Results: Mean age of the patients in general group was 4.92 years (SD: 3.09, range: 1-14), postoperative infection rate was 4% (SD: 1.88), mean edema duration was 6.64 days (SD: 1.29, range: 4-10), and groups were similar for these values. Mean operation duration was 17.41 minutes (SD: 6.04, range: 8-35), and this time was distributed through groups as 12.43 minutes in Group-A, 13.92 minutes in Group-B, and 23.44 minutes in Group C. Statistical analyses revealed that Group-A and Group-B were similar for the operation duration, whereas they were both significantly differed from Group C (p<0.001). Conclusion: Utilization of radiofrequency cauterization in widely applied circumcision operations in childhood is a fast, efficient and reliable method. [ABSTRACT FROM AUTHOR]
