Phenol With Fluoroscopy Guided Radiofrequency Ablation of T2-T3in Palmar Hyperhidrosis.

Primary hyperhidrosis is a disorder characterized by excessive and chronic sweating in the absence of a sweating trigger. The disorder can be severe and interfere with normal daily activities of the patients. The gold-standard treatment in severe cases of hyperhidrosis is thoracoscopic sympathectomy betweenT2 and T4. These procedures are regularly performed in surgical units under general anaesthesia which needs special anesthetic considerations which is complex and associated with a lot of complications. Radiofrequency ablation of the sympathetic chain for treatment of hyperhidrosis is considered alternative to thoracoscopic sympathectomy. The procedure is safe, inexpensive and done under sedation with local anaesthesia in an outpatient setting, but its success rate is still significantly lower than endoscopic sympathectomy. The purpose of this study is to determine whether adding phenol 6% in a mixture with glycerin will increase the efficacy of fluoroscopy guided radiofrequency ablation of T2, T3 sympathetic ganglia in hyperhidrosis in comparison to surgery without significant side effects to provide safe and effective method rather than surgery.
