Letter to the Editor: Percutaneous Chemical Dorsal Sympathectomy for Hyperhidrosis
25 January 2012 (online)
We read with interest the article of Dr. Ebrahim . The use of sympathetic block to treat palmar hyperhidrosis was tested in the past. 2 series were published  . The group of Adler noticed a 10% recurrence at 4 months. A subsequent follow-up of their cases  revealed 40% recurrences and the method of treating palmar hyperhidrosis by phenol blocks was abandoned by this group of authors. In another study of chemical lumbar blocks performed to treat plantar hyperhidrosis , recurrence occurred in 89.9% of patients at 6–18 months. Taking into consideration these medium-term results, we wonder at the overall merits of chemical blocks over surgery for the treatment of primary hyperhidrosis. Dr. Ebrahim has a 1-year follow-up of his patients and already noticed 10% recurrences. We urge him to follow his patients for another year and publish at that time his results.
