Selective block of grey communicantes in upper thoracic sympathectomy. A feasibility study on human cadaveric specimens.

Sympathetic chain interruption is the gold standard treatment for essential hyperhidrosis. Postoperative compensatory hyperhidrosis, the main reason for patients' dissatisfaction, is reduced by selectively lesioning white and grey rami communicantes (ramicotomy). To develop an endoscopic surgical technique that interrupts only T and T grey rami communicantes to minimize compensatory hyperhidrosis.
