Thermographic study of palmar and facial skin temperature of hyperhidrosis patients before and after thoracic sympathectomy.

Abstract

These findings demonstrate that the T2 segment is the key source of sympathetic innervation to the hand and that the T2 segment contributes only trivial sympathetic innervation to the face. The results of the present thermography studies offer descriptive information about the autonomic innervation of the upper thoracic sympathetic trunk.
