Pathophysiology of hemifacial hyperhidrosis

Abstract

Thermal facial hyperhidrosis may be often compensatory due to the anhidrotic parts, but little is known on the pathophysiological mechanism. We analyzed it for 14 patients who complained of facial hyperhidrosis by defining the total body sweating patterns using Minor’s starch-iodine test, total skin temperature distribution using infrared thermography, local skin blood flow using laser Doppler flow meter, and magnetic resonance imaging (MRI) to confirm the lesions. Results: The sweating patterns were classified as follows: I.
