Thermophysiologic anthropometry of the face in Homo sapiens

Standard clinical thermographic practice has been to regard a side-to-side skin surface temperature difference of 0.5 degrees C or greater as indicative of a clinically significant disorder when such a difference is observed for the contralateral sides of the face. Prior to this time this standard relied upon empiric observation and cumulative experience. This paper provides the first published documentation clearly supportive of this long-standing clinical practice.
