Abstract
Frey syndrome classically causes gustatory sweating and facial flushing. We describe
2 cases in which medical thermography was used to investigate the symptoms. Images
were taken after patients chewed a sialagogue and 2 weeks later they were given injections
of botulinum toxin A. Images taken 4 weeks after treatment showed a considerable reduction
in sweating and facial flushing, which was supported by the results of quality of
life questionnaires completed before and after treatment. Medical thermography is
much cleaner than the Minor's starch iodine test. It identifies areas of gustatory
sweating, changes in temperature, and vascular changes, which potentially enable treatment
to be targeted accurately.
