The Minor's test in Frey syndrome treated with botulinum toxin: Methodology and efficacy.

ABSTRACT

In this paper, we aimed at methodologically presenting a video-case of Frey Syndrome occurred after parotidectomy, assessed by means of Minor's Test and treated with intradermic botulinum toxin A (BoNT-A) injection. Although largely described in the literature, a detailed explanation of both the procedures has not been previously elucidated. In a more original approach, we also highlighted the role of the Minor's test in identifying the most affected skin areas and new insight on the patient-tailored approach provided by multiple injections of botulinum toxin. Six months after the procedure, the patient's symptoms were resolved, and no evident signs of Frey syndrome were detectable through the Minor's test.
