Localized facial flushing in infancy. Auriculotemporal nerve (Frey) syndrome

Familial Auriculotemporal Nerve (Frey) Syndrome

“…Frey syndrome usually manifests during infancy, around the time of solid food introduction. Vigorous chewing elicits a stronger stimulation of the parotid gland than does the sucking of formula feeds, as was noted in our patients (6). Some of the commonly reported food triggers are citrus fruits, apple, green beans, carrots, and candy.…”

Infantile Frey syndrome

“…IFS can be unilateral or bilateral 3. Unilateral forms are thought to be caused by perinatal trauma to parasympathetic branches of the auriculotemporal nerve associated with obstetrics instrumental delivery at the time of birth 5 6. A national retrospective study found that visible marks at birth following a traumatic instrumental delivery were reported in 68% of patients with IFS like the case described in this report 3.…”

Frey Syndrome

“…Bilateral forms occur exceptionally in adults, mainly in the context of bilateral surgery, and are more frequent in the pediatric setting. 4,[11][12][13][14][15][16][17][18] In our series, unilateral forms were statistically significantly more highly associated with traumatic instrumented delivery compared with idiopathic bilateral forms. Forceps and spatula deliveries were both associated with traumatic lesions.…”
