Essential palatal tremors in a child

An 8-year-boy presented with a history of “clicking sounds” in both ears on opening his mouth; this was present for two months. The ‘click’ was associated with abnormal pressure sensation in the ears and would disappear on mouth closure and during sleep. Oral examination revealed the rhythmic, repetitive, bilateral symmetrical bilateral movement of the soft palate and uvula [Video available at www.jpeds.com]. The rest of the neurological examination and magnetic resonance imaging (MRI) brain were normal.
