Abstract
in English, Spanish

Essential palatal myoclonus is a rare neurological disorder characterized by involuntary movements of the soft palate musculature causing objective-clicking tinnitus. The palatal myoclonus is classified in two forms, secondary and essential palatal myoclonus. Primary (essential) palatal myoclonus is the most common type in childhood. Normal computed tomography and magnetic resonance guide the diagnosis. Spontaneous resolution usually occurs in the essential type of palatal myoclonus. In this report, we present an 8-year-old child making rhythmic, rapid clicking noises from her throat with spontaneous resolution.

La mioclonía palatina esencial es una entidad otoneurológica rara. Se caracteriza por movimientos involuntarios de los músculos del paladar blando que causan un tinnitus objetivo. La mioclonía del paladar se clasifica en dos tipos: secundaria y primaria (mioclonía palatina esencial); esta última es más frecuente en pediatría. La tomografía computada y la resonancia magnética de cerebro normal orientan al diagnóstico. La mioclonía palatina esencial, generalmente, se resuelve en forma espontánea. Se presenta a una paciente de 8 años de edad con un “clic” rápido en forma rítmica en su boca que cedía en forma espontánea.

Keywords: essential tremor; palatal myoclonus; pediatrics; tinnitus.
