Abstract

Objective tinnitus can have many different etiologies, palatal myoclonus being one of the less frequent. This type of tinnitus is generated by involuntary rhythmic contraction of the soft palate, which generates an audible click for the patient and for the explorer.

Botulinum toxin achieves temporary muscle paralysis through presynaptic inhibition of the acetylcholine level at the neuromuscular union.

We present a patient with long-term objective tinnitus, along with this patient's response to botulinum toxin injection.

Keywords:
Objective tinnitus
Palatal myoclonus
Botulinum toxin
Resumen

El acúfeno objetivo o somatoacúfeno puede presentar múltiples etiologías, siendo una de las más infrecuentes la mioclonía palatal generada por la contracción rítmica e involuntaria del paladar blando que genera un click audible por el enfermo y el explorador.

La toxina botulínica genera una parálisis temporal a nivel muscular mediante la inhibición presináptica de la acetilcolina a nivel de la unión neuromuscular.

Presentamos el caso de una paciente con un acúfeno objetivo de larga evolución y su respuesta a la inyección con toxina botulínica.

Palabras clave:
Acúfeno objetivo
Mioclonía palatal
Toxina botulínica
