RESUMEN El tinnitus se presenta en forma crónica en alrededor del 10% de los adultos, siendo el 4% de estos casos tinnitus pulsátil (TP). El TP se caracteriza por ser rítmico y sincrónico al latido cardiaco. Existen múltiples causas descritas, pero en un grupo importante de casos, no se logra objetivar su origen. Nuestro objetivo es presentar casos de dehiscencia del canal semicircular superior (DCSS) como causa de tinnitus pulsátil y su estudio. Se presentan dos pacientes evaluadas por tinnitus pulsátil. En ambos casos se descartan causas sistémicas, ECO doppler carotídeo sin alteración, angio TAC y RNM sin hallazgos. En reconstrucción de Pöschl se sospecha DCSS, por lo que se estudia con potenciales miogénicos evocados cVEMP y oVEMP con disminución de umbral y respuesta aumentada en oído afectado. En los casos expuestos el tinnitus aparece como síntoma único asociado a la presencia de DCSS, que fue confirmada con estudio imagenológico y VEMPs. El estudio con angio TAC permite pesquisar diversas causas asociadas. Los VEMPs confirman el diagnóstico, teniendo el oVEMP mayor sensibilidad. Como conclusión la DCSS es una entidad a tener presente como diagnóstico diferencial del tinnitus pulsátil y ante su sospecha se debe explorar con VEMPs.
ABSTRACT Tinnitus occurs chronically in about 10% of adults, being pulsatile tinnitus a 4% of these cases (TP). TP is characterized by being rythmic and sychronous to the heart beat. There are many described causes, but in a significant group of cases it is not possible to determine its origin. Our aim is present clinical cases of superior semicircular canal dehiscence (SSCD) as the cause of pulsatile tinnitus and its study. Clinical cases: Two patients present pulsatile tinnitus in her right ear. System causes were discarded, normal Carotid Doppler ultrasonography, Anglo CT scan and MRI without findings. In Pöschl reconstruction SSCD can be observed. Evoked myogenic potentials (VEMPs) by suspicion of SSCD Syndrome, cVEMP and oVEMP with a elevated amplitudes and lower thresholds ipsilateral response. In the cases exposed, tinnitus appears as a single symptom associated with the presence of SSCD which was confirmed with imaging studies and VEMPs. The AngioTAC allows to investigate several associated causes. The VEMPs confirm the diagnosis, with oVEMP having a greater sensitivity. The SSCD is an entity to have in my mind as a differential diagnosis of pulsatile tinnitus and, if suspected, should be explored with VEMPs.
