“…There are other physiologic measures that have been reported or could be conceived of in the future but were not included in the current diagnostic criteria since they are not commonly available or standardized. Some examples include power reflectance [33], pulsatile oscillations of the eye [53] and pulsatile movements of the tympanic membrane [10,21]. Such diagnostic adjuncts could be considered as supportive evidence for SCDS in centers that have expertise in these recordings and may be promising avenues for further research.…”

“…Este trabajo proporcionó evidencia fundamental para la comprensión de los mecanismos fi-siopatológicos detrás de este signo tan frecuentemente atribuido a los pacientes con estas dehiscencias. En la video-otoscopia pudieron observarse los movimientos de la membrana timpánica en sincronía con el pulso arterial y que, según los autores, podría tener su origen en dos hechos concomitantes: la alteración en la transmi-sión de la presión intracraneal al oído medio a través del defecto en el tegmen tympani, unida a la propagación de la onda de pulso a la endolinfa a través de la dehiscencia del canal 18 . Handzely cols., en 2018, reiteraron la importancia de la realización de tomografía computarizada para buscar dehiscencias del canal previo al tratamiento quirúrgico de una dehiscencia del tegmen, debido a que, tras la intervención de tegmen mediante craneotomía vía temporal, una dehiscencia del canal semicircular superior asintomática no detectada podría tornarse sintomática.…”

“…At otomicroscopy, pulsation at the level of the left attic eardrum had disappeared, as previously described. 10 At the 2 years follow–up, the patient was still devoid of further episodes of imbalance, vertigo or meningitis, with no significant hearing changes.…”

“…8 Superior semicircular canal dehiscence (SSCD) was identified by Minor et al in 1998 9 as a syndrome of vertigo and oscillopsia. The prevalence rates in cadaveric temporal bone studies range from 0.4% to 0.7% 10,11 and from 2% to 13% in computed tomography (CT) studies 12,13 with the majority of patients being asymptomatic. Symptomatic patients will usually present with only cochlear, only vestibular or vestibulocochlear signs and symptoms.…”
