“…In case 2, the patient was 52 years old when she presented the crises and received the diagnosis of SSCDS. As it can be observed, case 2 presents similar results to the study that observed a decrease in bone coverage of the superior semicircular canal after the age of 45, but in case 1 the pathology was diagnosed with a lower age than the one found by the author 13 .…”

The Superior Semicircular Canal Dehiscence Syndrome (SSCDS) is characterized by bone wear layer overlying the superior semicircular canal. Common symptoms of SSCDS the presence of vertigo associated with nystagmus induced by intense sound stimuli or changes in intracranial pressure or middle ear. The aim of this study is to describe the audiological and vestibular findings of two patients diagnosed with Superior Semicircular Canal Deiscence Syndrome, with confirmed diagnosis by computed tomography. Meatoscopy, anamnesis, pure tone audiometry and vocal followed by the acoustic impedance measurements, audiometric Weber, research Tulio phenomenon and Valsalva maneuver, performed by the same researcher in one session were held. Air-bone gap were observed, type A tympanometric curve and acoustic reflex. The air-bone gap is presented with greater amplitude at low frequencies. Hearing complaints were not reported by patients as the first symptoms. Weber showed lateralization in both cases, confirming the presence of gap. The Thulium phenomenon is positive for vertigo in both cases. The Valsalva maneuver showed a change in only one case.

São sintomas comuns da SDCSS a presença de vertigem associada à nistagmos induzidos por estímulos sonoros intensos ou por modificações das pressões intracraniana ou da orelha média. O objetivo deste trabalho é descrever os achados audiólogi-cos e vestibulares de dois pacientes com diagnóstico de Síndrome da Deiscência do Canal Semicircular Superior, com diagnóstico confirmado por meio de tomografia computadorizada. Foram realizadas meatoscopia, anamnese, audiometria tonal e vocal seguida das medidas de imitância acústica, Weber audiométrico, pesquisa do fenômeno de Túlio e manobra de Valsalva, realizados pela mesma pesquisadora em uma única sessão. Foram observados gap aéreo-ósseo, curva timpanométrica tipo A e reflexos acústi-cos presentes. O gap aéreo-ósseo apresenta-se com maior amplitude nas frequências baixas. As queixas auditivas não foram relatadas pelas pacientes como os primeiros sintomas. O Weber mostrou lateralização, nos dois casos, confirmando a presença de gap. O fenômeno de Túlio apresentou-se positivo para vertigem em ambos os casos. A manobra de Valsalva apresentou alteração em apenas um caso.

“…A 10% decrease in thickness (0.1 mm) over 40 years of life has been reported in the bone overlying the superior semicircular canal. 10,13,24 The multiple linear regression model did not show sex as an independent predictor factor. Large-sample studies analyzing the interaction term of sex 3 age are needed to further explore this relationship.…”

“…Despite the low rate of bone turnover of the otic capsule, it is known that age has a negative effect on the thickness of bone covering the superior semicircular canal (10,11). A retrospective review of high-resolution temporal bone CT scans demonstrated that the thickness of bone over the superior semicircular canal decreases by 0.005 mm per year with increasing age (10).…”

Influence of Aging and Menopause in the Origin of the Superior Semicircular Canal Dehiscence

Abstract: Our data support the hypothesis that there is a slight osteopenia of the roof of the superior semicircular canal associated with aging, and this effect seems to be more pronounced in menopausal women.
