“…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).…”

“…However, the age-dependent evolution of PSC thickness was different in males and females. As can be seen in Table 2 , men aged ≥ 45 years did not show a significant agedependent modification in PSC thickness, but from age 45 years onward PSC thickness decreased faster (0.0180 ± 0.0080 mm/year) than the prevision of Davey et al [2015] for SSC. In females, PSC thickness increased significantly until age 45 years (0.0200 ± 0.0080 mm/year) but it did not show a significant age-dependent modification from age 45 years onwards.…”

“…In view of our findings, age and sex influence the thickness of PSC and SSC differently. An age-dependent reduction in SSC thickness, in both males and females, has been previously reported [Davey et al, 2015]. However, PSC thickness did not significantly evolve with age in young males ( ≤ 45 years) but it decreased from age 45 years onwards.…”

Objective: The aim of this study is to determine whether sex and age influence posterior semicircular canal (PSC) thickness. Methods: This observational study was conducted in 3 tertiary hospitals. The minimal distance between the PSC and the posterior cranial fossa (PSC thickness) was estimated by thin-section multidetector row computed axial tomography (CAT) scan of the temporal bones. Nonselected consecutive patients of all ages (607 temporal bones) were considered. Results: A significant effect was only detected for sex (F = 5.418, p = 0.020); PSC thickness showed a higher mean value in women (mean difference ± SE: 0.224 ± 0.096 mm). A significant and negative r value was detected for males aged >45 years (-0.173, p = 0.026); in that group of patients, PSC thickness decreased as age increased (0.018 ± 0.008 mm/year). For females aged ≤45 years, a significant and positive r value was found (0.198, p = 0.022); in that group, PSC thickness increased as age increased (0.020 ± 0.008 mm/year). Conclusions: PSC thickness did not significantly evolve with age in young males (≤45 years) but it decreased from age 45 years onwards. On the other hand, PCS thickness increased with age in women until the age of 45 years and it did not significantly change in older females.

Practice guideline: Cervical and ocular vestibular evoked myogenic potential testing

et al. 2017

View full text Add to dashboard Cite

Objective: To systematically review the evidence and make recommendations with regard to diagnostic utility of cervical and ocular vestibular evoked myogenic potentials (cVEMP and oVEMP, respectively). Four questions were asked: Does cVEMP accurately identify superior canal dehiscence syndrome (SCDS)? Does oVEMP accurately identify SCDS? For suspected vestibular symptoms, does cVEMP/oVEMP accurately identify vestibular dysfunction related to the saccule/utricle? For vestibular symptoms, does cVEMP/oVEMP accurately and substantively aid diagnosis of any specific vestibular disorder besides SCDS?Methods: The guideline panel identified and classified relevant published studies
