Universidad de Zaragoza (orcid)0000-0001-9372-4267 Influence of Sex and Age on Posterior Semicircular Canal Thickness 2017 Access copy available to the general public Unrestricted 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. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.078 2017 OTORHINOLARYNGOLOGY 14 / 41 = 0.341 2017 Q2 T2 AUDIOLOGY & SPEECH-LANGUAGE PATHOLOGY 6 / 25 = 0.24 2017 Q1 T1 NEUROSCIENCES 194 / 261 = 0.743 2017 Q3 T3 1.222 2017 Medicine (miscellaneous) 2017 Q1 Otorhinolaryngology 2017 Q1 Speech and Hearing 2017 Q1 Sensory Systems 2017 Q2 Physiology 2017 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Tejedor, M.T.
