Age-related size reduction of foramina in the cribriform plate

摘要: Anecdotal evidence suggests that the foramina of cribriform plate which transmit cranial nerve I decrease in size with age, but this finding has never been supported quantitative data. It also observed olfactory function declines increasing age. hypothesized closure may be responsible for performance We gathered data to test an age-related decline area. report area patent posterior 1 cm 57 plates from 40 skulls known age and sex. Analyses were performed effects sex, lateralization on The decreases Age is a strong covariate (P value = 0.0025). regression equation is: expected 8.17 - (0.06) Adding variable sex does not contribute significantly > 0.28) model utilizes alone. Nor was there any significant no difference between males females or left right sides. Such associated impaired aged.
