Table 2 The correlations between the depth of the cribriform, orbital floor to ethmoid roof height, orbital floor to cribriform plate height, and the angle formed by the lateral lamella of the cribriform plate and the continuation of the horizontal plane passing through the cribriform plate (assessed by the Pearson’s correlation coefficient, r).
