Distribution of the height of the ethmoid roof with respect to asymmetry and symmetry in the sample (relative values in parentheses).
| | Male | Female | Total (male and female) |
| Lower right ethmoid roof | 107 (.28) | 53 (.2) | 160 (.25) | Lower left ethmoid roof | 38 (.1) | 23 (.09) | 61 (.09) |
| Total asymmetry (lower right or left ethmoid roof) | 145 (.38) | 76 (.29) | 221 (.31) |
| Symmetry | 236 (.62) | 187 (.71) | 423 (.66) |
| Total (asymmetry and symmetry) | 381 | 263 | 644 |
