Descriptive statistics of olfactory sulcus measures, both as absolute measures and as measures in relation to the maximum inner coronal diameter of the anterior skull
| Olfactory Sulcus Measure | Controls (n = 8) | IA Patients (n = 16) | ||
|---|---|---|---|---|
| Left | Right | Left | Right | |
| Absolute length (mm) | 28.6 ± 5.0 | 28.9 ± 6.1 | 28.1 ± 6.9 | 30.6 ± 1.7 |
| Relative length (%) | 28.4 ± 5.0 | 28.9 ± 5.9 | 27.6 ± 6.7 | 29.9 ± 6.3 |
| Maximum depth (mm) | 9.9 ± 1.5 | 10.2 ± 1.1 | 9.1 ± 2.4 | 9.8 ± 2.1 |
| Relative depth (%) | 9.2 ± 1.9 | 10.1 ± 1.4 | 8.8 ± 2.4 | 9.6 ± 2.0 |
| Depth in the PPTE (mm) | 8.8 ± 1.5 | 8.9 ± 1.4 | 5.0 ± 3.3 | 6.4 ± 3.4 |
| Relative depth in the PPTE (%) | 9.3 ± 1.2 | 8.8 ± 1.4 | 4.9 ± 3.3 | 6.4 ± 3.4 |
| Depth >0 in the PPTE (mm)* | — | — | 5.7 ± 2.9 | 7.5 ± 2.4 |
| Relative depth >0 in the PPTE (%)* | — | — | 5.6 ± 2.8 | 7.3 ± 2.5 |
Note.—Data are the mean ±SD.
* Only the depth of the olfactory sulcus in the PPTE >0 was taken into consideration (in two IA patients, the olfactory sulcus in the PPTE was not visible).
