Recommended surgical approach and approach side * after presenting conventional CTA images (2D and screen 3D) or reconstructed 3D-VR images, evaluated using Fisher’s exact test, assuming a p-value <0.05 to be significant.
| Recommendations, n (%) | CTA (n = 260) | 3D-VR (n = 260) | p-Value |
|---|---|---|---|
| recommended surgical approach: | |||
| supraorbital subfrontal | 76 (29) | 48 (18) | 0.001 |
| pterional | 93 (36) | 83 (32) | (significant) |
| extended pterional | 91 (35) | 129 (50) | |
| recommended approach side: | |||
| right | 135 (52) | 149 (57) | 0.25 |
| left | 125 (48) | 111 (43) | (not significant) |
