Abstract
Augmented reality (AR) technologies are being actively introduced into medicine. AR can be used as a navigation tool in neurosurgery. The purpose of our study is to evaluate the accuracy of placement of external ventricular drainage, the size of the incision and the duration of this manipulation in an animal model using AR navigation and without its use. A CT scan of an animal model (ram's head) was performed, the results were segmented and loaded into AR-glasses. Participants in the experiment are divided into 2 groups of 5 people each. In the main group, ventricular drainage was placed using AR navigation, in the control group without its use. The average incision size in the non-AR group was 29.58 ± 1.566 mm. In the AR group 29.42 ± 1.279 mm. The differences in the two groups are statistically insignificant (p=0.797). In the AR group, the mean operative time was 10.26 ± 1.121 min. In the group without AR use 13.64 ± 1.588 min. The differences between the groups are statistically significant (p<0.05). In the AR group, drainage was inserted into the ventricle in 47 of 50 cases (94%). In the group without the use of AR in 40 cases out of 50 (80%). These differences are statistically significant (p=0.037). AR navigation does not affect the size of the incision, but increases the accuracy of drainage placement and reduces the duration of the procedure. This shows the possibility of using this technology in clinical practice, however, additional research on the use of AR in phantom models is required.
