Turkey wing vessels were used to create aneurysm models with patient-specific geometry. Three simulation models (middle cerebral artery aneurysm clipping via a pterional approach, anterior cerebral artery aneurysm clipping via an interhemispheric approach, and basilar artery aneurysm clipping via an orbitozygomatic pretemporal approach) were subjected to face, content, and construct validity assessments by experienced neurosurgeons (n\u00a0=\u00a08) and neurosurgery trainees (n\u00a0=\u00a08).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      Most participants scored the model as replicating actual aneurysm clipping well and scored the difficulty of clipping as being comparable to that of real surgery, confirming face validity. Most participants responded that the model could improve clip-applier-handling skills when working with patients, which confirms content validity. Experienced neurosurgeons performed significantly better than trainees on all 3 models based on subjective (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u00a0=\u00a0.003) and objective (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u00a0&lt;\u00a0.01) ratings and on time to complete the task (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u00a0=\u00a0.04), which confirms construct validity.
