Objective: To investigate the effect of three-dimensional (3D) printer technology on transsphenoidal endoscopic pituitary surgery.
Material and Method: Preoperative Paranasal CT images of 12 patients who were applied transsphenoidal endoscopic surgery due to Pituitary
Adenoma were printed with 3D printer after reconstruction and measurements were made by surgical team on bone structure and endoscopeguided
simulation was made.
Findings: Average operation duration of the patients who had 3D print modeling was 106±13.52 minutes and operation lasted 152±24.14 minutes
in the patients who didn't have modeling. Average hospitalization duration of the patients who had 3D print modeling was 3±1.42 days and
hospitalization duration was 6±2.64 days in patients without modeling. Hospitalization and operation durations of the patients who were operated
with 3D print modeling were detected shorter and found to be statistically signicant (p<0.01).
Result: Preoperative planning with 3D modeling increased the mastery on individual surgical anatomy and decreased complication rate, operation
duration and hospitalization duration.
