Background: In functional endoscopic sinus surgery, the intricate anatomy and the use of minimally invasive endoscopic techniques may hinder comprehensive patient understanding in the informed consent process. Aims/Objectives: Evaluation of the impact of personalized 3D CT computed tomography (CT) imaging supplementing informed consent in sinus surgery. Material and Methods: In this prospective randomized study, patients scheduled for paranasal sinus surgery were allocated to standard informed consent using two-dimensional (2D) CT imaging or to counseling supplemented with individualized three-dimensional (3D) CT reconstructions. All patients received a questionnaire prior-and postsurgery to assess disease comprehension, perception of risks and benefits, and satisfaction with the informed consent process. Results: Twenty-two patients were included, with equal distribution between groups. The 3D group demonstrated significantly greater understanding of expected recovery and recurrence (p = 0.03) and improved knowledge transfer (p = 0.04). Postoperatively, the 3D group reported significantly higher understanding scores (4.50 vs. 2.73). The composite outcome-encompassing disease understanding, surgical comprehension, and overall satisfaction-was superior in the 3D group (16.00 vs. 11.64; p < 0.01). Conclusions and Significance: Patient-specific 3D CT reconstructions may enhance informed consent in sinus surgery, improving comprehension, shared decision-making, and satisfaction with preoperative counseling.
