"When patients see what the surgeon sees": 3D imaging creates new understanding in preoperative counseling for...

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.

Evaluation of the impact of personalized 3D CT computed tomography (CT) imaging supplementing informed consent in sinus surgery.

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.

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).

Patient-specific 3D CT reconstructions may enhance informed consent in sinus surgery, improving comprehension, shared decision-making, and satisfaction with preoperative counseling.
