Three-Dimensional Imaging for Sinus Surgery Informed Consent

Abstract

Objective: 1) Compare the efficacy of using standard 2-dimensional computed tomography (CT) and magnetic resonance imaging (MRI) against 3-dimensional reconstruction during the informed consent process of sinus surgery. 2) Determine whether 3D visualization technology affects patient anxiety prior to sinus surgery.

Method: A randomized, controlled prospective study of patients undergoing sinus surgery was conducted at a tertiary academic center from 2011-2012. Patients were assigned to receive preoperative informed consent with the assistance of 2-dimensional CT/MRI or 3D reconstruction. Questionnaires were administered and compared to assess understanding, satisfaction, and anxiety during the process.

Results: Thirty-four patients were enrolled in this study. There was no significant variation of age, gender, or education level between the groups. The 3D reconstruction group demonstrated significant improvement in the perceived understanding of their condition, the operation, and the potential complications from the procedure as compared to the 2-dimensional CT/MRI group (P < .05). Patients in the 3D reconstruction group were also more satisfied with the informed consent process as a whole. Preoperative anxiety did not vary significantly between the groups.

Conclusion: Three-dimensional reconstruction technology is an effective tool to improve patient understanding and satisfaction during the informed consent process prior to sinus surgery.
