2. Use of 3D simulation Currently 3D image simulation is used during the preoperative consultation as a tool to help patients visualize the results of surgical procedures such as breast augmentation.

3. Clinical Question  Are patients satisfied with the information provided by 3D image simulation after having seen the actual results of surgery?

4. Study Design Control Group Study Group n=36 n=40  Control Group: Photos of average results shown to patients  Study Group: 3D simulations of possible results shown to the patients This prospective, randomized study compared patient satisfaction with information provided during the preoperative consultation for breast augmentation. In our study we used the Crisalix 3D system

5. Method Three months following surgery a self- administered questionnaire was given to the patients to evaluate their satisfaction with the information provided during the preoperative evaluation. 123 4 Very Satisfied Very Dissatisfied Somewhat Dissatisfied Somewhat Satisfied

6. Method: Basic Demographic Information  Age  Weight  Height  Breast implant size Body mass index (BMI) was calculated from the patient’s weight and height

7. Results VariablesControl Group (Mean ± SD) Study Group (Mean ± SD) P Age31±630±7 >0.05 Body Mass Index21±221±3 >0.05 Implant size (cc)355±50350±41 >0.05 No statistically significant difference between the groups (p>0.05)

Results Questionnaire Item Control Group Dissatisfied (Very/Somewhat) Study Group Dissatisfied (Very/Somewhat)P How will I look5%25% <0.05 Accuracy of info5%25% <0.05 Predicted outcome5%25% <0.05 After having had their surgery, patients reported a significantly higher dissatisfaction with the information provided by 3D simulation, in spite of having received information regarding the limitations of 3D simulations 3D simulation vs. actual result

9. Results Pre-Op Post-Op 3D Simulation Right Implant:340cc, Left Implant:325cc Right Implant:400cc, Left Implant:375cc The perfect round contour produced by the simulation is inaccurate and misleading, since tissues respond in different ways to placement of implants Pre-Op Post-Op 3D Simulation

10. Conclusion After having had their surgery, patients reported a higher percentage of dissatisfaction (25%) with the information provided by 3D simulation. The limitations of such imaging programs should be well discussed with patients prior to surgery. 3D simulation vs. actual result
