Use of Three-Dimensional Imaging to Assess the Effectiveness of Volume as a Critical Variable in Breast Implant Selection.

Background: In breast augmentation, breast base diameter has been recognized as an important variable in implant selection. However, breast implant volume also has a tremendous impact on the final result. Previous methods of preoperative volume determination have been limited to external devices in a bra. Computer-based three-dimensional simulation technology now allows the physician to effectively communicate with the patient preoperatively regarding volume.

Methods: A cohort of 40 consecutive patients underwent routine breast augmentation with either anatomically shaped or round implants. Five methods of preoperative volume determination including the Crisalix three-dimensional computer imaging system (Crisalix Virtual Aesthetics, Lausanne, Switzerland), along with an associated virtual reality tool, were used to assess the preoperative desires of the patients. A postoperative questionnaire was used to assess patient satisfaction with each volume determination method.

Results: Of the 40 patients, 100 percent were satisfied with their result; however, given the opportunity, 12 percent would have chosen a larger implant. The virtual reality tool and external sizers were shown to be the most effective in choosing an implant. The virtual reality tool was judged to be very helpful (62 percent), very accurate (78 percent), and important (88 percent) in helping patients choose their desired implant size.

Conclusion: Prioritizing volume as an implant selection variable in breast augmentation results in a very high rate of patient satisfaction.
