Abstract:
Purpose:Breast volume is an important factor in breast reconstruction; however, the surgeon is expected to deliver the volume expectation with his aesthetic inspiration. Therefore, objective volumetry must be developed. This study aimed to conduct an MRI-based breast volumetric analysis. With periodic analysis of 2-stage breast reconstruction, we suggest the possibility of clinical use of breast volumetry in implant volume prediction.
Methods:This retrospective study included 140 patients who underwent unilateral 2-stage breast reconstruction (tissue expander followed by implant insertion) between January 1, 2017 and December 31, 2019. The MRI image was converted into a 3-dimensional image with a reconstruction program (A-VIEW, Coreline Soft). MRI image was obtained before the surgery and then at 1, 3, 6, 12, and 24 months postoperatively. The volume was automatically calculated.
Results:Compared with the preoperative volume, maximized volume and differences were noted at 1 month and minimized at 1 year. The correlation between MRI-based preoperative breast volumetry and the mastectomy specimen volume was 0.611. Volume difference between the MRI-based preoperative state and the implant volume showed a minimal difference at 1 year. The final implant size prediction formula was calculated using the 1-year postoperative volume (P < 0.001, R 2= 0.594).
Conclusion:To avoid breast reconstruction based solely on the surgeon’s subjective assessment, MRI-based breast volumetry could be a useful method to develop more scientific and objective breast reconstruction planning. We suggest a volume prediction formula that describes the relationship between the postoperative breast volume and the final breast implant size.
