[Measurement by a numerical approach of breast volume].

INTRODUCTION Breast surgery, regardless of the type of procedure, requires a symmetrical result. However, this outcome is currently dependent on the surgeon's experience and subject to their subjectivity. Our study aims to investigate the correlation between the weight of breast gland resection and the volume variation measured by a portable 3D camera, adjusted for breast density measured electronically.

MATERIALS AND METHODS Thirty patients who underwent bilateral breast reduction were included in the study. Each patient had her breast volume measured using a 3D camera (GOPRO by Creaform) during the preoperative consultation and again four months postoperatively. For each patient, breast density was measured using the MyotonPro device.

RESULTS Analysis of the correlation between the resection weight and pre- and postoperative volume variation revealed a coefficient of determination r2 of 0.822 (95% CI: 0.713-0.892). Adjustments based on the parameters measured by the MyotonPro did not appear to influence the correlation. Our model indicates that for a resection weight≥500g, there is a volume variation of 666mL, with a sensitivity of 85.3% and a specificity of 86.4%.

CONCLUSION There is a strong correlation between the resection weight and the volume variation measured by the 3D camera, with no influence from breast density. The routine use of a 3D camera would allow plastic surgeons to better plan each surgery and optimize our results.
