Improving Volumetric Symmetry in Reduction Mammoplasty Using Intraoperative 3-Dimensional Photogrammetry.

Area of Science:

• Plastic Surgery
• Surgical Technology
• Medical Imaging

Background:

• Reduction mammoplasty aims for breast symmetry, traditionally relying on subjective measurements.
• Objective intraoperative volumetric assessment is lacking, despite the utility of 3D imaging in planning and evaluation.
• Existing intraoperative methods lack rigorous validation.

Purpose of the Study:

• To evaluate the Vectra H2 3D photogrammetric imaging system for intraoperative use in reduction mammoplasty.
• To determine if objective intraoperative volumetric data improves postoperative breast volume symmetry.

Main Methods:

• A comparative study of 100 reduction mammoplasty patients (supero-medial pedicle, wise pattern).
• Group A (control, n=50) used traditional methods; Group B (intraoperative 3D, n=50) used Vectra H2 3D photogrammetry.
• Volumetric symmetry was assessed at 3-month postoperative follow-up.

Main Results:

• No significant differences in demographics, resection weight, or complications between groups.
• Mean 3-month postoperative volumetric differences were 5.8% ± 3.0% (Group A) vs. 2.9% ± 1.5% (Group B).
• The improvement in volumetric symmetry in the intraoperative 3D group was statistically significant (p<0.05).

Conclusions:

• Intraoperative 3D photogrammetry significantly enhances volumetric symmetry after reduction mammoplasty.
• The technique aids in identifying outliers, leading to superior symmetry.
• Validated 3D photogrammetry offers an objective tool for improving surgical outcomes in breast reduction procedures.
