Aim: The advent of 3D photoimaging and mammometrics has allowed for quantitative, volumetric breast analyses. This study uses 3D photoimaging and mammometrics to compare the postoperative morphometric outcomes of the modiifed Robertson technique to the more traditional Wise patt inferior pedicle technique. Methods: Inferior pedicle reduction mammoplasty was performed using either a Wise patt or modiifed Robertson skin incision. 3D photography and analysis were done at 1-3 months and 6-12 months postoperatively. Results: There were 14 breasts in the modiifed Robertson group (ROB) and 24 breasts in the Wise patt group (WISE). There were no signiifcant differences in demographic data or amount of tissue resected. At 6-12 months, the modiifed Robertson cohort demonstrated increased superior pole fullness (62.9%ROB vs. 58.3%WISE, P=0.05). The Wise cohort, however, maintained greater maximum breast projection (5.52 cm ROB vs. 6.54 cm WISE, P=0.01) and increased medial pole fullness (29.6%ROB vs. 46.9%WISE, P<0.01). There was no difference in tissue shifting from the superior pole to the inferior pole over time (+3.36 superior pole%ROB vs.+1.42 superior pole%WISE, P=0.28). Areola surface area increased equally in both cohorts (+3.08 cm2 ROB vs.+2.59 cm2 WISE, P=0.77);however, the ifnal size of the areola was greater in the modiifed Robertson cohort (26.9 cm2 ROB vs. 21.6 cm2 WISE, P<0.01). Conclusion:Using 3D mammometrics, we found increased superior pole fullness in the modiifed Robertson group while the Wise patt group demonstrated greater medial pole fullness and maximum breast projection.
