ABSTRACT

Published: 20-09-2016 traditional Wise pattern inferior pedicle technique. Methods: Inferior pedicle reduction
mammoplasty was performed using either a Wise pattern or modified Robertson skin incision.
3D photography and analysis were done at 1-3 months and 6-12 months postoperatively.
Key words: Results: There were 14 breasts in the modified Robertson group (ROB) and 24 breasts in
3D photography, the Wise pattern group (WISE). There were no significant differences in demographic data
mammometrics, or amount of tissue resected. At 6-12 months, the modified Robertson cohort demonstrated
modified Robertson, increased superior pole fullness (62.9% ROB vs. 58.3% WISE, P = 0.05). The Wise cohort,
Wise pattern, however, maintained greater maximum breast projection (5.52 cm ROB vs. 6.54 cm WISE,
reduction mammoplasty 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 cm ROB vs. +2.59 cm WISE, P = 0.77); however, the final size

in the modified Robertson group while the Wise pattern group demonstrated greater medial
pole fullness and maximum breast projection.

Reduction mammoplasty is one of the most commonly results, even in large reductions; [2,6,7] however, critics
