Comparative Analysis of Lower Island Flap Transposition (LIFT) in Wise-Pattern Mastopexy: Does It Improve Upper Pole Fullness and Breast Harmony?

Abstract

Utilization of autologous parenchymal flaps aims to attain enduringly favourable outcomes and uphold volume in the upper breast pole after mastopexy procedures. The objective of this study was to juxtapose and scrutinize postoperative upper pole fullness, upper/lower pole ratios, occurrences of bottoming-out deformity, and complication rates between two patient cohorts: those who underwent the wise-pattern superior pedicle mastopexy with the LIFT technique and those who underwent the conventional wise-pattern superior pedicle mastopexy. All the patients in this study were appropriately categorized as primary patients, signifying their lack of any prior breast surgery history. These individuals presented with grades II and III breast ptosis on both breasts, ranging from moderate to severe deformities per the Regnault classification. Importantly, all patients uniformly expressed their desire to achieve a firmer breast appearance without recourse to using breast implants. The patients' ages and preoperative breast measurements were recorded for analysis. Measurements, including the distance from the NAC to the inframammary fold and from the sternal notch to the NAC, were systematically measured both before the surgery and at the 1-year postoperative mark. The upper and lower pole ratios, defined by Mallucci and Branford, were found to be 45.22% ± 2.20% and 54.88% ± 2.20%, respectively, within the LIFT group. In 13 instances, a lower pole distance exceeding 55% indicated a potential bottoming-out deformity (value lower than 45%/55% ratio or 0.818). Conversely, within the control group, the upper and lower pole ratios were determined as 43.22% ± 2.80% and 56.88% ± 2.80%, respectively. These findings demonstrated statistical significance. Notably, in 39 cases within the superior pedicle wise-pattern mastopexy group, a lower pole distance surpassing 55% (value lower than 45%/55% ratio or 0.818) suggested a leaning towards a bottoming-out deformity (p: 0.003). A postoperative period of at least 12 months was essential to discern the emergence of upper pole fullness and the potential development of bottoming-out deformities. Among the cases within the LIFT group, 93% exhibited successful attainment of upper pole fullness, while in the control group, this outcome was achieved in 82% of cases (p>0.05). Implementing the LIFT technique alongside the wise-pattern superior pedicle mastopexy decreases the occurrence of bottoming-out deformity after 1 year. Although there is no statistically significant difference, the LIFT flap technique has contributed to some extent to upper pole fullness.
