Abstract

fetched live from OpenAlex

BACKGROUND: This article examines outcomes following breast re-reduction surgery using a random pattern blood supply to the nipple and vertical scar reduction. METHODS: A retrospective review was conducted of patients who underwent bilateral breast re-reduction surgery performed by a single surgeon over a 12-year period. Patient demographics, surgical technique, and outcomes were analyzed. RESULTS: Ninety patients underwent breast re-reduction surgery. The average interval between primary and secondary surgery was 14 years (range, 0 to 42 years). The majority of patients had previously undergone primary breast reduction using an inferior pedicle [n = 37 (41 percent)]. Breast re-reduction surgery was most commonly performed using a random pattern blood supply, rather than recreating the primary pedicle [n = 77 (86 percent)]. The nipple-areola complex was repositioned in 60 percent of patients (n = 54). The mean volume of tissue resected was 250 g (range, 22 to 758 g) from the right breast and 244 g (range, 15 to 705 g) from the left breast. Liposuction was also used adjunctively in all cases (average, 455 cc; range, 50 to 1750 cc). Two patients experienced unilateral minor partial necrosis of the areolar edge but not of the nipple itself (2 percent). CONCLUSIONS: Breast re-reduction can be performed safely and predictably, even when the previous technique is not known. Four key principles were developed: (1) the nipple-areola complex can be elevated by deepithelialization rather than recreating or developing a new pedicle; (2) breast tissue is removed where it is in excess, usually inferiorly and laterally; (3) the resection is complemented with liposuction to elevate the bottomed-out inframammary fold; and (4) skin should not be excised horizontally below the inframammary fold. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
