Evaluation of long-term breast shape in inferior versus superomedial pedicle reduction mammoplasty: a comparative study.

Background: Among breast reduction mammoplasty, the inferior pedicle-based (IFP) technique is considered the most performed by plastic surgeons. A growing interest for the supero-medial based pedicle (SMP) mammoplasty technique has been documented in literature and clinical practice. However, no real evidence exists on the superiority of one technique over another.

Methods: This study represents a retrospective multimodal analysis, using a prospectively maintained database, comparing wise pattern breast reduction techniques (IFP SMP) over a 24-month follow-up. From January 2015 to July 2017, all patients undergoing wise pattern bilateral reduction mammoplasty, using either an IFP or a SMP technique, were included in the study and divided in two groups. Pre-operative breast measurements included sternal notch-to-nipple distance (SN-N), infra-mammary fold to inferior border of Nipple Areolar Complex (NAC) distance length and ptosis. The same measurements were recorded at 2 weeks, 6 months and 24 months post-op. Complications were recorded and aesthetic outcomes were evaluated.

Results: A total of 58 patients were included in the study, among which 36 (62%) were treated with a SMP technique and 22 (38%) with an IFP technique. At the 24-month follow-up timepoint, the SN-N distance was significantly shorter (*P<0.05) in the SMP group, with a significantly smaller elongation of the lower pole arc (29.5% increase in length in the SMP group and 40.9% in the IFP group). Aesthetic result gave significantly higher mean VAS score for SMP patients compared to IFP patients.

Conclusions: The SMP technique provides stable and satisfactory results in term of breast shape, overcoming some of the major concerns related to the use of an IFP technique (lower pole elongation and ptosis recurrence), maintaining a superimposable complication rate.
