Breastfeeding Ability After Breast Reductions: What does the Literature Tell us in 2023?

INTRODUCTION: Reduction mammaplasties are routinely performed on women of child-bearing age, yet there still exists some uncertainty regarding a patient's ability to breastfeed following the procedure. This is due to inconsistent definitions of "successful" breastfeeding, a variety of pedicles implemented, and inadequate follow-up in the published literature. Our aim was to summarize the current data and provide clear recommendations for counseling patients on expected breastfeeding outcomes following reduction mammaplasty. METHODS: A systematic review and meta-analysis in accordance with the PRISMA guidelines was conducted. We included papers that reported proportion of breastfeeding ability following reduction mammaplasty. RESULTS: We identified 33 papers that met our inclusion criteria. We found that women who undergo reduction mammaplasty are at a 3.5 times increased odds of not being able to breastfeed compared to controls. Overall, reduction mammaplasty patients have a breastfeeding success rate of 62%. The breastfeeding success rate for patients with inferior pedicles was 64%, superior pedicles was 59%, and lateral pedicles was 55%. No conclusions could be drawn regarding medial, central, vertical, and horizontal pedicles on breastfeeding ability. CONCLUSION: Current data suggest that women undergoing reduction mammaplasty have an increased odds of unsuccessful breastfeeding when compared to similar women who have not undergone the procedure. Based on the current literature, pedicle type does play a role in rate of breastfeeding success, although there is a need for further research on the aforementioned pedicles. Physicians should be aware of the likelihood of successful breastfeeding following reduction mammaplasty so that patients can be more thoroughly counseled prior to a decision for surgery.

Syringe Suction Yields Greater Adipocyte Viability for Fat Grafting: Fact or Fiction?

ABSTRACT: Autologous fat grafting is a technique that can be used for cosmetic and reconstructive indications such as oncologic defects, aging, trauma, and congenital malformations. However, there is no standardized technique, and one of the main challenges is the unpredictable rate of fat resorption. When using fat grafting, it is crucial to understand the different factors that contribute to adipocyte viability. A literature search, using PubMed, was conducted in 2022 with variations of the terms "autologous fat grafting," "fat harvesting," "fat processing," and "fat injection." Articles in the English language that presented original data about different factors that may affect adipocyte viability for fat grafting were included in this review. Syringe suction harvests (lower pressures), compared with other methods with higher pressures, were found to have increased adipocyte counts and viability, but this did not translate clinically during in vivo studies. The studies have shown that, despite our efforts in optimizing fat harvest, processing, and injection, no statistical or clinical differences have been found. Additional studies are still needed to determine a universal protocol for optimal fat graft survival.
