Abstract
The superomedial pedicle reduction mammoplasty has gained popularity and is an important alternative approach for reduction mammoplasty, while the inferior pedicle reduction mammaplasty remains by far the most performed as it is considered to provide the best vascularization to the nipple-areola complex, allowing safe removal of large amount of redundant tissue. The authors conducted the first systematic review and meta-analysis in an attempt to declare the differences of the superomedial pedicle versus the inferior pedicle reduction technique by comparing the postoperative complications. PubMed, MEDLINE, and Cochrane Library for clinical studies were queried from inception to January 1, 2024. Review Manager Version 5.4 was used for this meta-analysis. A random effects model was applied to OR, and 95%CI were determined using the Mantel-Haenszel method. The I2 test was used to assess heterogeneity, and the Newcastle-Ottawa scale was used to assess the risk of bias in the nonrandomized studies. Twelve observational comparative studies were included. The superomedial pedicle technique had a statistically lower rate of overall complications (OR 0.59, 95% CI 0.47-0.75; p < 0.0001) and delayed wound healing (OR 0.46, 95% CI 0.33-0.64; p < 0.00001) than the inferior pedicle technique. No significant differences in wound dehiscence, infection, seroma, hematoma, skin necrosis, fat necrosis, NAC necrosis, nipple sensation decrease or loss, asymmetry, hypertrophic scarring, and reoperation were noted. Both two techniques are equally safe and reliable, while the superomedial pedicle technique resulted in a statistically lower rate of overall complications and delayed wound healing.
