ABSTRACT

Various surgical approaches and pedicles have been described to ensure safe and satisfactory results in reduction mammaplasty. Although different breasts require different techniques, complications are common. This study aims to assess the incidence of complications following primary bilateral reduction mammaplasties across a diverse range of pedicle methods within one of the largest single-center cohorts to date, utilizing machine learning methodologies. A retrospective review of primary bilateral reduction mammaplasties at a single surgical center between January 2016 and March 2020 was performed. Patient medical records and surgical details were reviewed. Complications were compared among three different pedicles. Binary recursive partitioning (CART) machine learning was employed to identify risk factors. In total, 1021 patients (2142 breasts) met the inclusion criteria. The superomedial pedicle was the most frequently utilized (48.0%), with an overall complication rate of 21%. While pedicle-based subgroups demonstrated significant demographic variance, overall complication rates differed most between the inferior (24.9%) and the superomedial pedicle (17.7%). Statistical analysis identified resection weight as the sole significant independent risk factor (OR 1.001, p = 0.007). The machine learning model revealed that total resection weights exceeding 1700 g significantly increased the risk of overall complications, while a sternal notch to nipple (SNN)-distance > 36.5 cm correlated with complications involving the nipple-areola complex (NAC). Higher resection weights are associated with elevated complication rates. Preoperative assessment utilizing SNN-distance can aid in predicting NAC complications.

ABSTRACT

BACKGROUND: With the increasing demand for autologous breast reconstruction, different surgical techniques have emerged to provide patients with the best possible result tailored to their individual needs. The upper thigh provides an alternative tissue resource in patients where abdominal based flaps are not feasible. While surgical outcomes and donor-site morbidity demonstrate favorable results using abdominal as well as thigh based free flaps for autologous breast reconstruction, the differences in skin constitution and color between the two flap donor-sites have not been investigated. METHODS: From our flap data base, 60 patients who underwent unilateral secondary breast reconstruction with free DIEP or TMG flaps where randomly selected from our database. In both cohorts, postoperative pictures were used for photometric color evaluation of the reconstructed breast using the Delta E 2000 score at Time A (1.5 - 3 months), Time B (6 - 8 months) and Time C (12 - 20 months). Standard univariate descriptive statistics and group comparisons were performed. RESULTS: The DIEP flap demonstrated a better skin color match at Time A (p < 0.001), Time B (p = 0.003) and Time C (p = 0.009). Over time, both flaps showed improved Delta E 2000 values, and patient age was only associated with higher Delta E 2000 values in TMG flaps after 1.5 - 3 months (p = 0.021). CONCLUSION: The study provides the first objective analysis of skin color match in secondary autologous breast reconstruction. The DIEP flap reconstruction shows a preferable color match compared to the TMG flap. Both free flaps demonstrate an improved skin color match 12 - 20 months after secondary breast reconstruction.

ABSTRACT

BACKGROUND: The transverse myocutaneous gracilis (TMG) flap is a viable and safe option for breast reconstruction in patients with limited abdominal tissue or other contraindications for abdominal-based flaps. Although it is one of the most common flaps employed for breast reconstruction, data on patient-reported outcomes is limited. OBJECTIVES: The authors seek to evaluate patient satisfaction and aesthetic outcome after breast reconstruction with the TMG flap. METHODS: All patients who underwent breast reconstruction with a TMG flap between March 2010 and October 2020 were identified. Invitation to a digital version of the BREAST-Q reconstructive module and the Lower Extremity Function Scale (LEFS) was sent to 105 patients. Patient demographics, complications, and surgical details were collected and retrospectively analyzed. BREAST-Q and LEFS scores were calculated and compared to the literature. RESULTS: Eighty-two patients participated in the study. Median follow-up was 5.9 years, with a mean patient age of 45.7 years. Most patients (90.2%) received treatment due to previous cancer of the breast, and 17.1% underwent immediate reconstruction. The mean score for "Satisfaction with Breast" was 66/100. Postoperative lower extremity function was high, with a median LEFS score of 78/80. A LEFS score below the median value was found to be significantly associated with active smoking (P = .049). Patients also reported high satisfaction with donor sites (8/11). CONCLUSIONS: Patient satisfaction and aesthetic outcome after breast reconstruction with TMG flaps is high and comparable to other common techniques. Lower extremity function is not impaired after flap harvest.
