Background: The extended latissimus dorsi (ELD) flap can provide adequate volume for breast reconstruction without an implant. The aim of this study was to identify a simple method to estimate preoperatively if the ELD flap would provide enough volume for breast reconstruction and good cosmetic outcome. The proposed model was based on correlating the preoperative body mass index (BMI) and breast cup size.

Methods: This retrospective cohort study included 64 patients who underwent immediate breast reconstruction with ELD at the National Cancer Institute, Cairo University, between January 2014 and January 2016. Preoperative breast cup size and patients' BMI were recorded. The primary end point was cosmetic outcome score assessed by three independent breast surgeons and the patients. Correlation analysis was performed between the preoperative factors and final cosmetic outcome.

Results: Sixty-four patients underwent immediate reconstruction following skin-sparing mastectomy. BMI range was 23–38 kg/m2 with a median of 28. All patients with cup size A had aesthetically pleasing results. As the breast cup size increased, the favorable cosmetic outcomes were noted with lower BMI. All patients with BMI higher than 33 had unfavorable results.

Conclusion: Favorable cosmetic outcomes are expected after ELD reconstruction in patients with cup size A regardless of the BMI. As the breast cup size increases, favorable cosmetic outcomes are expected in patients with lower BMI than in those with higher BMI. At a BMI of 34, no favorable cosmetic outcomes are expected. The prediction model will be validated in a prospective study.
