Outcomes evaluation following bilateral breast reconstruction using latissimus dorsi myocutaneous flaps

The demand for bilateral breast reconstruction has recently increased. Although numerous options exist, the latissimus dorsi myocutaneous flap remains a popular technique. The benefits of additional autologous coverage are evident; however, donor site morbidity does exist. The purpose of this report is to evaluate our experience with bilateral latissimus dorsi breast reconstructions, focusing on donor site morbidity and patient satisfaction. All patients who underwent bilateral latissimus dorsi breast reconstruction at Emory University Hospital, were evaluated and included in the series. Data points queried included patient demographics, risk factors, radiation therapy, timing of the procedure (immediate or delayed), type of procedure (latissimus dorsi only, latissimus dorsi with expander, latissimus dorsi with implant), and outcomes. Outcomes included >1 additional operation, any breast and any donor-site complications. A patient satisfaction survey was performed evaluating outcomes such as aesthetic results, general satisfaction, morbidities, and functional assessment. Comparisons were made using radiation therapy, timing of reconstruction, and type of reconstruction as variables. Eighty-three patients underwent bilateral latissimus dorsi breast reconstruction with an average follow-up of 2.3 years. The method of reconstruction included latissimus dorsi with expander (n = 54), latissimus dorsi only (n = 17), and latissimus dorsi with implant (n = 12). Breast complications occurred in 34% of the patients with radiation therapy being a significant risk factor. The average number of secondary operations was 2.3 with the expander group resulting in an increased need for additional procedures. Overall patient satisfaction was 3.93/5, with the average symmetry score being 3.82/5, shape 3.84/5, nipple position 3.92/5, and inframammary fold (IMF) position 4/5. The majority of patients (n = 28/37) reported no pain (0/5) at the time of the survey. Most patients (n = 33/37) reported no impairment in daily activities, however, some did report impairment in physical activity, decreased range of motion (ROM), and pain. The latissimus dorsi remains a reliable option for bilateral breast reconstruction. Although patient satisfaction with this approach remains high, functional impairment can occur and needs to be appropriately discussed.
