Partial Latissimus Dorsi Muscle Flap With Implant for Immediate Breast Reconstruction

Latissimus dorsi flap is a widely used technique in breast reconstruction. Here we describe a modified method, the partial latissimus dorsi muscle flap with vertical incision for immediate implant-based breast reconstruction which has been used at our institution since 2014. Our primary objective is to determine the safety, prognostic benefit, and cosmetic outcome of this surgical procedure.

The study included a cohort of 31 breast cancer patients who underwent unilateral breast reconstruction with detailed follow-up information at Hubei Cancer Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2014 to March 2015. All procedures were performed by the same surgical team at the department of breast surgery. The data for selecting the appropriate implant and evaluating the surgical outcome were collected. The cosmetic outcome was evaluated by the BREAST-Q 1 y after surgery.

After a median follow-up of 69 mo, none of the patients showed local recurrence (although two patients had distant metastasis). The 5-y distant metastasis-free survival was 93.5%. The median duration of surgical procedure was 2 h and 24 min with few surgical and functional complications. Based on BREAST-Q, the outcome of Satisfaction with Breasts was "excellent" or "good" in 96.7% of the patients.

Partial latissimus dorsi muscle flap with the vertical incision is a safe, effective, time-saving, and feasible alternative to the whole latissimus dorsi flap which has superior cosmetic outcome and reduces recovery time. It is, therefore, worth advocating for application in clinical practice.
