A novel approach in breast reconstruction: The extended lateral thoracic flip-over flap combined with loops and lipofilling (ELT FOLL).

[INTRODUCTION] The use of the thoracodorsal musculocutaneous flap has been limited to donor site complications, whereas the thoracodorsal fasciocutaneous flap spares the muscle and limits morbidities. Our objective is to describe a new technique of breast reconstruction using an extended lateral thoracic (ELT) flip-over flap combined with loops and lipofilling (ELT FOLL) to achieve better breast remodeling.

[METHODS] Between 2013 and 2018, 64 patients underwent breast reconstruction using an ELT FOLL. The flap is designed in an elliptical transverse pattern and extends 2 cm lateral to the back midline up to the breast axis at the level of the inframammary fold. The surgical technique consists of an infiltration and tunnelization of the breast recipient site and surrounding area, deepithelialization of the skin paddle, and additional preparation of the flaps and loops. Liposuction is performed using the power-assisted liposuction and lipofilling technique, and lipofilling is achieved throughout the thoracic cutaneous surface of the reconstructed site, particularly into the lower quadrant of the breast.

[RESULTS] Among the reconstructions, 73.4% was delayed and 92.2% was unilateral. A fourth of the patients were smokers, and 39.1% received radiotherapy. The total complication rate was 8.7%, the patient's shoulder function was not affected at long term, with the DASH score rising from 6.53 preoperatively to 11.32 at 6 weeks and 7.52 at 6 months. The average operative time was 57 min, and drains were removed at day one after surgery.

[CONCLUSION] The ELT FOLL should be considered a simple, safe, and reliable alternative for breast reconstruction.
