Dorsal Lipomodeling to Treat Donor Site After Latissimus Dorsi Flap: Safety and Effectiveness

The latissimus dorsi flap (LDF) is a classic and efficient technique for breast reconstruction. However, its use has recently diminished in surgical practice due to dorsal disadvantages and to the increased use of microsurgical techniques for breast reconstruction, such as the deep inferior epigastric artery perforator flap.

The aim of this study was to evaluate the safety and efficacy of managing dorsal problems such as asymmetry, irregularities, and dysesthesia by lipomodeling the back region during the associated surgery for breast reconstruction.

A series of 300 patients operated by the last author for dorsal lipomodeling to correct sequelae after harvesting the total LDF, between November 2012 and March 2019, was analyzed.

The results show a very good improvement in the dorsal region in 6.7% of cases, good improvement in 86.7% cases, and fair improvement in 6.7% of cases. There was a good improvement in dorsal comfort in 90% of cases, a very good improvement in 6.66% of cases, and a fair improvement in 6.66% of cases. In 5% of cases 2 sessions were required to obtain a satisfactory result. No major complications were registered, and the only complication encountered were oil cysts in 2.6% of cases that were treated during consultation with percutaneous puncture.

This study showed that lipomodeling in the back area after LDF harvesting is an efficient and safe technique that corrects secondary dorsal sequelae such as irregularities, asymmetry, sensitivity, and dysesthesia. This technique should increase the indications for LDF because it decreases donor site sequelae, which are some of the main drawbacks of the LDF approach.
