Fat injection to correct contour deformities of the reconstructed breast: a single surgeon experience

Abstract

Aim: Autologous fat grafting has gained acceptance as a technique to improve aesthetic outcomes in breast reconstruction. The purpose of this study was to share our clinical experience using autologous fat injection to correct contour deformities during breast reconstruction.

Methods: A single surgeon, prospectively maintained database of patients who underwent autologous fat injection during breast reconstruction from January 2008 to November 2013 at McGill University Health Center was reviewed. Patient characteristics, breast history, type of breast reconstruction, volume of fat injected, and complications were analyzed.

Results: One hundred and twenty-four patients benefted from autologous fat injection from January 2008 to November 2013, for a total of 187 treated breasts. The patients were on average 49.3 years old (± 8.9 years). Fat was harvested from the medial thighs (20.5%), fanks (39.1%), medial thighs and fanks (2.9%), trochanters (13.3%), medial knees (2.7%), and abdomen (21.9%). An average of 49.25 mL of fat was injected into each reconstructed breast. A total of 187 breasts in 124 patients were lipo-infltrated during the second stage of breast reconstruction. Thirteen breasts (in 12 separate patients) were injected several years after having undergone lumpectomy and radiotherapy. Of the 187 treated breasts, 118 were reconstructed with expanders to implants, 45 with deep inferior epigastric perforator faps, 9 with latissimus dorsi faps with implants, 4 with transverse rectus abdominis myocutaneous faps, and 13 had previously undergone lumpectomy and radiotherapy. Six complications were noted in the entire series, for a rate of 3.2%. All were in previously radiated breasts. Average follow-up time was 12 months (range: 2-36 months).

Conclusion: Fat injection continues to grow in popularity as an adjunct to breast reconstruction. Our experience demonstrates a low complication rate as compared to most surgical interventions of the breast and further supports its safety in breast reconstruction. However, caution should be used when treating previously radiated breasts.
