The modified serratus anterior fascia flap improves satisfaction and long-term results in immediate implant-based breast reconstruction: A retrospective study

Abstract

After immediate implant-based breast reconstruction (IIBR) following skin-sparing mastectomy, postoperative complications such as implant exposure or badly defined mammary folds can occur. Acellular dermal matrix can provide good esthetic outcomes but remain expensive. This study evaluates a new technique of one-stage IIBR by using a modified serratus anterior fascia flap (MSFF group), providing lower implant coverage, as compared to the classical submuscular technique. In this retrospective study, we included all patients who underwent IIBR using either the MSFF technique or the classic technique between November 2012 and February 2015. We collected data regarding demographics, perioperative factors, postoperative complications, patient satisfaction (Breast-Q score), and esthetic outcomes. One hundred twenty-three patients who underwent IIBR, of which 61 breasts (59 patients) using the MSFF and 67 breasts (64 patients) the classical technique, were included. The size of the implants used were significantly higher in the MSFF group (p = 0.036). There were no statistically significant differences between the two groups with regard to the immediate complications rate. After a mean follow-up of 43.9 months, we observed more capsular contractures in the classic group (p<0.001). In the classic group, patients required more revision surgeries (p = 0.008), more implant changes (p<0.001), and higher volume of additional lipofilling (p<0.001). According to the Breast Q scores, patients' satisfaction was better in the MSFF group regarding their breasts (p = 0.001) and the outcomes (p = 0.009). The MSFF is a simple, safe, effective, and inexpensive autologous technique for IIBR, which improves implant coverage with a vascularized flap and provides satisfying outcomes as compared to classic IIBR, with less complications.
