“…Approximately 50 years ago [ 24 ], an implant with a polyurethane (PU) foam coating was reported with the aim to prevent the risk of CC associated with silicone breast implants [ 25 ]. Thereafter, textured (TE) surfaces have been developed to mimic the shape and the benefits of the PU foam, and several studies have indicated that PU implants have a lower incidence of CC [ 17 , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] ]. Furthermore, two studies have suggested that PU implants are associated with a lower incidence of CC in case PMRT is delivered [ 32 , 35 ].…”

Background: Capsular contracture (CC) is the most common complication following Immediate Breast Reconstruction (IBR) with breast implants. Different implant surfaces were developed aiming to reduce the incidence of CC. We evaluated the incidence and degree of CC after Direct-to-Implant (DTI) IBR with insertion of textured (TE) or polyurethane (PU) covered implants. Methods: A retrospective review of consecutive patients treated at our Institution with mastectomy and one-stage IBR and implant reconstruction between 2013 and 2018, with or without post mastectomy radiation therapy (PMRT), was conducted. Immediate breast reconstruction was performed by implanting 186 PU covered implants and 172 TE implants. Results: Three-hundred-twelve women underwent 358 DTI IBR with PU or TE implants, were analyzed with a median follow-up time of 2.3 years (range 1.0e3.0). The overall rate of CC Baker grade III and IV was 11.8% (95%CI: 8.4e16.3), while, after PU and TE implant placement it was 8.1% (95% CI: 4.1e15.7) and 15.8% (95% CI: 4.1e15.7) [p ¼ 0.009]), respectively. Irradiated breasts developed CC more frequently rather than non-irradiated breasts (HR ¼ 12.5, p < 0.001), and the relative risk was higher in the TE group compared with the PU group (HR ¼ 0.3, p ¼ 0.003). Conclusions: After mastectomy and one-stage IBR, the use of PU covered implants is associated with a lower incidence of CC compared to TE implants. This advantage is amplified several folds for patients who necessitate PMRT.
