RESUMO
BACKGROUND: Silicone implants have gone through adaptations to improve esthetic outcomes. With the progress of technology, including gel rheology, different properties have been introduced. Ergonomic style implants (ESI) feature enhanced rheological properties and provide a shaped contour with a round base. OBJECTIVES: This study investigated outcomes for ESI in breast augmentation concerning lower pole stretching (LPS) and implant stability and describes an algorithm to assist in decision-making. METHODS: A total of 148 patients (296 breasts) underwent breast augmentation with ESI; this procedure was indicated in patients with good skin quality and <6 cm between the nipple-areola complex and the inframammary fold. RESULTS: The mean patient age was 29.6 years (range: 19-39), and 93 patients (62.8%) underwent primary breast augmentation with demi/full projection (average volume of 245 cc [175-375 cc]). Axillary incision and subfascial pocket were indicated in 115 (77.7%) and 72 (48%) cases, respectively. Average LPS values were 32.2% (24.91 mm) and 10.86% (9.42 mm) at up to 10 days and 10 days to 12 months postprocedure, respectively. Patients were followed for a mean of 29.9 ± 26.4 months (range: 6-66). Complication rates per breast and per patient were 5% and 10%, respectively, and included subcutaneous banding in the axilla (1.6%), implant displacement (1.2%), and wound dehiscence (0.8%). No cases of infection, seroma, or rippling complications were observed. CONCLUSIONS: The present decision-making algorithm summarizes the process involved in breast augmentation using ESI and is intended to help standardize decisions. With correct planning, long-lasting outcomes can be achieved due to favorable interactions between ESI and the patient's tissues.
