Filter by:The breasts are paired, superficial organs with relative symmetry. They particularly characterize femininity as an erogenous area, in addition to playing an extremely important role in a woman's body aesthetics. Breast augmentation surgery aims to add volume or restore breast volume lost post-pregnancy or weight loss, often establishing a balance in the body silhouette and increasing self-esteem. Breast implants cause an inflammatory reaction with the consequent formation of a fibrous capsule around the implant, which can evolve with different degrees of contraction. Different factors are involved with the formation and intensity of the peri-prosthetic capsule: presence of hematoma, sub-clinical infection, silicone leakage, type of prosthetic envelope, plane/site of prosthesis placement, immune response, among others. The involvement of the envelope texture proved to be a major factor in reducing the formation of capsular contracture, which was clearly evident when covering with polyurethane foam was used. It is estimated that this reduction is due to the three-dimensional structure obtained with this configuration, which would result in a smaller vector resultant of contraction of the capsular fibers. Aiming to obtain less capsular contracture, a silicone prosthesis with a velvet/silicone foam envelope was developed, which theoretically would have the advantage of the velvet/foam structure similar to polyurethane without, however, presenting negative aspects such as degradation, inflammation and eventual toxicity of catabolites. In this way, it is expected to prove the best postoperative evolution regarding the use of silicone prostheses with velvet/silicone foam coverage, highlighting the maintenance of the breast position over time. Furthermore, to intend to verify whether the velvet/silicone foam coverage determines a lower incidence of capsular contracture compared to the textured envelope. To this end, evaluation will be carried out through clinical examination and evaluation of digital photographic images taken pre-operatively, 30, 120, and 360 days post-operatively. After a long postoperative period (approximately 9 years), a late follow-up will be carried out with the patients with clinical evaluation and a satisfaction questionnaire.
The study will evaluate the safety and performance of the ESTYME® MATRIX Round and Anatomical Silicone Gel-Filled Breast Implants in the breast augmentation and reconstruction.
This is a ten-year postapproval study to evaluate the long-term clinical performance of Sientra Silicone Gel Breast Implants under general conditions of use in the postmarket environment.
