Management of Breast Deformity After Removal of Injectable Polyacrylamide Hydrogel: Retrospective Study of 200 Cases for 7 Years.

Abstract：

BACKGROUND:Polyacrylamide hydrogel (PAAG), once used as an injection for breast augmentation, has been banned in the medical field for cosmetic purposes for more than 10 years in China. But a large number of breasts have characteristic deformities due to the gel's feature of erosion. Our aim is to explore a retrospective study on PAAG's long-term effects on women, ensuing breast deformity and the strategy for breast plasticity after removing the gel in our center from 2007 to 2014. METHODS:From 2007 to 2014, 200 patients, whose breasts were injected with PAAG, underwent the operation to remove the injectable material. Complications were summarized. Ultrasound or MRI was performed before the operation to disclose the general distribution of the gel and the muscle and gland infiltration. According to the gel distribution, muscle and gland infiltration, infection, gel residue, and other factors, the patients were treated, respectively, with or without prosthesis implantation surgery after the removal of the gel. According to the decision about whether or when to undergo prosthesis implantation, the patients were classified into three types: group I-prosthesis implantation at the first stage, group II-prosthesis implantation at the second stage, and group III-only removing the material without prosthesis implantation. The scores of the BREAST-Q program were used to evaluate the preoperative and postoperative differences. RESULTS:Seventy-seven patients underwent prosthesis implantation at the first stage and 61 patients were operated on by placing the prosthesis at the second stage. A total of 62 patients only underwent the PAAG removal operation. By BREAST-Q evaluation, changes are summarized in Tables 1, 2, and 3 between mean preoperative scores and mean postoperative scores through categories of satisfaction with appearance of breasts, psychosocial wellbeing, sexual wellbeing, and physical wellbeing, in which all categories were presented with statistical significance (p < 0.001).

However, the surgery may destroy the shape of the breast. It is recommended that preoperative communication and local tissue condition are guidelines for surgeons to choose conservative or aggressive surgery. A balance must be maintained between removing the gel as much as possible and retaining soft tissue to reshape breasts.
