The Use of Water-assisted Liposuction for Breast Deformity Induced by Polyacrylamide Hydrogel.

Background: Approximately 200,000 women in China have undergone breast augmentation using polyacrylamide hydrogel (PAAG) injections. However, PAAG injections have been associated with complications such as mastalgia, gel migration, inflammation, infection, and nodular lesions. This study evaluated the effectiveness of the water-assisted liposuction (WAL) technique for PAAG and fibrotic capsule removal. Methods: This retrospective study included 7 patients with a history of PAAG breast augmentation. All patients underwent WAL-assisted PAAG aspiration and capsule removal. The procedure involved the use of high-pressure water jets to assist in the separation of the capsule from the surrounding tissues. Results: Seven patients were successfully treated with WAL-assisted PAAG aspiration and capsule removal. This technique enabled effective and rapid removal of both PAAG and the associated fibrotic capsule. No postoperative complications were observed during the follow-up period. All patients expressed satisfaction with the surgical outcomes. However, none of the patients underwent further cosmetic procedures after the operation. Conclusions: WAL provides a highly effective approach for PAAG removal by ensuring efficient gel aspiration, enabling controlled capsule dissection, and reducing surgical trauma. This technique minimizes complications and enhances postoperative recovery, making it a promising option for managing PAAG-related complications.
