| Summary: | Background:. Breast augmentation with anatomic implants can achieve a natural look, but over time, implant-related complications can occur. This includes a risk of potential rotation, which can cause a change in breast shape. Reported rates of rotation vary widely (0%–42%). Implant rotation is often detected by physical examination only or as a perioperative finding. Change in breast shape after augmentation requires clinical evaluation. In-office ultrasound allows for detailed assessment of implants for rotation and other complications.
Methods:. Women with anatomical breast implants seeking follow-up at the International Breast Implant Check Clinic in Stockholm, Sweden, from April 2020 to July 2022 were included in the study. Using a standardized protocol, subjective symptoms were recorded, and a physical examination followed by an ultrasound assessment was performed by a single board-certified plastic surgeon (M.J.) trained in implant assessment via ultrasound. Rotation was defined as an implant rotated past 30 degrees off the breast midline at 6 o’clock.
Results:. The study included 308 women (mean age 40.1, range 20-78) with bilateral anatomical implants. Overall, 40 women (13.0%) reported a change in breast shape; 35 had one or more implant-related complications, including five with rotation on ultrasound. Of the 308 women, 11 (3.6%) had rotations upon physical examination, and an additional 10 cases were identified using ultrasound.
Conclusions:. Rotation is a potential complication of anatomical breast implants. However, in this study, change in breast shape was more commonly caused by other implant-related complications. Ultrasound is a valuable tool in evaluating causes of change in breast shape.
