Objective: To investigate the complications in 16 patients who had breast augmentation with polyacrylamide hydrogel injection. The distribution and late changes of the injected material was observed.
Methods: The physical signs and symptoms of the 16 patients were classified. Ultrasound and infrared examinations or MRI were used in some cases.
Results: Two patients had operations for extraction. The injection material was distributed in the muscles diffusely, or existed in the breast and subcutaneous tissue as many masses.
Conclusion: The reliability of this injection method for breast augmentation is in doubt.
