[The long-term changes after the implantation of silicone breast prostheses]

In a prospective study 60 patients with unilateral or bilateral mammary implants underwent mammography and sonography. Location, form and structure of the implants were evaluated. Additionally capsular fibrosis and its influence on the imaging quality of parenchyma was scored. We found increasing implant deformities and increasing density of the implants with increasing postoperative interval. There was poor statistically significant correlation between the thickness of the periprosthetic capsular and the postoperative interval in prepectoral implants (r = 0.555, p < 0.01); in case of subpectoral implants there was no such correlation. In 88% of the cases imaging quality was scored as adequate by two independent observers, with additional views in all cases. We conclude that sufficient imaging quality for the assessment of parenchyma and of potential implants complications may be obtained by the combination of mammography and sonography.
