Appearances on ultrasound of impalpable injection port in a double chamber breast prosthesis

Abstract Breast reconstruction utilizing tissue expansion is being increasingly practised by both plastic and general surgeons. Our current experience for both immediate and delayed reconstruction is with the double chamber Becker prosthesis. The prosthesis with the resulting breast mound has on occasions rendered the injection port difficult to localize by palpation. We have found ultrasound useful in identifying impalpable ports and in facilitating needle insertion into the injection dome.
