Subcutaneous soft tissue expanders are used by plastic and reconstructive surgeons for a variety of skin defects. Gradual distension of the expander with saline allows progressive growth of the overlying skin. Access to the expander is via a subcutaneous port, which is easily palpable by the physician. Occasionally, due to overlying scar tissue or migration, the port is lost. In these cases, ultrasound is a useful method of rapid noninvasive localization of the lost tissue expander access port.

Key Words: tissue expander • access port • sonographic localization • reconstructive surgery
