tissue expander
Inflatable medical device placed under the skin to gradually stretch tissue for reconstruction purposes.
Full Definition
A tissue expander is a balloon-like implant that is placed beneath the skin and gradually inflated with saline solution over several weeks or months to stretch the overlying tissue. This technique is commonly used in breast reconstruction following mastectomy, creating sufficient tissue to accommodate a permanent implant. Tissue expanders may be temporary (requiring later removal and replacement) or permanent (convertible to final implants). The expansion process requires multiple clinic visits for saline injections through a port system.
Usage
Usage note: Specify whether expander is temporary or permanent/convertible type.
