Tissue expander

Tissue Expander

A tissue expander is a medical device used in reconstructive surgery and cosmetic surgery to facilitate the growth of new skin and other tissues. It is a temporary implant that is placed under the skin and gradually filled with saline over a period of weeks or months to stretch the skin and make room for a permanent implant or graft.

History

The concept of tissue expansion has been used in medical practice for centuries, but the modern tissue expander was first developed in the 1950s. The first commercially available tissue expander was introduced by the Mentor Corporation in the 1970s.

Uses

Tissue expanders are used in a variety of surgical procedures, including breast reconstruction after mastectomy, repair of burn scars, and correction of congenital anomalies. They can also be used in hair transplantation to increase the amount of available donor hair.

Procedure

The tissue expander is inserted under the skin near the area to be repaired. It is then gradually filled with saline through a valve, causing the skin to stretch and grow. Once the desired size is reached, the expander is removed and the new tissue is used to cover the defect or to create a pocket for a permanent implant.

Risks and Complications

As with any surgical procedure, there are risks associated with the use of tissue expanders. These can include infection, bleeding, and damage to surrounding tissues. The expander can also rupture or leak, requiring additional surgery to remove and replace it.
