tissue expansion
Process of gradually stretching skin and soft tissue to create additional coverage for reconstruction.
Full Definition
Tissue expansion is a reconstructive technique that involves placing an inflatable device beneath the skin and gradually filling it with saline over weeks to months. This process stimulates new skin growth and creates excess tissue for coverage of nearby defects. The technique is commonly used in breast reconstruction, scalp reconstruction, and treatment of burn contractures. Advantages include providing tissue with similar color, texture, and hair-bearing properties as the defect area. Complications may include expander exposure, infection, and patient discomfort during the expansion process.
Usage
Usage note: Distinguish between the process (tissue expansion) and the device (tissue expander) in documentation.
