Tissue Expanders
Tissue Expanders
Tissue expanders are medical devices used in reconstructive surgery to gradually stretch and grow new skin. This technique allows surgeons to generate extra skin that closely matches the color, texture, and quality of the surrounding area, making it ideal for natural-looking reconstruction.
Purpose
- Create additional skin for reconstruction
- Repair defects caused by trauma, burns, or surgery
- Support procedures like breast reconstruction or scar revision
- Improve aesthetic and functional outcomes
How Tissue Expanders Work
A soft, balloon-like device is placed under the skin near the treatment area. Over time, it is gradually filled with saline solution, causing the skin above it to stretch and grow. Once sufficient skin is created, the expander is removed and replaced with permanent reconstruction.
Common Uses
- Breast reconstruction after mastectomy
- Burn and scar reconstruction
- Correction of congenital deformities
- Scalp and facial reconstruction
Procedure Overview
- Placement Surgery: The expander is inserted under the skin
- Expansion Phase: Gradual filling over weeks or months
- Final Surgery: Removal of expander and reconstruction using newly formed skin
Duration of Treatment
- Initial surgery: 1 – 2 hours
- Expansion process: several weeks to months
Anesthesia
- General or local anesthesia (depending on procedure)
Recovery Time
- Initial recovery: 1 – 2 weeks
- Full treatment duration depends on expansion timeline
Benefits
- Uses patient’s own skin for natural results
- Better color and texture match
- Minimizes need for skin grafts
- Long-lasting and effective reconstruction
Important Considerations
- Requires multiple visits for expansion
- Temporary swelling or discomfort may occur
- Careful monitoring is essential
- Final results depend on individual healing
