acellular dermal matrix
Also written as: ADM — Acellular Dermal Matrix
Processed human or animal dermis with cells removed, used as biological scaffold in reconstruction.
Full Definition
Acellular dermal matrix (ADM) is a bioengineered material derived from human or animal dermis that has been processed to remove cellular components while preserving the extracellular matrix structure. In reconstructive surgery, ADM serves as a biological scaffold that promotes tissue integration and provides structural support. Common applications include breast reconstruction, abdominal wall repair, and soft tissue augmentation. The material reduces complications and improves aesthetic outcomes by providing immediate lower pole support and tissue coverage.
Usage
Usage note: May be abbreviated as ADM after first use; specify source (human/porcine/bovine) when relevant.
In Context
- "Acellular dermal matrix was used to provide inferior pole coverage during tissue expander placement." — Operative technique description
- "The ADM demonstrated excellent integration with minimal inflammatory response at follow-up." — Post-operative assessment
