The evidence base for the acellular dermal matrix AlloDerm: a systematic review

Area of Science:

• Regenerative Medicine
• Biomaterials Science
• Plastic Surgery

Background:

• Decellularized dermal matrices (DDMs) are widely used in various medical applications.
• AlloDerm is a prominent DDM with extensive literature.
• Understanding AlloDerm's clinical efficacy across different indications is crucial.

Purpose of the Study:

• To systematically review and summarize the clinical experience with AlloDerm.
• To stratify AlloDerm's applications by clinical indication.
• To assess the evidence base supporting AlloDerm's use.

Main Methods:

• Comprehensive literature search of Medline, EMBASE, and Cochrane Collaboration.
• Inclusion and exclusion criteria applied by two independent reviewers.
• Categorization of relevant articles by clinical application, study design, and evidence level.

Main Results:

• 311 articles were included, covering diverse applications like head and neck, breast, and trunk reconstruction.
• The majority of studies (over 85%) had an evidence level of 4 or 5.
• Positive outcomes were reported in 70% of articles, with neutral in 23% and negative in 7%.

Conclusions:

• AlloDerm demonstrates broad clinical utility with generally positive outcomes.
• Current evidence predominantly relies on descriptive and non-randomized studies.
• Future research should prioritize randomized controlled trials to strengthen evidence, particularly in high-impact areas.
