Human acellular dermal matrix versus Integra® for single-stage oncologic scalp reconstruction: A multicentre cohort...

Area of Science:

• Regenerative medicine
• Tissue engineering
• Oncologic surgery

Background:

• Scalp defect reconstruction post-oncologic resection presents challenges due to tissue limitations and periosteal involvement.
• Complex reconstructive procedures carry significant morbidity, especially in elderly or frail patients.
• Acellular dermal matrices (ADMs) provide a potential single-stage wound coverage alternative.

Purpose of the Study:

• To compare the efficacy and cost-effectiveness of a tissue bank-manufactured human ADM versus Integra® for single-stage scalp reconstruction.
• To evaluate graft integration, healing time, and postoperative complications associated with each ADM type.

Main Methods:

• A multicentre observational study involving 16 patients undergoing scalp reconstruction after nonmelanoma skin cancer excision.
• Six patients received cadaveric human ADM, and ten received Integra®.
• Primary outcome: time to complete epithelialization; secondary outcomes: graft integration, complications, operative time, and material cost.

Main Results:

• All grafts achieved successful integration without failure.
• Mean healing time was significantly shorter with ADM (1.8 months) compared to Integra® (3.5 months).
• Tissue bank-derived ADM was approximately 72% less expensive than Integra® (€500 vs. €1,759).

Conclusions:

• Tissue bank-manufactured human ADM facilitates single-stage scalp reconstruction with successful integration and faster healing.
• ADM offers a substantially lower material cost compared to Integra®.
• Findings are preliminary due to the small sample size and observational design, warranting further investigation.
