Reconstruction of Full-Thickness Scalp Defects Using a Dermal Regeneration Template

Area of Science:

• Plastic Surgery
• Dermatology
• Oncology

Background:

• Large full-thickness scalp defects present significant reconstructive challenges.
• Traditional reconstruction often necessitates microvascular free flap procedures, which carry substantial risks.

Purpose of the Study:

• To introduce and evaluate a novel, less invasive reconstructive technique for full-thickness scalp defects.
• To demonstrate the efficacy of this method as an alternative to free flap reconstruction, performable without general anesthesia.

Main Methods:

• A retrospective review of 10 patients undergoing scalp defect reconstruction.
• The technique involved applying Integra bilayer wound matrix followed by delayed split-thickness skin grafting.
• Data collected included skin graft take, wound closure, and postoperative complications over a mean follow-up of 481 days.

Main Results:

• Excellent outcomes were observed in all 10 patients, with 90% achieving 100% initial skin graft take.
• Adequate wound bed coverage and acceptable cosmetic results were achieved.
• One patient experienced radiotherapy-induced wound breakdown, which resolved with conservative management.

Conclusions:

• This novel reconstructive technique for large full-thickness scalp defects offers a low-morbidity, outpatient-friendly option.
• It serves as a viable alternative to microvascular free tissue transfer, performed under local anesthesia and sedation.
• The procedure demonstrates excellent results with minimal wound care requirements.
