Hyalomatrix coverage in scalp wounds with exposed cranium and dura

Abstract

Aim: The armamentarium of options available for soft tissue reconstruction of the scalp spans the reconstructive ladder. The purpose of this paper is to describe a case series of patients with exposed cranium and dura who were successfully reconstructed using esterified hyalomatrix (eHAM, Hyalomatrix, Medline Industries Inc., US). Methods: After obtaining Institutional Review Board approval, a retrospective review of the senior author's (ALF) patient database was completed. Patients who underwent scalp reconstruction using eHAM were identified. Each patient's chart was reviewed and data collected on demographics, days to skin graft, duration of follow-up, pathology, comorbidities and complications. Results: This case series consisted of five patients aged ≥18 years, with scalp wounds exposing dura or cranium, who were treated with eHAM as a bridge to definitive coverage with a skin graft. Each wound successfully granulated the exposed critical structure with the use of the eHAM. The mean time to skin graft coverage was 41 days, with a range of 13–79 days. Of the series of five patients, four had a follow-up of ≥12 weeks. The mean defect size was 90.2cm2. Conclusion: Complex scalp reconstruction can be accomplished using healing by secondary intention, skin grafts, local flaps, tissue expansion and free tissue transfer. As shown in this case series, another option available in select patients is using a dermal substitute such as eHAM. This is one treatment option available to reconstructive surgeons in multiple specialties.
