Preferred Experience of Modifications to Emergency Surgical Treatment for Total Scalp Avulsion With Halo-Vest Head Ring and Quick Hair Removing.

Background: Total scalp avulsion is a fairly rear but severe soft tissue injury. Even with microsurgical replantation, the survival rate is still low. In this study, the authors incorporated 2 main modifications (Halo-Vest head ring and quick hair removing) and assessed the surgical outcomes versus those of traditional replantation.

Methods:: Eighteen patients were included in the study who suffered from total scalp avulsion. After consideration of the outcomes from the first 7 patients, the authors modified our surgical procedures and introduced the use of Halo-Vest head ring and quick hair removing in the treatments for the rest 11 patients. The surgical outcomes with both approaches were observed and compared, including the operation time and incidence of scalp necrosis.

Results:: The mean debridement time was 3.5 hours in traditional treatment versus 1.68 hours in modified treatment. The mean operative time was 11.14 hours in traditional treatment versus 8.05 hours in modified treatment. After the replantation, in those 7 patients without modifications, there was 1 total scalp necrosis and 6 partial scalp necrosis. In those 11 patients with modifications, there was 1 total scalp necrosis and 1 suffered a partial scalp necrosis, while the scalp survived well in other 9 patients. Classical cases with modified or traditional methods were reported respectively.

Conclusion: The application of Halo-Vest head ring and quick hair removing provides a reliable method to treat total scalp avulsion. It is safe, technically easy and worth being widely used in the clinical application.
