BackgroundTraumatic brain injury (TBI) is a significant cause of morbidity and mortality across all age groups. Decompressive hemicraniectomy is the treatment for TBI-related refractory intracranial hypertension. The traditional technique for this procedure can result in wound complications due to injury of the scalp flap's vascular supply, namely the superficial temporal and postauricular arteries.MethodsIn this technical note we describe our experience using a novel technique that preserves both vascular territories by placing the inferior aspect of the incision posterior to the ear as opposed to anterior to it. This modification has the potential to reduce wound healing complications, especially in those at higher risk, while also reducing operative time by avoiding temporalis muscle incision and closure during procedure.ResultsAfter performing hospital chart review, a total of 7 patients were found who underwent this hemicraniectomy technique for severe TBI. Of these, 5 patients had this performed on the left side, and 2 patients had this performed on the right side. Six of the patients had an accompanying subdural hematoma, whereas 1 patient had no intracranial hemorrhage present.ConclusionsIn each case, both the superficial temporal and postauricular arteries were preserved, and rapid healing of the scalp flap occurred. In addition to providing a large bone window to allow the brain to swell, this technique has the potential to reduce complications of wound healing by preserving the vascular supply of the scalp flap and reduce operative times by minimizing temporalis muscle dissection.Copyright © 2020 Elsevier Inc.
