Abstract

Objective
Burr hole trephination is a common treatment for chronic subdural hematoma, intracranial hematoma, and intraventricular hematoma due to its effective drainage of hematoma, minimal invasiveness and short operation time. However, cosmetic complications such as scalp depression can occur. The aim of this study was to evaluate the usefulness of an allogenic acellular dermal matrix (ADM) to prevent scalp depression at the burr hole site.
Methods
A retrospective analysis was performed with 75 cases in 66 patients who were treated with burr hole trephination from January 2018 to December 2019. These cases divided into 2 groups; based on the method used to cover the burr hole site: Gelfoam packing only (GPO) and ADM. The degree of the scalp depression was measured from the more recent follow-up brain computed tomography scan.
Results
There was a significant difference in the degree of scalp depression between GPO and ADM groups (p=0.003). No significant correlation between patient's age and the degree of scalp depression (GPO: p=0.419, ADM: p=0.790). There were no wound infection complication in either group.
Conclusion
ADM is a suitable material to prevent scalp depression after burr hole trephination.
