Abstract

This technical note introduces the application of a 3D-printed external cranial protection device for contralateral subdural effusion after decompressive craniectomy (CSEDC). By applying this device over the cranial defect, the authors observed significant effects in reducing CSEDC formation, alleviating midline shift, and promoting neurological recovery. This report details the design and manufacturing process and presents comparative computed tomography images of a representative patient to demonstrate its efficacy.
