ObjectiveThree-dimensional (3D) printed models are used in the medical field. This study aimed to evaluate the feasibility and safety of a 3D-printed guide plate for use in brain biopsy.MethodsTwelve patients with intracranial lesions were retrospectively reviewed to determine clinical outcomes and technical procedural operability. These patients underwent brain biopsy assisted with the 3D-printed guide plate. Postoperative computed tomography was performed to assess the accuracy and associated complications of this guide plate.ResultsAll patients received definite diagnoses assisted by this guide plate. The deviations of the entry and target points were 3.93 ± 0.96 mm and 2.59 ± 0.11 mm, respectively. The angle drift of the puncture path was 5.12° ± 0.14°, and the deviation of the puncture depth was 2.35 ± 1.13 mm. The operation time ranged from 38.5 minutes with local anesthesia to 76.2 minutes with general anesthesia. No patient experienced complications.ConclusionsThe 3D-printed guide plate was noninvasive and had acceptable accuracy and the flexibility of frameless systems. The economic and operative benefits of this device supported its status as a powerful tool for brain biopsy in medical facilities in economically disadvantaged areas or institutions without navigation systems.Copyright © 2024 Elsevier Inc.
