Frame-based versus frameless stereotactic brain biopsies: A systematic review and meta-analysis

BACKGROUND: Stereotactic brain biopsy techniques have been a focus of rapid technological innovation. The recent advent of frameless stereotaxy has invited the question of whether it can provide the same diagnostic yield as frame-based techniques, without increasing risk of harm to patients. The goal of this meta-analysis was to compare each of these techniques in terms of yield and safety. METHODS: We independently searched four databases for …
