Abstract

While frame-based stereotactic techniques have been the gold standard for highly precise, reliable, and accurate approaches to intracranial targets for decades, frameless stereotactic systems have evolved, with advantages including greater flexibility and patient comfort, and are widely used. Numerous studies have demonstrated comparable results regarding target accuracy and procedure-related complications in frameless stereotactic methods compared to frame-based systems. However, there are several technical concerns. This review examines frameless stereotactic brain biopsy techniques in the context of diagnostic yield and safety (i.e., procedural mortality or morbidity).
