Objective: Stereotactic biopsy is a standard procedure in neurosurgery. While frame-based stereotaxis is considered the gold standard, some centers also utilize frameless imaging-based techniques and more recently robot systems. Here we report a retrospective analysis of our experience with 60 consecutive biopsies performed in our institution using the Neuromate Robot.

Methods: Between March 2013 and August 2016, 60 robot-assisted frameless biopsies were performed in 59 consecutive patients (age: 20-86 yrs., average: 63 yrs., male: 33) with 18 deep (insula, basal ganglia, thalamus, midbrain), 7 bilateral or callosal and 34 lesions deemed unresectable due to an otherwise eloquent localization. We retrospectively analyzed the histopathological results as well as complications and the duration of the procedures.

Results: A definite histological diagnosis could be established in 54 patients (92%) including 25 glioblastomas, 8 PCNSL, 3 metastases, 15 other tumors and 3 inflammatory processes. There were no infectious complications. Six patients (10%) suffered from an early surgery-related neurological worsening, which persisted in 2 cases (3%). Intracerebral haemorrhages requiring operative treatment was observed in 2 patients (3%). The average operating time was 45±17 minutes.

Conclusion: Frameless stereotactic biopsies using the Neuromate Robot are an alternative to frame-based stereotaxis with a similar diagnostic yield and comparable complication rates.
