Multimodal image-guided surgical robot versus 3D-printed template for brachytherapy of malignant tumours in the skull base and deep facial region: a clinical comparative study.

This study compared a multimodal image-guided robot and three-dimensionally (3D) printed templates for implanting iodine-125 (I) radioactive seeds in patients with malignant tumours in the skull base and deep facial region. Seventeen patients who underwent I radioactive seed implantation between December 2018 and December 2019 were included. The operation time, intraoperative blood loss, and accuracy of seed implantation were compared between the multimodal image-guided robot-assisted implantation (experimental) group (n = 7) and 3D-printed template-assisted implantation (control) group (n = 10).
