Purpose: The aim of this study was to evaluate the usefulness of intraoperative ultrasonography in combination with a navigation system.Methods: Between June 2012 and December 2012, 16 patients with intra-axial brain tumors underwent surgery using SonoSite ultrasonography, a StealthStation navigation system, and a SonoNav system. The ultrasonographic image was directly integrated into the navigation system, and the findings were compared with the preoperative images.Results: Intraoperative ultrasonography-linked navigation provided information about brain shift and the extent of resection during surgery. Using this type of assistance, total resection was achieved in 10 of 16 cases, and subtotal resection was achieved in 6. No operative complications were observed.Conclusions: Intraoperative ultrasonography supported by a navigation system improves the quality assurance of image-guided neurosurgery.
