Image-guided surgery for meningioma

Image-guided surgery (IGS-neuronavigation) has revolutionized the field of neurosurgery over the past few decades. Although commonly used for the diagnosis and resection of intracranial gliomas and metastases, IGS is also useful for meningioma surgery, particularly for accessing deep tumors, creating an optimal craniotomy for superficial lesions, and for showing the location of critical neurovascular structures deep to the tumor in skull base surgery. An additional bonus in meningioma surgery is that so-called brain shift is minimal or nonexistent, allowing for ongoing accurate navigation during the surgical procedure.
