Neuronavigation for Intracranial Meningiomas

According to its location, the surgical treatment of intracranial meningioma can be of considerable challenge for the neurosurgeon. Image-guided surgery essencially provides intraoperative localization for dynamic navigation and, also, improves the surgical planning. The continuous development of neuroimaging and computated technology promotes continuous improvement of navigation techniques and applications. In the last ten years, frameless image-guided surgery, also popularized as neuronavigation, is considered standard of practice by most neurosurgical centers around the world. Its usage can range from a simple craniotomy flap localization to a deep brain tumor resection respecting tract fibers, eloquent areas and neurovascular structures. In some cases, neuronavigation may not be necessary, but, if avaliable, it should promotes a safer surgery, as it has yet to become an integral part of intracranial procedures.
