Abstract
BACKGROUND: Standard electrostimulation cortical mapping includes application of electrical current to the explored areas through an electrode and marking of functional zones by means of paper tags with different symbols. This approach has several disadvantages. First, the electrode is moved randomly. It leads to overlooking of some zones, which causes mapping deficiency, and re-stimulation of others, which can trigger epileptic seizures. Second, the tags easily shift and close the marked structures. We describe a new simple device, that provides precise cortical mapping without indicated problems, and technique of its application.
METHODS: The device is a flexible polymer mesh with square pores of a certain size. Neurosurgeon applies the mesh onto the brain cortex and sequentially stimulates it through the pores. The functional areas are labeled. Pores corresponding to the lesion are cut out and the lesion is removed through the cutout without removing the mesh. After operation, the mesh is removed.
RESULTS: Using this technique, we operated a patient with glioma located near the primary motor cortex. The accessible cortical area was accurately mapped, and the tumor was resected without any complications. The mesh allowed us to significantly streamline the mapping process.
CONCLUSIONS: Our case illustrates that the proposed invention can be successfully used in neurosurgical operations for precise electrostimulation mapping of the brain cortex.
