Language test for speech mapping in neurosurgery

Speech mapping during craniotomy in the awake patient is the golden neurosurgical standard to detect critical brain regions and thus leave them intact during the tumor resection. Electrical stimulation temporarily disrupts the stimulated cortex region’s activity, which results in the immediate response - such as speech arrest or disruption. Thus, a unique anatomical map of speech region’s distribution is outlined. The neurosurgeon determines functional impact of these regions and maximally avoids their resection. This approach allows to efficiently minimize and stabilize the tumor while saving patient’s speech ability and preserving his quality of life. 

A fine speech test is a crucial part of the intraoperative speech mapping. Some of the most popular tasks for the automatic speech (count to 10, naming the days of the week, etc.) are not very effective. In collaboration with Burdenko Neurosurgery Institute and Pirogov National Medical and Surgical Center, Moscow, and Federal Neurosurgical Center, Novosibirsk, we developed the speech battery in the Russian language for good qualitative and quantitative speech assessment and mapping in temporal, parietal, and frontal cortex and in the white matter tracts. Selection of the subtest based on the tumor localization allows precise detecting of critical speech regions. From 2014, we have successfully employed the test on actions and objects naming during awake stages of the craniotomy.
