title: [Predictive value of intraoperative monitoring of brainstem acoustic evoked potentials during removal of parabrainstem tumors].
abstract: The data of intraoperative monitoring of brainstem acoustic evoked potentialities (BAEP) during parabrainstem tumors are analyzed. Of the 24 cases, 16 patients were found to have neurinoma of the acoustic nerve, 4 had petroclival meningioma, 2, tentorial meningioma, 1, cholesteatoma of the cerebellopontine angle, and 1, brainstem angioma. The authors proposed to identify the favorable and unfavorable patterns of BAEP as predictors of an early postoperative period, by comparing the patterns of BAEP, the data on the monitoring vital functions and outcomes of disease. The conformity of actual and predictable results was analyzed. By taking into account the high coincidence of actual and predictable outcomes (79.16%), it can be suggested that the data of intraoperative monitoring of BAEP are not only of value for obtaining information at the moment of surgery, but also informative as a predictor of an early postoperative period and outcomes of disease.
