BACKGROUND brainstem auditory evoked potentials in brain death. AIM to verify the agreement between the response in the auditory brainstem audiometry and the clinical outcome, analyzing the pattern of responses to electric stimulation. METHOD a cross-sectional study performed in 30 patients with Glasgow coma score of 3, submitted to the auditory brainstem audiometry and followed up until th...

Brainstem auditory evoked potentials (BAEP) were recorded during surgery as a monitor of brainstem function in three patients undergoing posterior fossa surgery for clipping of basilar aneurysms. In two patients, ligation of the basilar artery, and of a vertebral artery, was associated with deterioration in BAEP and resulted in postoperative brainstem dysfunction. In the third patient, postoper...

A functional relationship between brainstem and cortical auditory processing was shown to be abnormal in children with language-based learning problems (LP). Auditory evoked potentials were used to investigate brainstem and cortical responses to the speech sound /da/. The duration of the wave V-V(n) complex of the auditory brainstem response was studied, as was the effect of noise on correlatio...

Removal of a vestibular schwannoma may result in ipsilateral hearing loss and facial palsy. So intraoperative neurophysiological monitoring is an important method for detecting potentially preventing paralysis. Contralateral after removal rare complications. The detection acute contralateral has not been reported intraoperatively the pathomechanism unclear. Our case was 52-year-old female with ...

Hemifacial spasm (HFS) is an involuntary contraction of muscles on one side the face. It caused by compression facial nerve blood vessels. Microvascular decompression (MVD) effective treatment for HFS. However, complications such as hearing loss and dizziness may occur due to deficits during surgery. To prevent this, neural monitoring performed with brainstem auditory evoked potentials (BAEPs)....

Clinical features and evoked potential recordings were analysed in 32 patients with congenital atlantoaxial dislocation before and after surgery. Seven patients (group 1) had atlantoaxial dislocation, while 22 patients had associated basilar invagination (group 2). In both groups, pyramidal tract signs, posterior column signs, wasting of the upper limbs, and abnormality of somatosensory evoked ...
