Speech, Impedance, and Auditory Brainstem Response Audiometry in Brainstem Tumors: Importance of a Multiple-Test Strategy

Audiometric Abnormalities in Children with Gaucher Disease Type 3

“…However, the ABR may indicate a brainstem abnormality, but there is no precise correspondence between the ABR waveform and anatomical lesion sites [16], while the interpretation of the ABR depends on peripheral hearing parameters, but audiometric thresholds in neuronopathic GD have not been reported. Audiologic detection and evaluation of brainstem disorders requires a multiple test strategy [17]. Acoustic reflex threshold measurement (ART) [6] and otoacoustic emission suppression by contralateral noise (MOCS) [30] are two objective tests, i.e., that do not rely on the patients response, that have been used for evaluation of brainstem lesions.…”

Auditory Brain Stem Responses and Nonsense Monosyllable Perception Test Findings for Patients with Auditory Nerve and Brain Stem Lesions

“…s -l o Stephens, et al, • reported that unilateral abnormalities in low redundancy speech tests, prolonged auditory reaction times, and reduced loudness growth on the al· ternate binaural loudness-balance test were related to ipsilateral wave IV abnormalities or contralateral wave V abnormalities of the ABR. Jerger, et al, 8 reported that the combination of normal or near ·normal pure tone sensitivity associated with an abnormal ABR is a strong retrocochlear sign. Musiek, et al, 10 reported that both ABR and central auditory test batteries were highly sensitive to brain stem lesions in this patient group as a whole, but the conventional speech discrimination test was not sensitive because none of the subjects with abnormal ABR demonstrated difficulty with speech discrimination.…”
