Clinical Use of Skull Tap Vestibular Evoked Myogenic Potentials for the Diagnoses of the Cerebellopontine Angle Tumor Patients
Figure 3
Preop (solid lines) and postop (dashed lines) VEMP waveforms recorded ipsilateral to the pathology from all 3 subjects. All the waveforms are normalized according to prestimulus EMG activity. Abbreviations are used in this figure as follows where ipsilateral indicates the location in return to the pathology location. AHLB: ipsilateral auditory head lift recording with both ears stimulated; AHL: ipsilateral auditory head lift recording in return to ipsilateral stimulation; FHLB: ipsilateral head lift recording tapper located at forehead; MHL: ipsilateral head lift recording tapper located at left mastoid recorded bilaterally; MHLR: head lift recording tapper located at ipsilateral mastoid.
