Site of lesion testing findings in a routine test battery

Audiologic test results in eight patients with confirmed retrocochlear lesions are cited and discussed with reference to reliability. Comparison as to diagnostic validity is made with older and more recent literature. Results suggest that standard test procedures of tone decay, threshold Bekesy audiometry, pure-tone configuration, and discrimination scores are the most consistent in routine audiologic examinations. Super Threshold Adoption Test (STAT), Stapedius Reflex Testing, Staggered Spondaic Word (SSW) testing, and PB Rollover were accurate in their test results. Other tests, including Alternate Binaural Loudness Balance (ABLB) and regular high level, Short Increment Sensitivity Index (SISI), were found to be less effective in routine site of lesion testing.
