臨床聽力測試中假性氣骨導差的臨床盛行率與影響：1000耳研究

// Clinical Prevalence and Impact of False Air-Bone Gaps in Clinical Audiometry: A Study of 1,000 Ears

本研究分析1000耳感音神經性聽損（SNHL）案例中的假性氣-骨導差異（ABGs）現象｜發現假性ABGs最常出現在250 Hz及4000 Hz頻率，臨床上不以單獨250 Hz ABG做診斷｜建議臨床檢測可省略250 Hz骨導測試，聚焦500至4000 Hz頻率，提高診斷準確度與效率。

// This study examined false air-bone gaps (ABGs) in sensorineural hearing loss (SNHL) using audiometric data from 1,000 ears to assess diagnostic ambiguity and bone-conduction (BC) testing efficacy. False ABGs occurred most frequently at 250 Hz and 4000 Hz, with audiologists not relying on isolated 250-Hz ABGs for diagnosis. The findings suggest routine 250-Hz BC testing is unnecessary, and focusing on 500-4000 Hz frequencies improves diagnostic accuracy and efficiency.
