OBJECTIVE: The primary objective is to assess the validity of nasal-noise masking audiometry ( @entity68707 ) as a clinical diagnostic tool in our @entity1 population. STUDY DESIGN: Retrospective case review. SETTING: Tertiary ambulatory referral center. @entity1 : @entity1 with @entity5274 ( @entity5274 ) were identified from referrals to our @entity5274 clinic primarily with symptoms including autophony, aural fullness, and hearing their own breathing. The healthy subjects had no history of @entity2169 . INTERVENTION: @entity68707 was measured in 20 ears of 10 healthy subjects as well as in 42 ears of 21 @entity1 with suspected @entity5274 . MAIN OUTCOME MEASURE: @entity68707 mean auditory thresholds were measured at frequencies ranging from 250 to 8,000 Hz. RESULTS: When stratified as definitive or probable @entity5274 based on observed tympanic membrane movement with breathing, both Definitive and Probable @entity5274 groups had significantly higher @entity68707 mean auditory thresholds compared to Normal ears at 250 Hz (p = 0.001, p = 0.003), 1,000 Hz (p = 0.019, p = 0.001), and 6,000 Hz (p = 0.4, p = 0.001). When stratified based on symptoms on the day of testing, both Symptomatic Ears and Non-Symptomatic Ears had significantly higher mean auditory thresholds compared to Normal ears at 250 Hz (p = 0.001, p = 0.015) and at 1,000 Hz (p = 0.002, p = 0.004). CONCLUSION: Our results demonstrate a larger masking effect in @entity1 with @entity5274 compared to normal subjects in the low-frequency region. In clinical practice, the relatively small effect and the wide variability of results between @entity1 have made this test be of little value clinically in our @entity1 population.
