Asymmetric hearing loss: audiometric screening criteria.

摘要

To the Editor: Saliba et al. (1) addressed an important issue: in cases of asymmetric hearing loss, what is the best audiometric criterion for referral for magnetic resonance imaging (MRI) to rule out acoustic tumor? This question is usually couched in sensitivity and specificity, with MRI as the reference standard. If one criterion (e.g., asymmetry of >=15 dB at 3 kHz) has both better sensitivity and better specificity than another, it is considered preferable.
