Functional hearing loss may be associated with which condition?

• A. Outer ear cerumen impaction.
• B. Auditory neuropathy/dys-synchrony.
• C. Otitis externa.
• D. Presbycusis.

Answer: (B)

Functional hearing loss is a nonorganic or inconsistent finding—responses don’t line up with what the testing shows or with the presumed level of hearing. Auditory neuropathy/dys-synchrony fits with this pattern because the problem isn’t a simple loss of sensitivity in the outer or middle ear but a disruption in how neural signals are transmitted and synchronized along the auditory pathways. In ANSD, outer hair cells may work (sometimes OAEs are present) yet the timing of neural firing is off, which often leads to disproportionately poor speech understanding and results that don’t match the degree of hearing loss suggested by thresholds. That mismatch can resemble functional or nonorganic responses on behavioral tests, so ANSD is a plausible association when nonorganic findings are suspected. By contrast, cerumen impaction, otitis externa, and presbycusis are organic conditions that produce measurable changes in hearing and aren’t typically linked to nonorganic presentations.
