What is the typical tympanogram result for conductive hearing loss?

The typical tympanogram result for conductive hearing loss is flat or abnormal. Conductive hearing loss occurs when sound waves are unable to efficiently pass through the outer ear, ear canal, or middle ear structures. This can be due to obstructions, fluid, or other conditions affecting the mechanisms that conduct sound.

A tympanogram is a diagnostic tool used to assess the functioning of the middle ear by evaluating how the eardrum responds to changes in air pressure. In the case of conductive hearing loss, the tympanogram may show a flat or abnormal tracing rather than the typical patterns seen in normal hearing. This flat appearance indicates poor mobility of the eardrum, which aligns with the idea of reduced sound transmission.

Normal tympanogram results usually indicate healthy middle ear function, while highly peaked results suggest a condition known as hypercompliance, often related to different types of ear problems rather than conductive loss. Extravagantly compliant tympanograms are also not typically associated with conductive hearing loss, as they signify a different issue with eardrum movement.
