Conductive Hearing Loss
(Keywords: hearing loss, pain, ear pressure, itchiness, drainage, puss, fungus, water logged, earwax, accident, ear infections, child’s hearing loss, negative pressure, allergies, sinusitis, female hearing loss, genetic hearing loss, eustachian tube, and trauma)
Audiological test required: otoscopic evaluation, tympanograms, audiogram with both air and bone conduction thresholds.
Description: Hearing loss as a result of interference anywhere between the outer ear canal and the footplate of the stapes (the entry point of sound to the inner ear or cochlea). Swollen or inflamed tissue, ear wax, debris or foreign objects can cause a conductive hearing loss in the ear canal or external auditory meatus (purple area in the picture). Congenital (from birth) malformations, stiffness of the middle ear bones (ossicles), disruption/misalignment/breakage of the middle ear bones (ossicles), fluid (mucosal or puss), or negative (in some rare cases positive ear pressure) middle ear pressure can cause conductive hearing loss in the middle ear (from the ear drum to the footplate of the stapes, the green area in the picture). This can be caused by eustachian tube dysfunction. The picture below shows the structures related to conductive hearing losses.
Treatment: More often than not, these types of hearing losses are treatable. They may require simple procedures, medication, or may require surgery to regain hearing. An audiologist and an otolaryngologist (ENT-ears, nose, and throat physician) work together to identify and treat these conditions.
