Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear . If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.
Low-frequency conductive hearing loss is present in many patients with SCDS and is explained by the dehiscence acting as a "third window." Vibrations entering the ear canal and middle ear are then abnormally diverted through the superior semicircular canal and up into the intracranial space where they become absorbed instead of being registered ...
Superior semicircular canal dehiscence, a gap in the bone cover above the inner ear, can lead to low-frequency conductive hearing loss, autophony, and vertigo. Syndromic hearing loss can be either conductive or sensorineural. It occurs with abnormalities in other parts of the body.
Vertigo. Fluctuating hearing loss. Tinnitus. Ear fullness. These symptoms tend to come and go over time and can vary from mild to severe. Some people with Ménière's disease only experience ...
Scientists know that ringing in the ears, or tinnitus, is associated with hearing loss, aging, head or neck injuries, and exposure to loud noises. But what’s actually happening in the body to ...
PTA can be used to differentiate between conductive hearing loss, sensorineural hearing loss and mixed hearing loss. A hearing loss can be described by its degree i.e. mild, moderate, severe or profound, or by its shape i.e. high frequency or sloping, low frequency or rising, notched, U-shaped or 'cookie-bite', peaked or flat.
Those with only conductive hearing loss are often treated medically or with surgery without imaging. The diagnosis may be unclear clinically in cases of sensorineural or mixed hearing loss and may become apparent only on imaging. Therefore, imaging is often performed when the hearing loss is sensorineural or mixed. [citation needed]
A perforated eardrum leads to conductive hearing loss, which is usually temporary. Other symptoms may include tinnitus, ear pain, vertigo, or a discharge of mucus. [1] Nausea and/or vomiting secondary to vertigo may occur. [2]
