What does SNHL mean on a hearing test?
What does SNHL mean on a hearing test?
Sensorineural hearing loss, or SNHL, happens after inner ear damage. Problems with the nerve pathways from your inner ear to your brain can also cause SNHL. Soft sounds may be hard to hear. Even louder sounds may be unclear or may sound muffled. This is the most common type of permanent hearing loss.
What is CHL hearing loss?
What is Conductive Hearing Loss (CHL)? Conductive hearing loss is caused by any condition or disease that blocks or impedes the conveyance of sound through the outer or middle ear. The result is a reduction in the sound intensity (loudness) that reaches the cochlea.
How is SNHL diagnosed?
Doctors use several types of tests to properly diagnose sensorineural hearing loss.
- Physical exam. A physical exam can help differentiate SNHL from conductive hearing loss.
- Tuning forks. A doctor may use a tuning fork test as an initial screening.
- Audiogram.
What is CHL in audiology?
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 (ossicles). If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.
Can SNHL be cured?
No cure yet Specifically, sensorineural hearing loss is caused by damage to hair cells of the inner ear and/or the auditory nerve that connects the ear to the brain.
What is sensorineural vs conductive hearing loss?
Conductive hearing loss occurs when sound conduction is impeded through the external ear, the middle ear, or both. Sensorineural hearing loss occurs when there is a problem within the cochlea or the neural pathway to the auditory cortex. Mixed hearing loss is concomitant conductive and sensorineural loss.
How can you distinguish between sensorineural and conductive hearing loss?
If the hearing loss is conductive, the sound will be heard best in the affected ear. If the loss is sensorineural, the sound will be heard best in the normal ear. The sound remains midline in patients with normal hearing. The Rinne test compares air conduction with bone conduction.
What is the most common cause of sensorineural hearing loss?
Rothholtz says that the most common cause of sensorineural hearing loss in adults is aging. This form of hearing loss occurs in the inner ear when tiny hair cells become damaged. The cells do not regrow, so the damage is permanent.
What is medical term CHL?
Classical Hodgkin Lymphoma (CHL)
