Sensorineural Hearing Loss

13 min read

Sensorineural hearing loss (SNHL) is a type of hearing loss that is caused by damage to the inner ear or the nerve pathways from the inner ear to the brain. It is the most common type of hearing loss, accounting for 90% of all cases. SNHL can be caused by a variety of factors, including aging, exposure to loud noises, certain medications, and head trauma.

Causes of Sensorineural Hearing Loss

The most common cause of SNHL is aging. As people age, the tiny hair cells in the inner ear that are responsible for converting sound waves into electrical signals can become damaged or die. This can lead to a gradual decline in hearing. Other causes of SNHL include exposure to loud noises, certain medications, and head trauma.

Diagnosis of Sensorineural Hearing Loss

SNHL is typically diagnosed through a hearing test. During the test, the patient will be asked to listen to a series of tones at different frequencies and volumes. The results of the test will be used to determine the type and degree of hearing loss. In some cases, additional tests may be needed to determine the cause of the hearing loss.

Prevention of Sensorineural Hearing Loss

The best way to prevent SNHL is to avoid exposure to loud noises. Wearing ear protection when exposed to loud noises can help reduce the risk of hearing loss. Additionally, avoiding certain medications that can cause hearing loss and avoiding head trauma can help reduce the risk of SNHL.

Symptoms

Signs and Symptoms of Sensorineural Hearing Loss

  • Difficulty hearing in noisy environments
  • Difficulty understanding speech
  • Ringing or buzzing sound in the ears (tinnitus)
  • Feeling of fullness in the ears
  • Difficulty hearing high-pitched sounds
  • Difficulty hearing in one or both ears
  • Muffled hearing
  • Dizziness or vertigo

Diagnosis of Sensorineural Hearing Loss

Sensorineural hearing loss is usually diagnosed through a hearing test. During the test, the doctor will measure the patient’s ability to hear different frequencies and volumes of sound. The doctor may also use imaging tests, such as an MRI or CT scan, to look for any damage to the inner ear or auditory nerve.

Treatment of Sensorineural Hearing Loss

Treatment for sensorineural hearing loss depends on the severity of the hearing loss and the underlying cause. Treatment options may include hearing aids, cochlear implants, or surgery. In some cases, medications may be prescribed to help reduce the symptoms of hearing loss.

Causes

Genetics

Genetics can play a role in SNHL. Some people are born with a genetic predisposition to hearing loss, which can be caused by a variety of genetic mutations. In some cases, the hearing loss can be inherited from a parent or grandparent.

Infections

Infections such as meningitis, measles, mumps, and rubella can cause SNHL. These infections can cause inflammation of the inner ear, which can lead to permanent damage to the nerve pathways.

Noise Exposure

Exposure to loud noises over a long period of time can cause SNHL. This is especially true for people who work in noisy environments, such as construction sites or factories. Even short-term exposure to loud noises, such as a concert or fireworks display, can cause temporary hearing loss.

Medications

Certain medications, such as certain antibiotics and chemotherapy drugs, can cause SNHL. In some cases, the hearing loss is temporary and will resolve once the medication is stopped. In other cases, the hearing loss can be permanent.

Aging

Aging is a common cause of SNHL. As we age, the nerve pathways in the inner ear can become damaged, leading to hearing loss. This type of hearing loss is known as age-related hearing loss or presbycusis.

Trauma

Trauma to the head or neck can cause SNHL. This can include physical trauma, such as a car accident, or a sudden change in pressure, such as when scuba diving or flying in an airplane.

Getting a Diagnosis

Steps for Diagnosis

The first step in diagnosing SNHL is to have a hearing test. This test will measure the ability to hear different frequencies and volumes of sound. If the results of the hearing test indicate a hearing loss, then further testing may be necessary. This may include an audiogram, which is a graph that shows the degree of hearing loss, and an auditory brainstem response (ABR) test, which measures the electrical activity of the auditory nerve.

In addition to these tests, a doctor may also order imaging tests such as an MRI or CT scan to look for any structural abnormalities in the inner ear or brain. Other tests, such as a vestibular evoked myogenic potential (VEMP) test, may also be used to assess the function of the inner ear.

Once the cause of the hearing loss has been determined, a treatment plan can be developed. Treatment may include hearing aids, cochlear implants, or other assistive devices. In some cases, surgery may be necessary to repair any structural abnormalities in the inner ear or auditory nerve.

Conclusion

Diagnosis of SNHL is important in order to determine the cause and develop a treatment plan. A hearing test is the first step in diagnosing SNHL, and further testing may be necessary. Imaging tests, such as an MRI or CT scan, may be used to look for any structural abnormalities in the inner ear or brain. Once the cause of the hearing loss has been determined, a treatment plan can be developed.
