Summary: Sensory neural hearing loss is caused by damage to the inner ear or auditory nerve, which results in permanent hearing loss. Learn more about how conventional therapies assist in SNHL and why the new regenerative research is speculating if it might be feasible to repair the inner ear later on.

Why the sense of hearing is important? Having a sense of hearing is fundamental to the establishment of both communication systems, and balance systems for patients that keep everything in place. It also affects overall quality of life. However, if the inner ear or auditory nerve is damaged, the result often leads to sensorineural hearing loss – a condition that affects millions of patients around the world. Unlike the temporary hearing problems caused by earwax, otitis media, etc., of which one’s hearing will recover with time, this kind often involves permanent cellular injury.

However, patients, who underwent traditional treatment often get only symptoms based relief. Fortunately, with good research in regenerative medicine, scientists now focus on the treatment that provides relief by addressing the underlying cause.

What Is Sensorineural Hearing Loss?

Patients dealing with sensorineural hearing loss suffer through a type of hearing impairment that happens due to damage or dysfunction within the inner part of ear, especially the cochlea, or auditory nerve pathways. It is the most prevalent form of hearing impairment conditions that can progress towards more degree of severity.

Symptoms of Sensorineural Hearing Loss

Patients suffering from sensorineural hearing loss, often experience varieties of symptoms depending on the severity of the cause. These symptoms are often subtle and not easy to recognise, until it disturbs the daily life.

• Patients may hear deep voices better than high-pitched voices.
• It gets harder to hear in noisy environments.
• Patients can hear the voices of others as mumbling sounds.
• Ears often feel ringing.
• Maintaining balance often becomes difficult because the inner ear is affected.

Cause of Sensorineural Hearing Loss

Sensorineural hearing loss often happens when the inner part of the ear, especially the tiny hair cells in your cochlea, gets damaged or affected through trauma, illness, etc. Although, some patients are born with SNHL, which happens due to lack of oxygen or other complications during the fetal development.

How Is SNHL Diagnosed?

Diagnosis is generally accompanied by:

• Pure tone audiometry for determining hearing thresholds.
• Discrimination Tests for speech to evaluate how well sounds are understood.
• Magnetic Resonance Imaging (MRI) in the diagnosis of nerve deterioration suspected.
• Complete ear, nose, and throat examination.

Finding the problem early is related to good prognosis for long term hearing management.

How Traditional Treatment Manages Sensorineural Hearing Loss?

Traditional treatment that treat sensorineural hearing loss often includes the following treatments:

Hearing Aids: Patients are provided with a device that amplifies sound like tiny sounds and make them easier for the patient to hear.

Cochlear Implants: These surgically implemented devices in the patient ear, bypasses the patient’s inner ear and develops a new pathway for sound to reach the brain.

Medications: If the problem is caused by inflammation or illnesses, patients are provided with medications for soothing the symptoms.

Bone-Anchored Hearing Aids: This surgical implemented device uses the vibrations to send sound to the inner ear. This approach works better when patients only have one-sided sensorineural hearing loss.

Regenerative Options: Exploring the Future of Hearing Restoration

Patients tired of getting temporary relief often look for more advanced treatment. Fortunately, regenerative medicine is being studied for the potential of repairing the damaged inner ear structure.

Stem Cell Therapy Research: Stem cells are also being investigated for their ability to restore cochlear hair cells or sustain the auditory nerve.

Neuroprotective Approaches: Stem cells may secrete growth factors that help to protect the remaining auditory neurons.

Exosome-Based Therapy: Cell-derived vesicles are being researched as a possible means of enhancing tissue repair in the inner ear.

Gene Therapy Advances: Research is underway to identify genes related to hair cell regeneration.

It should be noted that the majority of the therapies in regeneration medicine are still in the investigation stage. The evidence for the therapies is for research purposes only.

The Future of Regenerative Hearing Research

In the field of regenerative medicine for SNHL, scientists around the world are continuing to make efforts to explore better strategies for hearing restoration. Combining other therapies involving stem cells, gene modulation and neuroprotective treatment are currently being examined in the early phase trials. Although, results seem optimistic, it is still in the initial stages.

To stay up-to-date or consider regenerative medicine as treatment, consulting with experts is important. Stem Cell Care India, provides the best knowledge from the experts in the field, reliable support during the treatment, and also connecting patients with the best healthcare.

Putting It All Together

Sensorineural hearing loss is a challenging condition for the patients. Traditional treatments often provide symptoms based relief. Fortunately, with advancement in the field of regenerative medicine, patients can now hope for better supportive treatment for better well-being.

Frequently Asked Questions

Q1. What is the primary reason for sensorineural hearing loss?

Ans. Sensorineural hearing loss primarily occurs due to damage to the inner ear hair cells or the auditory nerve, which could be due to aging, exposure to loud noises, infections, or the use of certain drugs.

Q2. Is sensorineural hearing loss a permanent condition?

Ans. Yes, in most instances. The fact is that the hair cells in the cochlea do not regenerate in human beings, and thus this type of hearing loss is generally irreversible.

Q3. What are the initial symptoms of sensorineural hearing loss?

Ans. The initial symptoms include the inability to comprehend speech, the sensation of muffled sounds, ringing in the ears (tinnitus), and the inability to hear high-pitched sounds.

Q4. Can stem cell treatment help restore hearing?

Ans. Stem cell treatment is still being tested on patients. Although it holds promise as a potential tool for regeneration, it is not yet a proven or guaranteed remedy for restoring hearing.

Q5. What is the current treatment for sensorineural hearing loss?

Ans. The current treatments for this condition include the use of hearing aids and cochlear implants, as well as steroid treatment in some cases.
