Hearing loss is a condition in which a person loses the ability to hear anything at all. And this condition can be different from people to people. This condition started from mild, which can become severe if left untreated and can be ended up profoundly.

Mild hearing loss is that condition where the sufferer finds it difficult to keep up with soft conversations in noisy or loud environments/surroundings.

Severe hearing loss is kind of severe deafness in which a person is not able to hear loud speech without the usage of hearing aids.

Profound hearing loss is that condition where the sufferer is not being able to hear even with the usage of hearing aids.

Sudden hearing loss is an unexpected or quick loss of hearing suddenly. The reason behind sudden hearing loss varies from causes to causes.

Sudden sensorineural hearing loss is the same condition as sudden hearing loss which we are going to discuss in this article.


What is SSHL?

Sudden Sensorineural Hearing Loss (SSHL) is a quick loss of hearing either in one ear or both ears. SSHL can be happened due to the exposure to loud noises or there are many other cases.

It can be temporary or permanent. SSHL occur because of damage to the sensory organs of the inner ear.

It is an acute disorder. There is a loss of 30dB(decibels) in SSHL. The normal range of human hearing is 30 to 60 dB. If there is a loss of 30dB in SSHL the conversation sounds like a whisper to the patient.

SSHL is a disorder that requires proper treatment and medical care. More than half of the affected people with unilateral SSHL recovers within 1 or 2 weeks if they get the right treatment on time.

Sudden hearing gets worse if not get treated in time and even results in hearing loss. As it is an era of a technology the hearing aids and cochlear implants are able to help patients to improve their hearing problem.


Sudden Sensorineural Hearing Loss Causes

The main cause of SSHL is not specific. There is a number of causes for SSHL which include:

1. Acoustic Neuroma

Acoustic neuroma is also known as vestibulocochlear nerve, vestibular schwannomas or neurilemmoma. The acoustic neuroma helps in connecting the brain to the inner ear.

There are two different parts of acoustic neuroma. One part forwards the sound and the other one send balance information from the inner ear to the brain.

Symptoms of the acoustic neuroma are ringing in the ear called tinnitus, sudden loss of hearing and fullness of ear. Surgical treatment is the only way to get rid of it if the tumor is large.

2. Head Injury or Trauma

Head injury is a kind of injury to your brain skull or scalp. The severe head injury called trauma. Following are two types of head injury:

  • Closed head injury in which the skull of sufferer does not break.
  • Open head injury in which the skull of sufferer breaks and cause damage to the brain.

Symptoms of head injury might be nausea, headache, spinning sensation, vomiting and many more. The treatment done by the doctor will be on the basis of your head injury.

3. Menier’s Disease

Meniere’s disease occurs in the inner ear. It generally affects one ear. It causes pain and pressure in the ear due to excess of fluid. The other cause can be dizziness, vertigo, and tinnitus.

The symptoms can be hearing loss in the affected ear, headaches, nausea and many more. It can be treated by medicines, physical therapies, surgery and hearing aids.

4. Lyme Disease

Lyme diseases are the disease that is caused by the bacteria Borrelia burgdorferi. This bacteria can be transferred to humans by a bite of an infected black-legged or deer tick.

The tick got infected by eating infected deer or mice. To transfer the infection in the human body a tick has to present on the skin for 24 hours to 48 hours.

Symptoms occur in 3 stages. In the first stage, there is a rash on the infected area. After that in stage 2, there will be fever, sore throat, muscle aches, fatigue and many more.

Last but not the least 3rd stage, there will be severe headaches, difficulty in concentrating, arthritis and many more.

Early treatment is best and can be treated with antibiotics. Doxycycline for adults and children who are older than 8 years old. Cefuroxime and amoxicillin for adults, younger children, and women who are pregnant.

Other symptoms can also be seen like blood circulation problem, aging, trauma, Cogan syndrome, etc.

5. Congenital SSHL

These types of hearing loss are common in infants or babies:

  • Congenital Rubella Syndrome – It is the virus transferred to the baby during pregnancy. It can be controlled using the MMR or MMRV vaccine.
  • Cytomegalovirus – The most common cause of congenital sensorineural hearing loss in children. It is a viral infection that causes due to infected body fluids such as saliva or urine. As soon as the infants came into contact with fluids they are easily transmitted.
  • Toxoplasmic – It is a type of parasitic diseases. It can cause congenital sensorineural hearing loss to the fetus in the womb.

Sudden Sensorineural Hearing Loss Symptoms

Symptoms of the SSHL includes:

1. Dizziness

Dizziness is the feeling of being a weak and unbalanced body. The nerve that connects the inner ear to the brain if stops functioning cause dizziness. Most of the person feel dizziness like an annoyance in the inner ear.

2. Tinnitus

It is the term that is referred to the ringing, buzzing, whistling in the ears that cause damage to the inner ear. In this disorder, the sound produced from inside of your body, not from the external source.

There are different causes for tinnitus such as exposure to loud noise, earwax and many more and there are different therapies available to treat tinnitus.

3. Balance Problems

Balance problems are similar to dizziness. In balance problem, you feel like you are spinning while you are standing still. Symptoms of balance problems are blurred vision, nausea, vomiting, fatigue and many more.

It can cause inner ear problems, head injury, Blood pressure problems, arthritis, and many more things. It can be treated with medicine as well as with surgery.


Diagnosis of Sudden Sensorineural Hearing Loss

There are various ways to diagnose SSHL which include:

1. Otoscopy

In otoscopy, the external canal of the ear canal is examined. The instrument which is used in otoscopy is otoscope.

This device helps doctors to see directly into the ear canal. It uses the light to see clearly into the ear. It examines the external ear, middle ear, and eardrum.

2. Tympanometry

Tymponometry is a process of examining the condition of the middle ear and movement of the eardrum. It also checks the variations of air pressure in the external canal.

The test helps in recognizing the conductive hearing loss. The result of tympanometer is called a tympanogram.

3. Audiometry

Audiometry uses the Pure Tone Audiometry(PTA) hearing test. The test can distinguish between the conductive hearing loss, sensorineural hearing loss and mixed hearing loss.

PTA charts the hearing sensitivity for a standard frequency which lies between 250 and 8000Hz. PTA also charts for the high frequency which ranges from 8000 to 20000Hz. The result of audiometry is known as an audiogram.

4. MRI

MRI is abbreviated as Magnetic Resonance Imaging. It is used to plot the image of a body part in details. Basically, MRI is used for the congenital hearing loss.

It is used to diagnose the inner ear when there is an alteration in the shape of the inner ear or damage to hair cells. They are also used to recognize the tumor, damage to hearing loss due to bacterial infection.

Treatment of Sudden Sensorineural Hearing Loss

The sudden hearing loss is treated by the ENT specialist. To treat it in an effective way is to get treatment as soon as possible. Some common treatments include:

1. Circular Medication

In this procedure, the inner ear’s blood circulation is decreased. The required nutrients are supplied by the blood. If blood circulation is impaired than it damages the hair cells of the ear permanently.

The blood circulation of the inner ear can be treated with circular enhanced medication.

2. Local Anesthesia

Procaine and lidocaine are the two local anesthesia. If sudden deafness occurs than these two local anesthesia is used simultaneously to treat sudden deafness.

In this, administration blocks nerves that leads to vascular constriction. Treatment should be done by concerned doctors.

3. Hearing Aids

Sometimes sudden deafness causes permanent hearing loss. In this, there is permanent damage to the hair cells. Treatment of permanent hearing loss is hearing aids that help the individual to hear the noise around it.

4. Oxygen Pressure Chamber

Another name of the oxygen pressure chamber is Hyperbaric Oxygen Therapy. The treatment is done when suggested by the doctor. It is not an effective way to treat sudden deafness.

5. Dialysis

Dialysis is done for severe cases. It is used to clean the blood of a whole body and circulate it. Another name is heparin-induced extracorporeal LDL precipitation(H.E.L.P).
