When Hearing Fades in an Instant: Understanding Sudden Sensorineural Hearing Loss
Sudden hearing loss, also known as Idiopathic sudden sensorineural hearing loss (ISSNHL), is a medical emergency that requires prompt attention. It is characterized by a rapid loss of hearing, often in one ear, over a period of minutes or hours This condition can be frightening and disrupt daily life, making it essential to seek immediate medical help.

What Causes Sudden Hearing Loss?
Despite its sudden onset, the exact causes of SSNHL are not always clear in the majority of cases. That’s the reason its termed “idiopathic”However, research suggests that it may be related to:

  1. Viral infections:
    Viruses such as measles, mumps, and rubella can cause inflammation in the inner ear called “cochleitis’, leading to hearing loss. Sometimes it may be a manifestation of a widespread viral infection.
  2. Blood flow problems:
    Reduced blood flow to the inner ear can cause damage to the hair cells, leading to hearing loss.
  3. Head trauma:
    A head injury can cause damage to the inner ear or the nerves that connect the inner ear to the brain.
  4. Ototoxicity:
    Exposure to certain chemicals or medications, such as antibiotics or chemotherapy, can damage the hair cells in the inner ear.
  5. Autoimmune disorders:
    Conditions such as rheumatoid arthritis or lupus can cause the immune system to attack the inner ear, leading to hearing loss.
  6. Loud noise exposure:
    Sudden burst of loud noise can also lead to sudden hearing loss.
