Sudden Hearing Loss in One Ear: Causes, Risks, and Treatments
Contact Us
Sudden hearing loss in one ear can be a frightening and disorienting experience. One moment everything sounds normal and the next, it’s as if someone has hit the mute button on one side. While it may be tempting to ignore or hope it resolves on its own, this type of hearing loss requires immediate medical attention. In many cases, early intervention can significantly improve the chances of recovery.
In this blog, we’ll explore the common causes, risk factors, and treatment options for sudden hearing loss in one ear. If you're looking for the best ENT specialist in Dubai or hearing loss treatment in Dubai, understanding this condition is your first step toward effective care.
Understanding Sudden Hearing Loss: What Is It?
Sudden hearing loss in one ear, medically referred to as Sudden Sensorineural Hearing Loss (SSNHL), is characterized by a rapid and often unexplained reduction in hearing. It usually develops over a period of a few hours to a few days and affects the inner ear or auditory nerve, which is responsible for transmitting sound signals to the brain.
Common symptoms of sudden hearing loss in one ear include:
- A sensation of muffled or blocked sound in one ear
- Tinnitus (ringing or buzzing)
- Dizziness or vertigo
- A feeling of pressure or fullness in the ear
While the exact cause may remain unknown in many cases, research shows that there are several risk factors and potential triggers that can contribute to this condition.
Risk Factors That Increase Your Chances
Although sudden hearing loss can occur without warning, certain lifestyle habits, medical conditions, and environmental exposures may increase your vulnerability.
Key risk factors include:
- Age (30–60 years): SSNHL is most common among middle-aged adults.
- Chronic medical conditions: Diabetes, high blood pressure, and autoimmune disorders can compromise blood flow and nerve function in the inner ear.
- Ototoxic medications: Some antibiotics, diuretics, and chemotherapy drugs can damage the auditory nerve.
- Smoking: Tobacco use restricts blood flow and can impair inner ear function.
- Noise exposure: Prolonged exposure to loud environments or sudden loud noises can cause acute trauma.
- Family history: Genetics may also play a role in susceptibility.
If you identify with any of these risk factors and experience sudden hearing changes, it's critical to consult with the best ENT doctor in Dubai as early as possible.
Common Causes of Sudden Hearing Loss in One Ear
Let’s dive into the most likely causes of sudden hearing loss in one ear. While the condition can arise without a clear explanation, the following are commonly identified culprits:
1. Viral Infections
Viruses like herpes simplex, influenza, or mumps can affect the inner ear structures. These infections can cause inflammation of cochlea or auditory nerve, leading to temporary or permanent hearing loss.
- Inflammation may disrupt nerve signal transmission
- Often accompanied by fever or cold symptoms
2. Ototoxic Medications
Medications known as ototoxic drugs can damage the hair cells in the cochlea or the auditory nerve itself. Examples include:
- Aminoglycoside antibiotics (e.g., gentamicin)
- Chemotherapy drugs (e.g., cisplatin)
- NSAIDs (e.g., ibuprofen in high doses)
If you're under treatment involving these medications, regular hearing assessments from the best ear doctor in Dubai are strongly advised.
3. Inner Ear Disorders
Two inner ear conditions known to cause sudden hearing loss are:
- Meniere’s Disease: Characterized by vertigo, fluctuating hearing loss, tinnitus, and a feeling of fullness in the ear. While the cause is unknown, it's linked to abnormal fluid buildup in the ear.
- Labyrinthitis: Typically caused by a viral infection, this condition leads to inflammation in the inner ear’s labyrinth. Symptoms include dizziness, nausea, and sudden hearing loss.
Early diagnosis and treatment by a sinus doctor in Dubai or ENT specialist can make a significant difference in long-term outcomes.
4. Autoimmune Inner Ear Disease (AIED)
AIED is a rare condition where the immune system mistakenly attacks inner ear tissues, leading to progressive or sudden hearing loss. It may occur alone or alongside other autoimmune diseases such as lupus or rheumatoid arthritis.
Treatment often involves immunosuppressants or steroids, which require oversight by experienced specialists at leading centers like Tarabichi ENT, widely regarded as the best ENT clinic in Dubai.
5. Vascular Issues
Reduced blood flow or vascular blockages in the inner ear can cause oxygen deprivation, damaging the sensitive structures involved in hearing. Possible vascular causes include:
- Microvascular embolism
- Vasospasm (narrowing of blood vessels)
- Stroke affecting the auditory pathways
These events require urgent medical intervention, typically involving imaging studies and audiometric evaluations.
6. Trauma or Injury
Sudden hearing loss can also result from:
- Head trauma (sports injuries, car accidents, falls)
- Barotrauma (sudden pressure changes during flying or diving)
- Loud noise exposure (e.g., explosions or gunfire)
Protective measures and prompt ENT evaluation are essential to mitigate permanent damage.
7. Tumors (e.g., Acoustic Neuroma)
Although rare, tumors such as acoustic neuroma can develop on the vestibulocochlear nerve. These benign growths press against the nerve, disrupting hearing and balance.
Common symptoms include:
- Unilateral hearing loss
- Tinnitus in one ear
- Balance issues
Diagnosis typically involves MRI scans and referral to a best ENT surgeon in Dubai for further management.
Why Immediate Medical Attention is Crucial
Sudden hearing loss should never be ignored. According to ENT experts, the first 72 hours after symptom onset are critical. Treatment during this window, especially with corticosteroids, can lead to full or partial recovery in many cases.
At Tarabichi ENT, we offer:
- Comprehensive audiometric testing
- MRI/CT imaging to rule out tumors or vascular causes
- Personalized medical and surgical management plans

Treatment Options and Recovery Outlook
Treatment strategies depend on the underlying cause and the severity of the hearing loss. Here are some commonly used approaches:
Corticosteroids
Often administered orally or via intratympanic injections, corticosteroids help reduce inflammation in the inner ear and improve recovery chances.
Antiviral or Antibiotic Therapy
If an infection is suspected, antiviral drugs or antibiotics may be prescribed to combat the cause.
Hyperbaric Oxygen Therapy (HBOT)
This specialized treatment increases oxygen delivery to the inner ear tissues, which can aid recovery in some cases.
Surgical Intervention
In rare cases, especially involving tumors or structural damage, surgery may be required. The best ENT surgeons in Dubai, including those at Tarabichi ENT, are experienced in performing these delicate procedures.
