Can Lyme Disease Cause Sudden Hearing Loss and Facial Palsy?
Can Lyme disease cause sudden hearing loss?
In some cases, yes—and it can happen months or even a year after a tick bite.
Sudden hearing loss, tinnitus, dizziness, facial weakness, or neck stiffness may reflect neurologic Lyme disease involving the cranial nerves and meninges.
This distinction matters because hearing loss caused by infection-related inflammation may be reversible when recognized early and treated appropriately.
For a broader overview, see neurologic Lyme disease.
Sudden Hearing Loss From Neuroborreliosis
In their article “Lyme neuroborreliosis as a cause of sudden sensorineural hearing loss and facial palsy”, Nitro and colleagues describe a woman in her 40s who developed sudden loss of hearing in both ears along with facial palsy and was later diagnosed with Lyme meningitis.
“Bilateral hearing loss is rare,” the authors point out.
The patient presented to the emergency department with hearing loss in both ears, tinnitus, dizziness, neck pain, and stiffness. Her symptoms had been ongoing for three days.
She was initially treated overnight with amoxicillin/clavulanate for a presumed ear infection.
However, her condition rapidly evolved.
“During the night, a new urgent neurological consult was requested following sudden right facial palsy,” the authors wrote.
Hearing loss followed by rapidly progressive facial weakness may suggest inflammation involving multiple cranial nerves.
Rapidly Progressive Lyme Facial Palsy
The patient was treated with intravenous methylprednisolone, valaciclovir, and ceftriaxone to address several possible neurologic causes.
Over the next two days, her neck pain improved, but her hearing loss and facial palsy did not.
This mixed response increased concern for persistent neurologic inflammation.
Facial palsy associated with hearing loss and dizziness may indicate broader nervous system involvement than isolated Bell’s palsy.
Lyme Meningitis Diagnosed One Year After Tick Bite
Further questioning revealed an important clue.
One year earlier, the patient had removed a tick from her right ear canal.
Testing later confirmed Lyme disease, and MRI imaging demonstrated findings consistent with Lyme meningitis involving multiple cranial nerves.
The inflammatory findings affected:
- Cranial nerve VII, associated with facial movement
- Cranial nerve VIII, associated with hearing and balance
This delayed connection between tick exposure and neurologic symptoms is one reason Lyme disease may be overlooked.
Can Lyme Disease Sudden Hearing Loss Be Reversible?
The patient was treated with intravenous steroids and ceftriaxone.
“At the end of the therapy, the patient showed a complete resolution of the meningeal inflammation, facial palsy, and sensorineural hearing loss.”
This outcome is clinically important because it demonstrates that Lyme-related neurologic hearing loss may improve when infection-related inflammation is recognized and treated.
The authors noted:
“The most challenging feature of this case was identifying a diagnostic connection between SSNHL [sudden sensorineural hearing loss] and rapidly progressive unilateral facial palsy.”
Why Lyme Disease Hearing Loss Is Missed
Sudden hearing loss alone has many possible causes, including viral infection, vascular injury, autoimmune disease, tumors, or medication toxicity.
Facial palsy may suggest Bell’s palsy or Ramsay Hunt syndrome.
However, when hearing loss, tinnitus, dizziness, facial weakness, and neck stiffness occur together, clinicians should also consider infectious causes such as Lyme meningitis.
This diagnostic overlap contributes to Lyme disease misdiagnosis, particularly in patients without a recalled rash.
Why Symptoms May Appear Months Later
Lyme disease may progress gradually over time.
After initial infection, Borrelia bacteria may persist and later affect the nervous system through inflammatory or immune-mediated mechanisms.
The authors emphasized that:
“One of the most peculiar features of neuroborreliosis can manifest up to 1 year after a disseminated infection.”
Possible contributors to delayed symptoms include immune system changes, gradual spread to the nervous system, and delayed inflammatory responses.
This is one reason clinicians should ask about tick exposure from the prior year when evaluating unexplained neurologic symptoms.
Frequently Asked Questions
Can Lyme disease cause sudden hearing loss?
Yes. Lyme disease may affect cranial nerve VIII and lead to hearing loss, tinnitus, dizziness, or balance problems.
Can Lyme-related hearing loss improve with treatment?
In some cases, yes. Hearing loss related to infection-associated inflammation may improve with antibiotics and anti-inflammatory treatment.
Why are facial palsy and hearing loss connected?
Both symptoms may occur when Lyme neuroborreliosis affects multiple cranial nerves, particularly cranial nerves VII and VIII.
How long after a tick bite can neurologic symptoms appear?
Neurologic symptoms may appear months or even a year after tick exposure.
What is Lyme meningitis?
Lyme meningitis is a form of neurologic Lyme disease involving inflammation of the membranes surrounding the brain and spinal cord.
Clinical Takeaway
Lyme disease can occasionally present with sudden hearing loss, tinnitus, dizziness, and rapidly progressive facial palsy.
Because these symptoms overlap with viral, autoimmune, and vascular disorders, diagnosis may initially be missed.
I have seen patients with tinnitus, dizziness, facial symptoms, and hearing complaints whose Lyme disease diagnosis was delayed because the connection between neurologic symptoms and prior tick exposure was not initially recognized.
Recognizing the relationship between hearing loss, cranial nerve symptoms, and prior tick exposure may allow earlier diagnosis and improve the likelihood of recovery.

Hi Dr. Cameron, I’m one of your patients for Lyme Disease. I have had bad tinnitus for several years. It is inconsistent, comes and goes. But at times it is extremely loud. Could this be a result of Borrelia? Thanks, Rebecca
I have patients with tinnitus who so well with treatment for Lyme disease.
Hi
I have off and on tinnitus. Thinking I was loosing my hearing I bought a pair of hearing aids from the tv. Can’t figure how to use them. Facial palsy, mine started below the left eye year and half ago I suppose. Last few months it’s both sides of face and sometimes my whole head.
So many strange symptoms with this Lyme and Babesia.
My blood work changes, kidney issues, then Liver enzymes are high. My cholesterol levels over the top. I thing LDL is over 200. Overall is 278. Never had issues.
I’m obsessed with worries of these ever changing symptoms. I can’t get out and walk, jog, or run 1/2 marathons anymore. Lack of the exercises I done before I know contribute to the cholesterol numbers but what do we do when we’re falling apart inside. Because we look decent on the outside. People think we are just fine.
I’m Debbie, I’m struggling with lyme for over a year. Severe rt. ear pain, neuropathy like, left ear has mild pains . Severe jaw pain which shoots deep into my ear. Mild to severe dizziness and nausea. Neuropathy on my rt side from chest to toes. Leg, knee and foot are effected. Arthritis in my Rt. knee is bad, mild in left. My ENT feels the pain in my jaw is arthritis. The debilitating headaches and neck pain are helped tremendously with magnesium and turmeric. Potassium helps with other pains. Nothing helps my jaw . Nothing helps the horrible collagen loss and elasticity loss. Weight has dropped terribly. I was 130ish and went to a steady 119 lbs. I’ve been trying to gain anything and can’t. My memory is effected sporadically and is scary. I eat healthy, sober 38 yrs. in AA, no illicit drugs, go to yoga, art class, therapy for depression etc, but can’t find any Dr that can help me. I’m seeing a new neuro., rheumatologist, oral surgeon eventually, cardiologist, endocrinologist. I’ve seen 4 I.D. Drs who were invalidating, challenging, disrespectful, causing me to feel victimized not supported or helped. I research lyme and bought a book, which is where I get validation and knowledge. In a year I’ve met 31 other (what I call) Lyme-A-Ticks and we feel like Luna-ticks because we can’t get the help we need and deserve. I’m coordinating a support group as soon as I feel healthier. If you feel you can help PLEASE let me know. I really appreciate your time.
I am sorry you have struggled. Call my office at 914 666 4665 if you are interested in an evaluation.
