Nerve Palsies are characterised by the simultaneous dysfunction of more than one cranial nerve.
This condition can be seen in a serious underlying neurological, infectious, neoplastic, or inflammatory disorder.
Common Causes
- Neoplastic:
Skull base tumours (e.g., nasopharyngeal carcinoma, meningioma, metastases)
Lymphoma or leukemia
Schwannomas
- Infectious:
Tuberculosis
Lyme disease
Fungal infections (e.g., mucormycosis in diabetics)
HIV-related infections
Brain abscess
- Inflammatory/Autoimmune:
Sarcoidosis
Multiple sclerosis
Vasculitis (e.g., granulomatosis with polyangiitis)
- Vascular:
Cavernous sinus thrombosis
Stroke affecting the brainstem or cranial nerve nuclei
- Trauma:
Skull base fractures
Iatrogenic (post-surgery)
- Idiopathic:
Tolosa-Hunt syndrome (painful ophthalmoplegia)
Idiopathic hypertrophic pachymeningitis
Symptoms that are observed according to the nerve affected
I – Olfactory nerve
Function- Smell
Symptoms when palsied- Anosmia or hyposmia; altered taste (because flavour perception drops)
II – Optic
Function- Vision, pupillary reflex
Symptoms when palsied- Visual-field cuts, decreased acuity, impaired afferent pupillary light reflex (RAPD)
III – Oculomotor
Function- Eyelid elevation, most extraocular movements, pupil constriction
Symptoms when palsied- Ptosis, “down-and-out” eye, diplopia, dilated/non-reactive pupil, reading difficulty
IV – Trochlear
Function- Superior oblique muscle
Symptoms when palsied- Vertical diplopia (worse on looking down & in), head tilt away from the lesion
V – Trigemina
Function- Facial sensation, muscles of mastication, corneal reflex (afferent)
Symptoms when palsied- Facial numbness or pain, weak bite, jaw deviation toward lesion, absent corneal blink
VI – Abducens
Function- Lateral rectus
Symptoms when palsied- Horizontal diplopia, inability to abduct the eye, inward squint
VII – Facial
Function- Facial expression, taste (ant.. 2⁄3 tongue), lacrimation, salivation, stapedius
Symptoms when palsied- Facial droop, loss of forehead wrinkling, hyperacusis, loss of taste anterior tongue, dry eye/mouth
VIII – Vestibulocochlear
Function- Hearing, balance
Symptoms when palsied- Sensorineural hearing loss, tinnitus, vertigo, nystagmus, unsteady gait
IX – Glossopharyngeal
Function- Taste (post. 1⁄3), swallowing, carotid sinus reflex
Symptoms when palsied- Loss of gag (afferent), dysphagia, impaired taste posterior tongue, hoarse cough
X – Vagus
Function- Palate/larynx muscles, parasympathetic thoraco-abdominal
Symptoms when palsied- Nasal speech, hoarseness, palatal droop/uvula deviation away from lesion, dysphagia, autonomic instability
XI – Accessory
Function- Sternocleidomastoid & trapezius
Symptoms when palsied- Weak shoulder shrug, difficulty turning the head opposite side
XII – Hypoglossal
Function- Tongue movement
Symptoms when palsied- Tongue deviation toward lesion, dysarthria, fasciculations/atrophy
- Common Patterns:
1.Cavernous sinus syndrome: CN III, IV, V1, V2, VI
Ophthalmoplegia, ptosis, fixed/dilated pupil, facial numbness in V1/V2 distribution, painful red eye
- Jugular foramen syndrome (Vernet’s): CN IX, X, XI
Dysphonia, dysphagia, loss of gag, palate droop, weak SCM/trapezius
- Collet-Sicard syndrome: CN IX, X, XI, XII
tongue deviation/atrophy; profound swallowing & speech difficulty
- Brainstem lesion: May affect multiple CNs depending on location
Progressive unilateral SNHL & vertigo, facial weakness or numbness, absent corneal reflex
- Diagnosis and Evaluation:
MRI/CT of the brain and skull base
CSF analysis (for infection/inflammation)
Blood tests (e.g., ANA, ACE, HIV, TB)
Angiography is used if a vascular cause is suspected
- Homeopathy offers a supportive approach for managing symptoms of multiple cranial nerve palsies, especially in chronic or less acute stages.

FAQ’s
- What are multiple cranial nerve palsies?
-Multiple cranial nerve palsies refer to the simultaneous dysfunction of two or more cranial nerves, which can lead to a combination of symptoms like facial weakness, double vision, hearing loss, and difficulty swallowing.
- What causes multiple cranial nerve palsies?
Causes include:
-Infections: Meningitis, tuberculosis, Lyme disease
-Tumours: Skull base tumours, metastases, acoustic neuroma
-Inflammatory conditions: Sarcoidosis, Guillain-Barré syndrome
-Vascular issues: Stroke, aneurysms
-Trauma: Head injuries
-Idiopathic: Unknown causes (rare)
- Which cranial nerves are most commonly affected?
-It varies depending on the underlying cause. Commonly involved nerves include:
-CN III (Oculomotor)
-CN VI (Abducens)
-CN VII (Facial)
-CN IX (Glossopharyngeal)
-CN X (Vagus)
- What are the symptoms of multiple cranial nerve palsies?
Symptoms depend on the nerves involved and may include:
-Drooping eyelid (ptosis)
-Double vision (diplopia)
-Facial paralysis or weakness
-Difficulty swallowing or speaking
-Hearing loss or tinnitus
-Loss of sensation or taste
- How is it diagnosed?
Diagnosis typically involves:
-Neurological examination
-MRI or CT scans
-Blood tests
-Lumbar puncture (if infection or inflammation is suspected)
- Is it life-threatening?
-It can be, depending on the cause. Prompt evaluation is essential. Some causes (e.g., brain tumours or stroke) can be serious, while others (e.g., viral infections) may resolve with treatment.
- What is the treatment?
Treatment depends on the cause:
-Antibiotics or antivirals for infections
-Steroids or immunosuppressants for inflammatory causes
-Surgery or radiation for tumours
-Supportive therapy, like speech or physical therapy
- Can it be cured?
-Some cases are reversible, especially when the cause is treated early (e.g., infections, inflammation). Chronic or tumour-related cases may require long-term management.
- How long does recovery take?
-Recovery time varies widely—from weeks to months—depending on the cause and the severity of nerve damage.
- When should I see a doctor?
-Seek immediate medical attention if you experience sudden facial weakness, vision changes, or difficulty swallowing or speaking.
