What causes 6th nerve palsy in children?

The most common causes of sixth cranial nerve palsy are stroke, trauma, viral illness, brain tumor, inflammation, infection, migraine headache and elevated pressure inside the brain. The condition can be present at birth; however, the most common cause in children is trauma.

What causes palsy of the sixth cranial nerve?

This is sometimes due to injury of the sixth cranial nerve during labor or delivery. But sometimes the cause of congenital sixth nerve palsy is unknown. Various circumstances and illnesses can also cause the disorder. This includes a head injury or skull fracture that damages the sixth cranial nerve.

Can a person with sixth nerve palsy have both eyes?

Symptoms of sixth nerve palsy. Because each eye has its own lateral rectus muscle and sixth cranial nerve, sixth nerve palsy can affect one or both eyes. Your symptoms and the severity of the condition depend on whether both eyes are affected. Double vision is the most common symptom of sixth nerve palsy.

How is trochlear nerve palsy related to trauma?

Trochlear nerve palsy can also occur as part of a broader syndrome related to causes like trauma, neoplasm, infection, and inflammation. These etiologies are further categorized based on the anatomic location of involvement (midbrain, subarachnoid space, cavernous sinus, orbit).

Which is the second most common cause of CN IV palsy?

Microvascular ischemia is the second most common cause of acquired CN IV palsy. It is uncommon to see an isolated CN IV palsy from lesions in the cavernous sinus given the presence of other cranial nerves passing though this space.

Which is the most common etiology of acquired CN IV palsy?

Consequently, it is especially susceptible to damage in the setting of head trauma. Trauma accounts for roughly 44% of acquired trochlear nerve palsies with nearly 25% of cases being bilateral and, thus, it is the most common etiology of an acquired CN IV palsy [1].

Can a frontal impact cause bilateral CN IV palsy?

Occipital and frontal impact can give rise to bilateral CN IV palsies due to a contusion at the point of decussation of the nerves or a unilateral palsy due to either compression or shearing of the individual nerve by the tentorium. Damage to CN IV can even occur in the setting of seemingly minor head trauma without loss of consciousness.
