Regeneration time depends on how seriously your nerve was injured and the type of injury that you sustained. If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of 'rest' following your injury.

NYU Langone doctors monitor nerve function as it returns using tests such as electromyography. For those who have had decompression or reanimation surgery, recovery varies depending on the procedure.
Why does my eyelid dry out?
If the eyelid cannot move or blink, the eye is always exposed to the air, causing it to dry out. Dry eye leaves the eye vulnerable to injury from dirt and other airborne elements. Doctors recommend using lubricating eye drops frequently throughout the day and taping the eye closed at night.

Why is Bell's palsy so severe?
Because the facial nerve has so many functions and is so complex, damage to the nerve or a disruption in its function can lead to many problems. Symptoms of Bell's palsy can vary from person to person and range in severity from mild weakness to total paralysis. The most common symptom is sudden weakness of one side of the face.
What is Bell's palsy?
Bell's palsy, also known as idiopathic facial palsy, is a form of temporary facial paralysis or weakness on one side of the face. It results from dysfunction of cranial nerve VII (facial nerve) which directs the muscles on one side of the face, including those that control eye blinking and closing and facial expressions such as smiling.
What causes facial paralysis?
Several other conditions can also cause facial paralysis, for example, brain tumor, stroke, myasthenia gravis, and Lyme disease . If no specific cause can be identified, the condition can be diagnosed as Bell's palsy. top.

A diagnosis of Bell's palsy is made based on clinical presentation—acute facial nerve weakness or paralysis on one side of the face with onset in less than 72 hours— and by ruling out other possible causes of facial paralysis. There is no specific laboratory test to confirm diagnosis of the disorder. Generally, a physician will examine the ...

What is the best treatment for facial nerve palsy?
Corticosteroids for idiopathic facial nerve palsy. Corneal drying must be prevented by frequent use of natural tears, isotonic saline, or methylcellulose drops and by intermittent use of tape or a patch to help close the eye, particularly during sleep. Tarsorrhaphy is occasionally required.
Which nerve innervates the facial muscles?
The facial muscles are innervated peripherally (infranuclear innervation) by the ipsilateral 7th cranial nerve and centrally (supranuclear innervation) by the contralateral cerebral cortex. Central innervation tends to be bilateral for the upper face (eg, forehead muscles) and unilateral for the lower face.
What causes a swollen nerve in the face?
The swollen nerve is maximally compressed as it passes through the labyrinthine portion of the facial canal, resulting in ischemia and paresis. Various other disorders (eg, diabetes , Lyme disease , ...

Paresis, often with complete paralysis, develops within hours and is usually maximal within 48 to 72 hours. Patients may report a numb or heavy feeling in the face. The affected side becomes flat and expressionless; the ability to wrinkle the forehead, blink, and grimace is limited or absent.
Is facial nerve palsy idiopathic?
About half the cases of facial nerve palsy are idiopathic. The mechanism for what was previously thought to be idiopathic facial nerve palsy is presumably swelling of the facial nerve due to an immune or viral disorder. Current evidence suggests that common viral causes are. Herpes simplex virus infection (most common)
Is a sensory examination normal?
Sensory examination is normal, but the external auditory canal and a small patch behind the ear (over the mastoid) may be painful to the touch. If the nerve lesion is proximal to the geniculate ganglion, salivation, taste, and lacrimation may be impaired, and hyperacusis may be present.
Can you move your face on one side?
In facial nerve palsy, patients cannot move the upper and lower part of their face on one side; in contrast, central facial nerve lesions (eg, due to stroke) affect primarily the lower face.

In patients with a facial nerve palsy or paralysis, the aim of treatment, reconstruction and reanimation is a balance of restoring function, achieving cosmesis and reducing morbidities associated with surgery.
What is facial reanimation?
Facial re-animation with free muscle transfer is now the standard of care in appropriate patients with facial nerve palsy. Outcomes from free muscle transfers are recognised as providing results superior to cranial nerve transfer or local muscle transposition. This technique involves both neural control and muscle recruitment.
What nerves are used for grafting?
Nerve grafting should go beyond the zone of injury. Donor nerves for this technique include: Greater auricular nerve – 10 cm length, proximity to operative field. Sural nerve – 35cm length that can be neurolysed as segments 5 and allows a two-team approach with minimal donor-site morbidity.

NYU Langone otolaryngologists—also known as ear, nose, and throat (ENT) doctors—specialize in diagnosing facial nerve paralysis. An early diagnosis can dramatically improve the chances that doctors can restore muscle function.
How long does it take for an electroneurography to show paralysis?
Electroneurography is a test used to evaluate the function of peripheral nerves, which include the facial nerve. Ideally, this test is performed within 14 days of the onset of paralysis. The results help doctors determine whether further testing or intervention may be required.
What is an electromyogram?
During an electromyogram, a doctor inserts small, thin needle electrodes through the skin and into facial muscles that correspond to specific nerves. He or she then asks you to move these muscles if you can.
