Facial Paralysis

1. What is Facial Paralysis?

Facial paralysis is the loss of voluntary movement of the muscles on one side (or, rarely, both sides) of the face. These muscles are controlled by the facial nerve — the seventh cranial nerve — which leaves the brainstem, travels through a narrow bony canal inside the skull near the ear, and then spreads like the fingers of a hand to supply the forehead, eyelids, cheeks, lips and chin.

When this nerve or its control centre in the brain is damaged, the face on that side may droop, the eye may not close completely, the mouth may pull to the opposite side when smiling, and food or fluids may escape from the corner of the mouth. Because the face is so central to communication and identity, facial paralysis often causes significant emotional distress in addition to physical difficulty.

Facial paralysis is a sign with many possible causes — from Bell’s palsy, which is usually temporary, to stroke, which is a medical emergency. A correct diagnosis is therefore the essential first step. Classical Ayurveda describes a closely related condition called Ardita (अर्दित), a Vata disorder of the head and face, with detailed descriptions of its features, prognosis and treatment.

2. Who is affected?

Facial paralysis can occur at any age. Bell’s palsy is most common between 15 and 60 years and is more frequent in pregnant women, people with diabetes and those recovering from viral infections. Stroke-related facial weakness is more common in older adults and in people with high blood pressure, diabetes, heart disease or smoking habits. Injuries, ear infections, tumours and some systemic diseases can cause facial nerve damage in any age group.

3. Types of facial paralysis

• Peripheral (lower motor neuron) facial palsy — the nerve itself is affected, so the whole half of the face, including the forehead, is weak. Bell’s palsy is the most common example.
• Central (upper motor neuron) facial weakness — the brain’s control centre is affected, usually by stroke; the forehead is typically spared and the lower face droops.
• Partial palsy — some movement is preserved.
• Complete palsy — no voluntary movement on the affected side.
• Recurrent or bilateral palsy — uncommon and needs detailed investigation.

The difference between central and peripheral types is extremely important: central facial weakness accompanied by arm or leg weakness or speech difficulty may indicate a stroke and needs emergency care.

4. Common symptoms

• Drooping of the eyebrow, eyelid or corner of the mouth on one side
• Inability to close the eye fully, leading to dryness, watering or irritation
• Difficulty smiling, whistling, puffing the cheeks or raising the eyebrows
• Food collecting in the cheek and drooling while drinking
• Altered or reduced taste on the front of the tongue
• Increased sensitivity to loud sounds on the affected side
• Pain behind the ear before or at the onset (in Bell’s palsy)
• Slurred speech due to lip weakness

5. Causes and risk factors

• Bell’s palsy — inflammation and swelling of the facial nerve inside its bony canal, often linked to viral infections such as herpes simplex.
• Stroke — interruption of blood supply to the brain’s motor areas.
• Ramsay Hunt syndrome — shingles infection of the facial nerve, with a painful rash near the ear.
• Ear infections and mastoiditis.
• Head injury or facial trauma, including fractures of the skull base.
• Tumours — of the parotid gland, ear or brain (uncommon).
• Systemic conditions — diabetes, Lyme disease, sarcoidosis and others.
• Surgery near the ear or parotid gland.

Exposure to cold wind, physical and emotional stress, lack of sleep and lowered immunity are commonly reported triggers for Bell’s palsy.

6. How is facial paralysis diagnosed?

1. Careful history — speed of onset, pain, rash, hearing change, injury and associated weakness of limbs or speech.
2. Examination of each facial muscle group, eye closure, taste and hearing, along with a neurological examination of the limbs.
3. Distinction between central and peripheral palsy, with urgent referral if stroke is suspected.
4. Investigations as required — blood sugar, ear examination, imaging (CT/MRI) or nerve conduction tests in selected cases.
5. Ayurvedic evaluation of the dosha involvement, strength, digestion and associated conditions.

7. The Ayurvedic perspective

Ardita is described by Acharya Charaka and Sushruta as a condition in which aggravated Vata, often provoked by exposure to cold wind, loud speaking, chewing hard foods, yawning widely, carrying heavy loads on the head, sleeping in uncomfortable positions or emotional stress, affects the head and face. The face becomes twisted (vakri bhavati), the neck may stiffen, speech is affected and the eye on one side cannot close.

The classics note that Ardita may involve Vata alone or be associated with Pitta (burning, fever) or Kapha (swelling, heaviness), and that early treatment carries a better outlook. Treatment principles include Snehana (oleation), Swedana (fomentation), Nasya (nasal medication), Murdha Taila (oil therapies for the head such as Shiro Abhyanga and Shirodhara), Tarpana for the eye, and Vata-pacifying internal medicines.

8. Treatment approaches at Manojivan

• Diagnosis first — stroke and other emergencies are excluded before therapy begins.
• Nasya — medicated oil drops in the nose, a key classical therapy for disorders above the shoulders.
• Mukha Abhyanga — gentle facial massage with medicated oil following the direction of muscle movement.
• Swedana — mild facial fomentation (such as Nadi Sweda or Patra Pinda Sweda) to relieve stiffness.
• Shiro Abhyanga and Shirodhara — for calming Vata, improving sleep and reducing stress.
• Eye care — protection, lubrication and, where suitable, Netra therapies under supervision.
• Internal medicines — Vata-pacifying and nerve-supporting formulations chosen by the physician.
• Facial exercises — guided practice in front of a mirror to retrain muscles.

Facial paralysis due to stroke, tumour or injury needs specialist medical care. Ayurvedic therapies are offered as supportive care after the diagnosis is confirmed.

11. Lifestyle and self-care

• Protect the affected eye: use lubricating drops as advised, wear glasses outdoors and tape or patch the eye at night if it does not close.
• Avoid direct cold wind, air-conditioner or fan air on the face.
• Practise facial exercises several times a day — raising eyebrows, gently closing eyes, smiling, puffing cheeks and whistling — without straining.
• Chew on both sides and clean the mouth after meals to remove trapped food.
• Get adequate sleep and manage stress; anxiety can slow recovery.
• Keep blood sugar and blood pressure under control if you have diabetes or hypertension.

12. What to expect during recovery

Recovery depends on the cause and the extent of nerve injury. In Bell’s palsy, many patients begin to see movement return within a few weeks and continue to improve over three to six months. More severe nerve damage may take longer and may leave mild residual weakness or “synkinesis” (unintended movement of one part of the face when moving another). Regular therapy, eye protection and exercises help maximise recovery, and the treatment plan is reviewed at each follow-up.

13. How the facial nerve works

The facial nerve carries several kinds of fibres. Motor fibres move the muscles of facial expression; other fibres carry taste from the front two-thirds of the tongue, control the tear and salivary glands, and supply a tiny muscle in the middle ear that dampens loud sounds. This is why facial paralysis can be accompanied by changes in taste, dry eye or watering, altered saliva and sensitivity to sound. During its course the nerve passes through one of the narrowest bony canals in the body; when it swells, as in Bell’s palsy, it has little room to expand, and this pressure is believed to cause much of the temporary loss of function.

14. Your care journey at Manojivan

1. Assessment — confirmation of the diagnosis, grading of facial weakness, eye examination and review of any scans or reports.
2. Plan — a written plan covering therapies, medicines, eye protection and exercises, with realistic expectations explained.
3. Therapy phase — a supervised course of Nasya, facial Abhyanga, fomentation and head therapies, typically over one to three weeks.
4. Home programme — facial exercises, eye care, diet and lifestyle measures practised daily at home.
5. Follow-up — regular reviews to track recovery and adjust treatment.

15. Emotional wellbeing

A change in facial appearance can affect confidence, social life and work. It is common to feel embarrassed, anxious or low, especially in the first weeks. Reassurance that many forms of facial palsy improve with time, support from family, and calming therapies such as Shirodhara can help. Patients are encouraged to share their concerns with the doctor; where needed, we also suggest counselling support.

16. When to seek medical attention

17. A closer look: protecting the eye

When facial paralysis prevents the eyelid from closing fully, the eye can become dry and the cornea vulnerable to injury. Eye protection is therefore a priority: lubricating eye drops during the day and ointment at night as prescribed, taping the eyelid gently closed at night if advised, wearing glasses outdoors to protect against dust and wind, and seeking urgent care for eye pain, redness or blurred vision.

18. Common myths and facts

• Myth: Facial paralysis is always permanent. Fact: Many cases, particularly Bell’s palsy, improve significantly over weeks to months.
• Myth: It is caused by evil eye or a curse. Fact: Facial paralysis has medical causes such as nerve inflammation, infection or stroke, and it needs proper diagnosis.
• Myth: Hot fomentation can be done at home as much as possible. Fact: Excessive heat can burn the skin and harm the eye; fomentation should be mild and supervised.
• Myth: Exercises are not important. Fact: Regular, gentle facial exercises help retrain muscles and are a key part of recovery.

19. Prevention

Not all facial paralysis can be prevented, but controlling blood pressure, blood sugar and cholesterol, avoiding smoking and managing stress reduce the risk of stroke. Protecting yourself from cold wind after illness, getting adequate rest and maintaining good immunity may reduce the risk of Bell’s palsy.
