EMERGENCY:Bell's palsy with incomplete eye closure (lagophthalmos) is a corneal emergency. If the eye cannot close, the cornea will dry out and develop exposure keratopathy. Artificial tears every hour during the day and eye tape at night are mandatory until eye closure recovers. —call040-46324365immediately — 24 hours, 7 days— 24/7
Bell's Palsy in Hyderabad: The Suddenly Drooping Face, the Pain Behind the Ear, and Why Starting Prednisolone Today — Not Next Week — Changes the Recovery
Expert same-day Bell's palsy assessment, House-Brackmann grading, 72-hour prednisolone start, eye protection prescription, valaciclovir for Ramsay Hunt syndrome, mirror-biofeedback physiotherapy, botulinum toxin for synkinesis, and MRI of the facial nerve when indicated by the KIMS Neuroscience team, Secunderabad, Hyderabad.
Bell's palsy is acute unilateral peripheral facial nerve (CN VII) palsy — the most common cause of sudden facial weakness. Caused by presumed reactivation of herpes simplex virus type 1 (HSV-1) in the geniculate ganglion, producing inflammation and swelling within the narrow facial canal. The critical bedside distinction from stroke: in Bell's palsy (lower motor neuron), the entire face including the forehead is weak. In a stroke (upper motor neuron), the forehead is spared due to bilateral cortical representation. 85% of patients recover fully or near-fully with timely prednisolone. The 72-hour window is the most important intervention window in all of cranial nerve medicine: prednisolone 50mg/day for 10 days, started within 72 hours. Lagophthalmos (inability to close the eye) is the most urgent immediate complication — corneal damage can occur within hours of exposure.
- The forehead test
- Bell's palsy: forehead WEAK (cannot raise eyebrow, cannot close eye). Stroke: forehead SPARED (bilateral cortical input). If forehead is completely weak AND no arm/leg signs — Bell's palsy. If any arm/leg weakness — 040-46324365.
- 72-hour prednisolone window
- Prednisolone 50mg/day for 10 days within 72 hours of onset. Starting after 72 hours: diminishing benefit. Starting after 7 days: no evidence of benefit. Start NOW.
- Lagophthalmos = corneal emergency
- Inability to close the eye (lagophthalmos) exposes the cornea. Corneal damage within hours in severe cases. Artificial tears hourly + lubricating ointment at night + micropore tape to close eyelid at night. NOT optional.
- Prognosis
- 85% full recovery with timely prednisolone. 15% residual weakness, synkinesis, or crocodile tears. Worst prognosis: complete palsy + no steroids. Best predictor of outcome: incomplete vs complete palsy at onset.
- Synkinesis (abnormal recovery)
- ~15% of Bell's palsy patients: nerve fibres regrow to wrong muscles. Smiling triggers eye closure. Eating triggers tears (Bogorad syndrome — crocodile tears). Develops 3–6 months post-palsy. Treatment: Botulinum toxin + mirror biofeedback.
- Ramsay Hunt syndrome
- Zoster involvement of geniculate ganglion — vesicles in the ear + facial palsy + ear pain. Worse prognosis than Bell's palsy. Add valaciclovir to prednisolone for any patient with ear vesicles.

About This Condition
Bell's Palsy at a Glance
The essential facts that shape how Bell's palsy is recognised, distinguished from stroke, and treated at KIMS — from the HSV-1 inflammation in the facial nerve canal and the demographic risk factors, to the forehead-test that distinguishes peripheral CN VII palsy from a central facial palsy, and the 85% full-recovery prognosis when prednisolone is started within 72 hours.
What it is
Bell's palsy is an acute, unilateral, peripheral facial nerve (CN VII) palsy — the most common cause of sudden facial weakness. It is caused by presumed reactivation of herpes simplex virus type 1 (HSV-1) in the geniculate ganglion of the facial nerve, producing nerve inflammation and swelling within the narrow facial nerve canal of the temporal bone. The resulting pressure produces nerve dysfunction ranging from mild weakness to complete facial paralysis. The condition is named after Sir Charles Bell, who first described the facial nerve anatomy and the syndrome in the 19th century.
Who it affects
Bell's palsy affects approximately 15–30 per 100,000 people annually — it is the most common acute mononeuropathy. It affects men and women equally; peak incidence is in the third decade of life, though it occurs at any age. Risk factors: pregnancy (3x higher risk, particularly in the third trimester); diabetes mellitus; immunosuppression; and prior Bell's palsy (5–10% recurrence risk, sometimes on the contralateral side).
The forehead distinction — Bell's palsy vs stroke
The single most important clinical examination finding: does the facial weakness involve the forehead? In Bell's palsy (lower motor neuron, peripheral CN VII palsy), the forehead is weak on the affected side — the patient cannot raise the affected eyebrow or wrinkle the forehead. In a stroke (upper motor neuron, central facial palsy), the forehead is spared because the forehead muscles receive bilateral cortical input from both cerebral hemispheres. A stroke that causes right lower face weakness typically leaves the right forehead intact (bilateral cortical representation). At KIMS, forehead involvement is the first examination finding assessed in any acute facial weakness.
Prognosis
85% of Bell's palsy patients recover fully or near-fully if treated promptly. Approximately 15% have residual weakness, synkinesis (involuntary facial movements), or crocodile tears. The most important determinant of outcome: completeness of the initial palsy and timing of steroid treatment. Complete palsy (no movement at all) recovers less completely than incomplete palsy. Starting prednisolone within 72 hours of onset is the most impactful intervention.

The Morning It Would Not Move
A 32-year-old woman in Hyderabad woke at 6am to find that the right side of her face was not moving. When she tried to smile in the mirror, only the left side lifted. When she tried to close her right eye, it would not fully close — the lower eyelid remained open, and she could see the white of the eye (sclera) when trying to squeeze the lids together. The previous evening she had noticed a dull ache behind the right ear, which she attributed to sleeping badly.
At KIMS, the clinical examination is systematic. Right-sided facial weakness affecting the entire right face: she cannot raise the right eyebrow, cannot wrinkle the right forehead, cannot close the right eye (Bell's phenomenon is demonstrated — on attempting to close the eye, the right eyeball rolls upward, revealing the white sclera below the open lower lid), cannot whistle, cannot puff the right cheek, and cannot show the right teeth. Left-sided forehead and face: completely normal. No arm or leg weakness. No speech disturbance. No visual change. Forehead involved = lower motor neuron palsy = Bell's palsy, not stroke.
House-Brackmann grade: V (severe dysfunction — only slight movement, incomplete eye closure). Prednisolone 50mg/day is started immediately. Artificial tear drops prescribed (every 1–2 hours during the day). Tape to close the right eye at night. Eye lubricating ointment at bedtime. Facial physiotherapy referral.
At 2-week review: slight movement returning to the right lower face. Eye closing approximately 80% at effort. House-Brackmann grade III. Prednisolone course completed. At 6-week review: full recovery of forehead and eye closure. Mild asymmetry on maximal smile. House-Brackmann grade II. At 3-month review: House-Brackmann grade I (normal function). Full recovery.

040-44885000Stroke / arm or leg weakness: 040-46324365Clinical Features
The clinical profile of Bell's palsy spans the sudden unilateral facial weakness often noticed on waking, the mastoid ear-pain prodrome that opens the steroid window, lagophthalmos as the most urgent corneal emergency, taste and hyperacusis from chorda-tympani and stapedius involvement, and synkinesis as the abnormal recovery pattern that develops months later.
Sudden onset unilateral facial weakness — often noticed on waking
The weakness in Bell's palsy develops rapidly — over hours to days — and is often noticed first thing in the morning when looking in the mirror. The onset is so abrupt that many patients assume they have had a stroke, and emergency department presentations are common. At KIMS, the systematic clinical examination (forehead involved vs spared; presence of arm, leg, or speech signs) resolves this concern rapidly.
Pain behind the ear — the prodrome that is often missed
Pain in the mastoid region (behind the ear), sometimes extending into the jaw or neck, frequently precedes the facial weakness by 1–3 days in Bell's palsy. This pain is produced by inflammation of the facial nerve within the mastoid portion of the facial nerve canal. Patients often attribute it to dental pain or lymph node tenderness. Recognising the ear pain as a prodrome is clinically important because it may provide additional hours within the 72-hour steroid window.
Incomplete eye closure (lagophthalmos) — the corneal emergency
The orbicularis oculi muscle (which closes the eye) is supplied by CN VII. In Bell's palsy, this muscle may be completely paralysed, preventing the eyelid from closing. When the eyelid cannot close, the cornea is exposed: it dries out, is vulnerable to dust and abrasion, and can develop exposure keratopathy (corneal ulceration from dryness) within days if unprotected. At KIMS, eye care instructions are given at the first visit: artificial tears every 1–2 hours during the day; swimming goggles or moisture chamber spectacles to protect the eye in dry or dusty environments; eye tape to close the eyelid at night; lubricating eye ointment at bedtime. This is not optional — corneal damage from lagophthalmos is the most preventable complication of Bell's palsy.
Taste disturbance and hyperacusis
The chorda tympani branch of CN VII carries taste fibres from the anterior two-thirds of the tongue. Damage to this branch (which leaves the main facial nerve trunk within the facial canal) produces loss of taste (dysgeusia or ageusia) on the ipsilateral side. The stapedius muscle in the middle ear is also supplied by CN VII; paralysis produces hyperacusis (sounds abnormally loud and painful on the affected side) because the stapedius normally dampens the vibration of the ossicular chain.
Synkinesis — the abnormal recovery pattern
In approximately 15% of Bell's palsy patients, the nerve fibres regenerate incorrectly — fibres that previously controlled one muscle group regrow to supply a different muscle group. This produces synkinesis: involuntary facial movement accompanying a voluntary movement. The most common form: when the patient smiles (activating the zygomatic muscles), the eye on the affected side involuntarily closes. Another: 'crocodile tears' (Bogorad syndrome) — the patient cries when eating, because fibres that previously supplied the salivary glands regrow to the lacrimal gland. Synkinesis develops 3–6 months after the initial palsy and responds to botulinum toxin injections and specific facial physiotherapy.

Treatment
Treatment at KIMS — Prednisolone, Antivirals, Eye Care & Physiotherapy
Bell's palsy treatment at KIMS centres on four integrated pillars — prednisolone within 72 hours, antivirals for Ramsay Hunt syndrome and severe / complete palsy, immediate eye protection to prevent corneal damage, and mirror-biofeedback physiotherapy with botulinum toxin for synkinesis. The 85% full-recovery figure depends on all four being delivered at the correct time.
Prednisolone, antivirals, eye protection & mirror-biofeedback physiotherapy
Prednisolone — start within 72 hours: 50mg/day for 10 days (some protocols: 60–80mg/day for 5 days then taper over 5 days). Starting within 72 hours of symptom onset significantly improves the proportion of patients achieving full recovery. Starting after 72 hours has diminishing but still positive benefit. There is no evidence of benefit if started more than 7 days after onset. Prednisolone should not be withheld based on mild severity — even mild Bell's palsy can progress to complete palsy within 24–48 hours.
Antivirals — aciclovir or valaciclovir: The role of antivirals remains debated. The BELL trial (Sullivan et al., BMJ 2007) showed prednisolone alone was superior to antivirals alone; prednisolone + aciclovir did not significantly outperform prednisolone alone. Current UK NICE guidance: prednisolone alone is sufficient for most patients. Some guidelines recommend prednisolone + valaciclovir for severe (complete) palsy or when Ramsay Hunt syndrome (zoster involvement of the geniculate ganglion, producing vesicles in the ear) is suspected. At KIMS, antivirals are added for severe or complete Bell's palsy and for any patient with ear vesicles.
Eye protection — the non-negotiable immediate priority: Artificial tear drops (preservative-free, e.g., Systane Ultra): hourly during waking hours until eye closure is complete. Lubricating eye ointment (Lacrilube or equivalent) at bedtime. Micropore tape to tape the eyelid closed during sleep (prevents corneal exposure overnight). Moisture chamber spectacles or swimming goggles for protection in dusty, windy, or dry environments. Ophthalmology referral if corneal staining or keratopathy develops.
Facial physiotherapy and mirror biofeedback: Specific exercises for the muscles of facial expression, beginning once any movement has returned (not during complete paralysis). Mirror biofeedback (the patient watches their facial movements in a mirror and corrects asymmetric patterns) and neuromuscular retraining reduce the development of synkinesis and improve symmetry. At KIMS, physiotherapy referral is made at the initial visit with instructions to begin exercises when movement returns.
