Overview
Facial paralysis can occur when the nerve controlling the facial muscles functions less well. Bell’s palsy, infection, trauma and other causes may look similar. Diagnosis is not made from appearance alone.
Call 112 if new facial asymmetry is accompanied by difficulty speaking or weakness of an arm or leg.
Reduced facial muscle movement may be noticed when smiling, closing the eyes or moving around the mouth. Because different causes can produce the same appearance, assessment is based on the time of onset and accompanying symptoms. Bell’s palsy is a diagnosis considered after a specific clinical assessment; a facial photograph cannot exclude all other causes. Priorities are to distinguish conditions requiring emergency assessment and identify functions needing protection, such as an eye that will not close.
When should you seek assessment?
An asymmetric smile
Incomplete eye closure
Reduced movement on one side of the face
If new facial asymmetry occurs with symptoms such as difficulty speaking, arm or leg weakness or sudden visual changes, seek emergency help by calling 112. Assessment should also not be delayed when a change in facial movement is the only symptom noticed. Ear pain, a rash, hearing changes, trauma or a similar previous episode are important in the history. Specifically report whether the eye closes and whether there is watering, dryness or visual discomfort.
Examination and assessment
Onset, ear symptoms and accompanying neurological symptoms are assessed. Facial nerve examination and, when necessary, hearing tests, imaging or electrophysiological tests are performed.
Examination assesses movement in different facial areas, protection of the eye and other nervous system findings. An ear examination and hearing assessment may be performed when needed. The same blood tests or imaging are not required for everyone; they are selected according to the history and findings. Assessment may be expanded for slowly progressive, recurrent or unexpectedly persistent conditions. Explaining the basis of the diagnosis and which changes require further investigation at the first visit is important for follow-up.
Treatment options
Medicines and follow-up are arranged according to the cause. If the eye does not close, care to protect the cornea is a priority. Rehabilitation or surgery is considered only in selected circumstances.
Treatment is arranged according to the likely cause and timing of presentation. Early medicine treatment may be considered in some circumstances, while other causes require different approaches. If the eye does not close fully, an individual care plan is provided to protect the corneal surface; its application should be demonstrated. Massage, electrical treatments or exercise programmes learned online are not suitable for everyone. The need for and method of rehabilitation are planned with the relevant healthcare professionals according to facial movement.
Recovery and follow-up
Recovery time varies with the cause and nerve involvement. Follow-up monitors eye health and the return of facial movement.
During recovery, the return of facial movements, eye symptoms and everyday functioning are monitored. Timing and outcome vary with the underlying cause and degree of nerve involvement. Some people develop involuntary associated contractions as movement returns; these require separate assessment. Follow-up is usefully based on eye health and difficulties speaking, eating and drinking as well as appearance. Any change that differs from the expected course should be reported to the healthcare team.
If the eye does not close, it is important to understand all care instructions. Eye pain, marked redness or reduced vision may require urgent eye assessment. The drops, protection method and frequency of checks are individualised; do not apply unselected products to the eye. Facial movement changes can also affect social life and emotional well-being. Sharing this impact during the consultation helps identify support needs. Not every method claimed to accelerate recovery is suitable or effective. If treatment recommendations conflict, consult the team following your care rather than adding treatments on top of one another. Recording the onset date and changes over time helps compare the course more accurately at later examinations. New neurological symptoms should not wait for routine follow-up.
Frequently asked questions
Is every facial paralysis Bell's palsy?
No. Accompanying arm weakness or difficulty speaking in particular can indicate an emergency.
How can I prepare for the consultation?
Note when your symptoms began and any previous tests or procedures. Bring a list of your medicines and any earlier test results you have. You can share your expectations and questions during the consultation.
Can I stop eye care when facial movements improve a little?
Complete eye closure and the health of its surface require separate assessment. General improvement in the face does not always show that the eye is adequately protected. Clarify with the treating clinician when care can be reduced or stopped. Do not delay assessment if visual changes or eye pain develop.
What questions should I ask when comparing treatment options?
Ask about the main aim of the proposed approach, which symptoms it is expected to help and which problems it may not change. Find out whether monitoring or a different treatment is an option, and what the possible consequences of waiting are in your situation. If the plan includes a procedure, the preparation, follow-up, return to daily life and service to contact if something unexpected happens should be clear. Stating your most important expectation at the start of the consultation makes it easier to compare options against the same goal. It is natural to ask for an unfamiliar medical term to be explained; the decision should be based on the benefits and limitations described to you, as well as the name of the procedure.
