Facial paralysis can appear suddenly or develop after an injury, infection, tumour or surgical procedure. Beyond changing facial movement, it may affect eye closure, speech, eating, drinking and the ability to communicate emotions.
Effective facial paralysis treatment therefore involves much more than trying to restore a smile. Depending on the cause and stage of the condition, patients may need neurological assessment, eye protection, specialised rehabilitation, treatment for involuntary movements or facial reanimation surgery.
In Barcelona, hospitals within the Barcelona International Hospitals network offer coordinated pathways involving otorhinolaryngology, neurology, ophthalmology, rehabilitation and reconstructive surgery. This article explains why that multidisciplinary approach matters and how treatment is adapted to each patient.
What is facial paralysis?
Facial paralysis is the partial or complete loss of movement in the muscles on one or both sides of the face. It occurs when the facial nerve, the brain pathways controlling facial movement or the facial muscles themselves are affected.
What symptoms can facial paralysis cause?
The facial nerve controls many movements that people normally perform without thinking. These include blinking, closing the eye, smiling, raising the eyebrow and controlling the lips while speaking or eating.
Symptoms vary according to the location and severity of the nerve injury. They may include:
- Weakness or loss of movement on one side of the face.
- Difficulty closing the eye completely.
- Drooping of the eyebrow or corner of the mouth.
- Problems speaking, drinking or keeping food inside the mouth.
- Reduced facial expression and smile asymmetry.
- Changes in tearing, taste or sensitivity to sound.
- Facial tightness or involuntary associated movements.
These changes can also have a substantial emotional and social impact. Facial expression plays an important role in identity and non-verbal communication, so patients may feel uncomfortable smiling, speaking in public or participating in social situations.
What causes facial paralysis?
Facial paralysis is not a single disease. Identifying the underlying cause is essential because it influences treatment, prognosis and the urgency of further investigation.
Bell’s palsy
The most common form of sudden peripheral facial paralysis. It is diagnosed after other possible causes have been considered.
Infection
Certain viral or bacterial infections can affect the facial nerve, including Ramsay Hunt syndrome in selected cases.
Trauma or surgery
The facial nerve may be injured after head trauma or during treatment involving the ear, skull base, salivary glands or nearby structures.
Tumours
Tumours affecting the facial nerve, parotid gland, ear or skull base can produce progressive or sudden weakness.
Neurological conditions
A stroke or another disorder affecting the central nervous system can alter the pathways controlling facial movement.
Congenital conditions
Some children are born with facial weakness related to developmental, neurological or muscular conditions.
Why early specialist assessment is important
Sudden facial weakness should be evaluated promptly. A specialist must determine whether it involves the peripheral facial nerve or could be related to a central neurological problem such as a stroke.
The first assessment usually reviews when the weakness began, whether it appeared suddenly or progressively, and whether it is associated with hearing changes, pain, skin lesions, dizziness, limb weakness or other neurological symptoms.
Depending on the clinical findings, investigations may include magnetic resonance imaging, hearing tests, electromyography, neurophysiological studies and a detailed ophthalmological examination.
This assessment helps identify the cause, estimate the degree of nerve damage and establish which treatments are appropriate for the current stage.
When should facial weakness be treated as an emergency?
Seek urgent medical attention when facial weakness is accompanied by difficulty speaking, weakness in an arm or leg, loss of balance, severe headache, confusion or other sudden neurological symptoms. These signs may indicate a stroke or another condition requiring immediate treatment.
Why eye protection is a priority
One of the first concerns in facial paralysis is whether the affected eye can close completely. Reduced blinking and incomplete eyelid closure may leave the cornea exposed and lead to dryness, irritation or more serious damage.
Eye care may involve lubricating drops, ointment, physical protection or temporary measures to help the eyelids close. An ophthalmologist or oculoplastic specialist can assess the cornea and determine whether a procedure is necessary.
In persistent cases, surgery may improve eyelid closure or reposition the eyelids and eyebrow. The appropriate intervention depends on the degree of paralysis, corneal risk and expected nerve recovery.
Facial paralysis rehabilitation
Facial paralysis rehabilitation is not simply a series of generic facial exercises. It is a personalised process designed to improve motor control, symmetry and functional use of the facial muscles.
A specialised therapist evaluates which muscles are active, which movements are limited and whether the patient is developing excessive tension or involuntary contractions.
Treatment may include:
Neuromuscular re-education
Controlled practice to improve coordination and activate facial muscles more selectively.
Mirror exercises
Visual feedback helps patients observe movement and reduce unnecessary muscular effort.
Biofeedback
Real-time information about muscle activity can support more precise motor learning.
Stretching and massage
Selected techniques may help manage stiffness, discomfort and excessive muscle tension.
Speech and oral function
Therapy may address lip control, articulation, drinking and eating when these are affected.
Home programme
Exercises are adapted as recovery progresses and should be performed according to professional guidance.
Performing forceful or repetitive exercises without supervision may reinforce abnormal movement patterns. Rehabilitation should therefore be adjusted to the phase of recovery rather than following the same routine for every patient.
What is facial synkinesis?
As the facial nerve recovers, some patients develop facial synkinesis. This means that an intended facial movement triggers another movement involuntarily. For example, the eye may close when the patient smiles, or the neck may contract while speaking.
Synkinesis may also create tightness, facial asymmetry or difficulty producing a natural expression. Treatment commonly combines neuromuscular retraining with carefully planned neuromodulator injections.
Neuromodulators can reduce excessive activity in selected muscles and improve balance between the affected and unaffected sides. Their effect is temporary, so treatment may be reviewed periodically according to the patient’s progress.
When is facial reanimation surgery considered?
Most patients do not require complex surgery. Facial reanimation surgery is generally reserved for selected cases in which spontaneous nerve recovery is unlikely, the nerve has been severely damaged or persistent paralysis causes significant functional problems.
The choice of operation depends on the cause, duration of paralysis, condition of the facial muscles and availability of functional nerves that can provide a new signal.
Surgical options may include:
- Direct repair or grafting of the damaged facial nerve.
- Nerve transfers from another functioning cranial nerve.
- Cross-face nerve grafting from the unaffected side.
- Muscle transfer to restore active movement or smiling.
- Static procedures to improve facial position and symmetry.
- Eyelid or eyebrow procedures to protect the eye.
These techniques do not all pursue the same objective. Some aim to restore active movement, while others improve resting symmetry, oral control or eye protection. Treatment expectations must be discussed carefully because no procedure can guarantee complete restoration of normal facial nerve function.
Why multidisciplinary care produces a more coherent treatment plan
Facial paralysis can affect several anatomical systems and stages of recovery at the same time. An isolated assessment may address one symptom while overlooking another.
A coordinated team can evaluate the patient from different perspectives and agree on the sequence of treatment. Depending on the case, this may involve:
- Otorhinolaryngology to assess the facial nerve, ear and skull-base region.
- Neurology and neurophysiology to investigate central or peripheral nerve involvement.
- Ophthalmology and oculoplastic surgery to protect the eye and eyelids.
- Rehabilitation and physiotherapy to improve movement and manage synkinesis.
- Speech therapy when articulation, drinking or eating are affected.
- Plastic, maxillofacial or reconstructive surgery for selected reanimation procedures.
- Neurosurgery when the condition involves the facial nerve within the skull or another complex neurological lesion.
This approach is particularly valuable when a patient has already received fragmented opinions or when the condition changes from an initial flaccid phase to recovery with involuntary movements.
Hospital Quirónsalud Barcelona: an integrated Facial Paralysis Unit
Within the Barcelona International Hospitals network, Hospital Quirónsalud Barcelona launched a dedicated Facial Paralysis Unit in March 2026.
The unit was designed to replace fragmented consultations with a coordinated pathway. From the initial visit, patients can be assessed across otorhinolaryngology, ophthalmology and facial rehabilitation, with additional involvement from neurology and neurophysiology when required.
The unit treats peripheral and central facial paralysis, including Bell’s palsy and cases related to infection, trauma, tumours or previous surgery. Its pathway may include advanced diagnostic tests, eye protection, intensive facial rehabilitation, treatment of synkinesis and reconstructive surgery in carefully selected cases.
A coordinated pathway instead of isolated consultations
The Facial Paralysis Unit at Hospital Quirónsalud Barcelona provides an integrated clinical circuit in which specialists share diagnostic information, treatment objectives and follow-up.
This is especially relevant because the patient’s priorities may change over time. Immediate eye protection may be essential at the beginning, while rehabilitation, synkinesis management or reconstructive surgery may become more important later.
The hospital reports that most of the unit’s work focuses on diagnosis, rehabilitation and functional or aesthetic treatment, while complex facial reanimation surgery is reserved for a smaller group of patients.
Facial paralysis care at barnaclínic+ and Hospital Clínic Barcelona
barnaclínic+ provides private access to specialists and services within the Hospital Clínic Barcelona group.
Hospital Clínic Barcelona has a Facial Paralysis Working Group responsible for the comprehensive management of these patients. The group brings together rehabilitation, neurology, physiotherapy, otorhinolaryngology, ophthalmology, plastic surgery, neurosurgery and oral and maxillofacial surgery.
The team reviews patient progress and can coordinate pharmacological treatment, rehabilitation, neuromodulators and surgical reconstruction of the facial nerve or facial position and movement.
This breadth of expertise is valuable in complex cases in which facial paralysis is associated with neurological disease, previous cranial surgery, a skull-base condition or significant eye and facial complications.
What international patients should send for an evaluation
International patients can often begin with a remote review before travelling. Useful documentation may include:
- A medical summary explaining the diagnosis and date of onset.
- Photographs or short videos showing facial movement at rest and during expression.
- Magnetic resonance imaging or other imaging studies.
- Electromyography or nerve-conduction reports.
- Previous surgical and pathology reports.
- Details of rehabilitation, medication or injections already received.
- An ophthalmology report if eye closure is affected.
The specialist team can then determine which disciplines should participate in the evaluation and whether treatment should focus on diagnosis, eye care, rehabilitation, synkinesis or surgical reconstruction.
Patients who have received conflicting recommendations may also consider requesting a second medical opinion in Spain before deciding whether to travel.

Personalised treatment throughout every phase of recovery
Facial paralysis is not only a change in appearance. It can affect vision, communication, eating, emotional expression and social confidence. Treatment must therefore respond to both functional and personal priorities.
A multidisciplinary team can identify the cause, protect the eye, guide facial recovery and determine whether neuromodulators or reconstructive surgery are appropriate. Just as importantly, the plan can evolve as the condition moves through different phases.
Through Hospital Quirónsalud Barcelona and barnaclínic+ / Hospital Clínic Barcelona, international patients can access coordinated expertise for both recent and long-standing facial paralysis within the BIH network.
