What does the graft do?
It creates a pathway for nerve signals from the working side of the face.
Those signals may eventually activate muscles on the affected side or a transferred muscle used to reconstruct a smile.
Facial nerve reconstruction
Cross-Face Nerve Graft
A cross-face nerve graft connects a working facial nerve to the opposite side to help restore movement after facial paralysis.
Is it usually one operation?
It may be part of a staged reconstruction.
Some people need a later muscle transfer. The sequence depends on how long the paralysis has been present and whether the original facial muscles can still respond.
When might movement begin?
Nerve recovery takes months rather than days.
Movement is not immediate or assured. A staged plan can extend beyond a year, and the surgical team monitors progress over time.
01 · Overview
A new pathway for facial movement
A cross-face nerve graft is a facial reanimation procedure, not a hand or wrist operation. A surgeon connects a nerve graft to selected branches of the working facial nerve and routes it across the face toward the paralyzed side.
The graft is commonly taken from the sural nerve in the lower leg. It acts as a bridge through which nerve fibers can grow. The intended destination may be existing facial muscles or a muscle transferred during another operation.
Facial paralysis has several causes, and treatment depends on the cause, duration, and remaining nerve and muscle function. A graft is different from a facelift, which changes tissue position, and from a direct nerve repair, which reconnects injured nerve ends. [1]
- Treatment area
- Face; often with a donor nerve taken from the lower leg
- Main purpose
- Restore a nerve signal pathway for facial movement
- Anesthesia
- Usually general anesthesia
- Treatment course
- May involve multiple operations and facial rehabilitation
Why use the working side of the face?
The working facial nerve carries signals linked to facial expression. Sharing selected signals may allow more coordinated, emotionally driven movement, although the strength and spontaneity of that movement vary.
Why might a muscle transfer also be needed?
After longstanding paralysis, the original muscles may no longer respond adequately to a new nerve supply. A transferred muscle, often a portion of the gracilis muscle from the thigh, can provide a new muscle for smile movement.
02 · Concerns & Goals
What you may want to address
Facial paralysis can change how you smile, communicate, and feel in everyday situations. Your priorities help guide the reconstruction discussion.
An uneven smile
One side of your mouth may move less, making your smile look or feel different.
Limited expression
You may find it harder to show emotion through facial movement, even when your feelings have not changed.
Lip control
Weakness around the mouth may affect drinking, keeping food in the mouth, or speech. A smile-focused graft may not resolve every concern.
A long recovery journey
Waiting for nerve growth and planning possible additional surgery can affect daily life. Understanding the full sequence can help you decide what feels manageable.
03 · Options
How the approaches differ
These are possible ways a cross-face nerve graft may fit into facial reconstruction, not interchangeable choices. Suitability depends on a surgeon’s assessment.
Graft to existing facial muscles
Bring signals to muscles that may still respond.
How it worksThe graft links a working facial nerve branch to nerve branches serving the affected muscles.
May suitSelected patients whose original facial muscles remain suitable for reinnervation.
Main tradeoffThe time needed for nerve growth matters; muscles may lose their ability to respond while waiting.
Staged graft and muscle transfer
Prepare a nerve supply before adding a new smile muscle.
How it worksThe graft is placed first. After assessment of nerve growth, a later operation connects it to a transferred muscle.
May suitSome patients with longstanding paralysis or absent functional smile muscles.
Main tradeoffThis involves more than one operation, additional donor sites, and a longer overall treatment course.
Combined graft and muscle transfer
Perform selected reconstruction steps together.
How it worksIn selected cases, the surgeon places the cross-face nerve graft and transferred muscle during the same operation.
May suitPatients whose anatomy and reconstructive plan support a combined approach.
Main tradeoffCombining steps does not remove the wait for nerve growth or guarantee a useful muscle response.
Graft with an additional nerve supply
Use more than one source of nerve signals.
How it worksA transferred muscle may receive input from both the cross-face graft and another nerve, such as the nerve used for biting.
May suitSelected patients in whom the surgeon aims to combine different sources of movement control.
Main tradeoffConnections and rehabilitation are more complex; spontaneous movement is still uncertain.
Facial paralysis care may combine nerve surgery, muscle surgery, rehabilitation, and separate protection for an eye that does not close fully. [1].
Could the working side become weaker?
Yes. Surgeons select donor branches carefully to preserve useful function, but weakness or altered movement on the working side is a risk worth discussing.
Can this treat paralysis on both sides?
A conventional cross-face graft requires a suitable working facial nerve on the opposite side. When both sides are affected, other nerve sources or reconstruction strategies may be needed.
04 · Results
What may improve and what may remain
Movement develops gradually
The graft does not create an immediate smile.
- Nerve fibers must grow through the graft and reach an appropriate muscle.
- A later muscle transfer may be needed before visible movement can develop.
- Follow-up examinations help assess whether the reconstruction is progressing.
Coordination is a goal, not a promise
The aim is useful movement that fits your expression.
- Smile strength, timing, and spontaneity differ between patients.
- Perfect symmetry at rest or during expression is unlikely.
- Rehabilitation may help you learn to use new movement.
Some concerns need separate treatment
One graft does not restore every facial function.
- Eye closure, brow position, and resting facial support may need their own plan.
- Residual asymmetry or unwanted linked movements may remain.
- Additional procedures may be discussed if recovery is limited.
The cause and extent of facial nerve injury influence recovery and treatment choices; individual results cannot be predicted from the procedure name alone. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery includes healing from surgery and a much longer period of nerve regeneration. Your instructions depend on the donor site and any procedures performed at the same time.
Step 1 · Day of surgery
Treatment day
The team monitors your facial incisions, donor site, comfort, and readiness for discharge or an inpatient stay. Arrange transportation and support according to the planned operation.
Step 2 · First few weeks
Early wound healing
Swelling, bruising, tightness, and donor-site discomfort may occur. Follow-up focuses on wound healing and any concerns with walking or facial movement.
Step 3 · Following months
Waiting for nerve growth
You may not see movement during this stage. The surgeon checks recovery and, if appropriate, considers when to proceed with a planned muscle transfer.
Step 4 · Later months and beyond
Movement and rehabilitation
If useful nerve input develops, specialist rehabilitation may help with control and coordination. A staged reconstruction can continue beyond a year.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Work or schoolPlanning context: Timing depends on discomfort, fatigue, visibility of swelling, and job demands.What affects it: Returning does not mean nerve recovery or complete healing has occurred.
Walking and exercisePlanning context: A leg donor site or concurrent muscle transfer can change activity limits.What affects it: Ask when to increase walking, lifting, and strenuous exercise.
Eating and mouth carePlanning context: Incisions inside the mouth may require temporary changes.What affects it: Get specific guidance about food texture, brushing, and incision care.
Facial exercisesPlanning context: Exercises should match the stage and type of reconstruction.What affects it: Start only the program recommended by your surgeon or facial rehabilitation specialist.
Use your surgical team’s instructions rather than a general recovery schedule. Ask your surgical team whether compresses are appropriate and exactly how to use them.
Before your procedure
- Discuss the cause, onset, and previous treatment of your facial paralysis.
- Bring records of prior facial surgery, imaging, and nerve testing if available.
- Review all medicines and supplements; change them only as directed.
- Discuss nicotine use and the team’s requirements before and after surgery.
- Arrange transportation, help at home, and time away from usual responsibilities.
- Confirm donor sites, possible stages, eye care needs, and follow-up arrangements.
Will the donor area feel different?
Removing a sural nerve usually leaves an area of reduced sensation along the outer foot. This may be lasting. Scar sensitivity or nerve pain can also occur.
How will the surgeon know whether the graft is working?
The surgeon uses examinations and, when helpful, nerve or muscle testing. Before a staged muscle transfer, the team assesses whether the graft appears ready; the assessment cannot guarantee the final result.
06 · Safety
Risks and what your clinician assesses
Temporary swelling, bruising, soreness, tightness, and fatigue can follow surgery. Donor-site numbness may last. New facial movement is not expected immediately.
Bleeding or infection
Bleeding, a collection of blood, or infection can affect facial or donor-site wounds and may require treatment.
Limited or absent movement
The graft may not provide enough nerve input for useful movement, and additional reconstruction may be considered.
Weakness on the working side
Using a donor facial nerve branch can cause weakness or a change in expression on the previously stronger side.
Numbness or nerve pain
The donor site may have lasting sensory loss, uncomfortable sensitivity, or a painful nerve ending.
Scars or unwanted movement
Visible scars, persistent asymmetry, tightness, or unintended linked facial movements may occur.
Anesthesia and combined-surgery risks
Anesthesia can cause complications. If muscle transfer is included, there are additional risks involving its blood supply, healing, and donor site.
Discuss these risks and your individual health history with your surgeon. [1]
What your clinician assesses
- Cause, duration, and pattern of paralysis, including any remaining movement
- Condition of the affected facial muscles and the opposite facial nerve
- Eye closure, mouth function, and priorities for expression
- General health, donor-site suitability, and ability to complete staged care

08 · Questions
Common questions
Is this the same as a facial nerve transfer?
Not exactly. A cross-face nerve graft uses a length of donor nerve to carry signals across the face. Other nerve transfers redirect a nearby functioning nerve, such as the masseteric nerve, to supply facial movement.
Can it restore a spontaneous smile?
That is one reason to consider signals from the opposite facial nerve. Some people develop emotionally driven movement, but spontaneity and strength are not guaranteed.
Will it help my eye close?
A smile-focused cross-face graft should not be assumed to restore eye closure. Incomplete eye closure needs its own assessment and protection plan.
Is it appropriate for recent Bell’s palsy?
Usually, the first priorities are timely evaluation, appropriate medical treatment, and eye protection. Many people recover without reconstruction. Persistent paralysis requires specialist assessment before considering a graft.
