Can a facelift cause nerve damage? The facial nerve risk explained honestly
Yes, a facelift can cause nerve damage. It is the complication I take most seriously, it is the one patients are most frightened of, and it is the one that is discussed least honestly in marketing material. So let me answer the question directly before going into detail.
Facelift nerve damage falls into two very different categories. The first is injury to sensory nerves, which supply feeling to the skin of the cheek, ear and neck. Some degree of temporary numbness after a facelift is not a complication; it is expected, and it recovers over weeks to months in the great majority of patients. The second is injury to the facial nerve, which controls the muscles of expression. This is the injury that matters. Published series generally report temporary facial nerve weakness after a facelift in the low single-digit percent range, and permanent weakness at well under one percent. Most facial nerve injuries during a facelift are a stretch or bruise of the nerve rather than a cut, and they recover.
In this article I explain where the facial nerve runs, why the deep plane facelift is often accused of being riskier for it, what actually protects the nerve, and what happens if an injury does occur.
What the facial nerve does and where it runs
The facial nerve leaves the skull just behind the ear, passes through the parotid gland (the large salivary gland in front of the ear), and then divides into five main branches that fan out across the face. Each branch controls a different group of muscles.
The temporal (frontal) branch lifts the eyebrow and wrinkles the forehead.
The zygomatic branch closes the eye.
The buccal branch moves the cheek and upper lip, and helps the smile.
The marginal mandibular branch pulls the lower lip down and out.
The cervical branch tightens the platysma, the thin sheet of muscle in the neck.
The branches that are most exposed during a facelift are the temporal branch, because it crosses the cheekbone in a very superficial plane, and the marginal mandibular branch, because it runs along the jawline close to where jowls are corrected. The buccal branches lie under the SMAS in the mid-cheek and are the ones most relevant to a deep plane dissection.
Sensory nerve changes: expected, not a complication
Almost every facelift patient has numbness of the cheek, in front of and below the ear, and sometimes the neck. Small sensory nerve fibres in the skin are unavoidably divided when the skin is lifted. They regrow slowly, and sensation returns over roughly three to twelve months. Tingling, itching and odd electric sensations along the way are signs of recovery, not damage.
The one named sensory nerve at risk is the great auricular nerve, which supplies feeling to the lower ear and the skin behind it. Numbness of the earlobe after a facelift is usually this nerve. Most cases recover; in a small number the earlobe stays numb. It is more common than facial nerve injury, though far less serious.
Facelift facial nerve injury: how it actually happens
A facial nerve branch can be harmed in a few ways during surgery.
The most common is traction, meaning the nerve is stretched when the tissue around it is lifted and repositioned. The nerve is not cut, but its function is disrupted, and it recovers over weeks to months as the nerve fibres settle.
The second is thermal injury from the electrical cautery used to control bleeding. A nerve close to a cautery tip can be stunned or damaged.
The third is local anaesthetic. The solution injected before surgery sometimes temporarily blocks a branch; a patient who cannot lift one eyebrow in the recovery room usually has an anaesthetic effect that wears off within hours.
The rarest and most serious is transection, where a branch is actually divided. This is the injury that can produce permanent weakness. It is uncommon in experienced hands because the surgeon knows where the branches are expected to lie and works in planes that protect them.
Deep plane facelift nerve risk: is it really higher?
Australian and New Zealand patients often ask this after reading online that the deep plane facelift is "closer to the nerve" and therefore more dangerous. The concern is understandable. In a deep plane facelift, the surgeon releases the SMAS (the fibrous and muscular layer under the skin) from the deeper structures and lifts it as a single unit with the skin attached. The facial nerve branches run just below this plane. So, yes, the dissection is nearer the nerve than in a facelift that simply tightens the SMAS with sutures from above.
But there is a counter-argument that I find convincing, and it is why I perform the deep plane technique as my standard operation. The facial nerve branches to the cheek lie within a layer of loose fatty tissue below the SMAS, and they are protected by a series of ligaments and fascial layers. A surgeon who understands this anatomy dissects in a defined space, sees the structures directly and releases the ligaments under vision. Techniques that pull firmly on the SMAS from above, without releasing anything, transmit traction onto the nerves blindly.
In other words, the deep plane facelift nerve risk depends far more on the training and experience of the surgeon than on the name of the operation. In experienced hands, published series of deep plane facelifts have not shown consistently higher permanent nerve injury rates than other techniques, and I would not offer the operation if I believed otherwise. I have written about what the technique demands of a surgeon in facelift techniques compared.
What a facelift nerve injury looks like
If a facial nerve branch is affected, the pattern depends on which one.
Branch affectedWhat you would noticeTypical courseTemporal (frontal)One eyebrow will not lift, forehead smooth on that sideUsually recovers over weeks to monthsZygomaticDifficulty closing the eye fullyUncommon; needs eye protection while recoveringBuccalWeak smile on one side, cheek does not moveOften recovers; cross-connections between branches helpMarginal mandibularLower lip does not pull down evenly, asymmetric smileUsually recovers; can take monthsCervicalSubtle weakness of neck muscle, lower lip asymmetryOften mistaken for marginal mandibular injury
One important point: an asymmetric smile in the first two weeks is very often swelling, not a nerve injury. I ask patients not to conclude anything about nerve function until the early swelling has settled, and I assess it myself at every review.
How often does facelift nerve damage happen?
The figures that appear consistently across published facelift series are these: temporary facial nerve weakness in a low single-digit percentage of patients, permanent weakness at a small fraction of one percent, and great auricular nerve numbness more often than either, most of it recovering. These are averages. Your individual risk depends on your surgeon's experience with the specific operation, your anatomy, previous facial surgery (scar tissue distorts the normal planes), and how extensive the procedure is.
How I reduce the risk in my own practice
I cannot make the risk zero. What I can do is remove the avoidable contributors.
I dissect in known anatomical planes and identify the landmarks that tell me where each branch lies, rather than relying on depth alone. I use cautery sparingly near the danger zones and prefer to control bleeding with pressure and fine ties where the nerve is close. I do not use excessive traction on the SMAS flap. I operate under conditions where the patient is still and comfortable, which is one of the reasons I discuss the choice of anaesthesia so carefully; a patient who moves suddenly during a deep dissection is a risk to themselves.
I document and photograph any pre-existing asymmetry or previous Bell's palsy before surgery. And I say no to some patients: someone with multiple previous facelifts, heavy scarring and distorted anatomy may be safer with a more limited operation, or none at all.
What happens if a nerve injury occurs
If I see facial weakness that persists after the early swelling settles, my approach is patient and methodical.
The first step is observation, because most injuries are traction or thermal and recover on their own. The second is eye protection if eye closure is affected, using lubricant drops and taping the eye at night. The third, for a persistent eyebrow droop, may be a small dose of botulinum toxin on the opposite side to balance the brow while the injured side recovers. Nerve recovery is measured in months, and I follow these patients closely by video after they return to Australia or New Zealand.
Facelift risks in context
Nerve damage is one of several facelift risks. A haematoma (a collection of blood under the skin) is the most common early complication and is the reason blood pressure control and stopping blood-thinning medications matter; I cover this in your medications and cosmetic surgery. Infection is uncommon in the face. Skin loss behind the ear is a risk mainly in smokers. Unsatisfactory or unnatural results are, honestly, more common than any medical complication.
For Australians and New Zealanders coming to Bangkok, there is one more practical point. Travel insurance policies generally exclude elective cosmetic surgery abroad and complications arising from it. If a nerve injury or any other complication needs follow-up, that follow-up is between you and your surgeon, and you should ask any surgeon you consider how they handle complications after you have flown home. I have covered what to ask in hospital or clinic: what to ask before cosmetic surgery overseas.
Frequently asked questions
Is numbness after a facelift the same as nerve damage?
No. Numbness of the cheek and around the ear is expected after a facelift because small sensory nerves in the skin are divided when it is lifted. It usually recovers over three to twelve months. Nerve damage in the sense that worries patients refers to the facial nerve, which controls movement, and that is a separate and much less common event.
How common is permanent facelift nerve damage?
Published facelift series generally report permanent facial nerve weakness at well under one percent, with temporary weakness in the low single-digit percent range. Most temporary cases are caused by stretching or bruising of a nerve branch and recover over weeks to months.
Does a deep plane facelift have a higher nerve risk?
The dissection is closer to the facial nerve branches than in a simple SMAS tightening, but the nerve is seen and protected rather than pulled on blindly. In experienced hands, published results have not shown a consistently higher permanent injury rate. The surgeon's training in the technique matters more than the technique's name.
What are the signs of facial nerve injury after a facelift?
Inability to lift one eyebrow, difficulty closing one eye, a crooked smile, or a lower lip that does not move down evenly on one side. In the first two weeks these are very often caused by swelling rather than nerve injury, so they need to be assessed once early swelling has settled.
Can facelift nerve damage be repaired?
Most injuries recover without any treatment. If a branch has been cut, direct repair is sometimes possible if recognised at the time. For long-standing weakness, procedures exist to improve symmetry, but they are rarely needed after a facelift.
