Does TMJ surgery change your appearance?

"Will my face look different after surgery?" It is a question many of my patients ask quietly, sometimes almost apologetically, as if it were a vain concern. It isn't. The jaw joint sits right in front of the ear, and the jaw shapes the lower face, so it is completely natural to wonder whether TMJ surgery will change how you look. The honest answer depends on which type of TMJ surgery you are having and why. Let me explain.
Quick Answer
- Minimally invasive procedures (arthrocentesis and arthroscopy) do not change the shape of your face. At most, they leave one or two tiny marks in front of the ear that usually fade to be barely visible.
- Open joint surgery leaves a fine scar, usually hidden in the natural crease in front of the ear, and does not usually change your facial shape.
- Joint replacement or reconstruction may change your appearance, but in patients with jaw deformity, asymmetry, or a receding chin, this change is often an intended improvement.
- Almost every patient has temporary swelling after surgery, which can make the face look different for a few days to a few weeks.
Appearance Changes Depend on the Type of TMJ Surgery
"TMJ surgery" is not one operation. It covers a range of procedures, from a simple joint wash to complete joint replacement. Here is how each one affects your appearance:
| Procedure | What is done | Effect on appearance |
|---|---|---|
| Arthrocentesis | The joint is washed out using fine needles. | No change in facial shape. Needle marks usually disappear completely. |
| Arthroscopy | A thin camera and instruments are used through 1–2 tiny punctures. | No change in facial shape. Tiny marks in front of the ear that usually fade to a dot or fine line. |
| Open joint surgery (arthroplasty, disc repair or removal) | The joint is opened through an incision in front of the ear. | Usually no change in facial shape. A fine scar, usually well hidden in the skin crease in front of the ear and sometimes into the hairline. |
| Total joint replacement / reconstruction | The damaged joint is replaced with a custom prosthesis or reconstructed with the patient's own tissue. | Scars in front of the ear and usually under or behind the angle of the jaw. May change jaw position and facial profile, often improving balance and symmetry. |
Arthrocentesis and Arthroscopy: Your Face Stays the Same
For most patients with TMJ pain, clicking, or locking, I start with the least invasive treatment that can solve the problem. Arthrocentesis and arthroscopy work inside the joint. They do not move bones, change the jaw's position, or alter your facial structure.
The only visible signs are one or two tiny puncture marks just in front of the ear. I place these along the natural skin fold wherever possible. They look pink for the first few weeks, then fade steadily, and for most patients are very hard to find by 3–6 months.
Open Joint Surgery: A Hidden Scar
When the joint needs more extensive repair, an open procedure may be needed. The incision is placed in the natural crease where the ear meets the face, and may extend slightly into the hairline above. This crease hides the scar very well. Once fully healed, most people will not notice it unless they are specifically looking for it.
Open joint surgery is done to repair the joint, not to change the shape of the face, so the overall contour of your face usually stays the same.
Joint Replacement: When a Change Is the Goal
Total joint replacement or reconstruction is reserved for severely damaged joints, for example after advanced arthritis, condylar resorption, ankylosis (a joint that has fused), trauma, or multiple failed surgeries. Many of these patients already have a visible change in their face caused by the joint disease itself, such as:
- A receding chin or "small jaw" appearance
- Facial asymmetry, where the jaw or chin is shifted to one side
- An open bite, where the front teeth do not meet
- Difficulty closing the lips comfortably
In these cases, reconstructing the joint, sometimes together with corrective jaw surgery (orthognathic surgery), can restore the height and position of the jaw. The result is often a more balanced, symmetrical face and a better profile, along with improved bite, function, and in some cases breathing during sleep.
Joint replacement usually involves an incision in front of the ear and another under or behind the angle of the jaw. These are planned to sit in natural creases or shadowed areas and usually become fine lines over time.
For patients whose jaw has been changed by disease, TMJ reconstruction is often not about changing who they are — it is about giving back the face and function that the condition had taken away.
Temporary Changes After Any TMJ Surgery
Even when the long-term appearance does not change, there are short-term changes that are normal during healing:
Swelling
Swelling in front of the ear and along the cheek is common. After arthroscopy, it usually settles within a few days. After open surgery or joint replacement, it can take a few weeks to settle fully, and the last bit of subtle swelling may take a few months.
Bruising
Some patients develop mild bruising around the ear or jaw, which fades within 1–2 weeks.
Change in Bite
After arthroscopy, the bite on the treated side may feel slightly off for a few days. After joint replacement, the bite may be intentionally changed as part of the treatment plan.
Numbness Around the Ear
The skin in front of the ear or the earlobe may feel numb after open surgery. This usually improves over weeks to months.
Temporary Facial Weakness (Uncommon)
The facial nerve, which moves the forehead and eyelid, runs close to the joint. In open surgery, and rarely in arthroscopy, it can be stretched, causing temporary weakness in raising the eyebrow or closing the eye. In most cases this recovers over weeks to months. Careful surgical technique keeps this risk low, and I discuss it openly with every patient before surgery.
How I Minimise Any Effect on Your Appearance
- Choosing the least invasive option that can effectively treat your joint
- Placing incisions in natural creases and the hairline so scars are well hidden
- Careful handling of tissues and nerves to reduce swelling and protect facial movement
- Fine, layered closure of incisions for a neat scar
- Detailed planning with scans and, where needed, 3D models for joint replacement, so changes in jaw position are predictable
- Clear aftercare instructions, including sun protection and scar care, which matters especially in Indian skin, where dark marks are common
What You Can Do to Help
- Use cold compresses for the first 48 hours, then warm compresses to help swelling settle.
- Sleep with your head slightly raised for the first few nights.
- Do not pick at scabs, and start silicone gel on the healed wound only when advised.
- Protect the scar with sunscreen (SPF 30 or higher) daily for at least 6 months.
- Avoid smoking, which slows healing and can worsen scarring.
- Keep your follow-up appointments so any concern is addressed early.
Contact Your Surgeon Promptly If You Notice:
- Swelling that is increasing instead of reducing after the first few days
- Redness, warmth, pus, or fever
- New difficulty closing your eye or raising your eyebrow
- A sudden change in your bite or inability to close your teeth together
- A scar that becomes thick, raised, or grows beyond the wound edges
My Message to You
For the majority of TMJ patients, surgery does not change how they look. Procedures like arthrocentesis and arthroscopy leave the face exactly as it was, apart from tiny marks that fade with time. Open surgery leaves a well-hidden scar. And for patients with severe joint disease who have already seen their face change, reconstruction can often restore balance and symmetry.
If appearance is a concern for you, please tell me during your consultation. I will explain exactly which procedure you need, where any incisions will be, and what you can expect to see during healing and afterwards, so there are no surprises.
Frequently Asked Questions
Does TMJ surgery change your face shape?
Arthrocentesis, arthroscopy, and most open joint surgeries do not change the shape of your face. Total joint replacement or reconstruction can change jaw position and facial profile, usually as a planned improvement in patients with jaw deformity or asymmetry.
Will TMJ surgery leave a scar on my face?
Arthroscopy leaves only one or two tiny marks that usually fade to be barely visible. Open surgery leaves a fine scar hidden in the crease in front of the ear. Joint replacement usually involves an additional incision under or behind the angle of the jaw, which also fades to a fine line over time.
How long does facial swelling last after TMJ surgery?
After arthroscopy, swelling usually settles within a few days. After open surgery or joint replacement, most swelling goes down in a few weeks, with subtle swelling sometimes taking a few months to disappear completely.
Can TMJ surgery fix facial asymmetry?
When asymmetry is caused by joint disease, such as condylar resorption, ankylosis, or abnormal joint growth, joint reconstruction, sometimes combined with corrective jaw surgery, can significantly improve facial symmetry.
Can TMJ surgery affect facial movement?
The facial nerve lies close to the joint, so temporary weakness of the forehead or eyelid is a known but uncommon risk, mainly with open surgery. In most cases it recovers over weeks to months. Your surgeon should discuss this with you before the procedure.
