How TMJ Surgery Works and When It’s Necessary
TMJ Surgery: When to Consider It and Why Conservative Options Come First
Temporomandibular Joint (TMJ) disorders can often be managed through non-surgical treatments such as dental appliances, physical therapy, and other TMJ pain adjuncts. However, surgery may be necessary when these options fail to provide relief.
Many patients are curious about what TMJ surgery entails when surgical intervention is appropriate, and what the recovery process looks like. This article provides an overview of the types of TMJ surgeries, when necessary, and what patients can expect during recovery.
Executive Summary
- 🔧 Types of TMJ surgery: There are several types of TMJ surgeries, including arthrocentesis, arthroscopy, and open-joint surgery, each varying in complexity and recovery time.
- 🦷 When is surgery necessary?: Surgery is typically considered a last resort for patients with severe TMJ dysfunction, including chronic pain, jaw locking, or structural damage that doesn't respond to non-surgical treatments.
- 💊 The recovery process: Recovery from TMJ surgery varies depending on the type of procedure. Most patients experience relief within weeks to months, and physical therapy is often part of the rehabilitation process.
- 🛠️ Non-surgical options first: Before recommending surgery, healthcare providers like Dr. Randi Green usually exhaust non-surgical treatments like physiologic dental appliances, physical therapy, and adjunct treatments.
Insights Based on Numbers
Only about 5-10% of TMJ disorder patients require surgery, as most cases are managed and successfully treated with less invasive treatments.
Types of TMJ Surgery
There are several types of TMJ surgery, each varying in complexity and the issues they address. The type of surgery recommended depends on the severity of the condition and the underlying cause of the TMJ disorder. Here's a breakdown of the most common TMJ surgeries:
Arthrocentesis
Arthrocentesis is the least invasive form of TMJ surgery and is usually performed on an outpatient basis. During this procedure, small needles are inserted into the joint to irrigate and flush out debris or inflammatory byproducts. It is often used to treat TMJ locking cases or remove inflammatory tissue from the joint.
- Recovery: Typically, recovery is quick, with patients experiencing relief within a few days to a week.
Arthroscopy
Arthroscopy is a minimally invasive surgery in which a small camera (arthroscope) is inserted into the TMJ through a small incision. This allows the surgeon to view the joint and perform minor corrective procedures such as removing scar tissue, repositioning the disc, or smoothing joint surfaces.
- Recovery: Recovery usually takes several weeks. Most patients return to normal activities within a few days, but full relief can take a few months.
Open-Joint Surgery (Arthrotomy)
Open-joint surgery is the most invasive TMJ surgery and is typically reserved for severe cases. During this procedure, the surgeon makes an incision in front of the ear to access the TMJ directly, allowing for more extensive repairs, such as disc repositioning, joint replacement, or removal of bone spurs.
- Recovery: Due to the procedure's invasiveness, recovery can take several months, requiring a more extended rehabilitation period.
A study published in the Journal of Oral and Maxillofacial Surgery found that open-joint surgery for temporomandibular joint (TMJ) disorders had a success rate of approximately 55% in improving pain and function.
When is TMJ Surgery Necessary?
Surgery is generally considered a last resort for TMJ disorders and should only be recommended after non-surgical treatments have been exhausted. Most patients can manage their symptoms with less invasive options, but surgery may be necessary in the following cases:
Chronic Pain and Dysfunction
Patients who experience chronic TMJ pain, locking, or difficulty opening and closing their mouth despite trying other treatments may benefit from surgery. TMJ disorders that significantly impact daily life and do not respond to conservative treatments are candidates for surgical intervention.
Structural Damage
In cases where the TMJ has sustained structural damage—such as displaced discs, bone spurs, or severe joint degeneration—surgery may be required to repair or replace the damaged areas.
Jaw Locking or Severe Mobility Issues
If the jaw becomes locked in place or it is extremely difficult to move the joint, surgery may be necessary to restore proper function. This is especially important if a displaced disc or joint misalignment causes the locking.
The Recovery Process
Recovery from TMJ surgery varies depending on the type of procedure performed. Minimally invasive procedures, such as arthrocentesis or arthroscopy, tend to have shorter recovery times, while open-joint surgery requires a more extended rehabilitation period. Regardless of the surgery type, physical therapy is often recommended to restore mobility and function to the jaw after surgery.
What to Expect During Recovery:
- Pain Management: Patients may experience some pain and swelling following surgery, which can be managed with over-the-counter pain relievers or prescribed medications.
- Physical Therapy: Physical therapy is typically part of the recovery process, focusing on improving jaw mobility, reducing stiffness, and preventing scar tissue from forming.
- Dietary Adjustments: Patients are usually advised to eat soft foods for several days or weeks after surgery to avoid putting stress on the jaw.
- Follow-Up Visits: Regular follow-up appointments with the surgeon are necessary to monitor healing and ensure the joint functions properly.
Non-Surgical Options to Try Before Surgery
Before considering surgery, patients are encouraged to explore non-surgical treatments for TMJ disorders. In many cases, these options provide significant relief and can prevent the need for surgical intervention.
Non-Surgical Treatments Include:
- Oral Appliances: Custom-made physiologic orthotics and night appliances reduce teeth grinding and jaw clenching, easing pressure on the TMJ. These appliances are designed using EMG (electromyography) measurements, which analyze muscle activity to ensure the bite is guided into a natural, physiologic position for optimal jaw function.
- Low-Level Red Light Therapy: A gentle, non-invasive treatment that promotes blood flow and reduces inflammation in the TMJ area.
- Ultrasound Therapy: Delivers targeted heat to soothe muscles and improve joint mobility without invasive measures.
- Physical Therapy: Tailored exercises help strengthen and stretch jaw muscles to improve function and alleviate pain.
- Stress Management Techniques: Strategies like meditation, biofeedback, and relaxation exercises help address stress-related jaw tension.
- Medications: Short-term use of anti-inflammatory drugs, muscle relaxants, or pain relievers can help manage acute TMJ symptoms.
- Trigger Point Injections: Targeted injections relax tight muscles and reduce pain in severe cases when other methods aren't enough.

When to Consider TMJ Surgery and Why Conservative Care Comes First
TMJ surgery is a viable treatment option for patients with severe TMJ disorders who do not respond to non-surgical interventions. Several types of TMJ surgeries, from minimally invasive procedures like arthrocentesis to more complex open-joint surgery, can help restore jaw function and alleviate pain.
However, surgery is typically considered a last resort, and patients are encouraged to try conservative treatments first. If you're experiencing persistent TMJ pain or dysfunction and are considering surgery, consult with Dr. Randi Green in Springfield, Missouri, first to discuss the most appropriate options for your condition and avoid a life-altering surgery with conservative, proven care.
