Minimally Invasive Surgery for Joint Disorders
TMJ arthroscopy is a minimally invasive surgical procedure used to diagnose and treat disorders within the temporomandibular joint.
Using a fine camera and specialised instruments, it allows direct visualisation and treatment of the joint—improving function and reducing pain where less invasive measures have been insufficient.
When Arthroscopy Is Considered
Arthroscopy is used for persistent intra-articular TMJ disorders, particularly where symptoms have not responded to conservative treatment or arthrocentesis.
It may be appropriate if you have:
- Ongoing TMJ pain
- Restricted mouth opening
- Joint locking or catching
- Mechanical symptoms within the joint
- Limited response to splints, physiotherapy, medication, or arthrocentesis
It is not used for purely muscle-related (myogenic) pain, which requires a different treatment approach.
How Arthroscopy Works
The TMJ is a small, complex joint where inflammation, adhesions, or disc abnormalities can affect function.
Arthroscopy allows:
- Direct visualisation of the joint space
- Identification of inflammation or structural changes
- Release of adhesions
- Irrigation of the joint
- Targeted treatment of specific abnormalities
This provides both diagnostic clarity and therapeutic intervention within the same procedure.
The Procedure
Arthroscopy is performed under general anaesthetic.
- A small camera (arthroscope) is introduced into the joint through a tiny incision
- Additional instruments may be inserted through separate entry points
- The joint is examined and photographs may be taken to document its condition
The procedure is minimally invasive, with no large incisions.
Recovery
Recovery is generally well tolerated.
- Mild swelling and discomfort are expected initially
- Jaw movement typically improves progressively
- Normal activity can usually be resumed within a short period
Jaw exercises are often recommended to maintain mobility and support recovery.
Outcomes
TMJ arthroscopy can lead to:
- Reduction in joint pain
- Improved mouth opening
- Smoother jaw movement
- Decreased locking or mechanical symptoms
Outcomes depend on the underlying condition and stage of disease, but the procedure is often effective in carefully selected cases.
Risks and Complications
Arthroscopy is generally safe, but potential risks include:
- Temporary swelling or discomfort
- Minor bleeding
- Infection (rare)
- Temporary change in bite or jaw movement
- Injury to surrounding structures (uncommon)
- Incomplete relief of symptoms
Consultation
A detailed consultation allows assessment of your symptoms, examination of jaw function, and identification of the underlying cause.
Book a Consultation
For assessment and treatment of TMJ disorders, including arthroscopy, arrange a consultation to discuss your symptoms and options.
