What it is
Arthrocentesis or TMJ Arthroscopy addresses mechanical TMJ problems that do not respond to conservative care or involve structural disease. The aim is to reduce pain, improve opening, and restore function for eating and speech.
What happens when it occurs
The procedure reduces mechanical irritation or replaces damaged structures. Early protection and graded motion prevent stiffness, allowing tissues to heal.
Common indications and pre‑operative factors
- Inflamed joint not responding to care
- Adhesions or disc issues are causing restriction
- Recurrent painful clicking or locking
Who is most affected
Adults with persistent TMD. Younger patients may require procedures after trauma or severe locking.
Typical symptoms before surgery
- Persistent joint pain with chewing
- Clicking, locking, or restricted opening
- Tooth wear in bruxism and bite change in some cases
When to seek care
When pain and restriction persist despite a structured conservative programme. Urgent care for infection or trauma.
How we diagnose
History, range of motion, and deviation, joint sounds, dental and cervical assessment, and MRI or CT scans to confirm pathology and plan treatment.
Management
- Protected range with controlled midline opening
- Soft diet initially, with graded return to normal foods
- Scar and joint mobility within comfort
- Neck and scapular endurance and posture drills
- Dental collaboration for bite and splint, where needed
Rehabilitation milestones
Phase 1 days 0–7: pain control, protected range, soft diet.
Phase 2 weeks 1–4: expand opening and lateral glide, add endurance.
Phase 3 weeks 4–12: normal diet and voice load, criteria-based return to work.
Readiness to progress
- Wound healed and infection excluded
- Opening range improving toward functional targets
- Chewing is tolerated without a next-day flare
Long-term care
- Brief weekly control and endurance work
- Dental reviews for bite support
- Sleep and stress strategies for bruxism where relevant
Australia snapshot
- Procedures performed in specialist maxillofacial and ENT centres
- Most patients return to a normal diet by stages
- Rehabilitation improves outcomes and reduces recurrence
Latest insights
Protect early motion, then expand range and endurance.
Chewing tolerance improves in small, repeatable steps.
