Arthroplasty for TMJ
Arthroplasty for TMJ disorders is a surgical procedure designed to repair, reshape, or replace parts of the temporomandibular joint (TMJ). It is recommended when other non-invasive treatments or minor procedures like arthrocentesis or arthroscopy fail to relieve symptoms of chronic TMJ dysfunction.
This procedure is particularly effective in treating structural damage in the joint, helping patients regain pain-free movement and normal jaw function.
What is TMJ Arthroplasty?
TMJ Arthroplasty involves open-joint surgery to directly access the TMJ and remove adhesions, reshape joint surfaces, reposition a displaced disc, or reconstruct damaged bone. Depending on the severity, discectomy (removal of the disc) or disc repositioning may also be performed.
This surgery is performed under general anesthesia and is typically recommended in more advanced or complex TMJ cases.
When is Arthroplasty for TMJ Recommended?
Arthroplasty is recommended when:
- The patient suffers from severe jaw pain, stiffness, or locking
- Imaging reveals structural abnormalities like disc perforation, bone damage, or degenerative joint disease
- There is failure of conservative treatments, including splints, medication, and physical therapy
- Previous TMJ surgeries like arthroscopy have not been successful
- The TMJ has developed fibrous adhesions or bone deformities
Benefits of Arthroplasty for TMJ Disorders
- Direct access allows for precise correction of joint issues
- Significant relief from TMJ pain and dysfunction
- Restores jaw movement and bite function
- Prevents further joint deterioration
- Offers a long-term solution for advanced TMJ disorders
Risk Factors of TMJ Arthroplasty
Although TMJ arthroplasty is a well-established procedure, certain risks may be involved, including:
- Temporary or permanent facial nerve injury
- Infection at the surgical site
- Bleeding or hematoma formation
- Scar formation and swelling
- Stiffness or limited jaw movement post-surgery
- Reaction to general anesthesia
- Relapse or recurrence of symptoms in rare cases
What Happens Before the Procedure
- Comprehensive evaluation including medical history, physical examination, and symptom review
- Imaging tests such as MRI, CBCT, or panoramic X-rays to assess joint condition, disc position, and bone degeneration
- Preanesthesia checkup to ensure fitness for general anesthesia
- You may be advised to fast for 6–8 hours before surgery
- Discontinue any blood-thinning medications as per doctor’s instructions
What Happens During the Procedure
- Performed under general anesthesia in an operating room
- A small incision is made near the ear or preauricular region to access the TMJ
- The surgeon may:
- Remove adhesions or scar tissue
- Reposition or remove the disc (discectomy)
- Smooth or reshape bone surfaces
- Place grafts or implants if required
- The incision is then closed with sutures and dressed
Procedure time: Typically 1 to 2 hours
What Happens After the Procedure
- Patients are usually kept under observation for a few hours post-surgery
- Discharge may be the same day or after 24–48 hours, depending on recovery and extent of surgery
- Swelling, bruising, and discomfort near the ear and jaw are common in the first few days
- Sutures are typically removed in 5–7 days, unless dissolvable
Recovery Time
- Initial recovery period: 2–3 weeks
- Full healing and functional recovery: 6–8 weeks
- Most patients return to work or normal routine in about 1–2 weeks depending on the procedure and occupation
- Jaw function and pain relief continue to improve progressively with therapy
Post-Operative Care
- Cold compresses to reduce swelling for the first 48 hours
- Soft or liquid diet for at least 1–2 weeks
- Pain management medications and antibiotics as prescribed
- Avoid excessive jaw movement, yawning, or chewing hard food
- Physiotherapy or guided jaw exercises may begin 1 week post-op, depending on the surgeon’s advice
- Keep the surgical site clean and dry; follow wound care instructions
- Attend all follow-up appointments for evaluation and stitch removal
