T.M. Joint Ankylosis

Temporomandibular Joint (TMJ) Ankylosis is a condition where the jaw joint becomes stiff or completely fused, restricting mouth opening. It can result from trauma, infection, arthritis, or childhood injury, and severely impacts a person’s ability to speak, eat, and maintain oral hygiene. In children, it can also affect facial growth and symmetry.

What We Do

Our surgical team specializes in the treatment of TMJ ankylosis through precise joint release and reconstruction procedures. Depending on the case, we may use gap arthroplasty, interpositional arthroplasty, or joint reconstruction using costochondral (rib) grafts or artificial implants.

Causes of TMJ Ankylosis

• Injury to the jaw during childhood

• Ear or jaw infections

• Systemic arthritis

• Congenital fusion or birth trauma

• Previous surgery or radiation

Symptoms to Look For

• Inability or difficulty in opening the mouth

• Deviation of the jaw while opening

• Facial asymmetry (especially in children)

• Speech problems

• Difficulty in eating and maintaining oral hygiene

Types of Surgical Treatments

• Gap Arthroplasty – Removing the fused bone to create space

• Interpositional Arthroplasty – Inserting tissue or material between bone surfaces to prevent re-fusion

• Costochondral Grafting – Using rib bone to reconstruct the joint (ideal for growing children)

• TMJ Prosthesis – For adults or complex cases where artificial joint replacement is required

• Coronoidectomy – If muscle fibrosis limits jaw opening even after joint release

Benefits of Surgery

• Restores mouth opening and jaw movement

• Allows normal speech, eating, and oral care

• Improves facial symmetry and growth in children

• Enhances quality of life and confidence

• Prevents long-term dental and skeletal problems

Post-Surgery Rehabilitation

Postoperative jaw physiotherapy is essential to maintain the range of motion and prevent re-ankylosis. Our team provides complete support, including exercises, diet guidance, and follow-ups.

Risks & Considerations

• Recurrence if physiotherapy is not maintained

• Risk of infection, nerve injury, or graft failure

• Multiple surgeries may be needed in severe or relapsed cases
