Why TMJ ankylosis is more common in children?
Conclusion: The prevalence of TMJ ankylosis among children was high; the most common causes were trauma and infection, whereas most of patients came with intracapsular type ankylosis in children leads to facial deformities.
What is TMJ ankylosis?
Temporomandibular joint (TMJ) ankylosis is a pathologic condition where the mandible is fused to the fossa by bony or fibrotic tissues. This interferes with mastication, speech, oral hygiene, and normal life activities, and can be potentially life threatening when struggling to acquire an airway in an emergency.
What is Kaban’s protocol?
Modified Kaban’s protocol (2009) uses autogenous reconstruction of ramus condyle unit (RCU) with costochondral graft (CCG) and transport disc distraction osteogenesis (TDDO) in children with TMJ ankylosis.
What causes TMJ ankylosis?
Temporomandibular ankylosis is most commonly caused by trauma or infection; it may also be associated with certain conditions such as ankylosing spondylitis, rheumatoid arthritis, or psoriasis. The condition is typically treated surgically.
What is Costochondral graft?
Replacement of the condyle with a costochondral graft restores the altered biomechanics after condylectomy or gap-arthroplasty procedures. It avoids the recurrence of ankylosis. In the child, this graft allows harmonious growth of the mandible due to the characteristics of the costochondral cartilage.
Does ankylosing spondylitis show on MRI?
Will ankylosing spondylitis show on MRI? Yes. An MRI scan for AS can provide evidence that a person has it. This imaging technique facilitates the accuracy of diagnosis whether in the early or late stages of developing AS.
What does spondylitis look like?
Symptoms of ankylosing spondylitis The symptoms of AS can vary, but usually involve: back pain and stiffness. pain and swelling in other parts of the body – caused by inflammation of the joints (arthritis) and inflammation where a tendon joins a bone (enthesitis) extreme tiredness (fatigue)
Where is the costochondral joint?
rib
The costochondral joints are formed between the end of the rib and the lateral edge of the costal cartilage. The joint formed is cartilaginous, its perichondrium being continuous with the periosteum of the rib itself. Only slight bending and twisting actions are possible at this joint.
What does it mean to have TMJ ankylosis?
Ankylosis in general means immobility of a joint due to any reason, TMJ ankylosis is immobility of the Mandible due to reasons such as trauma, infection, disease, failed surgery, Rheumatoid arthritis and most common being congenital.
What causes the inflammation of the TMJ joint?
The causes of Inflammation of the TMJ joint include Stills disease or juvenile rheumatoid arthritis, Marie-Strumpell disease (ankylosis spondylitis), psoriatic arthritis, fibrodysplasia ossificans progressiva, and osteoarthritis.
When to expect TMJ ankylosis after disc repair?
Following Arthroplasty : TMJ Ankylosis is seen in patients following Mandibular orthognathic procedures or TMJ arthroplasty. Following disc repair there can be adhesion between the disc and articular eminence. In case of lack of physiotherapy postoperatively can lead to bony ankylosis after discectomy procedure.
How is mandibular deficiency related to ankylosis?
Mandibular deficiency: When there is ankylosis from an early age there will be reduced growth of mandible due to reduced ramal height, micrognathia, birds face appearance is seen in bilateral ankylosis. Antegonial notch is prominent due to the pull of the muscles attached to the mandible.
