Study Notes
Temporomandibular Joint Ankylosis
- Temporomandibular joint (TMJ) ankylosis is a condition where the mandible is fused to the fossa by bony or fibrotic tissue.
- This condition causes difficulty with mastication, speech, oral hygiene, and normal life activities.
- It can be life-threatening when struggling to maintain an airway in an emergency.
- Causes of TMJ ankylosis include trauma (most common), infection, arthritis, previous TMJ surgery, congenital deformities, idiopathic factors, and iatrogenic causes.
- Diagnosis of TMJ ankylosis is typically made by clinical examination and imaging studies, such as plain films, orthopantomograms, computed tomography (CT) scans, MRI, and three-dimensional reconstruction.
Management of TMJ Ankylosis
- The goal of management is to increase mandibular function, correct facial deformity, decrease pain, and prevent reankylosis.
- Surgical modalities used to manage TMJ ankylosis include gap arthroplasty, interpositional arthroplasty, and total joint reconstruction (TJR).
- Different autogenous tissues, such as ear cartilage, temporalis muscle flap, dermis, fat, and bone, have been used for interpositional arthroplasty.
- Alloplastic materials, such as Proplast Teflon and Silastic, have been used, but with high failure rates.
- TJR can be divided into autogenous replacement (costochondral [CCG] and sternoclavicular grafts [SCG]), microvascular reconstruction, or alloplastic replacement.
- CCG has been reported to have unpredictable results in TMJ reconstruction, including reankylosis, resorption, and overgrowth.
- TJR should be considered as the initial treatment modality for management of TMJ ankylosis.
- The use of patient-fitted or stock prostheses shortens operative time, eliminates donor site morbidity, and allows for immediate return to function.
- TJR is also considered in children with failed, overgrown, or ankylosed CCG grafts.
- Autologous fat grafting is a useful adjunct to alloplastic TMJ TJR, potentially reducing heterotopic bone formation around the fossa.
