Trauma is the predominant causal factor for temporomandibular joint (TMJ) ankylosis. However, the relationship between condylar fracture and TMJ ankylosis is complicated. It is believed that post-traumatic TMJ ankylosis arises from TMJ intracapsular changes, including damaged cartilage, displaced or disrupted discs, haematoma formation and subsequent fibrosis and calcification in the joint. In ...

BACKGROUND Temporomandibular joint (TMJ) ankylosis in children often leads to facial deformity, functional deficit, and negative influence of the psychosocial development, which worsens with growth. The treatment of TMJ ankylosis in the pediatric patient is much more challenging than in adults because of a high incidence of recurrence and unfavorable growth of the mandible. CASE REPORT This i...

OBJECTIVE The purpose of the study was to preliminarily explore the differential expressions of a series of genes regulating bone formation in temporomandibular joint (TMJ) fibrous ankylosis, bony ankylosis and condylar fracture healing. METHODS The cDNA from either the bony ankylosed callus or fracture callus of the 6 sheep, as described in the part I, were both used in the study. The differ...

Temporomandibular Joint (TMJ) ankylosis is the pathological osseous or fibrous fusion of the condyle of the mandible with the mandibular fossa of temporal bone. The etiology of TMJ ankylosis includes previous trauma, infection, arthritis and previous TMJ surgery. The Temporomandibular Joint (TMJ) ankylosis in children is rare and the exact causes remain unclear. Trauma is well known as the most...

The aim of this retrospective clinical study is to present the clinical experience of using dermis-fat interpositional grafts in the surgical management of temporomandibular joint (TMJ) ankylosis in adult patients. Eleven adult patients who presented with ankylosis of the TMJ were identified and included in the study. All patients underwent a TMJ gap arthroplasty which involved the removal of a...

PURPOSE Two common treatments of temporomandibular joint ankylosis are gap arthroplasty and ankylosis resection and reconstruction of the ramus-condyle unit with a costochondral graft. The purpose of the present study was to answer the following clinical question: "Among patients with temporomandibular joint ankylosis, do those patients who undergo gap arthroplasty, compared with those who unde...

Targeted therapies that neutralize tumour necrosis factor are often able to control the signs and symptoms of spondyloarthritis. However, recent animal model data and clinical observations indicate that control of inflammation may not be sufficient to impede disease progression toward ankylosis in these patients. Bone morphogenetic proteins and WNTs (wingless-type like) are likely to play an im...

conclusions this study shows that simultaneous arch osteotomy and coronoidectomy may be an appropriate treatment procedure for zygomatico-coronoid interference. introduction zygomatico-coronoid interference is a rare type of mandibular extracapsular ankylosis. there is a lack of information on the treatment of these cases in the literature. condylectomy and coronoidectomy are not always the bes...

Temporomandibular joint (TMJ) ankylosis is a disabling condition of the masticatory system and is most commonly due to trauma, infections, and some systemic diseases. Hypomobility affects the surrounding structures as well as the joint itself. Ankylosis arising in early childhood usually leads to facial asymmetry. Ankylosis in children usually occurs from an intracapsular compression fracture o...

The American Academy of Orofacial Pain (AAOP) defines ankylosis of the temporomandibular joint (TMJ) as a restriction of movements due to intracapsular fibrous adhesions, fibrous changes in capsular ligaments (fibrous-ankylosis) and osseous mass formation resulting in the fusion of the articular components (osseous-ankylosis). The clinical features of the fibrous-ankylosis are severely limited ...
