Temporomandibular joint ankylosis

Min-Ho Woo, Kyu-Ho Yoon, Kwan-Soo Park, Jae-An Park
Bifid mandibular condyle (BMC) is an uncommon morphological variant of the mandibular condyle. Although authors have proposed various etiologies for BMC, no consensus has emerged. In addition, varying findings have been reported regarding the epidemiological parameters of BMC (e.g., prevalence, gender ratio, and age), possibly due to its low incidence. BMC is occasionally associated with symptoms of the temporomandibular joint, such as ankylosis, pain, and trismus; however, it is difficult to detect this condition on conventional radiographs...

Two different surgical methods for the treatment of unilateral traumatic temporomandibular joint (TMJ) ankylosis with a medially displaced residual condyle are described. Eighteen patients with unilateral traumatic TMJ ankylosis and a medially displaced residual condyle, treated between 2008 and 2013, were included in this study. Group A patients (n=10) were treated with an autogenous coronoid process graft (ACPG) for reconstruction of the mandibular condyle, while group B patients (n=8) were treated by lateral arthroplasty (LAP); a temporalis myofascial flap (TMF) was used as interpositional material in both groups...

Acute traumatic temporomandibular joint disc displacement (ATDD) and its sequelae are not familiar for most surgeons. This study is to discuss its sequelae in cases without disc reduction after failed conservative treatment. From 2010 to 2015, 26 patients with 34 joints were included in the study. All patients had at least 3 months conservative treatment. Their maximal incisor opening (MIO) was measured during follow-ups and MRI examination was used to check the condylar bone degeneration. The mean follow-up for conservative treatment after admission was 8...

Traumatic dislocation of the mandibular condyle into the middle cranial fossa is an extremely rare complication of maxillofacial injury. The rarity of this injury has led researchers to propose a set of anatomic features that might explain this injury. These features include a small rounded condylar head, hyper-pneumatization of the temporal bone, a thin roof over the glenoid fossa, and missing posterior teeth. The greatest risk factor for this injury is a blow to the chin when the mouth is open without fracture of the condyle (and therefore no dissipation of the forces)...

Temporomandibular joint (TMJ) Ankylosis is an extremely disabling condition characterized by difficulty or inability to open the mouth resulting in facial asymmetry, malocclusion and dental problems. Surgical excision of the ankylosed mass is the only treatment option available to gain mouth opening. The loss in vertical height of ramus following release of ankylosis is difficult to manage in both unilateral and bilateral TMJ ankylosis. Out of all the methods to restore this height Distraction Osteogenesis (DO) is gaining popularity because of predictable gain in the length without any associated morbidity...

Temporomandibular joint (TMJ) ankylosis is a very desolating structural condition that involves fusion of the mandibular condyle to the base of the skull. It causes difficulty in mastication and breathing. Trauma and Infections are usually responsible. If trauma occurs in young age, it leads to disturbance in growth & facial asymmetry. Treatment of temporomandibular joint (TMJ) ankylosis usually requires adequate excision of the involved ankylotic block (arthroplasty) or interpositional arthroplasty using autogenous or alloplastic materials...

INTRODUCTION: Dislocation of the mandibular condyle into the middle cranial fossa after a trauma is a rare event. The lack of appropriate treatment can lead to ankylosis of the temporomandibular joint (TMJ). We report about a case of TMJ ankylosis following intracranial dislocation of the mandibular condyle through the roof of the articular fossa. CASE REPORT: A 9-year-old patient was referred for a severe limitation of mouth opening that began progressively one year before...

A case of severe mandibular hypomobility due to fibrosis of the left temporalis tendon, combined with ankylosis of the temporomandibular joint, is presented. This case emphasizes the importance of reconstructing the historical timeline to establish a correct diagnosis, ultimately leading to appropriate treatment. The use of minimally invasive surgical techniques and the importance of postoperative rehabilitation are emphasized.

The dental occlusion is the important reference for replacement of the temporomandibular joint. If a patient does not have normal occlusion, few considerations are needed for temporomandibular joint replacement. The custom-made prosthesis, typically fabricated with a stereolithographic model, is probably the optimized solution currently available. However the ready-made stock from Biomet Microfixation System (Jacksonville, FL) is the only available product, which is authorized by the government ministry in South Korea, for replacement of the temporomandibular joint...

The Carey-Finema-Ziter syndrome (CFZS, MIM 254940) is an apparently autosomal recessively inherited disorder consisting of the combination of non-progressive congenital myopathy with Moebius and Pierre Robin sequence, facial anomalies and growth delay. Mental development has been described as normal or delayed. Temporomandibular joint (TMJ) ankylosis is the immobility of the joint caused by ankylotic fusion of the mandible to the cranial base or zygoma. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and oral hygiene...

Congenital temporomandibular joint (TMJ) ankylosis is an uncommon condition that presents itself at or soon after birth in the absence of acquired factors that could have contributed to the ankylosis such as infection and trauma. The experience of managing one such case is reported in light of a review of the literature on this condition. Key management principles include adequate removal of the ankylotic mass, costochondral grafting, and post-op physiotherapy. Most patients reported in the literature with the condition experienced relapse...
