TMJ Ankylosis

Jung-Won Cho, Jung-Hyun Park, Jin-Woo Kim, Sun-Jong Kim
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 is a case report describing sequential management of the left TMJ ankylosis resulted from trauma in early childhood...

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...

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...

Costochondral grafts are used to replace the mandibular condyle in cases of TMJ ankylosis, and are generally viewed as a gold standard for autogenous reconstruction of the mandibular condyle (Güven, 2000; Posnick and Goldstein, 1993 [1,2]). We report a case where overgrowth of costochondral grafts is seen, resulting in asymmetric mandibular growth and dentofacial asymmetry (Posnick and Goldstein, 1993 [2]). A 17 year old male patient presented with an existing costochondral graft performed due to TMJ ankylosis during childhood...

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...

BACKGROUND: The pathogenesis of traumatic TMJ ankylosis remains unclear. This study aimed to verify the role of the lateral pterygoid muscle in the pathogenesis of traumatic temporomandibular joint (TMJ) bony ankylosis. METHODS: Eight 6-month-old male sheep were used in this study. Bilateral TMJ osteotomies were performed to induce sagittal fractures of the mandibular condyle. The lateral one-fourth segment of the disc was removed to establish a model of TMJ bony ankylosis...

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...

OBJECTIVE: Temporomandibular joint ankylosis (TMJa) is a distressing condition, but can be surgically managed by gap or interpositional arthroplasty, with an aim to restore joint function and prevent re-ankylosis. The aim of this paper is to compare two interposition materials used in management of TMJ ankylosis. METHODS: 15 patients with TMJa were randomly allocated to two groups: group A (n = 6), interposition material used was medical-grade silicon elastomer, and group B (n = 9) where the interposition material used was temporalis fascia...

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...

BACKGROUND: Temporomandibular joint (TMJ) ankylosis can be accompanied by various degrees of functional and esthetic problems. Adequate mouth opening, occlusal stability, and harmonious facial form are the main goals of treatment for ankylosis. Distraction osteogenesis has proven to be an excellent treatment for lengthening the ramus-condyle unit. However, various timings for distraction have been suggested, and there is no consensus on selection criteria for performing the procedure in stages or simultaneously with other treatments...

In this prospective, cohort, clinical follow-up study we aimed to investigate the role of conservative gap arthroplasty without interpositional material in managing ankylosis of the temporomandibular joint (TMJ). Thirteen patients (15 joints) with ankylosis who fulfilled the other inclusion criteria were enrolled. The ankylotic mass was excised to create a gap of 7-9mm. No interpositional material was used. Ipsilateral or bilateral masseter reflection, pterygomasseteric sling, and temporalis tendon release plus coronoidectomy were considered if maximum mouth opening failed to reach 35mm...

Temporomandibular joint (TMJ) ankylosis is a pathological condition characterized by articular bony or fibrous tissue fusion. TMJ ankylosis developing during childhood can lead to growth complications because of the loss of mandibular function. Hard and soft autogenous tissue grafting has been used for TMJ reconstruction in the growing patient. However, in cases where autogenous tissue grafts fail either due to unpredictable growth or ankylosis, total alloplastic temporomandibular joint replacement (TMJ TJR) can provide a viable option...
