Mandibular distraction osteogenesis (DO) has been shown to lead to considerable improvement in obstruction of the posterior airway space in patients with ankylosis of the temporomandibular joint (TMJ), and our objective was to find out if we could confirm these findings. Seventeen patients had spiral computed tomographic (CT) scans before and after DO. After treatment, the overall posterior airway space was enlarged in all three sections of the airway (oropharyngeal, glossopharyngeal, and laryngeal). We then compared rates of change in the airway among the sections using 2-dimensional and 3-dimensional assessments, and found that the rate of change in 3-dimensional assessment of volume was significantly higher than that in the 2-dimensional (62% compared with 34%)...

OBJECTIVES: Patients suffering from osteoarthritis, ankylosis (e.g. post-trauma or tumour) in the temporomandibular joint (TMJ) can present with symptoms such as severely restricted mouth opening, pain or other dynamic restrictions of the mandible. To alleviate the symptoms, a total joint prosthesis can be indicated, such as the Groningen TMJ prosthesis. This was developed as a stock device with a lowered centre of rotation for improved translational and opening capacity. This study aimed to improve the design of the prosthesis, and produce a workflow for a customized Groningen TMJ prosthesis, in order to make it more accurate and predictable...

Reduction malarplasty is one of the most commonly performed cosmetic and plastic surgery in Asian countries. Bony ankylosis of the temporomandibular joint (TMJ) occurs usually as a result of trauma, infection, failed surgeries, and autoimmune diseases. Reduction malarplasty has low incidence of TMJ-related complications. A 33-year-old female patient came with complaint of restricted mouth opening around 18 mm, which was developed immediately after the reduction malarplasty 2 years before. On computed tomography image, bony adhesion and the defect from the surgical drilling were found around right TMJ...

Treatment of patients with bilateral temporomandibular joint (TMJ) ankylosis in a single-stage procedure can be challenging. The implementation of intraoperative navigation has proved beneficial by enabling faster and safer excision by providing real-time identification of vital structures. Navigation also can be used to verify site preparation for custom joint prostheses. This article seeks to establish a protocol, based on the use of intermaxillary fixation screws, to produce accurate and repeatable outcomes for the correction of bilateral TMJ ankylosis with total joint replacement in a single-stage procedure...

OBJECTIVE: Condylar and subcondylar fractures (CSFs) are among the most common mandible fractures. If reduction of these fractures is not carried out correctly, serious complications can result, including infection, damage to temporomandibular joint (TMJ) function, malocclusion, nonunion, malunion, and ankylosis of the TMJ. METHODS: We used a preauricular, mini-incision, open technique (PMIOT) for CSF of the mandible. 66 patients (48 males, 18 females), with a total of 72 CSFs of the mandible, were repaired with PMIOT between 2011 and 2016...

Infection of the temporomandibular joint (TMJ) is a rare pediatric condition resulting from the introduction of pathogens into the joint by hematogenous seeding, local extension, or trauma. Early recognition of the typical signs and symptoms including fever, trismus, preauricular swelling, and TMJ region tenderness are critical in order to initiate further evaluation and prevent feared complications of fibrosis, ankylosis, abnormal facial structure, or persistence of symptoms. Contrast-enhanced computed tomography with ancillary laboratory analysis including erythrocyte sedimentation rate, C-reactive protein, and white blood cell count are beneficial in confirming the suspected diagnosis and monitoring response to therapy...

BACKGROUND: Interpositional arthroplasty (IPA) with temporalis fascia flap has been one of the most frequently performed procedures to treat temporomandibular joint (TMJ) ankylosis. However, recurrence often occurs when the flap lacks bulk or atrophies. Whether to perform IPA or distraction osteogenesis (DO) first has long been a controversial issue when patients presented mandibular dysplasia (MD). This study provided IPA a new graft material sufficient to prevent recurrence, combined the modified protocol of performing DO 6 months after IPA, and evaluated its efficacy in treating TMJ ankylosis patients with MD...

PURPOSE: Mandibular defects involving the condyle represent a complex reconstructive challenge for restoring proper function of the temporomandibular joint (TMJ) because it requires precise bone graft alignment for full restoration of joint function. The use of computer-aided design and manufacturing (CAD/CAM) technology can aid in accurate reconstruction of mandibular condyle defects with a vascularized free fibula flap without the need for additional adjuncts. The purpose of this study was to analyze clinical and functional outcomes after reconstruction of mandibular condyle defects using only a free fibula graft with the help of virtual surgery techniques...

Anne-Frédérique Chouinard, Leonard B Kaban, Zachary S Peacock
Mandibular growth is a complex process that involves the "functional matrix," an interaction of the muscles of mastication, occlusion, and jaw function. Although not a typical growth center, the mandibular condyle has a significant effect on the ultimate size, shape and function of the mandible and secondarily on overall facial form. Acquired temporomandibular joint (TMJ)/condylar abnormalities, such as juvenile idiopathic arthritis, idiopathic condylar resorption, TMJ ankylosis, and condylar hyperplasia, often result in facial deformity and functional deficits...

REVIEW
Cory M Resnick
Indications and considerations for reconstruction of the temporomandibular joint (TMJ) differ between growing and skeletally mature patients. Osteoarthritis, which is the most common cause of TMJ destruction in adults, is comparatively rare in children. The most common indications in young patients are congenital deformities, pathology, ankylosis and progressive resorptive processes. Options for reconstruction include distraction osteogenesis, autologous reconstruction (ie, costochondral graft, free fibula flap), and total alloplastic joint replacement...
