Free extensor digitorum brevis muscle flap in facial paralysis, and the second metatarsophalangeal joint flap is used at the temporomandibular joint reconstruction for a long time. Anatomically, these flaps can be harvested through even the same pedicle flap even on the same regions. Literature is available of their usage along with the use of hand and upper extremity reconstruction. Unlike this example, the authors have used these flaps in maxillofacial region where facial paralysis and temporomandibular joint reconstruction will be performed together...

Mandibular distraction for severe micrognathia in syndromic patients often leads to temporomandibular joint (TMJ) ankylosis, which requires further interventions to regain joint motion. The increased incidence of postdistraction ankylosis is likely related to increased prevalence of preoperative joint pathology in syndromic micrognathic patients. Previous studies have demonstrated that offloading the pressure on the condyle during the distraction process can prevent such TMJ pathology. In this article, the authors describe a successful new method for offloading the condyle to prevent postdistraction ankylosis using an external TMJ offloading device...

Temporomandibular joint (TMJ) ankylosis in growing patients can cause both mouth opening limitation and jaw bone deformity. Lateral arthroplasty (LAP) can restore the medially displaced condyle and thus keep its growth potential. But can the condyle grow as normal is unknown. This study was to evaluate the long-term result after LAP in growing children. Patients from 2010 to 2014 were evaluated. Their CT data within 1 week after operation and during at least 1-year follow-ups were measured by ProPlan CMF 1...

INTRODUCTION AND OBJECTIVES: Management of temporomandibular joint (TMJ) ankylosis is a challenging and rather daunting task owing to complex abnormal anatomy and its sequel to craniofacial structures. Various autogenous grafts and alloplastic materials have been tried with variable success for creation of a near-normal joint. In recent years, neocondyle distraction has added a new dimension to the management of TMJ ankylosis. The aim of this paper is to describe the role of neocondyle distraction in TMJ ankylosis...

A rapidly increasing number of mandibular condylar fractures and some complications related to injuries of temporomandibular elements make this study important. Intra-articular disorders lead to secondary pathological findings such as osteoarthritis, deforming osteoarthrosis, and temporomandibular joint ankylosis that limits mouth opening, mastication, swallowing, breathing, and decreased/lost working capacity or disability. Early diagnosis of intra-articular disorders can prevent from long-lasting functional complications caused by temporomandibular joint injuries...

Nager syndrome, also known as Nager acrofacial dysostosis, was first described by Nager and de Reynier in 1948. The patients commonly present with micrognathia, and a preventive tracheostomy is necessary when there are symptoms of upper airway obstruction. Mandibular distraction osteogenesis is considered as an effective procedure, which not only improves micrognathia but also minimizes the chances of tracheostomy. However, mandibular distraction osteogenesis has some complications such as relapse, teeth injury, infection, and injury of the temporomandibular joints (TMJs)...

INTRODUCTION: Presently, during the surgical treatment of the patients in maxillofacial surgery, one can use various medical implants. Moreover custom made implants are being used. Replacements may be fitted to the structure and shape of the human skull owing to CAD/CAM (custom aided design/manufacture) called customized implants. This study was aimed to report for the first time clinical material from which custom implants, using two different techniques, were manufactured to reconstruct the temporomandibular joint (TMJ)...

Approaches providing the positioning of human amniotic membrane (HAM) within the intra-articular space of arthritic TMJs have never been investigated. This contrasts with the increasing amount of evidence suggesting the potential positive effects of HAM on a number of surgical conditions, even included the interpositional arthroplasty for TMJ ankylosis. Thus, the possible usefulness of HAM to restore joint functions in severely damaged TMJs could be hypothesized. Based on these premises, the clinical research question "Is human amniotic membrane positioning effective to reduce symptoms and restore jaw function in patients with severe inflammatory-degenerative disorders of the temporomandibular joint?" has been addressed by performing a systematic review of the literature...

Numerous oral and maxillofacial procedures in dentate patients begin with the fixation of occlusions. While several techniques exist to perform mandibulo-maxillary fixation, many surgeons use arch bars in common practice. In cases of severe craniofacial traumas or jaw malformations, such as temporomandibular joint ankylosis, it may be impossible to use rigid arch bars. This technical note reports on the development of a technique to produce pre-shaped rigid arch bars using 3D printing technology. We take the case of a patient who presents Le Fort 1, Le Fort 2 and Le Fort 3 fractures as well as a central palatine disjunction, an angular mandibular fracture and bilateral zygomatic fractures...

BACKGROUND: Temporomandibular joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore, and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of reankylosis. Costochondral graft (CCG) is a common treatment modality for TMJ ankylosis. One of disadvantages of CCG is unpredictability of growth pattern and risk of overgrowth...
