Background: Temporomandibular joint ankylosis is one of the most distressing clinical condition resulting in loss of jaw function and impairment of growth. Ankylosis is a greek word meaning "Stiff Joint". It is observed that in humans the Sternoclavicular joint and Temporomandibular joint are similar morphologically and histologically as they are the only two synovial joints covered with fibrocartilage. This similarity of the joints have encouraged the surgeons to use SCG as an alternative to costochondral grafts...

Traumatic intracranial intrusions of the mandibular condyle are a rare injury pattern that carries significant morbid outcomes due to potential for neurological, otological, temporomandibular joint damage, or joint ankylosis. Treatment modalities involve either closed reduction, open approaches via transcranial or subtemporal approaches, or delayed total joint replacement. This paper presents a clinical report of a traumatic intracranial intrusion of the mandibular condyle treated with an endoscopically assisted preauricular approach to reconstruct the middle cranial fossa and temporomandibular articular disc...

Introduction: Temperomandibular joint (TMJ) is subjected to many disorders commonly called Temperomandibular disorders (TMDs); such as TMJ hypermobility, ankylosis, internal derangement, degenerative joint disease. Internal derangement is characterized by abnormal relationship of articular disc to the condyle and disc to fossa. In past many non-invasive conservative treatment modalities were tried out for its treatment which are joint unloading, use of anti-inflammatory agents, physiotherapy etc...

Temporomandibular joint (TMJ) ankylosis is an extremely handicapping condition characterized by a permanent restriction in the ability to open the mouth, and it is mainly caused by traumatic and infectious events. It rarely occurs as a complication following orthognathic surgery. The treatment goals are the restoration of viable mandibular function and, in growing pediatric patients, symmetrical mandibular development. We are reporting here the unusual case of a bilateral bony TMJ ankylosis in a patient who underwent a bilateral sagittal split osteotomy of the mandible for correction of a mandibular deficiency...

PURPOSE: Disorders of the temporomandibular joint (TMJ) occur frequently, with a prevalence of 15 to 18%. Total joint replacement (TJR) surgery is indicated for severe joint damage associated with impaired function, pain, or occlusal change for which other treatments have been unsuccessful. The aim of this study was to assess changes in pain and range of motion (ROM), as well as postoperative complications and comorbidities, in patients receiving TJR surgery at Massachusetts General Hospital (MGH)...

INTRODUCTION: In severe TMJ ankylosis cases, the lack of growth of the mandible creates an anatomically narrow airway with a reduced pharyngeal airway space [PAS] which predisposes these patients towards obstructive apnoea [OSA]. There is evidence in the literature that such patients experience severe discomfort during physiotherapy if such airway abnormalities are not corrected prior to ankylosis release. This eventually leads to non-compliance towards physiotherapy and increases the risk of re-ankylosis...

Introduction: The temporomandibular joint (TMJ) is a complex joint, and it allows bilateral synchronous rotatory and translatory movements. TMJ reconstruction has evolved as an important step in the management of conditions affecting the TMJ like ankylosis, traumatic injuries and congenital deformities. Distraction osteogenesis (DO) is a biological process of forming new bone and adjacent soft tissues by gradual and controlled traction applied on osteotomized bone segments. Case report: Here is a case report of bilateral TMJ ankylosis which was managed effectively by resection of ankylotic mass and reconstruction of TMJ by transport distraction osteogenesis with preoperative vector planning using a 3D printed model...

Rheumatic diseases (RD) of the temporomandibular joints (TMJs) are increasingly frequent affections and unfortunately often confused with "classic" manducatory dysfunctions (disk dislocation, myofascial pain syndroms). Their diagnosis is mandatory, given the major subsequent craniofacial disorders, which may occur (mandibular condylar hypoplasia, facial hyperdivergence, remodelling of the condylar unit, ankylosis), although the clinical implementation remains unspecific. The delayed diagnosis may be explained by the embryologic, anatomical and physiological characteristics of this joint...

This case report presents a 16-year-old boy with bilateral temporomandibular joint (TMJ) bony ankylosis due to trauma. The patient had undergone several unsuccessful therapeutic surgeries and was experiencing reduced mouth opening, difficulty in eating and speaking, poor oral hygiene, snoring, and depression. Bilateral gap arthroplasty and distraction osteogenesis (DO) were performed. After the surgery, we were able to move the osteodistractors forward and prevent the upward and backward movement of the proximal mandibular segment with the use of our custom-made Sh-device, which allowed bone growth and soft-tissue matching...

Temporomandibular joint (TMJ) ankylosis is fusion or a bony union of the head of the condyle and the glenoid fossa by bony or fibrotic tissues. Due to the immobility of the TMJ, all mandibular movements get affected. Treatment goals are to allow nearly normal TMJ movements, restore symmetry of the face and occlusion, and promote growth and correction of deformity in children. The surgical techniques used to treat TMJ ankylosis are a gap or interpositional arthroplasty, joint reconstruction, and distraction osteogenesis...

Facial paralysis can be a devastating consequence resulting from blunt and penetrating trauma to the head and neck, as well as surgical injury, either accidental or due to involvement by tumor. In addition, the etiology can be attributed to a variety of other causes, ranging from infectious to metabolic, and is frequently idiopathic in nature. The incidence of facial nerve injury during temporomandibular joint (TMJ) surgeries varies among surgeons. There are many factors that could contribute to the injury of the temporal and zygomatic branches of the facial nerve...
