BACKGROUND Satisfactory surgical correction of temporomandibular joint ankylosis (TMA) is limited by a high recurrence rate, particularly in patients who underwent surgery without use of interpositional material. The present study describes our experience of Interpositional Gap Arthroplasty in patients presenting with primary or recurrent TMA. METHODS The study was conducted on 12 patients pr...

BACKGROUND The most common complication of surgery for the release of temporomandibular joint (TMJ) ankylosis is relapse of the ankylosis. To prevent re-ankylosis, a variety of interpositional materials have been used. AIM The aim was to compare the surgical outcome of oral mucoperiosteal flap, not hitherto used as interpositional material, with pterygo-masseteric muscles flap after surgical ...

UNLABELLED Objective : Biomodification of the root surface plays a major role in periodontal wound healing. Root surface modification with bone morphogenetic protein (BMP) stimulates bone and cementum-like tissue formation; however, severe ankylosis is simultaneously observed. Bio-safe collagen hydrogel scaffolds may therefore be useful for supplying periodontal ligament cells and preventing an...

Objective: To evaluate the effect of the sequential treatment of temporomandibular joint ankylosis with secondary deformities by distraction osteogenesis Methods: We retrospected 40 patients with temporomandibular joint ankylosis, whose age varied from 9 to 53 years old (average 24.5 years old), in department of Oral and Maxillofacial Surgery, Stomatological Hospital, the Fourth Military Medica...

A case of congenital temporomandibular joint (TMJ) ankylosis which caused facial disfigurement, significant reduction in mouth opening, difficulties in feeding and breathing, and general interference with physical and mental development is presented. The wide range of manifestations exceed the typical picture of TMJ ankylosis and resemble a syndrome rather than an isolated defect of the TMJ.

BACKGROUND The Temporomandibular Joint (TMJ) ankylosis in child is rare and yet the causes still remain unclear. This condition that affects the feeding and possible airway obstruction do not only worry the parents, but also possesses as a great challenge to the surgeons. Furthermore, it interferes with the facial skeletal and dento-alveolar development in the on growing child. CASE PRESENTAT...

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-f...

ankylosis patients presenting in combination with mandibular dysplasia, whether to perform IPA or distraction osteogenesis (DO) first has long been a controversial issue.4 This study aimes to provide IPA with a new graft material sufficient to prevent recurrence, to modify the protocol of performing DO 6 months after IPA, and to evaluate its efficacy in treating TMJ ankylosis patients with mand...
