  • Bifid mandibular condyle (BMC) is an uncommon morphological variant of the mandibular condyle. Although authors have proposed various etiologies for BMC, no consensus has emerged. In addition, varying findings have been reported regarding the epidemiological parameters of BMC (e.g., prevalence, gender ratio, and age), possibly due to its low incidence. BMC is occasionally associated with symptoms of the temporomandibular joint, such as ankylosis, pain, and trismus; however, it is difficult to detect this condition on conventional radiographs. This study reports a case of BMC with radiographic findings, and reviews the literature on the epidemiology of BMC.

  • Maxillofacial injuries are less common in children than in adolescents and adults. This lower incidence is a result of the relatively small size of mandible, the resilient nature of the bones, and a relatively protected environment, which distinguish the treatment principles of pediatric mandibular fractures from those of the adult. The bone of child is malleable, so pediatric fractures tend to be less displaced and rarely comminuted. Moreover, high regeneration potential of the wound allows more conservative treatment modalities for the pediatric mandibular fracture. High risk of damaging unerupted tooth bud renders many clinicians to resort to more conservative treatment modality for the reduction of displaced segments. This case report describes two successful treatment cases using the circummandibular wiring which was applicated to the fracture on parasymphysis of mandible. Circummandibular wiring can protect the tooth buds, and there is no need for intermaxillary fixation so that it prevents the possible complications of intermaxillary fixation such as the temporomandibular joint ankylosis and the facial growth disturbances. The acrylic splint was removed after 3 weeks, which showed clinically good union across the fracture line without complications. They showed complete clinical and radiological bone healing with an optimum occlusion.

  • Mandibular fractures occur with high incidence among various fractures in maxillofacial region in children. Jaw fractures in children should be approached differently than in adults because bone growth continues throughout childhood. As far as displacement of the fragment is not severe, or if it is condyle that is fractured, closed reduction and additional intermaxillary fixation can be considered. Functional exercise is also required to prevent ankylosis of temporomandibular joint. Several complications, particularly malocclusion and facial asymmetry due to growth disturbances, can occur after condylar fractures. If growth disturbances take place after mandibular fractures, catch-up growth may occur in some patients, thus, periodic observation is necessary. In case of persistent growth disturbances, functional devices may be used to prevent severe facial asymmetry. This case report describes the long-term follow-up of two patients with facial asymmetry after mandibular fracture.
