A rare case of aneurysmal bone cyst (ABC) located in the mandibular condyle in a 10-year-old boy is presented. The patient came to our attention for a sudden swelling in the right temporomandibular region, the mouth opening was not reduced. A rapid growing mass, depicting soft tissue invasion, in the right condyle of the mandible was found. Clinically and radiographically it resembled to a mali...

There are some difficulties in approaching and removing the lesion in infratemporal fossa because of its anatomical location. After wide excision of tumor lesion, it is also difficult for reconstruction of mandibular condyle and cranium base on infratemporal fossa. Besides, there are some possibilities of cerebrospinal fluid leakage, intracranial infection and bone resorption. It is also challe...

OBJECTIVE The purpose of this study was to investigate the expression pattern of Runx2 in mandibular condylar cartilage, a type of secondary cartilage. METHODS Mandibular condyle of ddY mice were fixed from embryonic day 14 (E14) through just after birth (equivalent to E19). Samples were cut into 4 micro m serial sections through the central area of the mandibular condyle at the sagittal plan...

Objective: To report a new therapeutic tactic for the old dislocation of intact mandibular condyle into the middle cranial fossa, which is extremely rare while the reported treatment methods are varied. Methods: The subject was a 29-year-old female who was diagnosed with old dislocation of intact left mandibular condyle into the middle cranial fossa and left zygomatic arch fracture. Gap arthrop...

Osteochondroma represents the largest group of benign tumors of bone, which usually develops in long bones and relatively uncommon in the craniofacial region. The condyle and coronoid tip are the most common sites of occurrence in the mandible, but both sides of condyle involved has never been reported. Here, we describe a case of osteochondroma arising from the bilateral mandibular condyle.

OBJECTIVE To compare condylar position and morphology among different vertical skeletal patterns. METHODS Diagnostic cone-beam computed tomography images of 60 adult patients (120 temporomandibular joints) who visited the orthodontic clinic of Hallym University Sacred Heart Hospital were reviewed. The subjects were divided into three equal groups according to the mandibular plane angle: hypod...

Successful intra-temporomandibular joint gene transfer is a prerequisite for gene therapy to induce mandibular condylar growth. This study was carried out to investigate the expression of recombinant adeno-associated virus (rAAV) based vector-mediated enhanced green fluorescence protein (eGFP) in the mandibular condyle. The transduction efficiencies for primary chondrocytes using different hybr...

The effect of maxillomandibular fixation on the growth of the mandibular condyle was studied in eight control and eight experimental male juvenile monkeys. All animals had metallic implants placed throughout the craniofacial complex in order to facilitate cephalometric analysis of growth-related changes in the maxillomandibular complex during jaw immobilization. Every 3, 6, 12, and 24 wk after ...

Received Jan. 2012; Received in revised form May 2012; Accepted July 2012. ABSTRACT Chondrosarcomas are slow-growing, malignant mesenchymal neoplasms characterized by formation of cartilage by the tumoral cells. They display a wide range of morphological features from a well-differentiated growing mass resembling a benign cartilage tumour to a high-grade malignancy with aggressive local invasio...
