The mandibular fracture in children is rare than adults. The features of fracture and techniques for treatment of mandibular fracture in children is various and poses special problems of reduction and immobilization of the fractured fragment. Acrylic resin splint with circumferential wiring is a valuable fixation which permits the movement of the jaw immediately after operation. The present studies reveal that acrylic resin. splint with circumferential wiring may be successful fixation for the management of mandibular fracture in children.

This is a case report that deals with TMJ remodeling after both condylar fractures in a puberty child. Patient, 14 years old boy, was referred to our department from local hospital for the evaluation of the traumatic injuries on the face which was developed by traffic accident 10 days ago. On the basis of clinical and radiographic examinations, he was diagnosed as both mandibular condyles and symphysis fractures, right maxillary alveolar fracture, and multiple teeth injury. The mandibular and maxillary fractures were treated with closed reduction and intermaxillary fixation with arch bar and multiple loop wiring. IMF was applied for two weeks and early movement of jaw was carried out to prevent TMJ ankylosis. Endodontic and prosthodontic treatments were performed for the restoration of the missing teeth. Patient was examined periodically for the evaluation of TMJ function and remodeling. On the 10th day after trauma (on the admission day), the intracapsular both condylar fractures were observed in the panormaic view. The both fragments were displaced anteriorly which were located below the articular emnences. The contour of fragments was superimposed with condylar stump in the panormaic view. In the P-A mandible view, both fragments was slightly displaced to the medial side. On the 3rd week after trauma (after removal of IMF), the contour of condylar fragments were slightly disappeared and the radiopacity of both TMJ was observed, but the sigmoid notches and coronoid processes were seen as normal contour. On the 3rd month after trauma, the fragments of condylar heads resorbed completely and the articular surfaces of condyle became round in shape. Both coronoid processes were elongated and the articular space was observed distinctly. On the 9th month after trauma, condylar processes similar to normal were repositioned anterior to glenoid fossae. The deepening of sigmoid notch and elevation of coronoid process to zygomatic arch were noted. Articular fossa became to be shallow and articular eminence was flattened. On the 18th month after trauma, the complete resorption of condylar fragments and remodeling of condyle were observed. Deepended sigmoid notch and elongated coronoid process were apparently recognized. Condylar heads were repositioned anterior to articular fossae in the panoramic view. In the P-A mandible view, left condyle was seen as normal, but the neck portion of right condyle was markedly curved to lateral side. In spite of the changes of TMJ function and structures, viz elongation of coronoid process, deepending of sigmoid notch, flattening of articular fossa and eminence, and anterior repositioning of condylar process, patient complained nothing and could function absolutely.

Ultrasonography is known to provide valuable information concerning the size, nature and location of soft tissue lesions. So that It was utilized for diagnostic purposes for the ten years. It was originally utilized mainly in opthalmology and obstetrics and gynecology. But in recent years, it was very useful in diagnosis of soft tissue masses In oral and maxillofacial area. This technique is non-invasive and inexpensive, and has not radiation hazard when compared to computerized tomography. Ultrasonography is capable of differentiating not only cystic form solid lesions but also can be helpful in the diagnosis of malignant vs. benign masses. A ultrasonic study was performed in 5 patients with various soft tissue lesions in oral and maxillofacial region (cystic hygroma, intramuscular hemangioma, neurilemmoma, tuberculous lymphadenitis, abscess) using B-scan(gray scale) ultrasonography. The results are summerized below. 1. Cystic hygroma showed internal echo free pattern, enhancement of posterior detail and multiloculated well delineated oval shaped outline. 2. In intramuscular hemangioma, ultrasonography demonstrated internal echo free pattern and two posterior attenuation were made by two calified body. 3. Neurilemmoma showed homogenous internal echo pattern, and well delineated oval shaped outline. 4. In tuberculosis lymphadenitis, internal nature was not coincided with computerized tomography, but size and location were coincided with that. 5. Suppurative abscess on masseter muscle showed internal echo free pattern.

顎下部에 發生한 Cystic Hygroma의 治驗例 및 文獻的 考察

This is to report a case of cystic hygroma occured in the left submandibular area of 12 year-old male patient. The patient was admitted to Department of Oral and Maxillofacial Surgery, Kyung-Hee University Medical Center with the chief complaints of left submandibular swelling. Cystic hygroma are a benign neoplasm of developmental origin that are characterized by large endothelial-lined space and found predominantly in the region of the head and neck, commonly in the posterior trianglar of the neck, but in this case, the lesion was found in the anterior triangle. In this case, cystic hygroma is not invade the floor of the mouth and base of the tongue and surgically excised specimen is ovoid, lobulated and 6㎝ × 2㎝ × 4㎝ in size and that is filled with watery, straw-colored fluid. The histological appearance is that of multiple dilated and collapsed lymphatic channels lined by a single layer of flattened endothelium. Focal lymphocytic infiltration as well as small sprouts or buds of lymphangiomatous tissue may extend into adjacent tissue. It is best treated by surgical excision soon after recognition in order to prevent extensive local growth and expansion. This case is of interest because their diagnosis was made when the patient was 12 year-old male patient.

We had presented a case of benign cementoblastoma of left mandibular body area of 16 year old female patient. The benign cementoblastoma, as defined by the W.H.O., is a neoplasm characterized by the formation of sheets of cementum-like tissue which may contain a very large number of reversal lines and be unmineralized at the periphery of the mass or in the more active growth area. The patient was admitted to Department of Oral & Maxillofacial Surgery, Kyung Hee University Medical Center with chief complaint of painless swelling on the left mandibular body area. We were certained of benign cementoblastoma through clinical and radiographic feature, and then performed surgical enucleation of tumor including removal of involved teeth. After 9 months follow up check, we noticed the bony replacement of operation site and no recurrence and so patient had an temporary removable partial denture.
