Tetralogy of Fallot is a congenital cardiac anomaly characterised by a large ventricular septal defect, right ventricular outflow tract obstruction, dextroposition (or rightward deviation) of the aorta and right ventricular hypertrophy. The patient with congentital heart disease who is asymptomatic dan receive any indicated dental treatment as long as antibiotics are used to prevent bacterial endocarditis. This is a case report of the acute supporative osteomyelitis on mandible treated by sutgical correction in TOF patient.

The longer the mandible remains dislocated, the more difficult is the management of the condition. Muscle relaxation and manipulation may reduce the dislocation after a few minutes or hours ; however, the passage of time brings more severe muscle spasm and fibrotic preauticular changes, increasing the problem. Manual reposition is not possiblem anymore in most cases. Most of the reported case of prolonged dislocation have been treated surgically. The following report discusses a case of anterior dislocation of the mandible of five months' duration that was treated successfully by the conservative method using the bone hook.

Trigeminal neuralgia (tic douloureus', is a painful paroxysm of one of the branches(usually, the second or third division) of the trigeminal nerve, and the neuralgia may related to disseminated (multiple) sclerosis, to anoxia from vasospasm. or to ischemia from other casuses in the region of the gasserian ganglion or sensory root. Trigeminal neuralgia has been treated by drugs, nerve injections, surgery, and acupuncture. The drugs used in the past, such as as diphenylhydantoin(Dilantin), have largely been supplanted by carbamazepine(Tegretol), and it has proven remarkably effective in controlling the pain of trigeminal ueuralgia. Nerve blocks of the trigeminal ganglion that use alcohol, phenol, or hot water have also been reported to bring relief. Trigeminal tractotomy may or may not relieve the condition. However, surgical division of the sensory root in the medulla oblongata gives permanent relief. Other forms of treatment include trigeminal decompression and percutaneous electrocoagulation to cauterize the trigeminal nerve. Peripheral neurectomy is an effective treatment of trigeminal neuralgia because it interrupts the flow of a significant number of afferent impulses to the central trigeminal apparatus. We had performed peripheral neurectomy in a case. The pain free period obtained by peripheral neurectomy and the drugs (carbamazepine) in patient with trigeminal neuralgia and orofacial pain is significant. The purpose is to report our observatoni on the case report and the effectiveness of peripheral neurectomy of buccal nerve.

Of pathologic hard tissue lesions developing in jaw, the oral and maxillofacial surgeon and dental practitioners easily meet the cystic lesions, but these cystic lesions have the specific respective pathway on developing mechanism. When early detected. these cystic lesions are treated by simple enucleation and bone graft. but when treatment being delayed, these produce the large defect of jaw. Odontogenic cysts are currently thought to arise from proliferation of reduced enamel epithelium, tooth germ, and oral epithelium. It is not to difficult to diagnose these lesions, but lining epithelium of odonogenic cyst can be keratinized progressed to ameloblastoma and other malignant lesions. In those cases, lesions have the high recurrence rate and other clinical behavior. This female patient was 16 years old and had the operative istory of multiple keratocyst in jaw. The patient was admitted with multiple dentigerous cyst at different areas at this time. Patient didn't show any signs or symptom in related with any syndrome. We thought this case is very rare, so report it with a review of literatures.

This is a case report of asymmetrical mandibular porgnathism with TMJ disorder. A patient, who had been sufferring from the maticatory difficulties resulting from the significant malocclusion with posterior cross bite and the facial disfigurement due to asymmetrical mandibular prognathism, visited to our Dept. for further evaluation and definitive treatment. About TMJ problem, the conservative treatment such as occlusal splint, myo-therapy, and orthodontic treatment was done preoperatively, and the orthognathic surgery was followed by means of sagittal split ramus osteotomy on the right side and vertical ramus osteotomy on the left side. In one year postoperatively, there were no significant complications such as compromised healing, poor segment position, malocclusion, and decreased function. The patient was satisfied with corrected dentofacial deformity an resolved TMJ disorder. The results are as follows: 1. This case was mandibular prognathism associated with TMJ disorder which was developed by the occlusal dysfunction and the emotional stress due to facial disfigurement. 2. In case of mandibular prognthism with TMJ disorder, the further cooperated studies of D/ oral and maxillofacial surgery, otrhodontics, and prosthetics were much necessary to achieve normal function after surgical repositioning of the jaws.

The congenital deformities of cleft lip and cleft palate have been known to afflict man since prehistoric time. Efforts to correct these abnormities have evolved over the centuries as scientific knowledge has advanced. Although there is no agreement as to when the surgery should be performed, most surgeons adhere to "rule of 10" : the infant must be 10 week old weigh 10 Ibs, have a hemoglobin value 10gm/㎗ and have a white blood cell count no greater than 10 thousands/㎣. Consensus favors performing initial palatal surgery in the child when he is between 18 and 24 months old. The timing of cleft alveolus surgery is usually between 10 and 11 years old. In the period from 1992 to 1996, 38 patients with cleft lip and cleft palate treated at the department of oral and maxillofacial surgery, Chosun university, dental hospital were analysed clinically. The obtained results were as follows. 1. The ratio of male to female was 1.92 : 1 (25/23) 2. The ratio of cleft lip, cleft palate and cleft lip & palate was 1.5 : 1 : 2.5 (12/8/18) 3. The ratio of unilateral to bilateral cleft lip was 5 : 1 (25/5) 4. The ratio of left to right side in unilateral cleft lip was 1.5 : 1 (15/10)
