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.

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 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.

말단 신경 절제술에의한 삼차 신경통 치험례

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.

The purpose of this study was to evaluate the bone-forming capacity of the periosteum in calvaria of rats. The experiment was carried out in 49 rats. We exposed the calvaria and made 1㎝ diameter round full thickness defect at both sides of calvaria. In the left calvarial bone serving as control, the periosteum was removed after implantation of block, while in the right calvarial bone the periosteum remained intact as an experimental site. The histologic examination of bone response was performed after 1-, 2-, 4-, 6-,8-, 12-, 24-week implantation in calvaria of rats. We could observe the periosteal preservation favorably influenced the bone formation.

구강악안면영역에서의 Medpor™ 의 임상적용

Recently, for the reconstruction of bony defect and cosmetic improvement, many graft materials and implants have been widely used in the various surgical situations. The alloplastic materials have many advantages such as simplicity of operation, no additional need of surgery, and easy manipulation. The MedporTM(porous high-density polyethylene, Porex Co., USA) was initially studied in 1972 for surgical implant and introduced as an implant material for oral and maxillofacial region by Sauer and King in 1988. This material permits full ingrowth of bone into the implants, substantially increasing the implant' s incorporation into the recipient site. It can be shaved during the surgery, which results in an improvement and prefabricated various size and shapes to fit into the surgical defect. The MedporTM was used in 32 patients from 1995 to 1997 at the maxillofacial region. It was used for paranasal augmentation in 24 cases, for malar augmentation in 2 cases, for infraorbital augmentation in 2 cases, for mandibular angle augmentation in 2 cases, for mandibular body augmentation in 2 cases, for chin vertical augmentation in 1 case. It was mainly fixed with miniplate or screw. There were few complications except one infection and one exposure of the implant.

상악골 완전절제후 발생한 기뇌증의 치험례

The patient was diagnosed as squamous cell carcinoma on the left palate and Lt. maxilla with T₄N₀M₀, stage Ⅳ. After 2 cycles of chemotherapy, we performed total maxillectomy under general anesthesia. During the operation, the anterior ethmoid bone was removed, and then cerebrospinal fluid leaked. The perforated site was plugged with surgical, gelform, and temporal muscle. The plain skull film and computerized tomogram provided prompt diagnosis as subdural pneumocephalus. As the fluid pours out, air bubbles fills to the top of the container and the possible mechanism for entry of air into the intracranial compartment is analogous to the entry of air into an inverted bottle. Pneumocephalus appears to be one possible complication during total maxillectomy of the ethmoid bone involved.
