This study was performed to evaluate the effect of high frequency therapy applied to the region branching to the external carotid artery for peripheral facial paralysis sequelae. A patient suffering with facial edema due to facial paralysis sequelae had been treated with acupuncture, high frequency therapy on the branch area to the external carotid artery for 7 weeks. The evaluation of clinical outcome was done by degree of swelling by measuring the distance of the face and skin temperature of face through digital infrared thermographic imaging. After treatment, the patient's degree of swelling and the temperature difference between the affected side and normal side was decreased. In addition, the temperature was changed in the entire facial area as well as the treatment point of high frequency therapy. This result shows that acupuncture combined with high frequency therapy at the region branching to the external carotid artery could be an effective way to improve facial blood flow, although further clinical studies will be needed.

Although the use of the antibiotics has minimized the dangers of the spread of odontogenic infection to adjacent important organs, sometimes the fatal cases, such as Ludwig's angina, mediastinitis, intracranial complications from the odotogenic infection, may be occurred. The odontogenic infections or oral and maxillofacial region may involve the intracranial area through systemic circulation or by direct spread into the intracranial cavity. Headache, malaise, loss of appetite, chills, fever, vomiting, apathy, and irritability are usually followed by more specific involvement of the nervous system. We experienced one patient who died of intracranial complication from odontogenic infection. So we report the case and the literatures about intracranial involvements following odontogenic infections and dental procedures.

A 31 years old female had been suffered from a bony swelling in right premolar region of the mandible for 12 years, recently grown rapidly. A fistula tract developed on the right anterior mandibular border, but the lesion was relatively asymptomatic. In the radiological examination, the tumor mass was irregularly mixed with radiolucent and radiopaque areas, forming multiple cystic spaces. Under the diagnosis of calcifying odontogenic cyst, the mandibular mass was resected and examined pathologically. After decalcification, the dissected tumor mass showed multiple small cystic spaces and calcifying fibrous tissue, mimicking calcifying odontogenic cyst or ameloblastoma. Histological observation showed many calcifying cementoid materials and ossifying trabeculae. The cystic spaces were turned out to be dilated vascular channels lined by endothelial cells, containing plasma fluid. However, the main lesion was diagnosed as cemento-ossifying fibroma (COF), and the atypical vascular channels were greatly dilated and gradually expanded the whole tumor mass. The present COF was examined through immunohistochemical (IHC) array, and investigated for tumor cell characteristics, exhibiting abnormal ossification and aneurysmal cystic changes. IHC array disclosed that the tumor cells grew progressively in the lack of apoptosis, and that they showed lower expression of RUNX2 than BMP-2, RANKL, and OPG, and increases of protein expression in $HIF-1{\alpha}$, VEGF-A, and CMG2. These data suggested that the reduced expression of RUNX2, osteoblast differentiation factor, be relevant to abnormal ossification of COF, and that the consistent expressions of angiogenesis factors be relevant to de novo angiogenesis in COF, subsequently resulted in aneurysmal cystic changes.

Coronary artery CT angiography has short scanning length, the exposure dose is high. Therefore, it is required to study on the organ dose when using MDCT. We compared the differences between the absorbed dose and effective dose in the major organs assessing the absorbed dose in the major organs by 16-MDCT and 64-MDCT in the subjects with coronary artery CT angiography, the same protocol by 16-MDCT and 64-MDCT. As a result, the great orders of absorbed dose when conducting coronary artery CT angiography had been shown as heart, stomach, liver, pancreas, kidney, spleen, large intestine, lung, small intestine, thyroid gland, ovary, bladder, and orbit with the absorbed dose distribution of $0.538{\pm}0.026(Mean{\pm}SD,\;p<0.05)mGy{\sim}71.316{\pm}4.316mGy$ in 16-MDCT, and heart, stomach, pancreas, spleen, liver, kidney, small intestine, large intestine, lung, thyroid gland, ovary, bladder, and orbit with the absorbed dose distribution of $0.87{\pm}0.01mGy{\sim}115.26{\pm}1.59mGy$ in 64-MDCT, demonstrating some different distributions. The exposed doses to the patient per one time scanning with coronary artery CT angiography were $71.316{\pm}4.316mGy$ in 16-MDCT as the absorbed dose based on the heart and $115.26{\pm}1.59mGy$ in 64-MDCT. The effective doses were 7.41 mSv and 12.11 mSv in 16 and 64-MDCT, respectively. Taking into account the results of brain CT with 2.8 mSv that has comparatively large scanning length and size, facial CT 0.8 mSv, chest CT 5.7 mSv, pelvic CT 7.2 mSv, and abdominal and pelvic CT 14.4 mSv, it is very high considering the scanning length of 13 cm limited to the heart for the scanning range.

Aneurysmal bone cyst is a benign lesion of bone consisting of a septated, cystic cavity filled with non-endothelium-lined, blood-filled spaces. As it grows, expanding and destroying the affected part of the bone by direct compression, the lesion characteristically produces a prominent bulging of the affected bone, which eventually erodes the overlying cortex. Patients rarely complain of pain unless the cyst affects adjacent nerves or its expasion is great enough to impinge on the surrounding joints and soft tissue. Teeth adjacent to the cyst may be displaced, but usually remain vital. Development of the lesion in the craniofacial region is rare, and the mandible is more often affected than the maxilla. Complete surgical excision is used to treat aneurysmal bone cyst, with either curettage or composite resection. This is a case report of 49 years old female with aneurysmal bone cyst treated with surgical excision & DFDB graft.

False aneurysms(Pseudoaneurysms) and arteriovenous fistulas have only rarely been reported in the facial region. In this region the false aneurysm arises most frequently in the superficial temporal and facial artery, but other branches of the external carotid are sometimes involved, including the maxillary and lingual artery. False aneurysms can be occurred by blunt trauma that either laceration or rupture the full thickness of the arterial wall. The diagnosis of a false arterial aneurysm can be often made solely on the basis of physical examination. Angiography is helpful for conformation, for delineating the lesion and its vascular supply, and for ruling out the presence of associated vascular lesions such as arteriovenous fistulas. Ultrasonography may also be useful in delineating lesions that are not easily accessible for physical examination. Treatment of false aneurysms is excision, ligation, and arterial embolization. This is a case of false aneurysm of the lingual artery after facial trauma caused by traffic accident. The lesion was successfully treated by embolization and ligation of the lingual and facial branches of the external carotid artery.

The DiGeorge syndrome is a rare congenital abnormality consisting of aplasia or hypoplasia of the thymus and parathyroid glands resulting from malformation of the third and fourth pharyngeal pouches. This syndrome usually includes congenital cardiac anomalies and abnormal facial features. We experienced a case of congenital cardiac anomaly associated with DiGeorge syndrome. The patient was 1 month old boy weighing 3.5 kg. The congenital cardiac anomalies included ventricular septal defect, atrial septal defect, coactation of aorta, and patent ductus arteriosus. We performed one-stage operation with two separate incisions for these cardiac anomalies. Postoperative course was uneventful and the patient at 6 months of follow up is doing well.

A deep circumflex iliac artery (DCIA) flap is usually used for reconstruction in oral and maxillo-facial surgery department since introduced by O'Brien in 1975. Various flap designs are possible for osteomusculocutaneous, musculocutaneous, musculosseous and vascularized bone types. Iliac crest shape is similar to contour of mandible. Moreover, though a fibular flap has only 15~20 mm of cutting plane width, a DCIA flap contains much more bone amount, making this a similar reconstruction compare with normal mandible. A 68 year-old male with squamous cell carcinoma on the anterior floor of the mouth had an impression with T2N0Mx and the treatment procedure was DCIA reconstruction after wide resection and marginal mandibulectomy, with both supraomohyoid neck dissection. We present an experience of DCIA flap for reconstruction with a literature review.

Purpose: Inevitably, Maxillary structural defect follows maxillary cancer extirpation. Maxillary reconstruction is over every surgeon's head. Every physician tried to overcome limited donor site of craniofacial defect. We considered to suggest optimal method of inferior orbital wall defect in functional point as well as esthetic point. Methods: We performed wide excision of maxilla and vascularized partial thickness calvarial bone flap to reconstruct the defect from cancer extirpation in three cases. We select ipsilateral superficial temporal artery, vein and outer cortex of parietal bone flap as donor. And we applied bone flap as inferior orbital wall structure. The bony surface was wrapped with fascia to prevent direct contact between orbital contents and rough bony flap surface. Computed tomography image was checked during follolw up period. Results: We can observe these patients for over two years. In all three cases, We can get fair inferior orbital wall structure. Even though they got radiation therapy, there was no limitation of extraocular movements, no diplopia. no enophthalmos. Also there was minimal donor site morbidity. Conclusion: We suggest vascularized calvarial bone flap is practically excellent strategy for inferior orbital wall reconstruction.
