Purpose: Surgical approaches to the condylar neck and subcondyle area can cause some morbidity such as, facial nerve injury, time-consuming nature and external scar etc. So many surgeons hesitate using open reduction and internal fixation for the treatment of subcondylar fractures. We report open reduction and internal fixation of subcondylar fractures in 13 adult patients via transmasseteric approach. Methods: From 2007 to 2009, 13 adults with subcondylar fracture of mandible were treated with open reduction and internal fixation via transmasseteric approach. A preauricular incision was extended downwards in a curvilinear fashion in the cervicomastoid skin crease. Skin flap was elevated above the SMAS layer. Masseter muscle was splitted at the anteroinferior edge of the parotid gland. After the fracture was reduced, fixed with appropriate plates and screws. All operation were performed under general anesthesia. Results: Mean follow-up period was 13.3 months. There were no signs and symptoms of facial nerve injury, difficulty in mouth opening, or malocclusion. Dissection time was roughly within 30 minutes. Conclusion: Transmasseteric open reduction and internal fixation of mandible subcondylar fracture can be performed with excellent visualization, and inconspicuous scar. It also offers swift access to the subcondylar area while substatially reducing the risk to the facial nerve and eliminating the complications associated with transparotid approaches.

The author has evaluated the panoramic image clarity of the midfacial anatomic structures in dry skull according to the skull position. The radiopaque markers were attached to the anatomic structures: infraorbial rim, upper and lower borders of zygomatic arch, pterygomaxillary fissure, lateral pterygoid plate, pyriform aperture of nasal cavity, lateral wall of maxilla, orbital floor, infraorbital foramen, and nasal floor. Position of the skull were divided into four groups. standard, 25mm forward, chin-down, chin-up position. The results were as follows: 1. The pyriform aperture of nasal cavity, lateral wall of the maxilla, orbital floor, infraorbital foramen and nasal floor did net cast any discernible image. 2. Nearly all images of midfacial structures were blurred in the chin-up position. 3. The forward position provided good visualization of the maxillary sinus. 4. The chin-down position provided good visualization of the zygomatic arch, pterygomaxillary fissue, and lateral pterygoid plate.

This study was performed to investigate the average anthropometric value of normal Korean men and women and to compare the preceding literatures. Additionally, average Korean profilogram was made to serve as a template for diagnosis of facial form. Eighty five Korean subjects(41 men, 44 women) aged between 21 to 26 were selected by members of the author's department on the basis of intact dentition and Class I occlusion without facial asymmetry. Frontal and lateral photographs were taken under standardized condition with digital camera. The image was magnified and adjusted according to the FH plane of cephalometric radiographs and digitized using personal computer. To compare the Western beauty, 25 esthetically pleasing female was selected to measure various angle and distance of the face. 1. It was possible to calculate the mean coordinate value of Korean normal samples which enables the direct visualization and comparison with the use of template. The method in this study was easy to applicate under the Microsoft $Windows^{(R)}$ bases. 2. Maxillary vertical hypoplasia, upper and lower lip protrusion was characteristics of Korean norms and relatively narrow alar base distance, less conspicuous nasal projection was observed. As the vermilion exposure and upper lip length was more than western norm, chin looks shorter than western. To compare the Korean and Western esthetically pleasing profile, facial convexity and nose was less conspicuous in Korean women.

Zygomatic fractures are the second most common facial bone fractures encountered and treated by plastic surgeons. Stable fixation of fractured fragments after adequate exposure is critical for ensuring three-dimensional anatomic reduction. Between January 2008 and December 2010, 17 patients with zygomatic fractures were admitted to our hospital; there were 15 male and 2 female patients. The average age of the patients was 41 years (range, 19 to 75 years). We exposed the inferior orbital rim and zygomatic complex through a lateral brow, intraoral, and subciliary incisions, which allowed for visualization of the bone, and then the fractured parts were corrected using the Carroll-Girard T-bar screw. Postoperative complications such as malar asymmetry, diplopia, enophthalmos, and postoperative infection were not observed. Lower eyelid retraction and temporary ectropion occurred in 1 of the 17 patients. Functional and cosmetic results were excellent in nearly all of the cases. In this report, we describe using the Carroll-Girard T-bar screw for the reduction of zygomatic fractures. Because this instrument is easy to use and can rotate to any direction and vector, it can be used to correct displaced zygomatic bone more accurately and safely than other devices, without leaving facial scars.

Hemangioma is one of the most common congenital tumors in the region of the face and neck. Although histologically benign, these facial masses are clinically malignant for their deforming and inexorable growth, especially in so-called 'cavernous hemangioma'. Carvenous hemangioma is the most common primary tumor occurring in the adult orbit. This tumor has symptoms that characteristically develop over several years with slowly progressive proptosis, eyeball deviation, hyperopia, diplopia and optic nerve compression. Today, hemangiomas are being treated by various methods; steroids, electrocoagulation, injection of sclerosing agent, cryotherapy, radiation therapy, laser therapy, and surgical treatment, etc. In principle, surgical approaches to the orbit must provide maximum safety and optimal visualization. We have experienced a case of large cavernous hemangioma in the orbit inferolaterally. The surgical treatment of tumor was achieved by the bicoronal approach combined with inferomedial and inferolateral orbitotomy. This surgical approach allows better visualization of the tumor and greater protection of essential anatomic structures. We obtained satisfactory results in terms of aesthetic and functional consideration. We present our case with a brief review of the literature related to orbital cavernous hemangioma.

The purpose of this article is to re-examine the roentgenographic appearance of alveolar osseous in an effort to determine the value of the orthopantomogram in the diagnosis of periodontal disease. A total of 158 osseous lesions from 13 human dry skulls were studied. 14 Ultra-speed periapical films, 2 bitewing films and Kodak panoramic film are used to obtain radiographs of all defects. The bisecting technic was used, with a target-film distance of. 8 inches and exposure factors of 70 kVp, 10MA and 0.4 sec. at anterior teeth, 0.6 see at posterior teeth in exposure time. For orthopantomogram, Panoura Eight-C was used with a exposure factors of 90kVp, 10MA. and 15sec. exposure time. All films were developed in a light. tight darkroom at 68°F for 4½ minutes. Comparison of orthopantomogram and intraoral films on the view-box was carefully studied in relation to the types of osseous defect visually evident; Proximal intraosseous defects, Interproximal craters, Interproximal hemisepta, Furcal defects on multirooted teeth, and Facial or Lingual one-walled defects. The results obtained were as follows; 1. Proximal osseous defects throughout the dental arches and furcal defects on facial and lingual surfaces of multirooted teeth can be identified with a high degree of accuracy from their orthopantomographic appearances. 2. Lesions on facial or lingual surface of the alveolar arches are rather difficult to locate or recognize on the dental radiographs. 3. In determining whether the proximal and furcal lesions are located facially or lingually, Orthopantomogram is superior to the conventional film Orthopantomogram obtained with standardization of head in proper position revealed the complete visualization of alveolar bone without showing occlusal surface of molars and proximal superimposition of teeth. Thus, on the standardized orthopantomograms, The roentgenographic characteristics of each defect were determined.
