A 13-year-old neutered male Poodle dog was presented with a third eyelid mass in the left eye. The dog had undergone local resection of the mass about a year prior in a private practice. On cytological examination, the mass was diagnosed as adenocarcinoma. Although lung and lymph node metastases were suspected, based upon the computed tomographic results, exenteration was performed to relieve chronic pain and to improve the dog's quality of life. Exenteration carried a good prognosis with no tumor recurrence until 1 year and 10 months after surgery, when local recurrence occurred near the left zygomatic arch.

The purpose of this study was to evaluate the utilization of the orthopantomograph as a diagnostic aid to observe maxillary sinus and adjacent structures. For achieving this goal. the lead plates were attached to the five walls of the maxillary sinus of a human dry skull. The dry skull was placed in fourteen different positions; standard. 20mm forward. 20mm backward. 10 degree upward. 10 degree downward. 20mm lateral. forward & upward, forward & downward. forward & lateral. backward & upward. backward & downward, backward & lateral. upward & lateral. downward & lateral position. The obtained results were as follows: 1. The image of the medial wall was observed very differently according to the head positions. 2. The image of the anterior wall was observed at medial third to half of the maxillary sinus in each head position. 3. the image of the posterior wall was always observed at lateral third of the maxillary sinus in all head positions and more obviously in the downward-lateral position. 4. The image of the superior wall was observed at the inferior third to half of the orbit in each head position. 5. The image of the inferior wall was always observed at the inferior third of maxillary sinus in all head positions and observed more obviously in the standard and downward-lateral positions. 6. The images of the zygomatic process. zygomatic arch and zygomaticotemporal suture were observed very well in the downward-lateral position.

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 5 years(1999-2003), and compared with retrospective study during former 5 years(1992-1996) in Dept. OMS Pusan Univ-Hospital. We are assessed the cause, type, demographic ect. And analyzed alterations of facial bone fractures during past 2 periods. the results were as follows. The total number of patients was increased slightly. 429 patients treated for maxillofacial fractures between January 1992 and December 1996 and 466 patients treated between January 1992 and December 1996. The male-to-female ratio reduced in the second period by a factor of 0.7. Patients in the age groups of 10-19 years and 20-29 years increased by a factor of 4.2 and 7.9 in the second period. Assaults and falls in the second period decreased by a factor of 15.4 and 7.9. But, traffic accidents and slip downs in the second period increased by a factor of 6 and 6.6. The mandibular fractures(70.6%) showed the highest incidence, followed by zygomatic bone and arch fractures(7.5%), maxillary bone fractures(4.0%), and nasal bone fractures(4.0%). In the second period, the mid-face fracture was increased slightly. So, the mandibular fractures(69.0%) followed by maxillary bone fractures(12.9%), zygomatic bone and arch fractures(8.0%), nasal bone fractures(7.0%). Ramus fractures and body fractures of mandible was increased slightly in the second period.

The purpose of this study was to investigate the epidemiology of midface fractures. We observed clinically 71 patients with midface fracture who visited the Department of oral and maxillofacial-surgery, Chosun University, Dental Hospital, from 1991 to 1994. The results obtained were as follows. 1. There was the highest age incidence in the third decade(29.6%). 2. There was the highest incidence in the summer(36.6%). 3. The most etiologic factor of midface fracture was traffic accidents(43.6%) and next factor was fall down(38.0%). 4. The highest incidence fracture was zygomatic arch(38.7%) and next fracture was ZMC fracture(31.5%). 5. Most midface fracture was treated within 2 weeks(86.7%). 6. Midface fractures was most frequently combined with mandibular fracture(15.5%), head injuries(14.1%), orthhopedic injuries(8.5), thorax & abdomen(5.6%). 7. The highest complication was the nerve injury(8명), and next complications were infection(3명), epiphora(3명) etc.

This is a retrospective study on 452 patients with maxillofacial bone fracture. The patients were treated at the Dept. of Oral and Maxillofacial Surgery, WON KWANG UNIV. HOSPITAL from Aug. 1, 1984 to Sept. 30, 1988. The results were as follows. 1. The facial bone fractures occured most frequently in the twenties (35.3%)and male were predominant(75%) than female. 2. The most frequent etiologic factor was traffic accident. 3. The most common location of facial bone fracture was mandible(57%). Zygomatic bone & arch(39.9%) were most common on middle 1/3 of the face and symphysis(37.1%) were most common on the mandible. 4. The time from injury to treatment was variable from under the 1 week (65%) to over the 1 week(35%). In most case of the patients were treated beyond the 3 days(51.5%). 5. The relationship of intermaxillary fixation period and treatment method was an intimate relationship. The IMF period was reduced by the use of plate and screw osteosynthesis. 6. The weight loss was proportioned to intermaxillary fixation period.

This is a retrospective study on facial bone fractures of Koreans. This study was based on a series of 110 patients who had been treated for facial bone fractures as in-patient at Guro Hospital, School of Medicine, Korea University for the period of September, 1984. to August, 1988. The results were obtained as follows : 1. 2nd decade(42.7%) was the highest age group in incidence, and age range was 2 years to 72 years, and the ration of Male/Female was 3.7 : 1. 2. Falling was most frequent cause of facial bone fractures(40.9%) 3. The frequent location of facial bone fractures were mandibule(67.1%), zygoma & zygomatic arch(11.7%), maxilla(10.9%), and others in order. 4. In mandibular fractures, one site fractures showed 30.1% and two site fractures showed 58.8% and triple site fractures showed 11.1%. The most frequent site of mandibular fracture was symphysis(32.7%) 5. The most frequent month of facial bone fracture was September.

Foreign body (FB) impaction in the maxillofacial area could be caused by knives, glass fragments, and vegetative materials. We present the rare case of a 62-year-old man with a large glass FB in the left cheek retained for over 40 years. He had traffic accident over 40 years ago and glass fragments impacted on his left cheek. Glass fragments were retained around the zygomatic arch with dimpled scar and unclear serous discharge, but other facial motor or sensory dysfunction was not observed. We confirmed three glass fragments with radiologic examination including plain radiograph and computed tomographic image. Under general anesthesia, impacted glass fragments were removed through the direct incision on the dimpled scar and the additional incision on the left lateral canthal area. Remnant FBs were not seen on an intraoperative C-arm radiograph. After 2 days of irrigation for inflammation control, the dimpled wound was sutured. The wound was healed without major complication and the original dimpled scar was much improved.

Strabismus is a misalignment of the eyes. It is divided into paralytic strabismus and non-paralytic strabismus. There are so many causes in paralytic strabismus, and the oculomotor nerve palsy is one of them. Many studies reported the etiology and clinical features of oculomotor nerve palsy. Common causes of oculomotor nerve palsy are idiopathic, vascula.; disease, aneurysm, head trauma, neoplasm and miscellaneous. Recently the proportion of traumatic cause has been increased, but the treatment is difficult as it used to be. In this case report, one case of traumatic oculomotor nerve palsy with zygomatic arch Fx and clavicle Fx were treated by herbal medicine and acupuncture. After Treatment, symptoms- ptosis, deviation of Lt. eye to downward & outward in primary position, diplopia, limited adduction & elevation & depression, dilated pupil without pupil reflex- were improved. There are so many hypothesises but no definite guide lines are established about the oriental medical treatment of oculomotor nerve palsy, so we expect the establishment of definite guide lines by further clinical studies.

The purpose of this study was to analyze the stress distribution and the displacement in the maxillary complex after the application of the reverse headgear. The direction of force was parallel to the occlusal plane. Orthopedic force,300gm, was applied to the maxilla of the dry human skull in a forward direction. The stress distribution and the displacement within the maxillary Complex was analyzed by a 3-dimensional finite element method. The results were as follows: 1. The stress distribution at the molar region was greater than that at the anterior. 2. The stress distribution at the lateral side of the premaxilla was greater than that at the middle aide, especially high stress was noted at the canine eminence. 9. Compressive stress was noted only at the frontozygomatic suture of the zygomatic arch. 4. A forward, upward, and sideward displacement was noted at the entire nodal points of the zygomaticomaxillary suture portion. A displacement with a slight rotation was observed on the transverse palatine suture. 5. The maximum stress was observed at the lateral side of the maxillary tuberosity area, and generally the forward and downward displacement was noted at all this area.
