This study was conducted to know oral maxillofacial symptoms accroding to dental fear and dental use behavior. 334 persons Older than junior high school students in Daegu, South Korea who visited to dental clinic were targeted From March 1.2008 to March 15, 2008. Statistics tool was SPSS 12.0 for Windows. General characteristics and response degree according to oral maxillofacial symptoms was analyzed by frequency study. Fear and difference according to oral maxillofacial symptoms we re conducted by T-test and One-Way ANOVA. Correlation analysis was used to verify relation between fear and oral maxillofacial symptoms. Results are followings. 1. Women felt fear higher than men did. Persons who were older felt fear higher and these were statistically related. 2. Extraoral external was 62.9%, hightest on the symptoms response degree according to oral maxillofacial symptoms. Feeling back side of the head on the strain and neck was stiff on the items were high. 3. Oral maxillofacial symptoms were high in the case when they had regular inspection, experience of scaling, experience of anesthesia and visited to the clinic often. And. Two cases(having regular inspection and visiting to the clinic often) were statistically related. Conclusion: Each pan of oral maxillofacial symptoms in the high fear group according to oral maxillofacial symptoms and it was all statistically related. And, fear and each oral maxillofacial pains were positively related and it was statistically related.

본 연구는, 기존의 나열식 분류체계의 문제점을 극복할 수 있는 GRAIL을 이용하여 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들과 관련된 치의학 개념들의 모델을 구축한 뒤, 완성된 치의학 개념 모델이 두경부의 해부학적 구조물들 및 구강 악안면 영역의 주요 질병들을 잘 표현할 수 있는지와 기존의 GRAIL 모델이 지닌 특징에 잘 부합하는지를 평가하고자 시행되었다. 서울대학교 치과병원 내원 환자 중 포괄적인 치과 치료 병력을 지닌 환자 150명의 치과 의무기록을 내용별로 분석하고, 각종 치의학 교과서와 기존의 의학용어 분류체계에서도 모델 구축에 필요한 치의학 용어를 선택하였다. 이들 자료를 바탕으로, GRAIL 모델 구축을 진행하고 구축된 모델을 평가할 수 있는 소프트웨어 프로그램인 'KnoME'에서 치의학 개념 모델을 구축하고 평가하여, 다음과 같은 결론을 얻었다. 1. 환자 150명의 치과 의무기록을 내용별로 분석한 결과, 우선적으로 모델 구축이 필요한 치의학 용어로는, 해부학적 구조물의 경우 치아, 치은, 악관절, 입술, 턱, 혀 등의 순서로 나타났으며, 구강악안면 영역의 병소에서는 치아 우식증, 치주염, 치은염, 악관절 장애, 매복 지치, 치경부 마모 등의 순서로 나타났다. 2. GRAIL을 이용하여 치아, 치주조직, 구강점막조직, 치아 우식증, 치수 및 치근단 병소, 치주질환, 구강점막질환의 모델 구축을 시행한 결과, 치의학 개념간의 다양한 관계가 대다수 잘 표현되었다. 그러나, 구강 악안면 영역의 해부학적 구조물에 대한 공간 정의의 한계성과 구강 악안면 질환의 진행 양상에 있어서 표현의 어려움이 관찰되었다. 이러한 부분은 GRAIL을 치의학 분야에 적용할 때, 극복해야 할 한계로 나타났다. 3. 치의학 개념들에 관한 다양한 질의를 시행한 후 그 응답 내용을 평가한 결과, 완성된 모델 내에서 치의학 개념의 자동적인 분류가 이루어 졌으며, 다양한 목적의 검색이 가능하였다. 이와 같은 사실로 미루어 보아서, 완성된 모델은 기존의 GRAIL 모델의 특성에 잘 부합되는 것으로 생각되었다.

Overall study was carried out for the patients visiting Department of Oral & Maxillofacial Surgery through Emergency Room in Chonnam University Hospital, from Jan. 1, 1992 to Dec. 31, 1996. Result obtained were as follows ; Male predilection was shown, the male to female ratio being 2.5 to 1. The frequently developing age group were the first 3rd and 4th decade and under the age of 9 was followed. The number of patients for emergency was peak in September and October to 11%. About the causes for emergency, traffic accident was the most, and fall down injury and assault were followed. About the injury lists, facial laceration was preceded and the next facial bone fracture and the tooth injury followed. In the facial bone fracture, fracture in the mandible only was the most, and zygomaticomaxillary complex fracture, and mandible-maxilla complex fracture were followed. when the case of the mandible fracture, symphysis, condyle, angle were marked in succession. 57% was predomunatly ranged in the timea of 18 : 00 to 03 : 00 for the emergency. From injury onset to visiting emergency room, the range of 8 hours to 12 hours was predominant. Above results suggest that urgent patients of oral and maxillofacial area were relatively so high that division of oral and maxillofacial surgery should be established immediately.

Bilateral sagittal split ramus osteotomy(BSSRO) of the mandible is an essential and commonly used procedure to correct dentofacial deformities and malocclusion. The possible complications associated with BSSRO include inferior alveolar nerve injury, bleeding, temporomandibular disorder, unfavorable fractures, and clinical relapse. The incidence of facial nerve palsy after orthognathic surgery recently reported is 0.1%. The probable etiologies have included facial nerve compression, complete or incomplete nerve transection, nerve traction, and nerve ischemia from anesthetic injection. Postoperative facial palsy is one of the most serious complications because it reduces the quality of life and significantly reduces social interaction. The case of a 24-year-old patient who underwent bilateral sagittal split ramus osteotomy is described. The medical records and postoperative photographs were reviewed in detail to collect information on the clinical course, treatment, and outcomes.

의료계에서는 사실 보이지 않게 영역문제로 갈등을 겪고 있으며 치과에서는 특히 메디컬적 성격이 강한 구강악안면외과가 성형외과나 이비인후과와 영역갈등을 겪고 있는 것으로 나타났다. 이에 구강악안면외과를 중심으로 타의과와의 영역문제와 대책에 대해서 살펴본다.

Temporomandibular joint(TMJ) and dental occlusion are important in functional aspect as well as in cosmetic aspect for craniofacial surgery such as orthognathic and traumatic surgery. During these operations, appropriate maxillomandibular fixation(MMF) is especially necessary to conserve or reconstruct, dynamic TMJ and functional occlusion. Arch bar is one of the most popular method to gain proper MMF. Seventeen patients including 5 patients with mandibular fracture, 12 patients with orthognathic surgery(6 patients had relatively normal occlusion, however 6 patients had facial anomalies such as hemifacial microsomia with irregular occlusal plane.) were joined in this study. Arch bar was contoured on the dental cast, which was prepared for model surgery, prior to apply it on the facial anomaly patient. On using pre-contoured arch bar, patients felt better during the procedure and surgeons saved time. Moreover, well-contoured arch bar promises precise transmission of force on the bone, which implies surgeons do not need to worry about the occlusion while fixing bony structures. Authors suggest how to apply arch bar to satisfy basic theories about dental row and occlusion based on the experience. In addition, it is proposed to contour arch bar on the dental impression prior to apply it on the patient who has irregular and complex occlusal plane.

중안면부의 골절은 심미적으로나 기능적으로 많은 문제를 야기할 뿐아니라 두개부와 연관되어 뇌손상의 가능성을 가지므로 생명과 직접적인 연관을 갖는다고 할수 있다. 산업사회의 고도의 발달로 인하여 자동차의 보급이 증가하고 그에 따라 교통사고의 절대수가 증가하고 안면부 골절환자가 증가추세에 있다고 볼 수 있다. 때문에 구강악안면외과의사로서 중안면부의 골절에 관심을 기울여야 할 것으로 생각된다. 중안면부 골절 가운데 비골을 포함한 안와 근심벽의 쉽게 일어나며 골절에 포함된 해부학적 구조물들이 복잡하기 때문에 골절후에 기능적 이상이 쉽게 발생될 수 있다. 본 과에서 처치한 중안면 골절 환자중 비골을 포함한 안와 근심벽의 골절환자를 경험한 바 이에 보고하는 바이다.

Fourteen masses in the maxillofacial areas which are not diagnosised simply as abscess were studied with ultrasound to evaluate its diagnostic role. Benign mass showed homogeneous echopattern with smooth margin and cyst a few internal echo with smooth margin. But malignant mass showed irregular margin, inhomogeneous echotexture and deep extension. Ultrasonography considered as an initial noninvasive imaging modality for the evaluation of maxillofacial masses.
