Purpose: Dental emergencies vary from toothaches to oral and maxillofacial traumas. Because the number of dental emergency cases has increased recently, we analyzed characteristics of patients seen during the last 2 years, in an effort to find a trend. Methods: This study was carried out with emergency room patients visiting the Department of Oral and Maxillofacial Surgery from 2009 to 2010. Results: The total number of patients studied was 1,162; the ratio of males to females was 1.73:1. The most frequent age group was 0 to 9 years, followed by 20 to 29 years. Trauma (58.7%) was the most frequent cause followed by acute toothache, oral hemorrhage, infection, and temporomandibular (TMJ) disorder. In the trauma group, injuries of soft tissue and alveolus were prevalent. The most common causes of soft tissue injury were falls, safety violations and assault. The highest incidence of emergencies was seen in patients 0 to 9 years old (41.8%). The most common causes of jaw fracture were falls, assaults, and traffic accidents in that order. In the acute toothache group, most patients had pulpitis (41.2%). In the infection group, most had buccal space abscesses (40.0%). In the hemorrhage group, post-operative bleeding cases (80.5%) were the majority, and hemostasis was obtained mostly by pressure dressings. For the TMJ disorder group, masticatory muscle disorder (65.4%) was more common than TMJ dislocation. Conclusion: In this study, trauma was the most frequent reason for patients who visited the emergency room. However, acute toothache, hemorrhage, infection and TMJ disorders were also seen frequently. Dental emergency patients could be better treated by understanding patterns of dental emergencies and performing proper diagnoses.

Objective : The purpose of this pilot study was to examine the safety and function of the newly developed cerebrospinal fluid (CSF) reservoir called the V-Port. Methods : The newly developed V-Port consists of a non-collapsible reservoir outlined with a titanium cage and a connector for the ventricular catheter to be assembled. It is designed to be better palpated and more durable to multiple punctures than the Ommaya reservoir. A total of nine patients diagnosed with leptomeningeal carcinomatosis were selected for V-Port insertion. Each patient was followed up for evaluation for a month after the operation. Results : The average operation time for V-Port insertion was 42 minutes and the average incision size was 6.6 cm. The surgical technique of V-Port insertion was found to be intuitive by all neurosurgeons who participated in the pilot study. There was no obstruction or leakage of the V-Port during intrathecal chemotherapy or CSF drainage. Also, there were no complications including post-operative intracerebral hemorrhage, infection and skin problems related to the V-Port. Conclusion : V-Port is a safe and an easy to use implantable CSF reservoir that addresses problems of other implantable CSF reservoirs. Further multicenter clinical trial is needed to prove the safety and the function of the V-Port.

Purpose: Orbital floor fracture has open wound to maxillary sinus and if the patient has chronic maxillary sinusitis, it may be have more risk of infection, complications. The purpose of this comparative study is to be the effectiveness of prophylactic antibiotics in orbital floor fracture with chronic maxillary sinusitis. Methods: We studied 20 patients who diagnosed as orbital floor fracture with chronic maxillary sinusitis from march, 2005 to may, 2006. Among them 16 were male, 4 were female and age was ranged from 15 to 68, average was 42. A day before operation, Prophylactic antibiotics were used to 10 patients. Prophylactic antibiotics were not used to 10 patients. We defined control group as prophylactic antibiotics injection group a day before operation. After surgery, we confined use of same antibiotic for 7 days in both group. After 6 month from surgery, we compare the degree of enophthalmos from healthy side to legion side with hertel exopthalmometry(Inami, Japan) in control group and non-prophylactic antibiotics injection group. Results: In control group, comparison of discrepancy between enophthalmic eyeball and normal eyeball with Hertel exophthalmometer was 1.1 mm and non-prophylactic antibiotics injection group was 2.1 mm. In independent sample t-test, control group was showed statistically significant difference with non-prophylactic antibiotics injection group(p=0.007). Conclusions: In orbital floor fracture with chronic maxillary sinusitis, bacteria in maxillary sinus can increase post-operative complication by infecting infraorbital soft tissue, and it is thought to be antibiotic prophylaxis is play a role in decrease in degree of enophthalmos. We feel the need to further study of prophylactic antibiotics in orbital floor fracture with chronic maxillary sinusitis.

Purpose: The standard treatments of hand fractures today are fixations by K -wires, metal plates, wires and lag screws. But it is very difficult to reconstruct fractures by placing implants into small bony fragments especially in the comminuted fractures and intra-articular fractures. This paper describes a simple method of reconstruction with Histoacryl$^{(R)}$ for comminuted and intra-articular fractures in hands. Methods: 2 cases with comminuted and intra-articular fractures by crushing injury were reconstructed with Histoacryl$^{(R)}$. We performed applying Histoacryl$^{(R)}$ with swab on the bone cortex carefully to avoid Histoacryl$^{(R)}$ infiltrating into the medulla. We could rearrange and fixate bony fragments using only Histoacryl$^{(R)}$, in addition, metal plates, K-wires, wires, and lag screws could be used for secondary fixation if needed. Results: Post-operative X-ray finding of 2 patients assured that the bony fragments of the hand fractures maintained their original positions. Significant displacement and deviation, infection, nonunion, and malunion during the follow-up period were not observed. Conclusion: This study showed the possibility of using Histoacryl$^{(R)}$ in addition as a simple method of fixation in the comminuted and intra-articular hand fractures.

배경; 기관 협착의 가장 흔한 원인은 기관 삽관에 따른 합병증이다. 기관 협착에 대한 치료 방침은 병변의 범위에 따라 달라진다. 전막부분의 국소적인 병변의 경우에는 레이저 절제요법을 적용할 수 있지만, 기관의 전층에 병변이 있는 경우는 기관 절제 후 단단 문합 수술을 시행하여야 좋은 치료 결과를 얻을 수 있다. 대상 및 방법; 경상대학교병원 흉부외과에서는 1998년 4월부터 1999년 5월까지 기관 삽관의 합병증으로 발생한 기관협착증 환자 12명에게 기관협착부위를 절제하고 단단 문합 수술을 시행하였다. 결과; 수술 후 사망자는 없었고, 조기 합병증으로 일시적인 성대마비가 5명, 창상 감염이 1명에서 발생하였다. 수술 후 평균 18개월간 추적하는 동안 재협착은 발견되지 않았다. 결론; 기관 삽관 후 발생한 기관협착증에 대한 외과적 치료로서 절제 및 단단 문합술은 비교적 우수한 치료버빙라 할 수 있다.

Objectives: The purpose of this study is to retrospectively evaluate the postoperative complication rates for absorbable type-I collagen sponge (Ateloplug; Bioland) use in third molar extraction. Materials and Methods: From January to August 2013, 2,697 total patients undergoing third molar extraction and type-I collagen sponge application in the Department of Oral and Maxillofacial Surgery at Yonsei University Dental Hospital (1,163 patients) and Dong-A University Hospital (1,534 patients) were evaluated in a retrospective study using their operation and medical records. Results: A total of 3,869 third molars in 2,697 patients were extracted and the extraction sockets packed with type-I collagen sponges to prevent post-operative complications. As a result, the overall complication rate was 4.52%, with 3.00% experiencing surgical site infection (SSI), 1.14% showing alveolar osteitis, and 0.39% experiencing hematoma. Of the total number of complications, SSI accounted for more than a half at 66.29%. Conclusion: Compared to previous studies, this study showed a relatively low incidence of complications. The use of type-I collagen sponges is recommended for the prevention of complications after third molar extraction.

Objectives: The purpose of this study was to obtain a natural antibiotic from Phenol-rich compounds; for the dressing and the treatment of chronic wounds. Methods: The Phenol-rich compound sweet gel was prepared by blending four natural herbal extracts, Acacia catechu (L.F.), Momia (Shilajit), Castanea sativa, and Ephedra sinica stapf, with combination of a sweet gel medium, including honey, maple saps, Phoenix dactylifera L. (date), pomegranate extract and Azadirachta indica gum as a stabilizer. The combinations were screened by using a well-diffusion assay with cloxacillin as a control. Pseudomonas spp. was tested with our novel antimicrobial compound. The zones of inhibition in agar culture were measured for each individual component and for the compound, and the results were compared with those of the control group which had been treated with cloxacillin. Data were expressed as means ${\pm}$ standard deviations. Quantitative analyses were performed using the paired t-test. Results: The antibiotic effect of the Phenol-rich compound sweet gel was statistically shown to be more significant than that of cloxacillin against Pseudomonas aeruginosa (P < 0.05). Conclusion: Our novel approach to fighting the antibiotic resistance of Pseudomonas proved to be successful. The Phenol-rich compound sweet gel was found to be suitable for use as an alternative medicine and bioactive dressing material, for the treatment of patients with various types of wounds, including burns, venous leg ulcers, ulcers of various etiologies, leg ulcers on the feet of diabetic, unhealed graft sampling sites, abscesses, boils, surgical wounds, necrotic process, post-operative and neonatal wound infection, and should be considered as an alternative to the usual methods of cure.

Fourteen Infants with congenital cardiac anomalies underwent primary surgical Intervention within the first 12 months of life. There were eight patients with ventricular septal defect, two with total anomalous pulmonary venous return [TAPVR], and the remainders with tetralogy of Fallot, transposition of great arteries [d-TGA], Taussing-Bing malformation, and coronary A-V fistula. The age of the patients ranged from 5 to 12 months, with a mean age of 9.9 months. The mean weight was 6.7 Kg [3.8 to 9.5 KS]. Congestive heart failure persisting despite intensive medical treatment was present In 8 patients [56%], and was the most common indication for operation. Early operation was necessary in 5 of these patients [35%], because of failure to thrive and recurrent pulmonary infection. In one patient with TOF, frequent hypoxic spell prompted the necessity for early operation. In cases of VSD, TAP. VR, TOF, and coronary A-V fistula, Intracardiac repair was done with conventional cardiopulmonary bypass, chemical cold cardioplegia, and topical myocardial cooling. Deep hypothermic circulatory arrest with surface induced cooling, followed by core cooling and core rewarming, was employed .for better exposure in the cases of d-TGA and Taussing-Bing malformation. The results were however, not satisfactory. The overall mortality was 28 per cent. There were no deaths in the eight patients with VSD. The one with coronary A-V fistula survived. The other 5 cases all expired either on the table or immediately after operation. The non-fatal post-operative complications included low cardiac output, respiratory insufficiency, bleeding, and temporary A-V block. The causes of death were prolonged circulatory arrest time in d-TGA, complete A-V block and low cardiac output in TOF and Taussing-Bing malformation and prolonged bypass time and Inadequate correction in TAPVR.
