배경 및 목적: 관상동맥 우회술 후의 중추신경계 합병증은 수술의 성과를 결정짓는 중요한 합병증 중의 하나로서, 심폐바이패스의 사용은 중추신경계 합병증 발생의 빈도를 증가시킨다. 이러한 중추신경계 합병증의 발생빈도를 낮출 수 있을 것으로 생각되는, 심폐바이패스를 사용하지 않는 관상동맥 우회술을 시행하고 그 결과를 분석하였다. 대상 및 방법: 1995년 2월부터 1998년 12월까지 심폐바이패스를 사용하여 관상동맥 우회술을 시행했던 223례의 환자를(I 군) 대상으로 하여 수술 후 중추신경계 합병증의 발생을 조사하였고, 이를 1998년 1월부터 1999년 6월까지 심폐바이패스를 사용하지 않고 관상동맥 우회술을 시행한 115례의 환자(II 군)의 결과와 비교하였다. 수술을 시행했던 모든 환자에서 수술 전 두 개 내,외의 동맥계에 대한 검사로 경두개 초음파검사 및 경동맥 도플러검사를 시행했으며, 이 검사들에서 의미있는 병변이 발견되는 경우 뇌자기공명영상 및 뇌자기공명 혈관조영술을 시행했으며, 이를 바탕으로 수술 전,후 신경과 의사의 신경학적 평가를 받았으며, 중추신경계 합병증은 Coffey 등이 분류 정의한 바와 같이 뇌졸중, 경련발작, 일과성 섬망 및 저산소성/대사성 뇌증으로 구분하였다. 결과: 심폐바이패스를 사영하였던 I군에서의 중추신경계 합병증의 발생빈도는 총 223례 중 61례(27.3%)였고, 심폐바이패스를 사용하지 않았던 II군의 총 115례의 환자들 중 수술 후 중추신경계 합병증이 8례(7.0%)로 두 군간에 유의한 차이가 있었다(p<0.005). 결론: 심폐바이패스를 사용하지 않는 관상동맥 우회술의 시행으로 술후 중추신경계 합병증을 현저히 줄일 수 있었음을 확인하였으며, 향후 합병증 발생의 고위험군에서 이 수술의 적용이 더욱 확대되어야 할 것으로 사료된다.

PURPOSE : This is to review the complicated jaw fractures that had been referred for revision of the unsatisfactory results, and to provide proper managements for the easily complicated jaw fractures. MATERIALS & METHODS : Twenty-nine patients who had been revised due to malunion or complicated fractures of facial bones for last 3 years were reviewed. The main problems required for revision, type of fractures complicated, the primary managements to be reclaimed, the specialties to be involved, the management to be reclaimed, time elapsed to seek reoperation, type of revision surgeries, residual complication were analysed with medical records, radiographs and final examinations. RESULTS: The major complaints were malocclusion(79.3%), facial disfigurement(41.3%), TMJ problems (13.7%), neurologic problems(10.3%), non-union(10.3%), and infection(6.8%). Unsatisfactory results were occurred most frequently after improper management of the multiple fractures of the mandible (62.2%), combined fractures of maxilla and mandible (20.6%), fracture of zygomatico-maxillary complex and midpalate (17.2%). The complications to be corrected were widened or collapsed dental arches (79.3%), improperly reduced condyles (41.3%), painful TMJ (34.4%), limited jaw excursion (31.0%), over-reduction of zygoma (13.7%), and nonunion with infection(13.7%). and dysesthesia (10.3%). The primary managements were nendereet by plastic surgeons in 82.7%(24/29) and by oral surgeons in 7.6%(2/29). Main causes of malunion are inadequate ORIF in 76%, unawareness & delay in 17%, and delayed due to systemic cares in 17%. 76% of 29 patients had been in state of intermaxillary fixation for over 4 weeks. Revision were done by means of "refracture and ORIF"in 48.2%(14/29), orthognathic osteotomies with bone grafts in 55.1%(16/29), and camouflage countering & alloplastic implantations in 37.9%(11/29), TMJ surgeries in 17.2%, micro-neurosurgeries in 11.6%. Residual complications were limited mouth opening in 24.1% (7/29), paresthesia in 13.7%, resorption of reduced condyle in 10.3%. CONCLUSIONS : Failure of initial treatment of jaw fractures is due to improper diagnosis and inadequate treatment with lack of sufficient knowledge of stomatognathic system. It is crucial to judge jaw fracture and patients accurately, moreover, the best way of treatments has to be selected. Consideration of these factors in treatment could minimize the complication of jaw fractures.

Purpose: In accordance with the increasing number of accidents caused by various reasons and recently developed fine diagnostic skills, the incidence of orbital blow-out fracture cases is increasing. As it causes complications, such as diplopia and enophthalmos, surgical reduction is commonly required. This article reports a retrospective series of 5 blow-out fracture cases that had unusual nerve injuries after reduction operations. We represents the clinical experiences about treatment process and follow-up. Methods: From January 2000 to August 2009, we treated total 705 blow-out fracture patients. Among them, there were 5 patients (0.71%) who suffered from postoperative neurologic complications. In all patients, the surgery was performed with open reduction with insertion of $Medpor^{(R)}$. Clinical symptoms and signs were a little different from each other. Results: In case 1, the diagnosis was oculomotor nerve palsy. The diagnosis of the case 2 was superior orbital fissure syndrome, case 3 was abducens nerve palsy, and case 4 was idiopathic supraorbital nerve injury. The last case 5 was diagnosed as optic neuropathy. Most of the causes were extended fracture, especially accompanied with medial and inferomedial orbital blow-out fracture. Extensive dissection and eyeball swelling, and over-retraction by assistants were also one of the causes. Immediately, we performed reexploration procedure to remove hematomas, decompress and check the incarceration. After that, we checked VEP (visual evoked potential), visual field test, electromyogram. With ophthalmologic test and followup CT, we can rule out the orbital apex syndrome. We gave $Salon^{(R)}$ (methylprednisolone, Hanlim pharmaceuticals) 500 mg twice a day for 3 days and let them bed rest. After that, we were tapering the high dose steroid with $Methylon^{(R)}$ (methylprednisolon 4 mg, Kunwha pharmaceuticals) 20 mg three times a day. Usually, it takes 1.2 months to recover from the nerve injury. Conclusion: According to the extent of nerve injury after the surgery of orbital blow-out fracture, the clinical symptoms were different. The most important point is to decide quickly whether the optic nerve injury occurred or not. Therefore, it is necess is to diagnose the nerve injury immediately, perform reexploration for decompression and use corticosteroid adequately. In other words, the early diagnosis and treatment is most important.

Backgrounds and Objectives : Most patients with neck schwannomas are asymptomatic. Surgical management of neck schwannomas could cause various complications. The aim of this study is to evaluate the necessity of surgical management in all of the neck schwannoma patients. Material and Methods : Thirty-four patients diagnosed and undergone surgical management as neck schwannomas and 30 patients diagnosed and observed closely by OPD base from 1996 to 2005 were included. The medical records were reviewed retrospectively. Results : In surgical management group, mean age was 39.3 years and mean size of tumors was 4.4cm. Twenty-five patients had their tumors at parapharyngeal space, 2 at anterior neck and 7 at lateral neck. Nerves of origin were vagus nerve in 12 patients, cervical sympathetic chain in 11. Presenting symptoms were neck mass in 22 patients and no symptom in 9. On the other hand, in close observation group, mean age was 47.1 years and mean size of tumor was 3.7cm. Seventeen patients had their tumors at parapharyngeal space, 5 at anterior neck and 8 at lateral neck. Presenting symptoms were neck mass in 13 patients and no symptom in 13. There were no patients with neurologic complications. Mean follow-up duration was 38.2 months and there were only 2 patients whose size of tumors was increased and no patients who had newly emerged symptoms. Conclusion : Neck schwannomas grows slowly, has little chance of malignant transformation, but can complicate serious problems after surgical management. Therefore close observation could be considered in many asymptomatic patients.

Objective : The inappropriate or excessive apoptosis has been known to be associated with neurodegenerative disorders including intracranial hemorrhage(ICH). Paeoniae radix, in traditional Korean medicine, has played its role as blood­nourisher and yin-astringent. In the present study, the effect of Paeoniae radix on the inhibition of neurodegeneration in the brain of rats after artificial ICH and on the resulting apoptosis was investigated. Methods : 30 rats were divided into 6 equal groups ; the sham-operation group, the hemorrhage-induction group, the hemorrhage-induction with 10, 50, 100, and 200 mg/kg Paeoniae radix-treated group, respectively. Stereotactic surgery was performed and collagenase was infused to induce ICH in the region of CA1 of hippocampus of rats. The sham group took only saline infusion. For 7 days after the surgery, 4 testing groups had intraperitoneal injections of Paeoniae radix extract. The step-down inhibitory avoidance task, measurement of neurodegeneration degree in the CA1 region of the hippocampus, and detection of caspase-3 and newly generated cells in the dentate gyrus were done after animal sacrifice. Results : Rats receiving Paeoniae radix extract showed increased latency time in the inhibitory avoidance task. The extension of neuron-deprived areas in the CA1 region was significantly suppressed in the Paeonia treated groups. Also expressions of caspase-3 in the CA1 region and cortex were significantly inhibited in the Paeonia treated groups. The cell proliferation was evaluated by means of BrdU methods and proved to be decreased in the Paeonia treated groups. Conclusion : These results suggest that Paeoniae radix has potential to suppress short-tenn memory loss after devastating neurologic accidents. Also it was proved that Paeoniae radix has a neuroprotective effect and alleviates central nervous complications following intracerebral hemorrhage. Furthermore, it may imply that this medicinal plant can be widely used for vascular dementia and other neurodegenerative disorders.

This study was aimed at furnishing the data of Naso-orbito-ethmoidal fractures and aiding treatmenting Naso-orbito-ethmoidal fractures A 5-year review of Naso-orbito-ethmoidal fractures and concomitant injuries is presented. The patients were treated in the Dept. of Oral and Maxillofacial Surgery of Wankwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The results were as followes: Male predominated over female by a ratio of 4.6 : 1. The most common reasons is traffic accident(88.2%). The elapsed time from injury to operation is average 9.2 days, and the mean admission days were 79 days and removal of plates were average 217.3 days. The most associated facial bone fractures is Zygomatico-Maxillary complex fracture(20%). Associated injuries were neurologic injury(29.4%), orthopedic injury(23.5%), opthalmologic injury(17.6%), body injury(5.8%), neuropsychologic injury(5.8%) and otolaryngologic injury(5.8%) in this order. The most injured teeth were upper and lower incisors. The intubation methods for surgery were orotracheal(29.57%), submental(29.5%), and nasotracheal technique(41%). Most patients had complications, that were post-traumatic telecanthus, nasal depression, scar formation. This results suggest that early diagnosis and treatment is prerequisits to satisfactory result. Aggressive management of NOE fracture with direct or bicoronal exposure with aid of CT is now an accepted norm.

Background: The most definitive diagnosis of neck pain caused by facet joints can be obtained through cervical medial branch blocks (CMBBs). However, intravascular injections need to be carefully monitored, as they can increase the risk of false-negative blocks when diagnosing cervical facet joint syndrome. In addition, intravascular injections can cause neurologic deficits such as spinal infarction or cerebral infarction. Digital subtraction angiography (DSA) is a radiological technique that can be used to clearly visualize the blood vessels from surrounding bones or dense soft tissues. The purpose of this study was to compare the rate of detection of intravascular injections during CMBBs using DSA and static images obtained through conventional fluoroscopy. Methods: Seventy-two patients were included, and a total of 178 CMBBs were performed. The respective incidences of intravascular injections during CMBBs using DSA and static images from conventional fluoroscopy were measured. Results: A total of 178 CMBBs were performed on 72 patients. All cases of intravascular injections evidenced by the static images were detected by the DSAs. The detection rate of intravascular injections was higher from DSA images than from static images (10.7% vs. 1.7%, P < 0.001). Conclusions: According to these findings, the use of DSA can improve the detection rate of intravascular injections during CMBBs. The use of DSA may therefore lead to an increase in the diagnostic and therapeutic value of CMBBs. In addition, it can decrease the incidence of potential side effects during CMBBs.
