Objective : Surgery for the microvascular decompression is mostly concerned with injury to the cranial nerves or brain stem by cerebellar retraction. Intraopeartive brain stem auditory evoked potentials(BAEPs) has been continuously monitored on surgery to evaluate the extent of injury, recovery of the nerves and prognosis. Methods : Of the 161 cases of CP angle surgery from Feb. 1996 to Apr. 1998, 103 cases were monitored during operation. Thirty five patients who had undergone similar surgery were selected and evaluated ; 23 patients were monitored and 12 were not during surgery. If monitor showed more than 0.5 mSec delay of latency, surgeon was given a warning not to retract brain any more. If more than 1mSec delay, surgeon was informed to stop surgery and wait for the returning of evoked potentials. The level of amplitudes and delay of latencies during the initial stage of operation, opening the dura, insertion of teflon patches, and closing the dura and recovery were then compared. Resuls : Twenty patients were male and 15 were female. Their average age was 50.26 years. Mean amplitude during the initial stage of operation was $0.60{\pm}0.25mV$, at opening the dura $0.56{\pm}0.26$, after teflon patches insertion $0.49{\pm}0.20$, and after closure of dura $0.47{\pm}0.28mV$. Mean latency during the early stage of operation was $6.08{\pm}0.67mSec$, at opening of dura $6.38{\pm}0.55$, insertion of teflon $6.97{\pm}0.59$, and closing the dura $6.17{\pm}0.54$. There was statistical significance in the difference of amplitudes between each procedures, and in the difference of latencies. For the complete recovery of amplitude and latency, it usually took average 5.65 minutes(0-20 min). In monitored group, only one patient required more than 20 minutes to recover and suffered from hearing disturbance after surgery. Others were recovered within 10 minutes without complications. However, 4 out of 12 patients who were not monitored showed hearing disturbance, and 1 patient had temporary facial palsy and dizziness(p＝0.000). Conclusion : The results indicate that continuous intraoperative monitoring of BAEPs during CP angle surgery is seen mandatory procedure to prevent operative complications.

Objectives : The management of massive brain swelling remains an unsolved problem in neurosurgical field. Despite newly developed medical and pharmacological therapy, the mortality and morbidity due to massive brain swelling remains high. According to many recent reports, surgical decompression with dura expansion is superior to medical management in patients with massive brain swelling. We performed surgical treatment on the first line of treatment, and followed medical management in case with refractory increased intracranial pressure(ICP). To show the quantitative effect of decompressive surgery on the intracranial pressure, we performed ventricular puncture and checked the ventricular ICP continuously during the decompressive surgery and postoperative period. Materials and Methods : Fifty-one patients with massive brain swelling, undergoing bilateral decompressive craniectomy with dura expansion, were studied in this study. In all patients, ventricular puncture was performed at Kocher's point on the opposite side of massive brain swelling. The ventricular pressure was monitored continuously, during the bilateral decompression procedures and postoperative period. Results : The initial ventricular ICP were varied from 13mmHg to 112mmHg. Immediately after the bilateral craniectomy, mean ventricular ICP decreased to $53.1{\pm}15.8%$ of the initial ICP(ranges from 5mmHg to 87mmHg). Dura opening decreased mean ICP by additional 36.7% and made the ventricular pressure $16.4{\pm}10.5%$ of the initial pressure (ranges from 0mmHg to 28mmHg). Postoperatively, ventricular pressure was lowered to $20.2{\pm}22.6%$(ranged from 0mmHg to 62.3mmHg) of the initial ICP. The ventricular ICP value during the first 24 hours after decompressive surgery was found to be an important prognostic factor. If ICP was over 35mmHg, the mortality was 100% instead of additional medical(barbiturate coma therapy and hypothermia) treatments. Conclusion : Bilateral decompression with dura expansion is considered an effective therapeutic modality in ICP control. To obtain favorable clinical outcome in patients with massive brain swelling, early decision making on surgical management and proper patient selection are mandatory.

Objective : Thoracolumbar junction is second most common level of injury next to cervical spine. The object of this study is to study the usefulness of surgical titanium mesh instead of bone graft, as well as to evaluate the correction of spinal deformity and safety of early ambulation in patients with injury at thoracolumbar junction. Patients and Methods : This review included 51 patients who were operated from July 1994 to December 1997. The injured spine is considered to be unstable, if it shows involvement of two or more columns, translatory displacement more than 3.5mm, decrease more than 35% in height of vertebral body and progression of malalignment in serial X-ray. The decision to operate was determined by (1) compression of spinal cord or cauda eguina, (2) unstable fracture, (3) malalignment and (4) fracture dislocation. The procedure consisted of anterior decompression through corpectomy and internal fixation with anterior instrument and surgical titanium mesh which was impacted with gathered bone chip from corpectomy. Results : Fifty-one patients were followed up for at least 12 months. The main causes of injury were fall and vehicle accident. The twelfth thoracic and the first and the second lumbar vertebrae were frequently involved. Complete neural decompression was possible under direct vision in all cases. Kyphotic angulation occurred in a patient. Radiologic evaluation showed correction of deformity and no distortion or loosening of surgical titanium mesh with satisfactory fixation postoperatively. Conclusions : We could obtain neurological improvement, relief of pain, immediate stabilization and early return to normal activities postoperatively. Based on these results, authors recommend anterior decompression and internal fixation with surgical titanium mesh in thoracolumbar unstable spine injuries.

Purpose: The aim of this study is to present a retrospective review of patients who had a sudden onset of facial palsy after trauma and who underwent facial nerve decompression. Methods: The cases of 25 patients who had traumatic facial palsy were reviewed. Facial nerve function was graded according to the House-Brackmann grading scale. According to facial nerve decompression, patients were categorized into the surgical (decompression) group, with 7 patients in the early decompression subgroup and 2 patients in the late decompression subgroup, and the conservative group(16 patients). Results: The facial nerve decompression group included 8 males and 1 female, aged 2 to 86 years old, with a mean age of 40.8. In early facial nerve decompression subgroup, facial palsy was H-B grade I to III in 6 cases (66.7%); H-B grade IV was observed in 1 case(11.1%). In late facial nerve decompression subgroup, 1 patient (11.1%) had no improvement, and the other patient(11.1%) improved to H-B grade III from H-B grade V. A comparison of patients who underwent surgery within 2 weeks to those who underwent surgery 2 weeks later did not show any significant difference in improvement of H-B grades (p>0.05). The conservative management group included 15 males and 1 female, aged 6 to 66 years old, with a mean age of 36. At the last follow up, 15 patients showed H-B grades of I to III(93.7%), and only 1 patient had an H-B grade of IV(6.3%). Conclusion: Generally, we assume that early facial nerve decompression can lead to some recovery from traumatic facial palsy, but a prospective controlled study should and will be prepared to compare of conservative treatment to late decompression.

악관절 동통은 여러 가지 원인에 의해 발생하는 것으로서 동통을 호소하는 환자에서 Bone SPECT의 유용성을 알아보았다. 악관절 동통을 호소하여 Bone SPECT를 시행한 34명을 대상으로 하였으며 모든 환자에서 단순 촬영, planar 골스캔, Bone SPECT를 시행하였다. Bone SPECT에서 동위원소의 섭취 증가 정도에 따라 3가지로 분류하였다. Grade 0은 정상, Grade I은 후두골과 비슷한 섭취 증가, Grade II는 상악동과 비슷한 섭취 증가가 있는 것으로 정하여 각각 섭취 증가 정도에 따라 환자의 임상 증상과 치료 방법을 비교 분석했다. 34예중 27예 (80%)에서 악관절 Bone SPECT 시행시 섭취 증가가 있었고, 이중 21예 (78%)에서 하악과두에 섭취 증가가 있었고 나머지 6예 (22%)에서 하악궁과 상악궁에 섭취가 있었는데 이들은 치주질환으로 확인되었다. 총 34예중 Grade 0인 7예 (20%)에서는 관절 잡음이 3예 있었고 4예에서 약물 치료로 증상이 호전되었고 나머지 3예에서 치료 없이 증상이 호전되었다. Grade I 인 4예(12%)에서는 관절잡음이 3예 있었고 모두 약뭍 치료로 증상이 호전되었다. Grade II 23예(68%)중 관절 잡음은 7예 있었고 14예에서 약물치료 및 관절천자와 같은 감압술을 병행하여 증상이 호전되었다. 6예에서는 치주 치료로 증상이 호전되었다. 총 34예중 평면 골스캔에서는 11예(32%)에서 섭취 증가가 있었다. 단순 촬영에서는 16예(47%)에서 관절내강 협소 혹은 팽대, 골리란, 관절운동 제한 등이 관찰되었다. one SPECT는 악관절 동통 환자에서 유용하게 사용할 수 있는 진단적 방법이며, 치료방법을 결정하는 데 도움이 되었다. 동위원소 섭취 증가가 많을 수록 환자 치료에 보다 적극적인 치료를 필요로 하였으나 임상 증상과 동위원소 섭취증가는 밀접한 관계는 없었다.
