We have employed the external akeletal fixation devices, that is Hoffmann apparatus and Pin and Resin fixation method, for the treatment of 44 cases of long bone fractures from Dec. 1978 to Dec. 1981. The following are our impressins. 1. Hoffmann apparatus and Pin and Resin fixation method proved to be effective and useful measure for the management of fractures of long bones, particulary in cases of the open tibial fractures. 2. Employing the Hoffmann apparatus to the tibial model, the possible limit of correction of the fracture alignment was calculated. It was found that the average angle of correction of deformity can be managed up to 20 degrees in varus and valgus deformity, 70 degrees in anterior angulation, 40 degrees in posterior angulation and 70 degrees in rotation. 3. Pin and Resin fixation method is one of effective means in immobilization of long bones. It is simple to apply, easy to manipulate and inexpensive while offering fair fixation without much complications and therefore we recommend the method as the best alternative to expensive Hoffmann apparatus. 4. The complications of Hoffmann apparatus and Pin and Resin fixation method were pin tract infections and ankle stiffness which were generally minor and prevented by more careful aseptic technique and encouraging early joint motion.

Carotid cavernous sinus fistula is abnormal communication between the carotid artery and the cavernous sinus. It can be classified according to three criteria : 1) pathologically into spontaneous or traumatic ; 2) hemodynamically into high flow or low flow fistula ; 3) angiographically into direct or dural fistula. We studied the regional cerebral blood flow changes in traumatic carotid cavernous sinus fistula. Regional cerebral blood flow checked 7 times during trapping procedure. The results are as follows ; 1) regional cerebral blood flow decreased in normal side than in lesion side hemisphere in the state of carotid cavernous fistula. 2) After compression of lesion side common carotid artery over 10 minutes, cerebral blood flow increased in both side. 3) Cerebral blood flow decreased temporary after operation on both side but normalized 2 or 3 weeks later.

A series of 70 patients with chronic subdural hematoma, admitted to the Department of Neurosurgery of Kyung Hee University Hospital from Aug. 1, 1977 to July 31, 1982 is presented. The following results were obtained. 1) Males were more frequently involved than female with the ratio of 4.8 : 1. Peak age incidence was 6th and 7th decade. Bilateral subdural collections were only 4 cases and others were unilateral. 2) Older age(more than 50) had more frequently focal neurologic deficit such as hemiplegia, however younger age(less than 50) presented as increased intracranial pressure signs such as headache and vomiting. 3) The hematoma density of CT-scan on admission was hypertense, 3 cases(4.9%); mixed density, 20 cases(32.8%); isodense, 18 cases(29.8%); and hypodense, 20 cases(32.8%) respectively. 4) The operative method between simple burr hole drainage and craniotomy with membranectomy didn't affect the postoperative results. The operative mortality was 2.9%. 5) Follow-up CT scanning was performed in 32 patients, only 8 of them showed normal CT findings within one month after operation. One patient still showed remnant of hematoma on 50th postoperative day. 6) Osmolarities of the hematoma and systemic venous blood were measured simultaneously 10 times in 8 cases. Hematoma osmolarities were isosmolar 1, hyperosmolar 6 and hyposmolar 3 compared with systemic venous blood.

Using Xenon inhalation method, the authers measured the rCBF's within 24 hours before and after the operation of 4 AVM patients. We found the obliteration of the cerebral steal syndrome in all cases and the loss of initial shunt peak in 2 cases after excision of AVM. We discussed these hemodynamic changes in AVM and reviewed the literatures.

With Xenon gas inhalation method, the authors measured the rCBF from 14 AVM patients who were checked into the Neurosurgical Department of Kyung Hee Medical College. In nine of them, we detected the rCBF within 24 hours after operation ; in comparison with the clinical progress, we got the results as follows; 1) The amount of rCBF before operation was 62.9+/-12.7 in adjacent regions around the AVM, and 67.8+/-14.7 in the contralateral hemisphere. These values were lower than normal rCBF, undoubtedly demonstrating the development of cerebral steal phenomenon. 2) After total excision of AVM, the amount of rCBF was 77.5+/-20.7(11.6+/-21.5% increase) in adjacent regions around AVM, and 79.6+/-16.3(8.9+/-17.0% increase) in the contralateral hemisphere. As the cerebral steal phenomenon was disappeared, 80% of clinical symptoms and signs were restored, which showed the interrelation between the rCBF and clinical progress. 3) The measurement of rCBF by Xenon gas inhalation method does no harm to human body, and can be carried out with ease and safety. 4) It is thought that in the case if AVM patient, the measurement of rCBF by Xenon gas inhalation method is a good parameter for diagnosis and follow up of AVM's patients.

Spontaneous hematomyelia is an acute expanding lesion by the hemorrhage within the substance of the located primarily in the gray matter. It is necessary to have urgent operation to preserve the remainding cord function. We are reporting a rare case of spontaneous hematomyelia extending from T-8 to T-10 of unknown cause of which transverse symptoms have largely subsided after surgical evacuation of the liquefied hematoma.

A case of mucocele of the sphenoid sinus having diplopia and headache is presented. This rare disorder is benign and curable by simple intranasal procedure. But it is often misdiagnosed as malignant or pituitary tumor, and unnecessary treatment such as radiotherapy or craniotomy has been performed. We removed it by sublabidal trans-septal trans-sphenoidal approach without difficulties and postoperative complications.

We have experienced 480 cases of Cerebrovascular Disorder confirmed by C. T. Brain scan, who admitted to the Kyung hee Medical Center from January 1979 to December 1980. The authors have analyzed the clinical aspects of Cerebrovascular Disorder. The following results are obtained. 1) Intracranial hemorrhage group is more commoner than occlusive group. The sixth decade is most frequently involved. Male is more affected. 2) Headache is most frequent initial symptom and next sequence is paresis. 3) The prognosis is correlated with the initial consciousness level, initial CSF pressure and hematoma volume. 4) In the intracranial hemorrhage group, the prognosis is somewhat better in the operative cases than in the non-operative cases.

Subdural empyema is a neurosurgical emergency the mortality of which continues to be as high as 40% in modern reported series. It is also a curable lesion, and the outcome of treatment has been demonstrated to be directly related to the promptness of diagnosis and appropriate surgical drainage. Recently, we have operated upon two cases of intracranial subdural empyema secondary to acute facial furuncle and postoperative craniectomy. Reviewing these two cases and other literatures, we are going to describe about cases, symptoms and signs, and methods of diagnosis and treatment of subdural empyema.
