Vestibular neurectomy is known as an effective procedure in the management of intractable peripheral vertigo from Meniere's disease and other episodic peripheral vertigo disorders. Various approaches have been developed for selectively sectioning the vestibular nerve, in order to preserve hearing and avoid facial nerve injury. Vestibular neurectomy is performed in two patients with Meniere's disease to control intractable episodic vertigo through retrolabyrinthine approach. Vertigo was improved with preserving their hearing. We report the surgical technique and advantages of retrolabyrinthine vestibular neurectomy in the treatment of vertigo.

Infectious process involves infrequently the posterior compartment of the vertebra. Three cases of such condition are experienced at the Dept. of Orthopedic Surgery, Seoul National University during the period of August 1962 to June 1971 Two of three cases were from pyogenic infection invoIving the spinous process of third and fourth lumbar vertebra respectively, one of which was complicated by formation of paraspinal abscess and both were treated with total laminectomy of the involved vertebrae. Thee third case was tuberculosis on the transverse process of first thoracic vertebra which was accompanied by irritating sign of left ulnar nerve, and was treated with transversectomy and partial laminectomy. Excellent results were obtained without recurrence and no deformity nor instability of the spine developed postoperativeIy.

Fat Embolism is a rare complication of multiple long bone fracture or extensive soft tissue injury. The pathogenesis of fat embolism has been poorly understood and still its definite pathogenesis, diagnosis and treatment were not fully established. Recently fat embolism considered as a post traumatic respiratory failure. Monitoring of blood gas is required for early diagnosis and respiratory supportive treatment with continued minitoring is necessary until resolution. Fifteen cases of fat embolism treated at from September 1979 to October 1981 Eul Ji General Hospital were clinically analized. Among the fifteen cases, fourteen were recovered without sequalae and one was expired ten days after trauma.

OBJECTIVE: The purposes of this study are to compare imaging features with operative findings and to determine significance of imaging studies for early detection of craniosynostosis(CS). METHODS: Plain radiograph of skull and three-dimensional(3D) CT reconstruction were analyzed in 10 consecutive patients with CS to assess the presence and the extent of synostosis. The radiological findings were investigated and compared with operative findings. RESULTS: The locations of lesion were coronal suture in 6, sagittal suture in 3 and multiple sutures in one patient, and the age ranged 1 to 53 months(mean age: 17.4 months). Reconstructive procedures with or without advancement of supraorbital rim were performed in coronal CS patients and PI-procedures or synostectomy were done in sagittal CS patients. Radi-ological abnormalities such as sutural indistinctness or sclerosis, bony ridge, bossing and other bony deformities were nearly consistent with surgical findings. CONCLUSION: The interpretation of imaging study are very important for early detection of craniosynostosis, especially, the plain radiographs of skull. Also 3D CT imaging is helpful in diagnosis and surgical planing of craniosynostosis. There are no significant differences between imaging features and operative findings in CS patients.

OBJECTIVE: The authors report an analysis of clinical data including incidence, clinical manifestations, diagnostic tools and surgical treatment of neoplasms of scalp and calvarium in adults. METHODS: The clinical, radiological, and pathological records of 67 patients who underwent mass excision in scalp or skull at our department during recent five years were reviewed. RESULTS: The mean age was 43 years(range 16 to 85 years) and male to female ratio was 42 : 25. There were 62 scalp and five calvarial masses. Among scalp masses, there were 52 tumors, three vascular lesions, three inflammatory lesions and four miscellaneous lesions. The scalp tumors were composed of 44 benign lesions and nine malignant lesions. The most common type of scalp tumor was lipoma, followed by epidermoid and dermoid. The calvarial masses consisted of four osteomas and one eosinophilic granuloma. Surgical excision was carried out in all cases. CONCLUSION: Most scalp and calvarial masses are benign lesions, however, surgical excision seemed to be indicated in most cases for diagnosis and treatment.

OBJECTIVE: Allelic losses or loss of heterozygosity (LOH) at many chromosomal loci have been found in the cells of meningiomas. The objective of this study was to evaluate LOH at several loci of different chromosomes (1p32, 17p13, 7q21, 7q31, and 22q13) in different grades of meningiomas. METHODS: Forty surgical specimens were obtained and classified as benign, atypical, and anaplastic meningiomas. After DNA extraction, ten polymorphic microsatellite markers were used to detect LOH. Medical and surgical records, as well as pathologic findings, were reviewed retrospectively. RESULTS: LOH at 1p32 was detected in 24%, 60%, and 60% in benign, atypical, and anaplastic meningiomas, respectively. Whereas LOH at 7q21 was found in only one atypical meningioma. LOH at 7q31 was found in one benign meningioma and one atypical meningioma. LOH at 17p13 was detected in 4%, 40%, and 80% in benign, atypical, and anaplastic meningiomas, respectively. LOH at 22q13 was seen in 48%, 60%, and 60% in benign, atypical, and anaplastic meningiomas, respectively. LOH results at 1p32 and 17p13 showed statistically significant differences between benign and non-benign meningiomas. CONCLUSION: LOH at 1p32 and 17p13 showed a strong correlation with tumor progression. On the other hand, LOH at 7q21 and 7q31 may not contribute to the development of the meningiomas.

OBJECTIVE: Most of the studies that have described surgical procedures for moyamoya disease(MMD) have had the aim to improve the blood flow mainly in the middle cerebral artery(MCA) territory. The purpose of this study is to clarify the good indications for a multiple burrhole operation to treat MMD. METHODS: With the patient under local anesthesia, burrhole trephination with a diameter of 1.5 to 2cm at 3 to 5cm lateral to the midline was performed in a total of 18 hemispheres during 12 procedures. The burrholes were opened in the frontal lobe at 19 sites in 10 patients and in the parietal lobe at 22 sites in 12 patients. Revascularization through multiple burrholes and arachnoid openings was performed in 12 patients who suffered from MMD. RESULTS: As seen on the follow up angiograms, good revascularization was achieved in 27 of 41 burrholes, and mainly from the middle meningeal artery and then from the superficial temporal artery. The moyamoya vessels were decreased in four patients. The neovascularization covered 68.4% of the frontal lobe and 63.5% of the parietal lobe. Compared with the preoperative 99mTc-HMPAO-SPECT, 6 patients showed improvement of cerebral blood flow on the postoperative 99mTc-HMPAO-SPECT. Transient ischemic attack disappeared in three of the four patients who presented with this symptom, and the preoperative symptoms improved in both of the patients who presented with headache and cerebral infarction. CONCLUSIONS: A multiple burrhole operation is a simple technique. The results of our series suggest that the revascularization obtained for adult MMD patients who underwent a multiple burrhole operation is similar to that obtained with other indirect surgeries, but long term follow up studies are needed.
