Ten cases of unstable spine were treated with various surgical procedures under control of Halo apparatus and following results wen obtained. 1. Six cases of unstable cervical spine were treated with Halo apparatus and were able to obtain solid fusion for permanent stability. 2. Three cases of tuberculous kyphosis were corrected with halo-pelvic hoop on, and were able to obtain mean correction angle of 42 (65%) with little danger. 3. With halo on, staged operations such as anterior and posterior osteotomy, gradual distraction, anterior and posterior fusion of the spine for correcting deformity were carried out securely. 4. Average duration of halo application was eight weeks, no more twelve weeks, and there was no irreversible complication with halo apparatus per se.

The authors have reviewed 71 cases (70 patients) of the ankle fractures that were treated through the admission in Orthopedic Department, Paik Foundation Hospital, from June 1972 to April 1978. The average duration of the follow-up waa 15 months. The summary of the results were as follows; 1. Of the 71 cases, male was 54 cases and female 17 cases. The average age of the patients was 32. 2. The main cause of the injuries was traffic accident, and the other causes were sliding down and falling from a height, industrial accident, and sports injury in order. 3. By the classification of Lauge-Hansen, the pronation-external rotation and,supination-adduction types were commoner than the other types. 4. Open reduction was performed in 48 cases, and closed reduction in 23 cases. 5. The average duration of the cast immobilization after the closed reduction was 8 weeks, and that of the open reduction was 6 weeks. 6. The result of the treatment was better in those cases of the open reduction than that of, the closed reduction. 7. The good clinical results could be achieved by obtaining the anatomical position of the talus in the mortise and the reduction was achieved more satisfactorily when the key role of the lateral malleolus in complete reduction was well understood.

This study was undertaken to investigate the growth change of gonial angle and interrelationship between the growth change of gonial angle and IMPA in the longitudinal data from 7 years to 15 years. By analyzing the serial lateral cephalograms of 15 males and 18 females of 7 years old to 15 years old who had no abnomality in growth and development and no history of orthodontic treatment, the following conclusion were obtained. 1. Gonial angle gradually decreased with aging in 25 children and in 9 children increased or maintained. 2. There was a tendency that children who decreased gonial angle with aging showed gradual increase of IMPA and children who increased of maintained gonial angle with aging showed decrease of IMPA 3. There was a tendency that regardless of the change of gonial angle, interincisal angle decreased with aging.

PURPOSE: To compare 3D ultrasound (3D-US) with 2D ultrasound (2D-US) in terms of their usefulness and limitations in the diagnosis of breast masses. MATERIALS AND METHODS: We obtained 2D and 3D US images of 37 breast lesions present in 20 cases of fibroadenoma, nine of cancer, and eight of fibrocystic disease proven in a total of 26 cases [fibroadenoma (n=13), breast cancer (n=9), fibrocystic disease (n=4)] by histologic examination, and by clinical evaluation and clinical evaluation with sonographic imaging in eleven. When comparing 3D and 2D-US images we had no prior information regarding detection rate according to the size of lesions, whether or not internal and boundary echo patterns could be interpreted, accurate differentiation between tumorous and non-tumorous lesions, or the accuracy with which benign and malignant tumors could be differentiated. RESULTS: For lesions of 1 cm or less in diameter the detection rate of 3D-US was lower than that of 2D-US, but for lesions over 1 cm there was no difference between the two modalities. In fibroadenoma and breast cancer, 3D-US was more useful than 2D-US for the evaluation of both internal and boundary echo, but with fibrocystic disease and in the diagnosis of tumor/non-tumor, there was no significant difference. In breast cancer, however, 3D-US more accurately determined malignancy, and in fibroadenoma, because of the pseudospicule revealed by 3D-US, this modality was less exact in determining benignancy. CONCLUSION: In the evaluation of internal and boundary echo in breast mass diagnosis, 3D-US was more useful than its 2D counterpart. For lesions of 1 cm or less in diameter, however, the detection rate of 3D-US was low, and since in some benign cases a pseudospicule was apparent, the possibiliy of confusion with malignancy arose. For these reasons, the usefulness of 3D-US was limited.

This case presents a 34-year-old man who had a huge parasagittal meningioma. Initial treatment consisted of preoperative external carotid artery embolization and partial tumor resection. During the resection, we found that the tumor invaded the adjacent calvarium, and due to massive hemorrhage, total removal of the tumor was impossible. The patient was treated with intraoperative radiation therapy (IORT) (25 Gy via 16 MeV) as an adjunctive therapy. Eight months after IORT, we were able to remove the tumor completely without surgical difficulties. IORT can be considered an useful adjunctive therapy for the superficially located, huge, and highly vascular meningioma.

BACKGROUND: The cuff pressure (CP) of the laryngeal tube airway (LTA) increases during general anesthesia using nitrous oxide. However, there have been few studies on the relationship between CP and postoperative sore throat (POST). This study evaluated the efficacy of the CP on a POST on the recovery time and postoperative day. METHODS: Forty patients were divided into two groups, group M (n = 20) and group I (n = 20). In all patients, the CP was set to 65 cmH2O at the induction of anesthesia. In group M, the CP was maintained at 60-70 cmH2O during general anesthesia using N2O. However, in group I, the CP was allowed to increase. The CP was measured every 10 minutes during surgery in the two groups. The frequency and intensity (numerical rating scale of 0-100, NRS-101) of the sore throat was measured at recovery room (RR) and on postoperative day 1 (POD1). RESULTS: There was a significant increase in the CP in group I during general anesthesia and the CP was higher in group I than in group M (P < 0.05). The frequency of POST was higher in group I at RR (10% vs 70%) and POD1 (0% vs 35%) than in group M. In addition, the NRS-101 was higher in group I at RR and POD1 than in group M (P < 0.05). CONCLUSIONS: The CP of the LTA needs to be monitored and controlled during surgery in order to reduce POST.

Although the mortality has been reduced with aggressive approach, thyrotoxic storm or crisis is still a life-threatening condition and usually triggered by preeclampsia, placenta previa, congestive heart failure, infections and induction of labor during pregnancy. We report here a 28-year-old pregnant woman suspicious of placenta previa without a previous history of hyperthyroidism was admitted to the hospital with vaginal spotting and labor. After receiving a Cesarean section, thyrotoxic manifestations were developed and she became stable with antithyroid therapy. The second attack of thyrotoxic storm was presented after a thyroid ultrasonographic study. It appears that the vigorous examination of thyroid gland carries a significant risk of thyrotoxic crisis in poorly controlled hyperthyroidism.
