IVRO is a popular procedure to setback prognathic mandible. But guided functional physiotherapy after IVRO is the most important factor to get successful result, because there have been some concerns over an openbite tendency following this procedure. The purpose of this study is to evaluate the early adaptability to fuctional phsiotherapy and early openbite tendency associated with the kinds of surgery performed. The study was performed in fifty patients who had received bilateral IVRO from 1993 to 1994. After two weeks of maxillomandibular fixation(MMF), active physiotherapy was carried out according to Park's protocol and detail of openbite tendency was checked. We recorded the number of days for physiotherapy to analzye the adaptability in early physiotherapy until there was no more openbite tendency. The following results were obtained. 1. The adaptability in early physiotherapy to prevent openbite tendency following IVRO was more favorable in two-jaw surgery group than one-jaw surgery group.(p<0.005) 2. The adaptability in early physiotherapy was more favorable in lesser mandibular setback group than larger setback group, but there was no statistical significance. (p<0.05). 3. The adaptability in early physiotherapy was more favorable in posterior impaction group than non-posterior impaction group, but there was no statistical significance.(p<0.05). 4. The cases which MMF was applied again because of the strong openbite tendency were more plentiful in one-jaw surgery group than in two-jaw surgery group. 5. First two or three days after releasing of maxillomandibular fixation might be the critical period to prevent anterior openbite tendency, and if the partient shows strong openbite tendency during this period, 4-5 days of reapplication of MMF was enough to prevent openbite tendency .

Fracture of the vertebral end plate in the lumbar spine has been reported as a rare lesion occurring in the adolescent period. It is characterized by variable degrees of sign and symtom related to the degree of block on myelogram and the level of end plate fracture. Trauma or strenuous sport activity seems to play an improtant role in the production of fracture of vertebral body in the adolescent period. We experienced three cases of fracture of lower lumbar vertebral end plate in teenaged patients, two males and one female. Two patients showed upper end plate fracture with severe neurologic deficit on the involved root level and a strong positive on straight leg raising test, and one patient showed lower end plate fracture with slight neurologic deficit. Two patients with upper end plate fracture were treated with partial laminectomy with removal of fracture fragment and one patient with lower end plate fracture was treated with bilateral laminectomy and posterolateral fusion. The method of treatment will depend upon the type of fracture and the degree of neurologic symptoms. We obtained satisfactory results with posterior decompressive laminectomy and removal of fracture fragment with or without fusion.

Rotatory Instability of the permitting abnormal external totation of the tibia on the femur is the result af forced abduction of the flexed knee and external rotation of the tibia. The basic lesion is a tear in the medlal capsular ligament. The authors have reported clinical study in 40 patients with medial collateral ligament injuries who were treated by operative methods in the Orthopedic Department at the Taegu Presbyterian Hospital from January 1973 to Octdber 1979. of 40 patients, pes anserinus transplantation was performed on 15 patients and direct repair on 25 patients. The results are as followings: 1. All the patients were seen with a complete rupture of the medial collateral ligament and of these 45% had rupture of the femoral attachement. 2. Exellent to good result were more often obtained in recent injuries of less than 2 weeks rather than those in older Injuries. 3. Exellent to good result were more often obtained in the groups of Pes Anserinus tranplantation than the groups of direct repair. 4. In all cases of groups of pes anserinus transplantation, permanent sensory palsy af the patellar branches of the saphenous nerve was present due to the location of the surgical incision.

Arteriovenous mafformation(AVM) of female pelvic organ is a rare disease of unknown cause. The authors' report a case of pelvic AVM which was incidentally found during US examination of the patient with choriocarcinoma after chemotherapy. The real-time sonography revealed several cystic lesions around the uterus with adjacent dilated tortuous vessels. The color Doppler sonography depicted abundant blood flow mixed with red and blue colors within the cystic lesions and rapid turbulent systolic and diastolic flows. CT showed well-enhancing round vascular lesions with elongated vessels in the pelvis, and MRI depicted signal-void cystic lesions on both T1 and T2 weighted images with small portions of high intensity within the lesions on T2 weighted image. The angiography revealed pelvic AVM fed by tortuous uterine and vaginal arteries with a dilated draining vein

PURPOSE: Results of 181 percutaneous needle aspiration biopsies performed with an 18-gauge needle during a period of 3 years were analyzed to determine efficacy and safety of the procedure. MATERIALS AND METHODS: Biposies were performed in patients that could not be diagnosed by bronchoscopy or sputum cytology. The biopsy procedure with 18-gauge Crown needle was guided by fiuoroscopy. The biopsy specimen placed in 10% formalin solution were histologically confirmed. RESULTS: In 160 patients(89%), the positive diagnosis was made by percutaneous needle aspiration biopsy. There were 153 lung lesions(120 malignant and 33 benign lesions) and 7 mediastinal lesions. the diagnostic accuracy of malignant and benign disease was 91% and 80% respectively. Complications included pneumothorax(n=11) and hemothorax(n=l):six of them required treatment with chest tube and the remainder showed spontaneous resporption. CONCLUSION: PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions.

Five cases of histologically proven polymorphic reticulosis were examined with computed tomography(CT). CT findings were mucosal thickening along the septal and lateral walls of the nasal cavities(n=4), obliteration of the contour of the nasopharynx(n=4), involvement of the paranasal sinuses (n=2), destruction of the nasal septum and/or sinus walls(n=3) and mass in the palate, tonsil or neck (n=1). CT examination was helpful in determining the extent of the disease in the nasal cavity and paranasal sinuses. However, lesions in the palate and tonsils could not be easily evaluated with CT. CT findings of polymorphic reticulosis are nonspecific and granulomatous diseases may show similar CT findings.
