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 .

A giant abdominal aortic aneurysm (AAA) renders surgical treatment much more difficult by deforming the proximal infrarenal aortic neck (shortened length and disturbed angulation), by altering the iliac arteries (marked tortuosity and aneurysmal dilatation), and by displacing abdominal organs. Because the retroperitoneal rupture of giant AAA makes the mesentery more elongated and deformed, compromising its blood flow and thus increasing the risk of mesenteric ischemia such as colon ischemia. We describe here the surgical repair of a large infrarenal AAA with a ruptured huge left common iliac artery aneurysm of 13.5 cm in diameter, accompanied by colostomy due to colon ischemia which occurred during the operation. We discuss the pathophysiology and preventive strategy of colon ischemia during ruptured giant AAA repair.

The authors report the experience of twenty patients of transpedicular Zielke instrumentation after anatomical reduction of the spondylolisthesis. Anstomical reduction was done with the aid of temporary application of Harrington distraction rod, and the reduced segment was fixed with transpedicular Zielke instrumentation. And, anterior interbody fusion was supplemented in a single stage operation. Follow up period was between 13 to 25 months after operation with the average of 19 months. 1. The age of the patients was 38 years in average ranging from 11 to 61 years. 2. Types of the spondylolisthesis were spondylolytic type in 11 cases, degenerative type in 6 cases, dysplastic type in 1 case and pathologic type in 2 cases. 3. The level of the lesion were L5-Sl in 12 cases, L4-5 in 7 cases and L3-4 in 1 case. 4. Pre-operative clinical feature included low back pain in 95%, radiating pain in 65%, and neurological claudication in 45%. 5. The average percentage of slippage was changed from 24% preoperatively to 6% postoperatively and to 8% at the final follow up. The initial correction rate was 75% and the amount of correction loss during the follow up period was 11% in average. 6. Slip angle was changed from 3°preoperatively to −3°poetoperatively and to 0°at the end of follow up. In the 12 cases with local kyphosis, average slip angle of 14°preoperatively was improved to 2°postoperatively, and to 7°at the end of follow up. 7. Bony fusion was obtained in 19 cases within 4 to 6 months. 8. There were 2 cases of metal failure with considerable loss of reduction ; one patient with pathologic spondylolisthesie due to active tuberculous spondylitis required re-operation and another patient showed fusion eventually in the redisplaced position. Other complication included 1 transient dysuria, 1 ileus and 2 meralgia paresthetics. 9. Clinical symptoms were improved in 95%. Follow up result of the operation according to Gill's criteria were excellent 65%, good 25%, fair 5%, and poor 5%.

Optic nerve gliomas are uncommon, and they and derived from altrocyte or oligodendrocyte of the optic nerve. The peak incidence is from 2 to 6 years of age. In most cases, prognosis is good and it is usually developed unilaterally. Occasionally it involves bilateral optic nerve and then usually associated with neurofibrotnatosis. Among reports of optic nerve gliomas, the incidence of neurofibromatosis varies from 12% to 38%. We have experienced of a case of bilateral optic nerve glioma not associated with neurofibromatosis in a 6 year old female patient. So the literature of the optic nerve gliomas was briefly reviewed with clinical study.

Temporomandibular disorders arised from joint itself was caused by inflammation or mechanical irritation of the retrodiskal tissues. Histologic changes of the retrodiskal tissues of temporomandibular joint(TMJ) internal derangement, such as inflammatory cell infiltration, hyalinization, myxoid change, fatty change, arterial obliteration, and so on, were reported, but relationships between magnetic resonance imaging(MRI) findings and histologic findings of the retrodiskal tissue were few reported. The purpose of this study was to find histologic changes of the retrodiskal tissues for status of joint and joint effusion in MRI of the temporomandibular joint which had surgical treatment. Materials were surgically treated 52 temporomandibular joints with internal derangement or osteoarthritis in TMJ clinic, Yongdong Severance Hospital. All joints were confirmed by magnetic resonance T1-and T2-weighted imagings bofere surgery. Status of joint was categorized by normal position, disc displacement with reduction, disc displacement without reduction, disc displacement without reduction associated with osteoarthrosis using preoperative MR T1-weighted images. Magnetic resonance evidence of joint effusion was observed in T2-weighted images and classified by its amount; degree 0(not observed), degree 1(small amount), degree 2(moderate amount), degree 3(large amount). Histologic features were observed whether the retrodiskal tissue has inflammatory cell infiltration, myxoid change, hyalinization, chondroid metaplasia and arterial obliteration. The distribution of elastic fibers were also observed. The results were as follows; 1. Inflammatory cell infiltration was not observed in any retrodiskal tissues. 2. MRI findings such as status of joint and evidence of joint effusion did not have significant relationship with myxoid change, hyalinization, chondroid metaplasia, arterial obliteration of the retrodiskal tissues. 3. Hyalinization and chondroid metaplasia were found in 8 joints(15.4%) and 5 joints(9.6%). All of them were found in disc displacement without reduction and disc displacement without reduction associated with osteoarthrosis. 4. Arterial obliteration was observed more frequently in disc displacement without reduction(55.6%) than disc displacement without reduction associated with osteoarthrosis(28.6%). Further studies with proper controls and more materials will be necessary.

BACKGROUND: Generalized aggressive periodontitis (GAP) is a destructive periodontal disease that can develop in young age. Only a few cases of full mouth rehabilitation, using dental implants, have been reported in a patient with aggressive periodontitis. CASE DESCRIPTION: This clinical report describes the treatment procedures and results of full mouth rehabilitation in a patient with aggressive periodontitis. After all teeth were extracted, 6 implants were placed in the maxilla and mandible, respectively. Fixed detachable implant prostheses were made. The patient was satisfied with the final results. She was followed for 10 months postloading. CLINICAL IMPLICATION: For a long-term success, continuous maintenance care is critical, as the contributing factors of the disease (such as immune factors or periodontal pathogens) may not be controlled adequately.
