송중원,한기환,박성근,강진성 大韓成形外科學會 1991 Archives of Plastic Surgery Vol.18 No.2

본 교실에서는 전두사골 수막뇌류에 의한 안와격리증 2례는 두개내 접근으로 수막뇌류 절제술을 실시함과 동시에 두 개외 접근으로 안와내벽 및 외벽 절골술로써 교정하였으며 Saethre-Chotzen 후군에 의한 1례는 두개골 성형술과 U형 절골술로 교정하여 비교적 만족할 만한 결과를 얻을 수 있었기에 보고하는 바이다. The authors experienced two cases of mild hypertelorism with frontoethmoidal meningoencephalocele and one with Saethre-Chotzen syndrome. The first and second cases, which had nasofrontal and nasoethmoidal meningoencephalocele respectively, were corrected by resection of the meningoencephalocele, repair of the dura, and calvarial bone graft intracranially, and combined medial and lateral orbital wall osteotomy with augmentation rhinoplasty with calvarial bone grafts extracranially. To stabilize the orbital contents medially, a split osteotomy of the lateral orbital wall and interpositional bone graft were done in order to avoid step deformity of the lateral orbital rim. The third case, Saethre-Chotzen syndrome characterized brachycephaly, hypertelorism, ptosis of the eye lid, maxillary hypoplasia, lower set frontral hair line, and partial cutaneous syndactyly was corrected by a Modified Marchac technique for remodelling the forehead and a subcranial U-osteotomy for mild hypertelorism. Maxillary hypoplasia was corrected effectively by advancement on the medial portion of the U-shaped bony segment. Augmentaton rhinoplasty with calvarial bone graft and chip bone grafts on the anterior nasal spine was done simultaneously. A large amount of nasal bone grafts in two cases were absorbed, and then augmentation rhinoplasty using silicone implant was performed after 6 months, 12 months respectively. In mild hypertelorism with associated deformity, a extranial osteotomy with augmentation rhinoplasty and correction of associated deformities can offer good aesthetic results.

Background : Serum osteocalcin is synthesized by osteoblast and has been shown to be sensitive indicator of bone turnover inpatients with various metabolic bone disease. In renal osteodystrophy, serum osteocalcin is elevated due to decreased renal clearance and elevated level of PTH. This study was done to evaluate the usefulness of serum osteocalcin as a marker of bone metabolism and the correlation with other biochemical markers of bone metabolism. Methods : We measured serum osteocalcin, calcium, phosphorus, ALP(alkaline phosphatase) and PTH(parathyroid hormone) in 37 patients with end stage renal disease on hemodialysis. Osteocalcin was determined by radioimmunoassay and PTH was determined by radioimmunometric assay. Results : 1) The mean level of serum osteocalcin in ESRD patients was 233.8± 218.2ng/ml which was significantly higher than that of controls(p<0.0001). 2) The mean level of serum PTH in ESRD patients was 40.5± 43.8pg/ml was significantly higher than that of controls(p<0.005). 3) There was a significant positive correlation between the level of serum PTH, ALP and the level of serum osteocalcin in ESRD patients. 4) By using multiple regression, PTH is most reliable factor that affect to elevated level of serum osteocalcin ( beta coefficient = 0.687, Sig T<0.05). Conclusion : Serum osteocalcin as a marker of bone metabolism in ESRD patients is more useful than other biochemical marker such as serum calcium, phosphorus, ALP and PTH is a most reliable factor that affect to elevated level of serum osteocalin.

Authors report a case of one-stage transoral decompression and posterior fusion in rheumatoid atlantoaxial subluxation. A 63-year-old man developed a rheumatiod atlantoaxial subluxation with mild weakness of all extremities which developed relatively suddenly 3 months after the initial symptom of neck pain. Skeletal traction followed by transoral decompression and occipitocervical fusion was performed on the same day. Postoperative course has been uneventful and revealed favorable fusion state of occipito-atlanto-axis. The pertinent literature on theumatoid atlanto-axial subluxation is reviewed and discussed.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

PVC 및 Olefin계 Copolymer의 열안정성에 관한 연구(II) : 열안정 영향 인자 Thermal Stability Factor

Several structural factors which governs the thermal stability of poly(vinyl chloride) were investigated by IR and H¹-NMR spectroscopy. PVC-Olefin copolymers having diverse structure were prepared by same reaction conditions such as reaction temperature and comonomer composition. It was found that keto allyl groups in the polymer backbone which were formed through a side reaction show the most pronauncing effect. The content of keto allyl group appeared to increase with the relative amount of olefin comonomers. On the other hand, neither chain branching nor tecticity influenced the thermal stability of copolymer. Also, the content of double bond fromed at chain ends was unrelated to the thermal stability.

Although the zygomatic arch can be employed as a key landmark to the accurate alignment of a displaced zygoma fracture, it has been traditionally avoided because of the need for a bicoronal incision. Exposure of the zygomatic arch by means of the conventional bicoronal incision has several possible disadvantages, including an increased risk of blood loss, alopecia, loss of sensation posterior to the incision, and traction palsy of the facial nerve. Endoscopic-assisted exposure of a zygomatic arch can largely obviate the disadvantages of a bicoronal incision and yield this site accessible to reduction and internal fixation in the routine treatment of displaced zygoma fractures. 9 cases of endoscope-assisted open reduction of zygomatic arch fracture and 3 cases of internal fixation of a moderately displaced zygoma fracture are presented. To accomplish this technique, a rigid 4 mm, 30 degree down-angled endoscope, trocar and cannula, endoscopic forehead lift instrument were used. The postoperative courses were satisfactory with few complications. The use of endoscope in the treatment of zygoma reduction provided an expanded field of vision, direct manipulation of lesions, minimal postoperative scar. In particular, exposure and fixation of the zygomatic arch were performed without the need for a bicoronal incision.

To elucidate the incidences and the clinical characteristics of glomerular diseases in our hospital, we reviewed the clinical records and histological findings of the 117 cases, which were diagnosed as one of the glomerular disease in renal biospy for about 6 years since 1991. In these 117 cases, 74 cases (63.2 %) fell into primary glomerulonephritis(GN), 18 cases (15.4%) into secondary GN, 2 cases (1.7 %) into end stage kidney, 4 cases (3.4%) into tubulointerstitial disease and the biopsy samples were inadequate for diagnosis in 19 cases. In primary glomerular diseases, most common pathologic diagnosis was IgA nephropathy (36.5 %}, followed by minimal change nephrotic syndrome (29.7%). The incidence of IgA nephropathy would be increased if we had biopsied every asymptomatic urinary abnormality (AUA) patients. Systemic lupus erythematosus (SLE) . hepatitis B accounted for most of secondary GN in our cases. One case of progressive scleroderma was included in this secondary GN. Minimal change nephrotic syndrome (22 cases) was the most common cause of nephrotic syndrome, followed by membranous GN (9 cases) and IgA nephropathy (8 cases). 2 cases of primary amyloidosis were presented with nephrotic syndrome. Nephrotic syndrome as presenting symptom in our IgA nephropathy patients was higher than in other studies, which may be due to indication bias for renal biopsy. We suggest that renal biopsy should be done in adult nephrotic syndrome and in SLE, because various kind of glomerular diseases can develop nephrotic syndrome in adult, renal biopsy can affect the treatment and prognosis in each patients and renal biopsy also determines the extent of renal involvement in SLE on which the treatment depends. In AUA urinary patients, renal biopsy could be reserved for the patients who show declining of GFR or rising of proteinuria. Because IgA nephropathy account for most of AUA. and there is no specific treatment for IgA nephropathy, and renal biopsy in those cases is helpful in ruling out the patients who need no treatment.

Owing to the complexity of the deviated structures and the septal deformities accompanying the external nasal deformities, the complete correction of the deviated nose is regarded as a difficult one. The approach to the nasal bone and osteotomy in classic corrective rhinoplasty is almost blind technique, where the results depends on the feeling by surgeon's hand. To overcome these drawback, endoscopic-assisted corrective rhinoplasty and septoplasty performed for 8 cases of deviated nose between January 1996 and May 1997. Average follow-up period was 10 months. All patients were evaluated by symmetrical nasal pyramid, recurrence of the bony deflection and septal deviation. The postoperative courses were satisfactory in most of cases with few complications. It appears that endoscopic control during corrective rhinoplasty and septoplasty is a big step toward obtaining better results in bony and cartilage resection with extreme precision under monitor control and magnification. This technique is not an open approach but permits one to see more of the nasal skeleton and bony septum what is causing deformity, and the immediate effect of the corrective measures used. The use of endoscope in corrective rhinoplasty will provide expanded field of vision, direct manipulation of lesions, and better aesthetic an6 functional results.
