Skull base surgery has developed through the evolution of imaging, anatomic research, surgical approach and reconstructive techiques. The basic disciplines of approaching skull base lesions are to provide direct vision, minimize brain retraction, allow excellent exposure and minimal blood loss. Although many advantages listed above are reported, objective long-term follow up results about post-operative complications of this procedures were not introduced. This study was designed to review the complications of skull base approach that we experienced 43 cases by a team approach with neurosurgery-supraorbital rim osteotomy, orbitozygomatic osteotomy, orbitozygom aticoglen-oidotomy, orbitozygomaticoglenoidocondylotomy, and transfrontonasomaxillary osteotomy-through objective evalutation criteria. The result of this study demonstrated that the type of complications were consisted with perioperative infection (5 cases), subdural empyema (1 case), CSF leakage(1 case), hematoma (1 case), meningitis (3 cases), ophthalmic nerve injury (1 case),facial nerve injury (2 cases), T-M joint problem ( 2 cases), & enophthalmos ( 2cases). In conclusion, after performing the different skull base approaches, we analyzed several complications of the above procedures. We analyzed with the purpose of preventing complications in the next skull base approach.

Krukenberg tumor, which can account for 30-40% of metastatic cancers to the ovaries, arises in the ovarian stroma and is usually metastatic from the gastrointestinal tract, especially from the stomach. The pathognomonic feature is the presence of signet ring cells, which may be arranged in acini or appear as individual cells. We experienced a Krukenberg tumor which was bilateral and associated with left ovarian dermoid cyst. This patient was treated for a primary gastric carcinoma(Stage II) about 3 years ago. After bilateral salpingoophorectomy, she received adjuvant chemotherapy. But, she died about fow months after operation.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

A 2-month-old Korean boy presented with a solitary papule on the cheek which was noted at birth. Histopathologic findings were consistent with angiofibroma of fibrous papule of the face (FPF). FPF is known to affect adults, and congenital occurrence has not been reported to the best of our knowledge. We report a case of congenital FPF which showed a facial papule clinically and an angiofibroma histologically.

We performed an in vitro study to determine the effects of ultra high molecular weight polyethylene (UHMWPE) particles on the cell proliferation, matrix synthesis(type I collagen mRNA), and cytokines production(interleukin-lbeta and prostaglandin E2) of MG63 osteoblastlike cells. UHMWPE wear particles were isolated from osteolysis tissue of 8 patients during revision hip arthroplasties. Sub-micron UHMWPE powders were also isolated from fabricated virgin UHMWPE powders. Group I (control culture) contained no UHMWPE particles. In group II andIII, the UHMWPE wear particles and the UHMWPE powders were added to cultures of MG63 osteoblastlike cells with the different concentration of 0.2mg/ml, 0.02mg/ml, 0.002mg/ml, and 0.0002mg/ml. The average diameter of the retrieved UHMWPE particles was 0.4micrometa(ranged, 0.1 to 1.4 micrometa), and that of the fabricated UHMWPE powders was 0.6micrometa(ranged, 0.1 to 2.3micrometa). In group II and III, the UHMWPE particles induced an increase in osteoblastlike cell growth(p<0.05) but they inhibited the expression of type I collagen mRNA in a dose dependent manner(p<0.05). MG63 osteoblastlike cells exhibited a dose-dependent release of interleukin-1beta(IL-1beta) and prostaglandin E2(PGE2) in response to the exposure to the UHMWPE particles(p<0.05). There were no differences in the cell proliferation, the expression of type I collagen mRNA, and the release of PGE2 between the UHMWPE wear particles and the UHMWPE powders groups(p>0.05). The release of IL-lbeta was higher in group II than in group III(p<0.05). These data support the hypothesis that direct suppression and cytokines release of MG63 osteoblastlike cells by UHMWPE particles may play a role in particle-mediated osteolysis.

Skull base surgery has developed through the evolution of imaging, anatomic research, surgical approach and reconstructive techniques. The basic disciplines of approaching skull base lesions are provide direct vision, minimizing brain retraction, excellent exposure and minimal blood loss. The focus of this report is to review the advantages of skull base approach in our cases and suggest some indications. We experienced 20 cases of skull base surgery by a team approach consisting of a neurosurgeon and plastic surgeon. The surgical approach were supraorbital osteotomy(5 case), orbitozygomatic osteotomy(8 case), orbitozygomaticoglenoid osteotomy (5 case ) and orbitozygomaticoglenoidocondylar osteotomy (2 case). In our experience, these approaches provided excellent exposure of the lesion, direct access to lesions and minimal brain retraction thereby better outcome.

Reconstruction of extensive soft tissue defect of the head and neck after or resection or injury has improved with advances in surgical techniques. Traditional local flap techniques are not easy to reconstruct the extensive soft tissue defects and irradiated or contaminated recipient beds. Then musculocutaneous flaps such as pectoralis major flap, trapezius flap, latissimus dorsi flap and sternocleidomastoid flap have been performed. These musculocutaneous flaps are effective in resurfacing the neck and lower face, for example, mandibular area but difficult to reconstruct the upper face and scalp and the result is poor. Other alternative flap used to cover this area is free flap, but this flap has many limitation too and therefore reconstructive surgeons have attempted to develop new flaps. There are three distinct musculocutaneous flaps, the superior, the lateral island, and the lower island flaps, that can be harvested from the trapezius muscle that are used in head and neck reconstruction. The lower trapezius musculocutaneous flap provides a long paddle of thin, pliable skin and muscle and offers the long are of rotation and thus the greater versatility of the three types of trapezius flaps. But this lower trapezius musculocutaneous flap has may problems to reconstruct the upper part of face and scalp by traditional method and has used mainly to resurface the neck and lower face. Thus, authors modified the procedure of lower trapezius flap and tried to reconstruct the upper part of face and scalp. The modification is that during the dissection, the trapezius muscle must be totally mobilized and the dorsal scapular artery must be preserved. By this procedure, blood flow can circulate effectively to the distal portion of flap and then modified flap has greater are of rotation and reliably reach higher portion of face and scalp. The operative results me that among the eight cases performed by modified lower trapezius musculocutaneouas flap, seven were reconstructed successfully, and remaining one presented partial flap necrosis and secondary procedure was needed. The functional defecits of donor site were minimal in all cases.

Plasma col1 leukemia with motility-related morphological behavior is rarely studied. The plasma cells have variable degrees of cytoplasmic morphologies as dairy Projections, long extensions and pseudopods. These morphological evidences show the papa bility of wide spread and dissemination of disease itself. We present a case of a 38 year old woman who had back pain for 4 months and was diagnosed as a solitary plasmacytoma of the third lumbar vertebra. In spite of resection of the tumor and chemotherapy, the plasmacytoma was disseminated into both breasts and ovaries within less than a year. On her blood examination, we counted 34% of plasma cells in peripheral blood and 91.6% of plasma cells in bone marrow aspiration. Most of them resealed hairy projections and pseudopods of the cytoplasm.

Cesarean hysterectomy remains a necessary procedure for life saving during intractable obstetric hemorrhage. The procedure itself is usually associated with considerable perioperative morbidity, especially when performed under emergency conditions. In this study, the outcomes of 15 cases of cesarean hysterectomy performed at Catholic university of Taegu-Hyosung hospital for 5 years from January, 1993 to December, 1997 were reviewed. There were 22,251 deliveries during this period, cesarean hysterectomy was performed in 13 of 5,753 cesarean section(0.22%) and in 2 of 16,698 vaginal deliveries(0.12%), so more frequently after cesarean section than vaginal deliveries. The age of patients varied from 23 to 39 years old. The higher the age of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of emergency cesarean hysterectomy was in uterine atony(53.3%), followed by placental disorders(33.3%), uterine rupture(6.7%), and uterine myoma with pregnancy (6.7%). All patients who had cesarean hysterectomy received transfusion from 3 pints to 13 pints. In aspect of fetal outcomes, live birth were 12 cases(80%), one case was fetal death in utero(6.6%), 2 infants were dead during the early neonatal period(13.3%) due to prematurity and RDS (respiratory distress syndrome), so the perinatal mortality rate was 20.0%. The postoperative complications were wound disruption, hematoma, febrile morbidity and disseminated intravascular coagulopathy.
