The concept and technique of using high-density porous polyethylene (HDPP), a nonresorbable synthetic material, for nasal
spreader grafts, are presented. This material is thought to be particularly useful in revision (secondary or tertiary) rhinoplasty,
in which internal valve collapse frequently is confronted and septal cartilage often is unavailable because it has been harvested
for spreader or other grafts. Sold as a thin plain sheet (0.85 × 38 × 50 mm) that can be cut to an appropriate size for spreader
grafts, HDPP is a ready-to-use material commercially available on the market. Because HDPP permits ingrowths of fibrous tissue
inside and around, it is a nonabsorbable material that stabilizes the upper lateral cartilages in their new position and maintains
the appropriate internal valve angle. The authors used this material for 15 patients undergoing secondary (n = 12) and tertiary (n = 3) rhinoplasty because of valvular collapse. During the mean follow-up period of 16 months (range, 8–30 months), neither
complication nor recurrence of airway obstruction occurred.

A double-blind, randomized trial with placebo control was planned to evaluate the effects of corticosteroids (betamethasone,
dexamethasone, methylprednisolone) in approximately equivalent doses (8 mg dexamethasone/day), and to compare their effects
with that of tenoxicam, an antiinflammatory drug, on both the edema and ecchymosis in open rhinoplasty with osteotomies. For
this study, 40 patients were divided randomly into five groups of 8 patients each, which received, respectively, betamethasone
(group 1), dexamethasone (group 2), methylprednisolone (group 3), tenoxicam (group 4), and placebo (group 5). Open rhinoplasty
with osteotomies was performed by the same surgeon with the patient under general anesthesia. Drugs were administered just
before the induction of anesthesia and continued for 3 days. Only acetaminophen was used to control postoperative analgesia.
Digital photographs of each patient were taken on postoperative days 1, 3, and 7. Scoring was performed separately for eyelid
swelling and ecchymosis by three observers independently using a graded scale from 0 to 4. No statistically significant differences
existed among the five groups in terms of age, sex, duration of surgery, amount of bleeding, and intravenous fluid administration
during the surgery. On postoperative days 1, 3, and 7, no differences in the levels of ecchymosis or edema among the steroid
groups, the tenoxicam group, and the control groups were observed. In conclusion, the authors observed no significant differences
among the different kinds of steroids administered in equivalent doses (8 mg dexamethasone/day). Steroids used in these doses
were not effective in preventing or reducing edema and ecchymosis after open rhinoplasty with osteotomies. Tenoxicam also
was not effective. No complications caused by the use of steroids were observed during the 6-month follow-up period. 相似文献

The correlations between the commonly used radiographic parameters, center-edge angle (CEA), acetabular-head index (AHI), acetabular index angle (AIA), acetabular angle (AA) and ACM angle, in normal, subluxated and dislocated hips were investigated in the radiographs of 364 normal, 23 subluxated and 19 dislocated hips of patients between 5 and 18 years of age. A significant correlation was observed between all the parameters in normal hips. A significant correlation between AIA and the other four parameters, and between CEA-AHI and AA-ACM, was noted in subluxated hips. AIA-AA and AIA-ACM had significant correlations in dislocated hips. It was concluded that measurement of more than one radiographic parameter might be better to exactly evaluate the radiographic hip anatomy in developmental dysplasia of the hip. 相似文献

It is controversial to perform bone surgery at the time of open reduction in developmental dislocation of the hip in children 12-18 months old. The purpose of this study is to investigate whether concomitant bone surgery is necessary in patients treated with medial open reduction in this age range. Patients that were under 12 months of age at the time of open reduction were compared with patients that were 12-18 months old. Forty-four hips of 30 patients treated with open reduction through Ferguson's medial approach have been included in the study. Mean follow-up was 19.6 years (13-27.5). Age at the time of open reduction was less than 12 months in 21 hips (group A) and 12 months or more in 23 hips (group B). There was no significant difference between two groups concerning avascular necrosis or unsatisfactory radiological outcome (Severin's groups III and IV). A higher rate of secondary bone surgery was necessary in group B than in group A. Although secondary bone surgery is needed at a higher frequency in children 12-18 months old, the radiological outcome is not significantly different for patients younger than 12 months. Therefore, the recommendation of concomitant bone surgery on a routine basis during open reduction in developmental dislocation of the hip in children 12-18 months old is debatable. 相似文献

BACKGROUND: There have been few anatomic studies on the foramina and roots of the lumbar region, and those available in human specimens are usually based on computed tomography and magnetic resonance imaging methods. METHODS: Using the recent breakthroughs in microscopic anatomic dissections, the roots and vertebral foramina of the lumbar region were examined in 15 cadavers. Morphometric analysis of the roots and vertebral foramina of 80 lumbar vertebral objects was conducted. RESULTS: The transverse and sagittal diameters of the lumbar intervertebral foramina were measured at each vertebral level. The median diameter of the lumbar neural foramina was 8.8 +/- 1.7 mm for the transverse and 19.4 +/- 2.7 mm for the sagittal planes. The widest median diameter of roots was 3.9 mm in the L4 root, and the narrowest was 3.3 mm in the L1 root. CONCLUSION: Quantitative measurements of the diameters of the neural foramina and roots of the lumbar region in anatomic dissection models may provide a deeper understanding about the pathologies of this region and influence the success of surgical interventions. 相似文献

BACKGROUND: cSDH is a rare form of bleeding in patients with ITP. Intracerebral hematoma or subarachnoid hemorrhage is more frequently reported in these patients. Spontaneous resolution of cSDH in patients with idiopathic subdural hematoma is uncommon. CASE DESCRIPTION: We report a case of spontaneous cSDH in a patient with ITP, and we review the related cases in the literature. In our patient, the hematoma resolved spontaneously despite very low platelet levels. There also was an incidental left parietal convexity meningioma. A review of the literature is presented, and the management of the patients is discussed. CONCLUSION: In patients with ITP, cSDHs may resolve spontaneously or with medical treatment, and surgery might be deferred except in emergency conditions or in patients with normal neurological findings. Close neurological and radiological observation along with the medical treatment may be appropriate in the management of patients with normal neurological findings. 相似文献

The split-thickness skin graft (STSG) donor sites have been treated with various and plenty of dressing techniques and materials. An ideal STSG donor site dressing should have antibacterial, hemostatic, and promoting epidermal healing properties. We have performed a prospective study to evaluate the effect of the oxidized regenerated cellulose on STSG donor site healing. Between January 2002 and January 2005, 40 patients who were operated in any kind of reconstructive operations with STSG donor sites were included in the study. One half of the wound was covered with oxidized regenerated cellulose and the other half of the same wound of the same patient was covered with fine mesh gauze treated with Furacin (nitrofurazone). The patients were grouped into 2 depending on the dressing technique: group I, semiclosed and group II, closed. The wounds were evaluated for healing time, infection, pain perception of the patient, and final esthetic results. The oxidized regenerated cellulose side of the group I was healed in a mean of 6.5 +/- 0.51 days; in group II, 5.4 +/- 0.50 days (range, 5-6 days). The fine mesh gauze treated with Furacin in group I was healed in a mean of 9.9 +/- 0.97 days (range, 8-11 days); in group II, 8.4 +/- 0.99 days (range, 7-10 days). There was a statistical significance between the oxidized regenerated cellulose side and the fine mesh gauze side (P < 0.001) in group I and group II separately. The difference between group I and group II was statistically significant in the oxidized regenerated cellulose side (P < 0.001), and the difference between group I and group II was statistically significant in the fine mesh gauze side (P < 0.005). The antibacterial, hemostatic, and absorbable property of the oxidized regenerated cellulose could ensure the utilization as an alternative STSG donor site dressing, especially because the positive influence over the wound healing was proven. 相似文献
