单侧声带切除胸骨舌骨肌替代声带的临床应用 总被引:1,自引:0,他引:1
目的 探讨早期声带癌(TisN0M0或TiaN0M0)声带切除胸骨舌骨肌替代声带临床应用的可行性、技术操作及疗效。方法 选择7例早期声带癌(TisN0M0或TiaN0M0)施行单侧声带切除胸骨舌骨肌替代声带手术,术后通过观察替代声带活动情况、上皮化时间、声带闭合及发音情况评估手术疗效。结果 7例病例中6例发音一年左右接近正常,1例由于术中替代声带缝合不紧而出现缝合处断裂,替代声带挛缩,术后发音仍嘶哑明显。结论 胸骨舌骨肌替代声带,只要手术方法恰当,胸骨舌骨肌就能发挥良好的声带功能,改善术后发音质量,从而提高患者术后生活质量,值得推广应用。 相似文献

Anterior knee pain: the use of computerized tomography to assess the results of tibial tubercle transfer 总被引:1,自引:0,他引:1
Anterior knee pain is a common clinical problem. Patient assessment is difficult. Recently, it has been suggested that the so-called ‘skyline’ views of the patellofemoral joint have no role to play in screening for maltracking and some would suggest that computerized tomography (CT) offers a more accurate method of investigation. The aim of this study was to evaluate the performance of CT in the assessment of three populations: patients suffering form anterior knee pain, patients treated for this condition by tibial tubercle transfer and a control group. The patellofemoral joint was assessed by measuring the trochlear angle, the congruence angle and the patella tilt from the CT images. In summary, the preoperative group had significantly different values of each parameter when compared with other groups but the group that had undergone surgical correction did not demonstrate a significant alteration toward the values of the control group. This study suggests that CT was not useful as either a diagnostic tool or as a indicator of successful surgical outcome. 相似文献

To audit the accuracy of magnetic resonance (MR) staging of nasopharyngeal carcinoma (NPC) in daily reporting, the MR images of 101 adult patients with newly diagnosed NPC reported between December 1996 and February 2002 were reviewed retrospectively. Based on the American Joint Committee on Cancer/International Union Against Cancer (AJCC/UICC) TNM staging criteria (1997), the tumour staging obtained from the MR reports and the MR films was compared by two experienced head and neck radiologists. The number of patients being upstaged, downstaged or unchanged was noted. In all stages, the NPC staging obtained from the MR reports revealed 18 (17.8%) understaged, eight (7.9%) overstaged and 75 (74.2%) the same stage when compared to the staging obtained from the MR films based on the AJCC/UICC criteria. The percentage of patients being understaged or overstaged, in decreasing order of frequency, were stages II, III, IV and I. Magnetic resonance of NPC should be reported by radiologists who are not only familiar with the pathology of this condition and its pattern of spread but who should also base their reports on the AICC/UICC staging criteria. The necessity to improve our MR staging accuracy is largely because it determines the type of therapy to be given and this has to be appropriate and adequate for a successful treatment. 相似文献

Objective To assess the feasibility, efficiency and selectivity of adenovirus- mediated ge ne transfer to local arterial wall by protein- coated metallic stent. Methods A replication- defective recombinant adenovirus carrying the Lac Z reporter gene for nuclear- specific β- galactosidase (Ad- βgal) was used in this study. Th e coating for metallic stent was made by immersing it in a gelatin solution cont aining crosslinker. The coated stents were mounted on a 4. 0 or3. 0mmpe rcutaneous transluminal coronary angioplasty (PTCA) balloon and submersed into a high- titer Ad- βgal viral stock (2×10(10)pfu/ml) for 3 min, and then im planted into the carotid arteries in 4 mini- swines and into the left anterior d escending branch of the coronary artery in 2 mini- swines via 8F large lumen gui ding catheters. The animals were sacrificed7 (n=4), 14 (n=1) and 21 (n=1) days after implantation, respectively. The β- galactosidase expression was as sessed by X- gal staining. Results The results showed that the expression of transgene was detected in all animal. In 1 of carotid artery with an intact intima, the β- gal expression was l imited to endothelial cells. In vessels with denuded endothelium, gene expressi on was found in the sub- intima, media and adventitia. The transfection efficie ncy of medial smooth muscle cells was 38. 6%. In 2 animals sacrificed 7 days af ter transfection, a microscopic examination of X- gal- stained samples did not s how evidence oftransfection in remote organs and arterial segments adjacent to the treated arterial site.Conclusions Adenovirus- mediated arterial gene transfer to endothelial, smooth muscle cells and adventitia by protein- coated metallic stent is feasible. The transfection efficiency is higher. The coated stent may act as a good carrier of adenovirus - mediated gene transfer and have a potential to prevent restenosis following PT CA. 相似文献

The purpose of this study is to compare health‐related quality of life (HRQoL) and emotional distress among diverse cancer survivors who had completed all treatment within the previous year. A convenience sample of 353 cancers survivors (lung, head and neck, breast and prostate cancers) were recruited to complete a survey, which consisted of (i) Hospital Anxiety and Depression Scales; (ii) Chinese version of the Functional Assessment of Cancer Therapy—General version; and (iii) demographic and clinical data. The HRQoL scores were similar among the four types of survivors. Mild anxiety and depression levels were reported, but no significant difference was noted. Younger females with financial burdens and uncertain prognosis were particularly associated with HRQoL and emotional distress. Further studies are essential to identify specific problems that cancer patients experience after cancer diagnosis that might lead to the early detection of those most at risk of ongoing problems. 相似文献
