目的经Poppen入路在行小脑幕切开前后对松果体区的显露及其损伤程度进行定量综合评价。方法通过对成年人带颈头颅标本5具(10侧),模拟常规的Poppen入路的手术操作,在行小脑幕切开前后,按Ammirat标准对松果体区的显露程度进行评价,用Horgan法计算出显露面积,并根据损伤程度评分评价其损伤程度。结果经Poppen入路在行小脑幕切开前后对松果体区的显露程度评分分别为1分和3分;显露面积分别为(566.20±80.72)mm2、(1100.31±123.46)mm2,两者相较,差异显著(P0.01);经Poppen入路行小脑幕切开前损伤程度积分为4分,小脑幕切开后损伤程度积分为6分。结论经Poppen入路对松果体区肿瘤手术显露范围广泛,损伤程度小,且可以根据肿瘤的大小和发展方向进行扩大显露,有利于最大程度的保护大脑深部静脉和中脑四叠体,同时全切肿瘤。  相似文献

ObjectiveWe sought to examine the current skin quality trends and gaps in clinical practice in the Asia Pacific region and develop a practical guide to improve skin quality.MethodsMedical practitioners from 11 countries in the Asia Pacific region completed an online survey on current trends in skin quality treatment. A panel of 12 leading experts convened for a virtual meeting to develop a practical guide for skin quality improvement.ResultsA total of 153 practitioners completed the survey. The four most common skin quality issues were uneven skin tone, skin surface unevenness, skin laxity, and sebaceous gland hyperactivity and enlarged pores. Most practitioners reported using a combination of treatment modalities for each skin quality issue. It was also observed that each treatment modality could be used to treat several skin quality issues. A multimodal approach targeting different interrelated issues across the tissue planes was recommended for balanced results. The panel developed a practical guide for the appropriate combinations and sequence of treatments, and created treatment protocols for specific skin quality outcome goals. The guide employed an “inside-out” approach, treating the deeper tissue planes prior to the superficial layers to achieve harmonious results.LimitationsFuture studies are needed to support the recommended treatment protocols for skin quality improvement.ConclusionThese findings provide valuable insights on current skin quality trends and gaps in clinical practice. The practical guide provides a framework for practitioners to customize their treatment plan according to each patient’s needs.  相似文献

ObjectiveThis study aims to describe and analyze the transoral and transnasal approaches for pathologies of the ventral atlas and axis vertebrae, which are considered technically challenging regions for diagnostic biopsy.MethodsA series of transnasal endoscopic approach (TNA) and transoral approach (TOA) biopsies for the pathologies of the first and second cervical vertebrae were conducted and retrospectively analyzed from July 2014 to May 2021. The depth of the biopsy trajectory was measured on computed tomography images for all nine patients (eight males and one female with an average age of 58.11 ± 11.60 years), as were the coronal, sagittal, and vertical biopsy safe ranges. The characteristics of each lesion, including radiographic features, blood supply, and destruction of anterior or posterior vertebral body edges, were evaluated to guide the biopsy. Four biopsy core techniques (BCTs), including “lesion perforating”, “aspiration”, “cutting‐and‐scraping” and “biopsy forceps utilization” were elaborated in this study. The biopsy procedures and periprocedural precautions were demonstrated. Patient demographics, clinical data, lesion characteristics, diagnostic yield, and complications were recorded for each case.ResultsEight TOA biopsies for the axis vertebral body and one TNA biopsy for the atlas anterior arch were successfully performed and yielded adequate pathologies. All biopsies were organized based on the preprocedural radiographic measurements, which showed that the average length of biopsy trajectory and coronal, sagittal, and vertical safe biopsy ranges were 85.00 ± 5.88, 20.63 ± 4.75, 16.25 ± 1.49, and 24.63 ± 2.26 mm, respectively, and these corresponding data were 95, 36, 9, and 26 mm in the TNA patient. Six osteolytic lesions (66.7%), one osteoblastic lesion (11.1%), and two mixed lesions (22.2%) were observed, among which seven lesions had a rich blood supply. Biopsy forceps and core needles were utilized to obtain samples in six and three patients, respectively. All the TNA and TOA biopsies were performed with cooperative application of multiple BCTs under compound anatomic and stereotactic navigations. Intraprocedural or postprocedural complications occurred in no patients who underwent the biopsy in the follow‐up period (1–39 months). No significant differences were found between the preprocedural and postprocedural blood indexes and visual analogue scale scores.ConclusionWith a sophisticated preprocedural arrangement, cooperative application of BCTs, and careful periprocedural precautions, transnasal endoscopic and transoral biopsies are two feasible, efficient, and well‐tolerated procedures that achieve satisfactory diagnostic yield, complication rate, and clinical outcome.  相似文献

目的探讨咽旁间隙神经鞘瘤的诊断与手术入路方式的选择。方法对咽旁间隙神经鞘瘤患者14例病历资料进行回顾性分析,术前根据CT和MRI判断肿瘤与扁桃体包膜距离关系及肿瘤主体位置考虑手术径路,与扁桃体包膜距离≤1cm、肿瘤主体突入到口内者行经口内径路,与扁桃体包膜距离1cm、瘤体主体突向外侧者经颈外径路,手术径路与肿瘤大小关系不大。经口内径路4例,颈外径路10例。结果所有患者均获得顺利手术,术后随访6个月~6年均未见复发。结论颈部CT、MRI及DSA是诊断及鉴别诊断的良好手段,手术径路取决于肿瘤与扁桃体包膜的距离及肿瘤主体位置,无论采取何种径路,均无严重的并发症。  相似文献

ObjectiveThis paper establishes levels and patterns of ability and willingness to pay (AWTP) for contraceptives, and associated factors.Study designA three-stage cluster and stratified sampling was applied in selection of enumeration areas, households and individuals in a baseline survey for a 5-year Family planning programme. Multivariable linear and modified Poisson regressions are used to establish factors associated with AWTP.ResultsAbility to pay was higher among men (84%) than women (52%). A high proportion of women (96%) and men (82%) were able to pay at least Ug Shs 1000 ($0.27) for FP services while 93% of women and 83% of men who had never used FP services will in future be able to pay for FP services costed at least Shs 2000 ($0.55). The factors independently associated with AWTP were lower age group (<25 years), residence in urban areas, attainment of higher education level, and higher wealth quintiles.ConclusionAWTP for FP services varied by different measures. Setting the cost of FP services at Shs 1000 ($0.27) will attract almost all women (96%) and most of men (82%). Key determinants of low AWTP include residence in poor regions, being from rural areas and lack of/low education.Implications statement: Private providers should institute price discrimination for FP services by region, gender and socioeconomic levels. More economic empowerment for disadvantaged populations is needed if the country is to realise higher contraceptive uptake. More support for total market approach for FP services needed.  相似文献
