您要查找的是不是：
- posterior ethmoidal sinuses 后筛窦(解)Sinus ethmoidales posteriores{拉}
- When disease involves the sphenoid, the sinus can be penetrated either intranasally or through the posterior ethmoid. 当病变累及蝶窦，可以经鼻内和后组筛窦进入蝶窦。
- Results:The ostiums apertures of maxillary sinus were flowing freely,neither conglutination between middle turbinate and outersides of nasal cavity nor atresia of ethmoid sinuses occurred. 结果:患者均未见上颌窦自然口黏连闭锁,中鼻甲与鼻腔外侧壁黏连及筛窦腔闭塞。
- There is diffuse mucosal thickening of bilateral maxillary sinuses, ethmoidal sinuses and sphenoidal sinuses. 在两侧的上颌窦、筛窦以及蝶窦的粘膜可见弥散性增厚。
- Diffuse mucosal thickening affecting bilateral maxillary sinuses, ethmoidal sinuses and sphenoidal sinuses , suggesting pansinusitis change . 上颌窦、筛窦以及蝶窦的粘膜弥散性增厚提示可能是全鼻窦炎。
- The detection frequency of anterior, middle and posterior ethmoidal canal (AEC, MEC, PEC) was 100%, 42.9%, 99.5%. 筛前、筛中、筛后动脉管的显示率分别为100%25、42.;9%25、99
- These approaches also provide ac cess to the sphenoid and ethmoid sinuses and the sella, and the medial part of the floor of the anterior fossa. 同时，这些入路也可到达蝶窦、筛窦、蝶鞍以及前颅窝底内侧部。
- The posterior ethmoid cells are easily identified as they are larger, wider, and fewer in number than anteriorly. 后组筛窦的气房一般大而宽,在数量上也少于前组筛窦,容易确定。
- Methods Ethmoid sinuses of 250 cases were scanned transversally by MSCT with coronal and sagittal views were reconstructed. 目的评价多排螺旋CT三维重建技术在显示筛窦解剖方面的作用,同时探讨筛窦解剖变异及其临床意义。
- Objective:We observed 3-5 years follow-uip results of the patients with mucoceles of sphenoid frontal and ethmoid sinuses on the marsupialization using nasal endoscope. 目的：应用鼻内窥镜对蝶、额、筛窦粘液囊肿的病人施行袋状化手术，分别随访3-5年，观察治疗结果。
- Methods Various benign neoplasms from ethmoid sinuses were removed under nasal endoscope,these were 7 cysts,3 cases of osteofibroma,1 adenoma and 2 cases of osteoma. 方法经鼻内镜治疗筛窦囊肿7例,骨化纤维瘤3例,腺瘤1例,骨瘤2例。
- Forobtaining the bets result,the height of maxillary-ethmoid and the height from the up-edgeof maxillary-ethmoid plate to the roof of posterior ethmoid were measured. 鼻前棘至后筛顶后缘的距离及角度，观察中鼻甲的走行及附着，筛骨水平板的形态及后筛窦的分度及变异，为临床手术提供了一定的解剖学依据。
- Generally, two-thirds of mucoceles or mucopyoceles occur in the frontal sinuses, one-third in the ethmoidal sinuses, and extremely rare in the maxillary or sphenoidal sinuses and concha bullosa. 摘要黏液囊肿或黏液脓性囊肿约三分之二发生于额窦，三分之一发生于前筛窦，而发生于蝶窦、后筛窦及上额窦者并不常见，至发生于中鼻甲泡者则更少。
- The results were analyzed by the statistical software SPSS. Results:The detection frequencies of anterior, middle and posterior ethmoidal foramen (AEF,MEF,PEF) were 100%,42.9% and 99.5%. 结果眶内壁筛孔总数显示为单孔、二孔、三孔、四孔、五孔的比例分别为0.;5%25、54
- Keywords Endoscopy Posterior ethmoid sinus Postocular tissue proper Operative; 内窥镜;后组筛窦;眼球后;手术;
- The posterior limit of the posterior ethmoid is the skull base.At this point, it is more solid than it is anteriorly and serves as a reliable and safe location for its identification. 后组筛窦的后界是颅骨，在此处，比前方坚实的骨质，可以做为确定后界可靠和安全的标帜。
- Dissection is then carried posteriorally along the inferior border of the ethmoid to the lamina basalis.Through the lamina basalis lies the posterior ethmoid. 接著向后沿筛窦的下缘切除筛窦至基板，通过基板即进入后组筛窦。
- Purpose: To report a case of exophthalmos related to frontal and ethmoid sinusitis with subperiosteal abscess. 摘要目的：报告一个因额窦与筛窦鼻窦炎及骨膜下脓疡而引起的突眼症病例。
- Ethmoid sinusitis is frequently complicated in children by orbital cellulitis and abscess. 筛窦炎在儿童中常并发眼眶蜂窝织炎及脓肿。
- According to the X-ray report, I can say that you are having maxillary sinusitis and ethmoid sinusitis. 根据X线片报告，我可以诊断你患了上颚窦炎和筛窦炎。
