眼眶

Circular orbit is a long, small eyes like a black sesame seeds, from time to time in telescopic eyes.

眼眶是长圆形的，小小的眼睛就象一粒黑芝麻，不时地在眼眶里伸缩。

The ethmoid part because of the osteoma, is due to orbital osteoma oppression near the nerve, before the swelling and pain caused orbit.

而因筛窦部位的骨瘤，则是因骨瘤压迫到眼眶附近的神经，才引起眼眶的肿痛。

In 1988 a lacrimal gland tumor was incompletely removed from the left orbit of a 36-year-old woman and diagnosed as "solid basaloid adenoid cystic carcinoma". Soon after, an exenteration of the orbit was performed. In 1998, upon review of the initial histopathology, the diagnosis of solid adenoid cystic carcinoma was changed to basal cell adenocarcinoma..

方法；1988年一个36岁的妇女的泪腺肿瘤从左眼眶不完全摘除，诊断为"实质性基底细胞囊腺癌"，不久进行了眼眶内容去除术。1998年对原始的组织病理学进行回顾，实质性基底细胞囊腺癌被更正为基底细胞腺癌。

It can be show different characteristics in the MRI of the orbital diseases, the sheath of the orbital tumor contain certain characteristics, can express soft muscle locate the orbital compartment or outside. and the tumor showed hypointensity or hypo-or isointense mass on T1-weighted images, and iso-or hyperintense or hyperintense mass on T2-weiglited images, inflammation expresses for the orbital inside limit the soft muscle or widespreads excrescent signal, and showed hypo-or isointense mass on Ti-weighted images, and iso-or hyperintense mass on T2-weighted images, the companion contain fatty the eye muscle big or the eye wreath increase thick, the lachrymal gland is swollen.

其在MRI表现各具有影像学特征，眼眶肿瘤多表现为位于眼眶内、外的局限性软组织肿块，MR T1WI呈等或稍低信号，T2WI呈高或等信号多见；炎性假瘤则表现为眶内局限性软组织肿块或弥漫性异常信号，MR T1WI呈低信号，T2WI呈高信号，常伴有眼肌肥大或眼环增厚，泪腺肿大等。

AIM:To study the treatment plans of different type orbital fractures and to investigate the best method of every type.

目的：研究不同类型的眼眶区骨折的治疗方案，探讨不同类型眼眶骨折的最佳治疗方法。

摘要目的：研究不同类型的眼眶区骨折的治疗方案，探讨不同类型眼眶骨折的最佳治疗方法。

Results Among the 62 cases, 23 were simple orbital wall fracture and the other 39 were complex orbital fracture.

结果 62例眼眶骨折中23例为单纯眶壁骨折，其中18例术前有复视，19例出现Ⅰ级或Ⅱ级眼球运动障碍；术后12个月时，仅5例残留Ⅰ级或Ⅱ级复视，5例有Ⅰ级眼球运动障碍。39例复合性眼眶骨折中，其中36例术前有复视，38例发生眼球运动障碍；术后12个月时，29例有复视（6例为Ⅲ级复视），22例有眼球运动障碍。

Correlation of submaxillas curve has been test, and experiments show that curves of submaxilla from the same person are correlated, while the curves of submaxilla from different persons are uncorrelated. 4. The feature of skull contour has been extracted by using polar -radius-invariant-moment, Fourier descriptors and wavelet descriptors separately.

4：将极半径不变矩、傅立叶描述子、小波描述子作为提取颅骨轮廓和眼眶轮廓信息的主要手段，并且构造了应用于眼眶边界的相对量作为特征量。

Objective In order to provide early valuable information in diagnosis, prediction and treatment, the ratio between the expansion of orbital volume behind the axis of the globe and the degree of the enophthalmos was studied,and the time and degree of enophthalmos were observed.

目的：通过测量眼眶爆裂性骨折伴有眼眶扩大患者的后部眼眶容积、观察眼球内陷出现的时间及程度，研究后部眶容积扩大与眼球内陷的关系比值，为病情预测和眶内填充手术提供比较精确的参考数据。

Through a comparative study of ~(99)Tc~m-DTPA and ~(99)Tc~m-OCT SPECT orbital imaging,evaluated the clinic significance of two imaging in estimating activity of TAO.The aim of this study was to develop a new method:simple,rapid and costefficient method for staging patients with TAO.

本研究采用~(99)Tc~m-二亚乙基三胺五乙酸~(99Tc~m-diethylene tri-aminepentaacetic acid，~(99)Tc~m-DTPA进行眼眶显像并与~(99)Tc~m-奥曲肽~(99Tc~m-octreotide，~(99)Tc~m-OCT眼眶显像进行比较，研究其在反映TAO患者眶周炎性程度的价值，旨在探索一种新眼眶显像方法：既经济又迅速，显像效果稳定又可靠。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
