OBJECTIVE To discuss the method, efficacy and safety of endoscopic frontal sinus surgery in the route anterior to ethmoidal bulla.

目的 探讨经鼻内镜筛泡前径路额窦开放术的技术路线，讨论该术式在额窦开放中的疗效和安全性。

Surgical procedure anterior to ethmoidal bulla is a safe and effective surgical model for frontal sinus lesions and is therefore worthy of broad recommendation.

经鼻内镜筛泡前径路额窦开放手术是一种解剖标志易辨认、技术路线安全、疗效肯定的术式。

METHODS Twenty three adult patients (36 sides) with chronic frontal sinusitis received endoscopic frontal sinus surgery in the route anterior to ethmoidal bulla.

选取23例（36侧）确诊为慢性额窦炎的成人病例。采用经鼻内镜筛泡前径路术式开放额窦。

Objective To study the x-ray and CT findings of mucoceles of frontal and ethmoid sinuses and their value of diagnosis.

目的是研究额、筛窦粘液囊肿X线和CT表现，并探讨其在诊断鼻窦粘液囊肿方面的价值。

Purpose: To report a case of exophthalmos related to frontal and ethmoid sinusitis with subperiosteal abscess.

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。

The results in this paper are possesses an important meaning to the position of the ostium of frontal sinus, adjacency relation and prevent anterior ethmoid artery from the risk of injury.

四、结论本文的结果对鼻内镜下额窦手术的额窦口定位、与毗邻的关系以及预防筛前动脉的损伤有其重要的指导意义。

And cribriform roof is behind it. On endoscope, we can see anterior ethmoid artery is in the insertio of basal lamella of bulla and frontal sinus, in about 2mm range. They are all behind along ostium of frontal sinus and in front of the basal lamella of bulla, from posterolateral skull base to anteromedial skull base.

鼻内镜下，筛前动脉位于筛泡基板与颅底附着处、前后2 mm范围内，沿颅底由后外向前内走行，其行程始终位于额窦开口后缘的后方和筛泡基板的前方。

The main indexes included the condition of frontal antrum, ethmoid sinuses, sphenoid sinus and maxillae antrum that was involved in, the types of the inflammation （mucous thickening, inflammatory fluidify and submucosal cyst） and its MRI appearance.

主要观察指标包括额窦、筛窦、蝶窦、上颌窦受累情况，各窦病变类型（黏膜增厚、炎性积液、黏膜下囊肿）及相应的MRI表现。

There was significant difference in frequency of cells in frontal drainage system between sinusitis group and control group, including terminal cell, anterior ethmoid cell, agger nasi cells, and perifrontal cells.

两组间额窦引流通道内出现并影响额窦通气引流功能的部分气房（终末气房、前筛气房、鼻丘气房和额气房）出现率的差异有显著性。

With the foundation of HRCT, drainage passage and ostium of the frontal sinus were identified and opened through the landmark of agger nasi cells, the superior attachment of the uncinate process and the anterosupterior basal lamella of the bulla.

经CT明确诊断的额窦病变33例(56侧)，以CT扫描成像为基础在鼻内镜下以鼻丘气房、钩突附着上缘及筛泡前上缘为标记开放额隐窝及额窦。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
