The ostium of frontal sinus Positions should be divided into two type by the interaction of basal lamella of bulla and cribriform roof. TypeⅠ: The ostium of frontal sinus is located in lateral sinus, flows through superiorsemilunar hiatus to middle nasal meatus. It is about 20%. TypeⅡ: The ostium of frontal sinus is located in ethmoid infundibulum, frontal recess and its cell, flows through interior semilunar hiatus to middle nasal meatus. It is about 80%. Among them there are about 62.5% in ethmoid infundibulum, about 37.5% in frontal recess.

额窦鼻口的位置可根据筛泡基板与筛顶连接的情况划分为两种类型：Ⅰ型额窦的鼻口开口于侧窦，经上半月裂流入中鼻道，约占20%；Ⅱ型开口于筛漏斗、额隐窝及其气房，经下半月裂流入中鼻道，约占80%，其中开口于筛漏斗约为62.5%；开口位于额隐窝约为37.5%。

Biatrial and right ventricular triple chamber pacinmg is founded through implanting coronary sinus lead to pace left atrium on the base of conventional right atrial and right ventricular dual chamber pacing,which realizes the synchrony of electrical activities in both two atriums,remove interatrial conduction block and interatrial reentry,and prevent and treat atrial tachyarrhythmias induced by interatrial conduction block.

在常规右房、右室双腔起搏的基础上，植入冠状窦电极起搏左房，建立双房右室三心腔起搏系统，实现双房电活动的同步化，消除房间传导阻滞和房间折返，防治由房间传导阻滞引起的房性快速性心律失常。

Grind down the frontal sinus from superciliary archand show nasal ostium of frontal sinus, basal lamella of bulla and its front, cribriform roof.

重点观察筛漏斗、额隐窝及其气房、额窦窦口及鼻腔开口、筛泡基板与筛顶的连接情况。

Methods Axial lamellate computed tomography scans of frontal drainage system were firstly performed with four layers spiral CT, and coronal, sagittal sections then reconstructed with AW 4.1 software on 65 adults ,both frontal sinusitis group (35 cases, 66 sides) and control group (30 cases. 59 sides). Related cells in frontal drainage system were studied and compared dynamically.

采用4层螺旋CT对65例成人，30例正常成人及35例额窦炎患者的额窦引流通道行水平位薄层扫描后用Advantage Windows 4.1(AW4.1)影像工作站进行冠状位、矢状位重建，动态分析和比较两组额窦引流通道内出现的相关气房。

The causes were right auricle injury by violently placing a electric catheter to it (n=2),coronary sinusinjury by violently placing a electric catheter to distal CS (n=3) and by intracardiac electric defibrillation using electric catheter electrodes of high right atrium and CS as current loop(n=1),perforations of right atrial wall (n=3) and left atrial wall(n=2) by sliding up of the transseptal set,and perforation of left auricle by misplacing the mapping catheter of left superior pulmonary vein to it (n=1). 10 cases of acute tamponade occurred during operation, and 2 after operation.12 patients were treated successfully with urgent pericardiocentesis, and no patients required emergency surgery.

引起心包填塞的原因有：①放置电极导管至右心耳时用力过大致右心耳损伤(2例)；②放置电极导管至冠状静脉窦时，因导管不易进入远端而用力过大致CS损伤(3例)；③心内电除颤时采用高位右房和CS电极作回路，致CS损伤(1例)；④房间隔穿刺系统向上滑动穿破右房(3例)和左房(2例)；⑤放置左上肺静脉标测电极时导管误入左心耳致其穿孔(1例)。10例急性心包填塞出现于术中，另2例术后发生。12例患者经紧急心包穿刺引流均成功治愈，无1例需外科急诊手术。

ABSTRACT］ Objective: To provide anatomical evidence for frontal sinus surgery through the agger nasi cell approach and the uncinate process approach by using the lamellar sectional anatomy image. Methods: The computerized cryomilling technique was used to obtain the continuous sectional data of the nasal parts.

目的：应用鼻腔额窦的薄层断面解剖图像，追踪额窦引流通路，测量鼻丘气房、钩突及其他的相关数据，为额窦的鼻丘径路及钩突径路手术提供解剖学依据。

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.
