Results (1)The agger cells existed in 99% of the cases, the development of the agger cells in 9～16 years old children, and adult had no difference;(2) The morphology of agger cells differed widely, but its relationship to the anterior border of the middle nasal concha, bulla ethmoidalis and nasolacrimal canal was quite stable;(3) The upward pneumatization of the agger cells was not related to deviation of nasal septum, but closely related to the development of the frontal sinus;(4) The anterior nasosinusitis often influenced the agger cells and might result in hyperosteogeny.

结果 ①绝大多数病例（99%）有鼻丘气房，儿童（9～16岁）鼻丘发育与成人相比无差异性；②鼻丘形态变化很大，但与中鼻甲前端、筛泡和鼻泪管的关系是恒定的；③鼻丘向上气化程度与额窦发育关系密切，鼻中隔偏曲对其发育无明显影响；④前组鼻窦的广泛炎症易波及鼻丘，并可出现鼻丘骨质增厚。

Objective To study the scanning technique of HRCT for demonstrating the anatomical structures of the frontal sinus and its drainage channels, including ostium of frontal sinus, nasofrontal duct, ethmoid infundibulum, middle nasal meatus, etc.

目的 探讨高分辨力CT扫描对额窦引流通道(鼻额管、额窦窦口、筛漏斗、中鼻道等)解剖结构的显示及其扫描技术。

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%。

Results The total 100 frontal sinuses were all revealed. Of 100 ostia, nasofrontal ducts, ethmoid infundibula, and middle nasal meatuses, 4 didn't show up and 96 could be viewed with air channel and bone channel structures well demonstrated in 70, and the remaining 26 still showed their bone channel structures though their air channel structures were vanished.Conclusion The structures of the ostium of frontal sinus, nasofrontal duct, ethmoid infundibulum, middle nasal meatus, etc.

结果 50例被检查者的50个额窦全部显示；100个窦口、鼻额管、筛漏斗及中鼻道结构，4个未显示，96个被显示，其中70个窦口、鼻额管、筛漏斗及中鼻道的气道结构和骨结构均清晰可见，26个窦口、鼻额管、筛漏斗及中鼻道的气道结构消失但骨结构仍可见。

Muzzle: Of medium length; that is, the distance from the tip of the nose to the stop is equal to the distance from the stop to the occiput.

鼻口部：中等长度；意思是，从鼻子的顶端到额段的距离等于从额段到后头部的距离。

Methods 30 cases of nasal soft tissue de fects were reconstructed by different kinds of local flaps according to modified Burget′s nasal subunit. The Rintala flaps were used above the lowest level of low eyelids; at the area between low eyelids and the alar groove, the dorsal def ects were covered by ax-like local flaps and defects on side wall were reconstru cted by flaps rotated from the contralateral wall covered by skin graft; when it was below the highest level of alar groove, nasolabial flaps with subdermal ped ical were applied to nasal tip defection, and nasolabial local flaps to alar def ects, axial nasodorsum flaps supplied by the lateral nasal artery to defects inv olving columellae.

结合Burget鼻部美学分区，将其再分为三个区域，根据分区选用局部或邻位皮瓣修复鼻部各区软组织缺损30例(鼻根部以Rintala鼻额部局部皮瓣推进3例；鼻中段的鼻背部行双侧斧状局部皮瓣旋转3例；鼻侧壁行对侧壁局部皮瓣转移，供区植皮4例；鼻端部以鼻唇沟皮下蒂岛状瓣转移修复鼻尖部7例；鼻唇沟局部皮瓣旋转修复鼻翼部7例；鼻背轴型皮瓣旋转修复鼻小柱6例)。

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.
