OBJECTIVE

The purpose of this study was to determine the prevalence of frontoethmoidal cells in normal Chinese subjects.

METHODS

Two hundred and two Chinese subjects without symptoms of frontal sinus disease were undergone spiral computed tomography (CT). The multiplanar reconstruction images were evaluated using a standard triplanar reconstruction protocol on a computer workstation.

RESULTS

There were 121 males and 81 females. The mean age was (39.4 +/- 13.5) years. Of all the frontal cells identified in 159 sides (39.4%) of frontal recesses, the prevalence of type I, type II, type III and type cells were 24.3% (98 sides), 6.9% (28 sides), 8.2% (33 sides) and 0% (0 side) respectively. Suprabulbar cell, supraorbital ethmoid cells, and frontal bulbar cell were identified in 148 sides (36.6%) Jian-hu, 22 sides (5.4%), and 36 sides (8.9%) respectively. While the interfrontal septal cells was found in 25 patients (12.4%). The prevalence of agger nasi cell was 94. 1% (380 sides). Two hundred and forty-four uncinate processes (60.4%) had one superior attachment for each uncinate process; the other 160 uncinate processes (39.6%) had two superior attachments for each uncinate process. The single superior attachment of the uncinate process into the surrounding structures was identified to have the following distribution: 53.0% (n=214) to the lamina papyracea, 5.2% (n=21) to the middle turbinate, 2.2% (n=9) to the skull base. Most of the uncinate process' two superior attachments were either into the lamina papyracea and the skull base (27.5%, n=111) or into the lamina papyracea and the middle turbinate (8.7%, n=35). The other 14 uncinate processes (3.5%) superiorly attached to the skull base and the middle turbinate. The prevalence of recessus terminalis was 89.1% (n=360).

CONCLUSION

The result demonstrated the normal frontal recess pneumatization patterns in normal Chinese.

目的

本研究旨在确定正常中国人群中额筛窦气房的发生率。

方法

对202例无额窦疾病症状的中国受试者进行螺旋计算机断层扫描（CT）。在计算机工作站上使用标准的三平面重建协议对多平面重建图像进行评估。

结果

男性121例，女性81例。平均年龄为（39.4±13.5）岁。在159侧（39.4%）额隐窝中识别出的所有额气房中，I型、II型、III型和IV型气房的发生率分别为24.3%（98侧）、6.9%（28侧）、8.2%（33侧）和0%（0侧）。球上气房、眶上气房和额球气房分别在148侧（36.6%）、22侧（5.4%）和36侧（8.9%）中被识别出。而额间中隔气房在25例患者（12.4%）中被发现。鼻丘气房的发生率为94.1%（380侧）。244个钩突（60.4%）每个钩突有一个上附着点；另外160个钩突（39.6%）每个钩突有两个上附着点。钩突单一上附着于周围结构的分布情况如下：53.0%（n=214）附着于纸样板，5.2%（n=21）附着于中鼻甲，2.2%（n=9）附着于颅底。大多数钩突的两个上附着点要么附着于纸样板和颅底（27.5%，n=111），要么附着于纸样板和中鼻甲（8.7%，n=35）。另外14个钩突（3.5%）上附着于颅底和中鼻甲。终末隐窝的发生率为89.1%（n=360）。
