| 目的 采用容积CT观察颧颞管的解剖特点.方法 对50例(100侧)成人眼眶容积CT图像进行标准化处理,观察颧颞管的显示率、形态、分支、平均长度、内孔起源位置、外孔(颧颞孔)至眶内缘距离、内外孔数量及孔径.结果 颧颞管显示率为96.00%(96/100),为管状或纡曲形,共有46侧颧颞管发出返回眶内的分支.颧颞管根据走行分4型,分别为单支型(39支)、两支型(8支)、分叉型(36支)、单支+分叉型(13支).内孔位于眶下裂(55/115,47.83%)或眶外侧壁(60/115,52.17%),外孔开口于颞窝(100/119,84.03%)或颧骨面(19/119,15.97%).颧颞管长度为(12.4±4.9)mm.外孔距眶边缘(6.5±2.7)mm.颧颞管内孔、外孔可分为1孔或2孔型.内孔直径为1.0mm(0.8~1.2 mm),外孔为0.8mm(0.7~1.0mm),男性内、外孔的孔径均大于女性.结论 颧颞管是眼眶外壁内常见的神经血管通道,其走行及开口变异多样. |

| Objective To observe the anatomy of zygomaticotemporal tube with volume CT. Methods Volume CT images of orbits in 50 adults (100 sides) were observed after standardization. The presence, morphology, branches, mean length, origin, distance from opening foramen (zygomaticotemporal foramen, ZTF) to the inner margin of lateral orbit wall, number and diameter of the openings were evaluated. Results The presence of zygomaticotemporal tube was 96.00% (96/100), which might be straight or tortuous. A branch course back to the orbit was present in 46 of 100 sides. The zygomaticotemporal tube could be classified into 4 types based on the morphology, i.e. single tube (n=39), double tube (n=8), bifurcation (n=36) and single tube combined with bifurcation (n=13), originated from inferior orbital fissure (55/115, 47.83%) or the lateral orbit wall (60/115, 52.17%), opened in the temporal fossa (100/119, 84.03%) or the surface of zygomatic bone (19/119, 15.97%). The mean length of zygomaticotemporal tube was (12.4±4.9) mm. ZTF was (6.5±2.7)mm away from the inner margin of the lateral orbit wall. One or two foramina of the origin foramen and ZTF were seen. The diameter of origin foramen and ZTF was 1.0 mm (0.8-1.2 mm) and 0.8 mm (0.7-1.0 mm), respectively, and both were larger in males. Conclusion The zygomaticotemporal tube is commonly present in the lateral orbital wall with a variety of morphology, origin and openings. |
