眶下管的应用解剖及其临床意义

The applied anatomy and clinical significance of infraorbital canal

目的:探讨眶下管的形态结构,为临床应用提供有关解剖学资料。方法:取成人头颅骨72例(144侧),对眶下管的位置、口径大小、毗邻关系进行观察和测量,并比较左右眶下管有无显著性差异。结果:眶下管长度左侧为(13.97±2.15)mm、右侧为(13.63±1.75)mm;与冠状面的夹角左侧为(42.15±8.46)度、右侧为(45.77±6.08)度;上壁厚左侧为(0.39±0.29)mm、右侧为(0.26±0.14)mm;下壁厚左侧为(0.61±0.20)mm、右侧为(0.55±0.26)mm;左右均无显著性差异(P>0.05)。结论:眶下管解剖结构复杂,在临床诊疗中应加以注意。

Objective： To explore the shape and structure of infraorbital canal for providing anatomy data for clinical application. Methods： Take 72 cases （144 sides） of adult skull, observe and measure the position, bore and adjoin relation of infraorbital canal, compare with left and right infraorbital canal. Results： The length of left infraorbital canal was （13.97 ± 2.15） mm, right was （13.63 ± 1.75） mm ; the left side between infraorbit al canal and coronal angle was（42.15±8.46）°, right was（45.77±6.08）° the left side of thickness of upper wall was（0. 39±0. 29）mm, right was （0. 26±0. 14）mm;the left side of thickness of lower wall was（0. 61±0. 20）mm, right was（0. 55±0. 26）mm. There was no strinking difference between the left and right infraorbital canal（P〉0. 05）. Conclusion ：The structure of infraorbital canal is complicated, so more attention should be paid to the clinical appliation.
