摘要
目的 :研究眶内侧壁血管神经孔的变化情况及位置关系 ,补充人体调查资料 ,并为眶内侧壁血管结扎术及筛窦切除术提供解剖学参数。方法 :总结眶内侧壁血管神经孔的变化情况 ;采用游标卡尺分别测量左右两侧各孔间的相对距离并进行比较。结果 :穿经眶内侧壁的血管神经孔 ,二孔者所占比例为左 5 4 .12 % ,右 5 6.4 9% ,三孔者所占比例为左 4 2 .35 % ,右 4 1.18%四孔者所占比例为左 3.5 3% ,右 2 .33% ,未发现有单孔者。各孔间距离分别为Dacryon点—筛前孔 :左 17.73± 1.5 5mm ,右 17.5 2± 1.85mm ;筛前孔—筛后孔 :左 14.37± 1.4 6mm ,右 14.4 0± 1.76mm ;筛前孔—副筛动脉孔 :左 9.84± 2 .0 2mm ,右 9.76± 1.5 5mm。结论 :眶内侧壁血管神经孔的出现率以二孔最多 ,三孔次之 ,左右两侧对比 ,各孔出现率及两孔间距离统计学无显著差异。Dacryon点至筛前孔 ,筛前孔至筛后孔 ,筛前孔至副筛动脉孔的距离为手术止血提供参考依据。
Objective:To study the variations of VNFMWOs and the relations of their positions,supplement the human research data, and provide anatomical parameters for the ligation of the vessel in the medial wall of the oribit and ethmoidectomy.Method:Summarize the variations of the VNFMWOs,the vernier caliper was used to measure and compare the relative distances between every two foramens. Result: Among the 85 skulls, the percentages of two holes are 54.12%,56.49% whose VNFMWOs are on left and right sides respectively , three ones are 42. 35%, 41.18%respetively,no VNFMWOs was found to be one hole. The distances between anterior ethmoidal foramen and Dacryon point?and posterior ethmoidal foramen?and foramen of accessory ethmoidal artery on both sides respectively were 17.73 ±1.55mm(L), 17.52 ±1.85mm(R) ; 14. 37 ±1.46mm(L), 14.40 ±1.76mm(R);9.84 ±2.02mm(L),9.76 ±1.55mm( R) . Conclusion: In the VNFMWOs , two holes presented accounte for majority the next is three holes, There were no signifant statistical differences in the frequencies of the variations of the VNFMWOs and the distances between foramens on both sides, the distances above-mentioned could provide reference data for surgical hemostasis.
