摘要
目的:研究视交叉的解剖特点,进而为垂体肿瘤切除手术提供解剖学依据。方法:在20例成年男性头部标本上,对视交叉进行观察与测量。结果:视交叉前缘与鞍结节相距4.42±1.17mm,视交叉前缘与交叉前沟相距7.0±1.1mm,视交叉与镰状韧带颅前窝附着处后缘相距10.7±1.02mm,视交叉宽度为10.6±1.2mm,在出视神经管、入颅处,两侧视神经内缘相距14.8±1.9mm。结论:视交叉的解剖关系是垂体瘤手术成功与否的关键。
Objective: This study was designed to elucidate the anatomical characteristic of optic chiasm so as to provide anatomical basis on surgery on pituitary tumors. Methods:The optic chiasms were observed and measured in 20 adult male cadaveric head specimens. Results:The distance from anterior board of optic chiasm to tuberculum sellea was 4. 42±1. 17mm, the distance from anterior board of optic chiasm to sulcus prechiasmaticus 7. 0±1. 1mm,optic chiasm to falciform ligament 10. 7±1. 02mm,the transverse diameter of optic chiasm 10. 6±1. 2mm. At the cranial end ,the distance between bilateral optic nerves was 14. 8±1. 9mm. Conclusion: The anatomical characterises of optic chiasm was a key point in pituitary tumor resection.
