各种海马杏仁切除入路的外科解剖学

目的：探讨临床上各种海马杏仁核切除手术入路的优劣。方法：依据手术特点对１５例（３０侧）成人尸体头颅颞叶进行巨微解剖。结果：脉络膜裂是重要解剖间隙，其内有海马动态、脉络膜前动脉走行，海马动脉是海马结构的主要供血动脉；大脑后动脉走行于环池内，与海马旁回间有蛛网膜相隔。结论：现有的经颞叶外侧皮层、经侧层、经颞底等入路各有其优劣，而经颧弓颞叶入路是相对安全的入路。     

Macro-Micro-Anatomy of the Lingual Artery

The macro-micro-anatomy of the lingual artery of 25 adult cadavers wasstudied.The origin of the artery is rather concentrated and the greater cornu of thehyoid bone can be used as the indicator.The entrance of the artery into the hyoglossusmuscle is almost constantly along the posterior border of the muscle,where the artery issuperficially located and easily to be exposed,and has a constant relationship with thevein and hypoglossal nerve.Thus the lingual artery can be used as the artery of a recipientarea in case of tongue reconstruction.The deep lingual artery has two types ofbranches;the short ones mainly supply the muscles of tongue while the long ones mainlysupply the mucosa by forming a submucosal network.In the muscles of tongue,minutearterioles run tortuously along the muscular fibers with abundant anastomoses betweeneach other,but no anastomosis is found to cross over the rnidline of the tongue.Be-neath the mucosa,there is an arterial network spreading all over the whole tongue notlimited to one side.The relationship of the arterial architecture to the structure and thefunctions of the tongue and its clinical significance were discussed.
