颞下窝的显微解剖与手术学意义

Microsurgical Anatomy and Operative Significances of the Infratemporal Fossa

目的对颞下窝进行显微解剖并分析其手术学意义,为相关手术入路和影像学研究提供显微解剖学资料。方法利用8具经福尔马林固定的成人头颅湿标本和5具成人头颅干标本,在显微镜下对颞下窝及其周围的骨性结构、神经和血管进行解剖,从多角度进行观察和拍照记录,对解剖结果进行详细描述。结果颞下窝是由骨性结构包围的颅外间隙,位于中颅窝下方,并与上颌窦、翼腭窝、咽旁间隙等区域毗邻并交通;颞下窝内的主要结构包括翼内肌、翼外肌、下颌神经和上颌动脉及其分支以及翼丛静脉;以上结构的位置和走行具有一定的规律。结论精细的显微解剖操作和观察有助于全面掌握颞下窝的解剖知识,从而指导相关颅底外科的显微手术。

Objective To study the microsurgical anatomy and operative significances of the infratemporal fossa.Methods Eight adult formalin-fixed cadaver specimens and five dry skull specimens were examined.The bony structures and soft tissues of infratemporal fossa were dissected and examined step by step on both sides of each specimen under surgical microscope.After accomplishment of each key step,photographs were taken.Results Infratemporal fossa is an extracranial space enclosed by bony structures.It is located un...
