摘　　要：在手术显微镜下解剖观察了30例成人头颅标本的海绵间窦。前间窦出现率93.3%,多呈三角形,主要位于鞍隔前缘与鞍前壁的硬脑膜转折处,与腺垂体周缘紧密相邻。下间窦出现率93.3%,多呈裂隙状,主要位于鞍底硬脑膜内,与腺垂体下面相贴。上述两窦特别宽大者各2例,为经蝶窦入路垂体切除术的禁忌症之一。后间窦最小,出现率53.3%,位于鞍隔后缘与鞍背的硬脑膜转折处,下邻垂体后叶上端。与垂体中间部相对处,垂体硬膜囊内层内凸成嵴,嵴内有垂体下动脉穿行。此嵴可作为垂体前、后叶的分界标志。The intercavernous sinuses of 30 adult specimens were examined under the operating microscope. Both the anterior intercavernous sinus(AIcS) and the inferior intercavernous sinus(ⅡcS)are present in 93.3% cases.The AIcS appears as a triangle canal in majority but the most ⅡcS as a split dural space.The AIcS relates closely to the peripheric border of the adenohypophysis and the ⅡcS contacts with the inferior surface of the adenohypophysis.The posterior intercavernous sinus(PIcS) is present in 53.3% cases and relates to the upper border of the neurohypophysis.
