摘　　要：目的 :寻找乙状窦前入路中骨性半规管的轮廓化方法和内淋巴囊的识别标志。方法 :10具成人头颅湿标本在显微镜下进行岩骨后部的显微解剖。结果 :上半规管弓气房位于外半规管隆起上方 ,上半规管内侧 ,后半规管位于迷路下气房上方、前庭导水管外口外侧。内淋巴囊位于前庭导水管外口内侧。结论Aim:To seek the landmark of bony semicircular canal and inner lymph sac. Methods:Ten adult cadaver skulls were dissected under microscope.Results: Air cells of superior semicircular canal (SSC) is located at superior arcuate eminence, and posterior semicircular canal (PSC) is located at superior to the infralabyrintheine air cells and lateral to the external aperture of aqueduct of vestibule. Conclusion:It is more safe to use the air cells of SSC and the infralabyrinthine air cells as landmark to expose the bony semicircular canal.
