摘要
目的:研究颞骨内乙状窦的显微解剖,为耳外科乳突入路手术提供解剖学依据。方法:模拟经乳突入路行耳外科手术,测量颞骨内乙状窦与周围结构间的距离。结果:乙状窦前板到外耳道后上棘距离为(13.28±1.87)mm,乙状窦-乳突表面最短距离为(5.16±0.73)mm,乙状窦上膝-外耳道后上棘距离为(17.85±1.62)mm,乙状窦下膝-外耳道后上棘距离为(19.68±2.11)mm,乙状窦前板到砧骨短脚中点、外半规管隆突的距离分别为(17.37±1.54)mm、(14.61±1.37)mm。结论:测量乙状窦外耳道后壁、乳突表面、半规管的距离对耳外科乳突入路手术有指导意义。
Objective：To study the relationship between sigmoid sinus and its adjacent structure in order to provide an anatomic basis for otochirurgia. Methods： The distance between sigmoid sinus and its adjacent structure was measured respectively based on the simulation of transmastoid approach. Results： The distance between the precingular plale of sigmoid sinus and the external auditory superameateal spine was （13.28 ±1.87）mm. The distance between sigmoid sinus and the surface of mastoid was （5.16 ± 0.73）mm. The distance between sigmoid sinus and external auditory superameatal spine was （ 17.85 ± 1.62） mm. The distance between sigmoid sinus inferior genu and external auditory superameatal spine was （ 19.68 ± 2.11 ） mm. The distance between sigmoid sinus and the short process of incus was （ 17.37 ± 1.54） mm. The distance between sigmoid sinus and the horizontal semicircular canal was （ 14.61 ± 1. 37） mm. Conclusions：It has guidance significance to measure the distance between sigmoid and the surface of mastoid, external auditory superameatal spine, and the other adjacent structure for the transmastoid approach.
