鼻内镜下经上颌窦蝶腭动脉结扎术的应用解剖学

Applied anatomy for endoscopic transmaxillary-sinus sphenopalatine artery ligation

【目的】为鼻内镜下经上颌窦蝶腭动脉结扎提供解剖学资料。【方法】对固定的成人尸体上颌动脉翼腭部进行显微外科解剖,观察腭降动脉与蝶腭动脉的关系,并测量腭降动脉和蝶腭动脉的外径及长度。【结果】蝶腭动脉为上颌动脉的直接延续,蝶腭动脉外径平均为(1.79±0.34)mm,腭降动脉的外径平均为(1.48±0.27)mm,长度平均为(8.28±2.49)mm。【结论】腭降动脉是经上颌窦鼻内镜下定位蝶腭动脉重要解剖标志。

【Objective】To provide anatomical data for endoscopic teansmaxillary-sinus sphenopalatine artery ligation.【Methods】15 skulls(30 sides) of corpse were microsurgical dissected to observe the relation between descending palatine artery and sphenopalatine artery.【Results】The descending palatine artery was located inferior to the sphenopalatine artery,the diameters of descending palatine artery was(1.48±0.27)mm and sphenopalatine artery(1.79±0.34)mm and the length of descending palatine artery was(8.28±2.49)mm.【Conclusion】It indicates that the descending palatine artery is a helpful and reliable landmark for endoscopically locating the sphenopalatine artery.
