The sphenopalatine artery gives off two main branches: the posterior lateral nasal branch and the posterior septal branch. From 2007 to 2012 17 patients were treated with cauterization and/or ligature of the sphenopalatine artery with endonasal endoscopic approach. 90 nasal dissections were performed in 45 adult cadaveric heads. We evaluated the number of branches emerging from the sphenopalatine foramen and the presence of an accessory foramen. In the surgery group, we observed a single trunk in 76% of the patients (13/17) and a double trunk in 24% (4/17). We found an accessory foramen in four cases. We obtained a successful result in bleeding control in 88% of the cases. In the cadaver dissection group, 55 nasal cavities had a single arterial trunk (61%), 30 had 2 arterial trunks (33%) and in only 5 nasal fossae we observed 3 arterial trunks (6%). We were able to dissect four accessory foramina. We suggest that in most cases only one or two branches are found in the sphenopalatine foramen.
鼻外侧后支和鼻中隔后支。2007年至2012年，17例患者采用鼻内镜入路对蝶腭动脉进行烧灼和/或结扎治疗。在45个成人尸头中进行了90次鼻腔解剖。我们评估了从蝶腭孔发出的分支数量以及副孔的存在情况。在手术组中，我们观察到76%（13/17）的患者为单干，24%（4/17）的患者为双干。我们发现4例有副孔。88%的病例出血控制取得成功。在尸体解剖组中，55个鼻腔有单一动脉干（61%），30个有2个动脉干（33%），仅在5个鼻窝中观察到3个动脉干（6%）。我们能够解剖出4个副孔。我们建议，在大多数情况下，蝶腭孔中仅发现一或两个分支。
