This study was performed for knowledge about the vascular supply of the nasal fossa and a description of the site of division and number of branches of the sphenopalatine artery.
This study was performed on 10 fresh nonembalmed cadavers. Anatomic variations of nasal fossa arteries were studied.
First, 10 cephalic anatomic preparations were injected with red color latex into the right and left carotid arteries. Then, these specimens were sagittaly cut to dissect the sphenopalatine artery. Twenty vascularization cases were studied for the external branch of the sphenopalatine artery, and 10 cases were studied for the internal branch.
The principal observations were: 1. the sphenopalatine artery division is 18 times in the infratemporal fossa and twice in the nasal fossa; 2. the nasopalatine artery supplies blood to the lower part of the septum and its anterosuperior area; and 3. the vascularization of the external wall is via the sphenopalatine artery through the arteries of the meatus and conchae.
This study defines the vascular territories of the nasal fossa arteries and includes photographs of dissections.
本研究旨在了解鼻腔的血管供应，并描述蝶腭动脉的分支部位及分支数量。
本研究对10具未防腐处理的新鲜尸体进行。研究鼻腔动脉的解剖变异。
首先，向10个头部解剖标本的左右颈动脉注入红色乳胶。然后，将这些标本沿矢状面切开以解剖蝶腭动脉。对20例蝶腭动脉外支的血管分布情况进行研究，对10例内支的血管分布情况进行研究。
主要观察结果为：1. 蝶腭动脉在颞下窝分支18次，在鼻腔分支2次；2. 鼻腭动脉为鼻中隔下部及其前上区域供血；3. 鼻腔外侧壁的血管化是通过蝶腭动脉经鼻道和鼻甲的动脉实现的。
本研究明确了鼻腔动脉的血管分布区域，并包含解剖照片。
