据文献记载,供应扁桃腺的动脉有起于颈外动脉的咽升动脉,发自面动脉的腭升动脉和扁桃腺动脉,起于舌动脉的舌背动脉和腭降动脉的分支腭小动脉。这些动脉在经典解剖学中描述都很简单,它们的解剖学调查所见甚少,而扁桃腺手术是耳鼻咽喉科最常见的手术之一,据报导扁桃腺术出血的发生率在0.67%～3.6 According to the literature, the arteries supplying the tonsils have the pharyngeal ascending artery originating from the external carotid artery, the palatal ascending artery and the amygdala artery originating from the facial artery, the lingual dorsal artery originating from the lingual artery, and the branch palatal small artery originating from the palatal descending artery . The description of these arteries in classical anatomy is very simple, they have little insight into anatomical investigations, and tonsillectomy is one of the most common procedures for otolaryngology. The incidence of tonsil bleeding was reported to be 0.67% 3.6
