在100具不同性别、年龄的尸体上，对咽部的血供来源、分布及变异进行了研究。已经证实，咽的喉部的前外侧分支由上级和下咽动脉的咽支供应血液。喉切除术中咽动脉入喉前的结扎，即。e.在咽分支从它们分叉之前，如传统的那样，导致这些部分的供应受限，并可能导致咽缝的分离。尽可能保留喉动脉干及其咽支。根据主要动脉来源（咽升动脉、甲状腺上级动脉和甲状腺下动脉），咽喉部的后壁分为三个区域。
: The sources, anastomoses and variations of bloodsupply of the laryngeal part of the pharynx were studied in 100 corpses of different sex and age. It has been established that the fronto-lateral divisions of the laryngeal part of the pharynx are supplied with blood by pharyngeal branches of the superior and inferior paryngeal arteries. Ligation of the pharyngeal arteries during laryngectomy prior to their entering the larynx, i. e. before the divergence of the pharyngeal branches from them, as conventional, causes restriction of supply of these parts and can contribute to disjunction of the pharyngeal suture. The trunks of laryngeal arteries with their pharyngeal branches should be preserved, if possible. The posterior wall of the laryngeal part of the pharynx is divided into three zones depending on the main arterial sources (the ascending pharyngeal, superior and inferior thyroid arteries).
