[Arterial blood supply to the laryngeal part of the pharynx].

[Article in Russian]

Abstract

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).
