BACKGROUND
A landmark for the identification of the lingual artery (LA) through a transoral perspective can provide surgeons with an easy method to prevent and manage intraoperative bleeding during transoral approach to the base of tongue (BOT).
METHODS
Thirteen tongue and five head and neck specimens were dissected to identify and assess the reliability of the lingual point (LP) as a new landmark for the LA at BOT. The pathway of 42 LAs was radiologically evaluated; axial depth and vertical offset were measured for each LA.
RESULTS
Dissection study: a description of LP is provided; the LA was easily identified in all specimens (36/36 sides) using LP as a landmark. Radiologic study: the mean depth of the LA was 4.2 mm, the mean vertical offset was 1.3 mm.
CONCLUSIONS
LP is a simple and reliable landmark for identification of the LA, potentially helping surgeons to prevent and manage intraoperative bleeding.
背景
通过经口观察，确定舌动脉（LA）的一个标志，可以为外科医生提供一种简单的方法，以防止和管理经口入路舌根（BOT）手术中的术中出血。
方法
对 13 例舌和 5 例头颈部标本进行解剖，以确定和评估舌点（LP）作为 BOT 处 LA 的新标志的可靠性。对 42 条 LA 的通路进行了影像学评估；对每条 LA 的轴向深度和垂直偏移进行了测量。
结果
解剖研究：提供了 LP 的描述；使用 LP 作为标志，在所有标本（36/36 侧）中均容易识别 LA。影像学研究：LA 的平均深度为 4.2mm，平均垂直偏移为 1.3mm。
结论
LP 是识别 LA 的一种简单、可靠的标志，有可能帮助外科医生预防和管理术中出血。
