Abstract

BACKGROUND

The study investigated the anatomy of the retroauricular lymph node (LN) flap and evaluate its surgical feasibility as a new donor site for a free LN flap in lymphedema surgery.

METHODS

Twelve adult cadavers were examined. The course and perfusion of the anterior auricular artery (AAA) and the location and sizes of the retroauricular LNs were studied.

RESULTS

The AAA was available in 87% and absent in 13% specimens. The AAA's origin had a mean vertical distance of 12.2 ± 6.9 mm and a mean horizontal distance of 19.1 ± 4.2 mm from the superior attachment of the ear. The mean diameter of the AAA was 0.8 ± 0.2 mm. The mean number of LN per region was 7.7 ± 2.3, with an average LN size of 4.1 ± 1.9 × 3.2 ± 1.7 mm. The LN were categorized into anterior (G1) and posterior (G2) groups, with a total of 59 and 10 LN, respectively. In a cluster analysis, three LN clusters could be detected across the anterior group (G1).

CONCLUSIONS

The retroauricular LN flap is a delicate but feasible flap with reliable anatomy, containing a mean of 7.7 LNs.

摘要

背景

本研究调查了耳后淋巴结（LN）皮瓣的解剖结构，并评估其作为淋巴水肿手术中游离LN皮瓣新供区的手术可行性。

方法

对12具成年尸体进行检查。研究了耳前动脉（AAA）的走行和灌注情况以及耳后LN的位置和大小。

结果

87%的标本中有AAA，13%的标本中无AAA。AAA的起源距耳上附着点的平均垂直距离为12.2±6.9mm，平均水平距离为19.1±4.2mm。AAA的平均直径为0.8±0.2mm。每个区域LN的平均数量为7.7±2.3个，LN的平均大小为4.1±1.9×3.2±1.7mm。LN分为前组（G1）和后组（G2），分别有59个和10个LN。在聚类分析中，在前组（G1）中可检测到三个LN簇。
