The retroauricular lymph node (LN) flap shows reliable anatomy and feasibility for lymphedema surgery. This study details its anatomical characteristics, identifying a mean of 7.7 LNs per flap.

Area of Science:

Anatomy
Microsurgery
Lymphedema Research

Background:

Investigated the anatomy of the retroauricular lymph node (LN) flap.
Evaluated its surgical feasibility as a donor site for free LN flap in lymphedema surgery.

Purpose of the Study:

To explore the anatomical feasibility of the retroauricular lymph node flap for lymphedema treatment.
To detail the vascular supply and lymph node characteristics of this potential new donor site.

Main Methods:

Dissection of 12 adult cadavers.
Analysis of the anterior auricular artery (AAA) course and perfusion.
Identification and measurement of retroauricular lymph nodes (LNs).

The anterior auricular artery (AAA) was present in 87% of specimens.

A mean of 7.7 lymph nodes (LNs) were identified per region, with an average size of 4.1×3.2 mm.

Three distinct lymph node clusters were detected in the anterior region.

Conclusions:

The retroauricular LN flap is anatomically reliable and surgically feasible.
This flap offers a viable option for lymphedema surgery.
Further research can explore its clinical application in free flap reconstruction.
