Transverse facial vein

The transverse facial vein is a superficial venous structure located within the face, running transversely across the cheek, typically accompanying the transverse facial artery. It is responsible for draining blood from the lateral face and cheek region into the superficial temporal vein. Accurate identification and knowledge of its imaging characteristics are important in facial vascular assessment, surgical planning, and distinguishing vascular structures from pathology.

Synonyms

  • Transversalis vena facialis

  • Transverse vein of the face

Anatomy

  • Superficial vein located in the lateral facial region

  • Courses horizontally, parallel and inferior to the zygomatic arch

  • Usually accompanies the transverse facial artery

  • Drains into the superficial temporal vein

  • Receives tributaries from facial tissues and communicates with branches of the facial vein

MRI Appearance

 Proton Density (PD) Sequences

  • Appears as a well-defined, linear or slightly curvilinear structure

  • Shows low signal intensity due to flowing blood (“flow void” phenomenon)

  • Best visualized when oriented perpendicular to the imaging plane

Short Tau Inversion Recovery (STIR) Sequences

  • Demonstrates low signal intensity, similar to other veins

  • Suppression of surrounding fat increases contrast with adjacent facial tissues

  • Vein remains hypointense due to rapid blood flow, which suppresses signal

T1-Weighted Sequences

  • Appears as a hypointense (dark) tubular or linear structure

  • Surrounded by hyperintense subcutaneous fat

  • Absence of intraluminal signal due to the flow void effect of moving blood
