Facial Arterial Perforator Measurements from Cadaver Micro-CT Imaging

Seven cadavers (14 hemifaces) were examined using micro-computed tomography combined with dissection to map arterial perforators in the face. The dataset records the number, diameter, and topographic distribution of 134 perforators from seven major arteries. Ji–Young Son published this data on figshare in May 2026 under a CC-BY-4.0 license.

Use Cases

• Design facial flap transplantation procedures based on perforator distribution patterns relative to anatomical landmarks.
• Analyze the prevalence and average diameter of perforators from specific arteries like the facial artery main trunk.
• Create heatmaps of perforator coordinate density, as referenced for the lateral nasal branch of the facial artery.
• Use the subnasale horizontal line as a reference in surgical planning, as suggested by distinct distribution patterns.

Strengths

• Includes data from 14 hemifaces across seven cadavers, providing bilateral anatomical perspective.
• Focuses on perforators with a diameter of 0.5 mm or greater, a clinically relevant threshold for flap transplantation.
• Provides quantitative metrics including total count (134 perforators), prevalence (100% for main facial artery trunk), and average per hemiface (3.4).
• Maps locations based on standardized anatomical planes (Frankfort horizontal plane, vertical line through porion).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a small sample of seven cadavers with a mean age of 80.3 years, which may limit generalizability.
