Visualization of Penile Suspensory Ligamentous System Based on Visible Human Data Sets

Area of Science:

• Anatomy
• Medical Imaging
• Surgical Technology

Background:

• Understanding the penile suspensory ligamentous system is crucial for penis-lengthening surgery.
• Previous anatomical descriptions may lack detailed 3D visualization.
• Visible Human datasets offer a valuable resource for anatomical study.

Purpose of the Study:

• To illustrate and describe the anatomical features of the penile suspensory ligamentous system using 3D visualization.
• To explore the penis suspensory mechanism.
• To provide insights for improving penis-lengthening surgery.

Main Methods:

• Utilized cross-sectional images from Chinese Visible Human (CVH-1, CVH-3) and Visible Human Male (VHM) datasets.
• Segmented the penile suspensory ligamentous system and adjacent structures.
• Reconstructed 3D models and compared with MRI findings.

Main Results:

• Detailed morphological features of the fundiform, suspensory, and arcuate pubic ligaments were elucidated.
• The fundiform ligament is superficial fibro-fatty tissue originating from Scarpa's fascia.
• The suspensory and arcuate pubic ligaments are dense fibrous tissues originating from the pubic symphysis and attaching to the corpora cavernosa.

Conclusions:

• 3D models derived from Visible Human data effectively clarify penile suspensory ligamentous system anatomy.
• This anatomical clarity can significantly contribute to advancements in penis-lengthening surgical procedures.
• The study highlights the utility of 3D visualization in anatomical research for surgical improvement.
