Area of Science:

  • Anatomical modeling
  • Surgical simulation
  • 3D visualization

Background:

  • Cleft palate anatomy presents significant challenges for surgical appreciation.
  • Accurate anatomical understanding is crucial for effective cleft palate repair.

Purpose of the Study:

  • To develop comprehensive 3D models of cleft palate anatomy.
  • To provide a surgical perspective for cleft palate repair.

Main Methods:

  • Utilized cadaver dissections, Visible Human Project data, literature review, and surgical expertise.
  • Segmented CT scans using 3D Slicer for bony anatomy.
  • Employed ZBrush and Blender for soft tissue and model refinement.

Main Results:

  • Generated a 3D model of a Veau 2 cleft palate with detailed hard palate and skull base.
  • Modeled key muscles including superior constrictor, buccinator, palatopharyngeus, palatoglossus, and tensor veli palatini.
  • Incorporated layers such as seroglandular/adipose tissue, periosteum, vasculature, and mucosa.

Conclusions:

  • A realistic and accurate 3D computer model of cleft palate anatomy was successfully developed.
  • The model offers a clear representation of anatomy vital for surgeons performing cleft palate repair.
