Area of Science:

  • Otolaryngology
  • Surgical Education
  • Anatomical Modeling

Context:

  • Human cadaver temporal bones are the traditional training standard for middle ear surgery but face availability issues.
  • A calcium sulfate-based temporal bone model was developed in collaboration with 3di company Jena, Germany.
  • This ceramic model addresses the limitations of cadaveric specimen accessibility for surgical training.

Purpose:

  • To evaluate the efficacy of a novel calcium sulfate-based temporal bone model for surgical training.
  • To assess the model's utility for teaching complex temporal bone anatomy and surgical procedures.
  • To provide an alternative training resource for otolaryngology residents and surgeons.

Summary:

  • Ceramic temporal bone specimens were utilized in a mastoid surgery course for beginner surgeons in Tanzania.

  • Participants employed chisel and carving techniques due to the absence of drills.
  • Procedures included exposing critical structures like the sigmoid sinus, facial nerve, labyrinth, dura, jugular bulb, and internal carotid artery.

    • Impact:

    • The calcium sulfate temporal bone model facilitated excellent understanding of 3-dimensional anatomy and the relationship between key structures.
    • Good exposure of the dura, facial nerve, and major blood vessels was achieved.
    • While finer structures like the labyrinth were challenging to expose, the model proved highly beneficial for beginners and in resource-limited settings.
