Area of Science:

  • Otorhinolaryngology
  • Anatomy
  • Biomedical Engineering

Background:

  • The stapes, a small bone in the middle ear, transmits sound vibrations.
  • Accurate dimensional data of the stapes superstructure is essential for otologic surgery and biomechanical modeling.

Purpose of the Study:

  • To precisely measure and document the dimensions of the human stapes superstructure.
  • To provide a detailed anatomical reference for the stapes head, neck, and crura.

Main Methods:

  • Ten human stapes were obtained from fresh temporal bones.
  • Detailed measurements of various stapes superstructure components were performed using calipers.

Main Results:

  • Stapes head diameter: 1.14 mm (parallel) and 0.83 mm (perpendicular).

  • Neck width: 1.18 mm (parallel) and 0.64 mm (perpendicular).
  • Crus widths ranged from 0.51 mm to 0.65 mm.

    • Conclusions:

    • This study provides comprehensive dimensional data for the human stapes superstructure.
    • These anatomical measurements can aid in the design of prostheses and surgical techniques.
