Anatomy of the Ear01:16

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Area of Science:

  • Otolaryngology
  • Surgical Education
  • Anatomical Modeling

Background:

  • Human cadaveric specimens are the gold standard for ear surgery training but are becoming scarce.
  • Ethical considerations also limit cadaver use.
  • Alternative biological models are needed for surgical training.

Purpose of the Study:

  • To evaluate the sheep head as an anatomical model for ear surgery (ES) training.
  • To assess participant satisfaction with the sheep head model for ES procedures.

Main Methods:

  • Twenty-one otolaryngology participants (residents, junior specialists, senior specialists) performed procedures on sheep heads.
  • A 11-item satisfaction questionnaire (scale 1-5) was administered post-procedure.
  • Kruskal-Wallis test analyzed satisfaction differences between experience groups.

Main Results:

  • No statistically significant differences in satisfaction were found between the three experience groups (p > 0.05).
  • Average satisfaction scores were high across all groups: residents (4.09 ± 0.54), junior specialists (4.00 ± 0.55), and senior specialists (4.2 ± 0.77).

Conclusions:

  • The sheep head is a suitable anatomical model for practicing ear surgery skills.
  • It effectively facilitates learning manual dexterity and instrument handling for otolaryngology trainees.
