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:

  • Plastic Surgery
  • Surgical Education
  • Biomaterials

Background:

  • Ear reconstruction presents significant surgical challenges with often suboptimal patient outcomes.
  • Developing effective surgical training models is crucial for improving auricular reconstruction success rates.

Purpose of the Study:

  • To develop and evaluate a novel surgical training model for auricular reconstruction.
  • To assess the impact of a workshop-based instructional program on surgical trainees' skills.

Main Methods:

  • A workshop-based instructional program utilizing silicone costal cartilage models was implemented.
  • Trainees were divided into a workshop group (WG) and a non-workshop group (NWG), with the NWG later integrated due to frustration.
  • Frameworks were carved under varying supervision levels and assessed by blinded microtia surgeons using Likert and visual analog scales.

Main Results:

  • The workshop group initially scored higher in the first carving session (5.5 vs. 4.4).
  • All participants showed significant improvement between the first and second carving sessions (P ≤ 0.09) and first and third (P ≤ 0.05).
  • Sustained high scores without supervision were necessary, indicating the importance of extensive in vitro practice.

Conclusions:

  • An effective and applicable surgical training model and method can enhance the skills required for successful ear reconstruction.
  • The study highlights the necessity of supervised practice and iterative skill development in auricular reconstruction training.
