The sheep head is a cost-effective anatomical model for training functional endoscopic sinus surgery (FESS) skills. This versatile model is suitable for various surgical procedures across multiple specialties, offering a valuable learning resource for beginners.

Area of Science:

  • Otorhinolaryngology
  • Surgical Education
  • Anatomical Modeling

Background:

  • Functional endoscopic sinus surgery (FESS) requires specialized training.
  • An accessible and cost-effective anatomical model is needed for surgical skill development.
  • The ovine (sheep) head presents a potential alternative to traditional training models.

Purpose of the Study:

  • To evaluate the sheep head as a viable anatomical model for FESS training.
  • To assess participant satisfaction with the sheep head model for surgical simulation.
  • To examine the suitability of the ovine model for broader surgical training applications.

Main Methods:

  • Twenty-four participants with varying FESS experience performed procedures on sheep heads.
  • Participant satisfaction was assessed using a 14-item questionnaire (1-5 scale).

  • Statistical analysis included Shapiro-Wilk and Kruskal-Wallis tests.

    • Main Results:

    • Overall participant satisfaction scores were high across all experience groups (residents: 4.09, junior specialists: 4.00, senior specialists: 4.2).
    • No significant differences in satisfaction were found between the experience groups.
    • The ovine model demonstrated suitability for practicing manual skills and instrument use in FESS.

    Conclusions:

    • The sheep head is a successful and cost-effective model for learning and practicing FESS.
    • This anatomical model is adaptable for training in other otorhinolaryngology procedures and surgical fields like neurosurgery, ophthalmology, and plastic surgery.
    • Despite anatomical differences, the ovine head offers a valuable, resourceful training tool for surgical trainees.
