Area of Science:

  • Anatomy
  • Surgical Techniques

Background:

  • Vestibulocochlear organs are anatomically complex and difficult for medical students to dissect and visualize due to their location within the petrous part of the temporal bone.
  • Traditional dissection methods present challenges in gross anatomy classes, hindering effective learning of these delicate structures.

Purpose of the Study:

  • To develop and evaluate a time-saving and fail-safe dissection procedure for vestibulocochlear organs.
  • To enhance medical students' ability to visualize and dissect the vestibulocochlear organs during gross anatomy courses.

Main Methods:

  • A hand-held hobby router was employed to dissect nine en bloc human temporal bone samples.
  • The optimal dissection technique involved removing the roofs of the external acoustic meatus, tympanic cavity, and internal acoustic meatus.
  • The procedure's effectiveness was assessed via a survey of 121 cadavers (242 sides) focusing on observation ratios.

Main Results:

  • The selected hobby router dissection method was completed within two 4.5-hour dissection classes.
  • Student observation ratios for key structures like the chorda tympani and semicircular canals significantly improved between 2013 and 2016.
  • The technique of removing the external acoustic meatus, tympanic cavity, and internal acoustic meatus roofs proved most effective.

Conclusions:

  • The hobby router dissection technique offers a practical and efficient solution for teaching vestibulocochlear anatomy.
  • This method enhances student learning outcomes by improving visualization and dissection success rates within limited class time.
  • The procedure represents a valuable advancement for gross anatomy education of the temporal bone and its contents.
