Endoscopic and microscopic video modules are effective for teaching middle ear anatomy

Area of Science:

• Medical education
• Otolaryngology
• Anatomy

Background:

• Middle ear anatomy is crucial for surgical training.
• Objective knowledge assessment is vital for evaluating educational interventions.
• Visual aids like video modules can improve anatomical understanding.

Purpose of the Study:

• To assess the effectiveness of video modules in improving middle ear anatomy knowledge.
• To compare the educational efficacy of endoscopic versus microscopic video recordings.

Main Methods:

• Medical students and residents were randomized into two groups.
• One group viewed an endoscopic video module, the other a microscopic video module.
• Knowledge was assessed using a pre- and post-intervention test.

Main Results:

• Both endoscopic and microscopic video modules significantly improved test scores.
• The mean score increase was 12.3% for the endoscopic group and 11.7% for the microscopic group.
• No significant difference in posttest performance was found between the two groups when controlling for pretest scores.

Conclusions:

• Video modules are effective for short-term knowledge acquisition of middle ear anatomy.
• Endoscopic and microscopic video modalities demonstrate comparable educational utility.
• Larger studies are needed to determine optimal teaching modalities.
