The embedding of ossicular chain specimens in plastic

Area of Science:

• Anatomy
• Medical Education
• Materials Science

Background:

• Traditional anatomical teaching materials, such as human auditory ossicles, are prone to degradation.
• Effective visualization and long-term preservation of delicate anatomical structures are crucial for medical education.

Purpose of the Study:

• To develop a novel, durable teaching model of human auditory ossicles for medical students.
• To enhance the observational clarity and longevity of anatomical specimens.

Main Methods:

• Human auditory ossicles were preserved using a 30% hydrogen peroxide solution.
• The ossicles were embedded in a heat- and chemical-resistant plastic, shaped into a 5 cm ball, and polished.

Main Results:

• The embedded ossicles demonstrated permanent preservation due to the resistant plastic matrix.
• The plastic embedding provided a magnifying effect, enhancing student observation during lectures.

Conclusions:

• This method offers a permanent and easily observable teaching tool for human auditory ossicles.
• The developed model significantly improves the quality and accessibility of anatomical education for medical students.
