From "silent teachers" to models

Abstract

For decades, embalmed cadavers have played an important role in teaching anatomy to the scientists and doctors of the future. Most anatomy departments use a traditional formaldehyde-based embalming method, but formalin embalming makes the bodies very rigid, which limits their usefulness for procedures other than dissection. A more recent embalming method developed by W. Thiel has allowed these "silent teachers" to take on a further role in applied anatomy research and teaching: to act as models for surgical training and medical research.

Figure 2. Thiel cadavers form a suitable model for laparoscopic procedures.

In laparoscopy the abdomen is filled with gas; instruments, a light source, and a camera are then inserted through small incisions while the surgeon follows the procedure on a screen. It takes significant training to develop the skills and dexterity needed for this, and Thiel cadavers are regularly used to train surgeons. Drawing by Emmanouil Kapazoglou.
