Which type of tissue separation is performed using blunt dissection?

• A. The tearing of tissue using fingers
• B. The slicing of tissue with sharp instruments
• C. The mechanical spreading of tissues without cutting
• D. The use of heat to separate tissues

Answer: (C)

Blunt dissection involves the mechanical separation of tissues without cutting, making this method ideal for gently separating structures or layers within the tissue. This technique is beneficial during surgical procedures where it's critical to minimize damage to surrounding tissues, such as blood vessels and nerves, which could occur with sharper dissection methods.

In blunt dissection, instruments or fingers are used to create a space between tissues by pushing or spreading them apart rather than incising or tearing, which is characteristic of other methods mentioned in the choices. For instance, tearing of tissue with fingers is more aggressive and could lead to unintended damage, while slicing tissues with sharp instruments is a precise cutting method that is not described as blunt dissection. The use of heat to separate tissues, such as through cauterization, is also a distinct technique unrelated to blunt dissection. Therefore, the defining feature of blunt dissection—the mechanical spreading of tissues—is captured accurately in the correct choice.
