Which type of skin structure survives when harvesting a dermis graft?

When harvesting a dermis graft, sebaceous glands are among the skin structures that are likely to survive. Dermis grafts are primarily composed of the dermal layer of the skin, which contains these glands. Sebaceous glands are responsible for producing oil that helps to keep the skin moisturized and are situated within the dermis.

On the other hand, hair follicles typically do not survive in dermal grafts because they reside in the deeper layers that may not be preserved when only the dermis is harvested. Sweat glands, while located in the dermis, are more sensitive to the harvesting process, and therefore, their survival is not guaranteed. Blood vessels, although crucial for graft viability, do not remain intact as independent structures in the graft; rather, for a graft to survive, revascularization from the recipient site must occur post-operation.

Understanding the nature of each structure and its relationship to the dermal layer is essential for comprehending which components can endure the harvesting process. The presence of sebaceous glands within the harvested dermal graft contributes to its potential for integration and functionality when transplanted.
