What does the dermatofasciectomy procedure involve?

1. Removal of the fascia with a muscle graft

2. Fascia excision with subsequent skin grafting

3. Suture repair of the overlying skin

4. Amputation of the affected digit

The correct answer is: Fascia excision with subsequent skin grafting

The dermatofasciectomy procedure is primarily characterized by the excision of the fascia along with the skin covering it. This surgical intervention is often employed to address conditions like chronic infections or extensive scarring where both the skin and subcutaneous tissues may be compromised. In this process, once the fascia is excised, a skin graft is typically used to cover the defect created by the removal of the skin and fascia. This combination of excision and grafting is crucial as it aids in promoting better healing and function in the affected area. In contrast, the other options do not accurately represent the core aspects of dermatofasciectomy. Removing the fascia with a muscle graft involves a different approach, focusing more on reconstruction with muscle, rather than simply addressing the dermal and fascial layers with a skin graft. Suture repair of the overlying skin represents a simpler closure method that does not involve the excision of fascia. Lastly, amputation pertains to the complete removal of a digit, which deviates from the aims and techniques used in dermatofasciectomy, where the focus is on preserving as much of the anatomical structures as possible while treating pathological conditions.
