Objective

To describe the use of a scrotal flap for covering perineal skin defects in dogs.

Study Design

Experimental study.

Animals

Male Beagles (n = 5).

Methods

A scrotal flap was created by making a U-shaped incision around the scrotum, with the base of the flap at its rostral border. Orchiectomy was performed through this incision and the scrotum was undermined from the underlying tissue. A small median longitudinal incision in the caudal aspect of the scrotum eliminated its curvature. A skin defect, comparable to the size of the scrotal flap, was created in the perineum extending from the caudal side of the scrotum toward the anus. The scrotal flap covered the defect and was sutured in place.

Results

By 5–7 days, all flaps had ∼27% necrosis on their caudal border. The necrotic area was surgically excised and the defect was covered completely again by the remaining healthy flap. One year after surgery, wound healing was normal and flap survival was complete, providing full coverage of the perineal skin defect.

Conclusion

A scrotal flap can be used to reconstruct perineal skin defects ventral to the anus.
