Clinical Comparison of Scrotal Advancement Flap and Dorsal Transverse Preputial Island Flap for Severe Concealed Penis in Children: A Single-Center Retrospective Analysis

The island flap reliably covers large skin defects but is more complex and associated with edema and vascular risks. The choice of procedure should be individualized based on the patient's anatomy and the surgeon's expertise.
