Coronal sulcus-based ventral mucosal flap to help penile coverage in severe concealed penis

Area of Science:

• Urology
• Pediatric Surgery

Background:

• Congenital concealed penis (CP) presents surgical challenges, particularly in severe cases where skin resurfacing is difficult.
• The coronal sulcus-based triangular ventral mucosal flap (CBVMF) is a recently reported technique for CP reconstruction.

Purpose of the Study:

• To evaluate the medium-term durability and outcomes of the CBVMF technique for severe prepubertal CP.
• To assess the incidence of persistent mucosal redundancy and unequal penile color patterns post-surgery.

Main Methods:

• Retrospective review of seven prepubertal patients with severe CP treated with CBVMF.
• Assessment of preoperative complaints, parental/child satisfaction, and surgical complications.

Main Results:

• All seven patients achieved satisfactory exposure of the penis, with high satisfaction rates among the children.
• Flap edema resolved within three months in most cases, and flaps adopted a penile skin-like color over time.
• No serious complications or persistent mucosal redundancy were observed.

Conclusions:

• The CBVMF technique provides satisfactory and durable medium-term results for severe congenital concealed penis in prepubertal children.
• The procedure is associated with minimal complications and favorable cosmetic outcomes, including natural color matching and absence of redundancy.
