RESUMO
Introduction: There are many techniques to treat congenital concealed penis (CP). Skin resurfacing is the most difficult step in severe cases. We aim to show medium-term results of coronal sulcus-based triangular ventral mucosal flap (CBVMF) as a treatment of prepubertal severe CP, a recently reported technique. We aim to determine whether results are durable and if the technique is associated with persistent mucosal redundancy or with a permanent unequal penile color pattern. Methods: CP cases reconstructed with CBVMF were reviewed. Preoperative complaints, degree of motivation of the child/parent to surgery, satisfaction of parent/child with results, and surgical complications were described. Results: Seven patients (6 months to 6 years old) were treated with CBVMP. Two patients showed megaprepuce and another was submitted to a limited postectomy 3 years before. One family was not fully satisfied (expected "bigger penis"), but acknowledged that the penis was now well exposed. No child talked about the problem preoperatively, but all of the boys were fully satisfied with the results of the surgery and verbalized this in the interviews. Flap edema resolved after 3 months in all but one patient. The flaps assumed the color of penile skin in the medium term. Conclusions: CBMVP results were satisfactory. Serious complications did not occur. Flap edema does not persist in the medium term, and redundancy was not a problem. The color of the flap tended to evolve into a pattern similar to the penile skin.
