Penile skin length can be predicted before frenuloplasty during routine circumcision

One of the restricting factors for surgical treatment of congenital anatomical pathologies of the penis is the skin structure. Thanks to its structure, the penis is a flexible organ structure, and the treatment can be completed without the need for a free tissue graft. Length changes are obtained on the ventral side of the penis by frenuloplasty.

Our study aims to attain an objective formula that could noninvasively predict these changes on the ventral side before the procedure.

In our study, 52 patients who were admitted for routine religious circumcision were included, and penile ventral and dorsal skin and inner mucosa lengths were measured before and after frenuloplasty, which is a part of the normal routine circumcision procedure and performed via the "pull and burn" method. Stitches were done to prevent scar formation in the frenuloplasty area. The results were used to estimate the length changes to be obtained on the ventral side by performing a regression analysis of the patient's weight, height, ventral and dorsal inner mucosa, and outer skin lengths. Result: Following frenuloplasty, an increase was detected in the ventral surface ranging from 20% to 177%. This increase was found to be predictable with 62.5% precision (P < 0.01) using the formulation established by assessing the ventral inner mucosa length from pre-procedure values. No significant result was determined in the regression analysis of the patients' other measurements (P > 0.05).

Penile length changes that would occur following frenuloplasty can be calculated using a noninvasive method. Frenuloplasty, which would be performed without any vascular change, could be helpful in the surgical planning of some penile surgeries. More studies should be conducted on older boys, in anatomic deviations, and moreover, to establish a reliable formulation.
