(378) Predicting Penile Length Increase After Partial Release of the Suspensory Ligament in Cadaveric Adults

Introduction Introduction: Penile elongation surgery includes various procedures aimed at increasing penile length, with applications ranging from anatomical indications such as micropenis and post-surgical shortening in Peyronie’s disease to psychological concerns like penile dysmorphophobia. Suspensory ligament release is among the most frequently performed techniques. However, outcomes are variable, and complications-such as loss of penile angle, recurrence of shortening, and erectile dysfunction-remain concerns. There is no clear consensus on the optimal extent of ligament release. Objective Objective: To quantify the anatomical changes in penile length and pubopenal angle following 50% and 100% division of the suspensory ligament in cadaveric specimens, in order to inform surgical decision-making. Methods Methods: From May to August 2024, 34 male cadaveric specimens underwent staged division of the penile suspensory ligament. Measurements were taken at baseline, after 50% ligament division, and after complete (100%) division. Outcomes included gently stretched penile length (PLg, simulating flaccid state), fully stretched penile length (PLft, simulating erect state), and the pubopenal angle. Paired t-tests were used to analyze differences between the stages. Results Results: Mean PLg increased from 13.71 cm at baseline to 14.15 cm after 50% release, and to 14.56 cm after full release (p < 0.001 for both). Mean PLft increased from 14.42 cm to 14.90 cm and then to 15.33 cm, also statistically significant (p < 0.001). The pubopenal angle increased from 58.62° to 70.07° at 50% release, and to 79.37° after full release (p < 0.001). Comparisons between the 50% and 100% stages showed additional statistically significant gains in both PLg (p = 0.01) and PLft (p = 0.009). Conclusions Conclusion: Partial (50%) division may optimize both length gain and angle change, allowing for a more favorable position of the penis without compromising function. Further clinical studies are needed to validate these findings in live patients, particularly regarding erectile function, satisfaction, and long-term outcomes. Disclosure No
