Summary:
Twenty two patients with gender dysphoria underwent neo-phalloplasties using a novel technique. Latissimus dorsi musculocutaneus
re-innervated free flap was used to allow voluntary rigidity of the neo-penis. From the first 22 patients, 18 have obtained motoric function
of reconstructed penis; the “paradox erection” was obtained. 14 patients came for examination after a follow-up period of mean
26.4 months. We evaluated the motility and shape changes of neo-phallus measuring its different size and dimension during relax and
muscle contraction. The range of neo-phallus length in relaxed position was between 7 and 17 cm (mean 12.2 cm), its circumference
in the same position had a range between 13 and 20 cm (mean 13.7 cm). All patients were able to contract the muscle with an average
length reduction of 3.08 cm and an average circumference enlargement of 4 cm. In this study, the dimensions and motility were
quantified demonstrating the neo-phallus function and size changes during sexual intercourse.
