[Anatomic research and clinical application of modified penile elongation: a report of 205 cases].
OBJECTIVE
To investigate the application of penile cavernous bodies elongation combined with fat flap for the treatment of micro-penis.


METHODS
Anatomic study was performed to study the thickness of penile suspension ligaments and the relationship between the penile erection stability and the mobilization of cavernous bodies crus. The suspension ligaments were divided and cavernous bodies crus were partially mobilized, so as to release part of the cavernous bodies from inferior ramus of pubis. Then the penis was elongated sufficiently. Local fat flap was transposed to fill the front space of pubis to make sure the effective elongation of penis.


RESULTS
205 cases of micro-penis were treated. The average length of the penis was 4.26 cm in the static state, 8.13 cm in erectile state before operation. After operation, it increased to 8.63 cm in the static state, 12.11 cm in erectile state.


CONCLUSIONS
The cavernous bodies can be elongated 1-2 cm more with the modified method, while the stability of penile erection is not affected.
