改良阴茎延长术的解剖学研究和临床应用

Anatomic research and clinical application of modified penile elongation： a report of 205 cases

目的 对阴茎发育不良症患者,采用阴茎海绵体延伸术和脂肪瓣转移术充分延长短小的阴茎.方法 通过对男性会阴部结构的解剖学研究,了解阴茎悬韧带的厚度、阴茎脚剥离长度与稳定性的关系;通过离断阴茎浅、深悬韧带,并分离部分海绵体脚,使原固定于耻骨下支的阴茎海绵体充分分离,以使阴茎更为延伸;用含血运的脂肪瓣填塞耻骨前间隙,保证术后远期阴茎的有效长度.结果 2001至2009年采用上述方法行阴茎延长术205例,术前阴茎常态下平均长度4.26cm,勃起时平均长度8.13 cm,术后阴茎常态下平均长度8.63 cm,勃起时平均长度12.11 cm.结论 采用本方法可在不影响阴茎勃起时稳定性的前提下,使阴茎海绵体比以往的阴茎延长术多延伸1～2 cm,使之更加满足患者生理和心理上的需求.

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 cms. 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.
