目的观察正常人群阴茎背神经数量及分布。方法采用38具成年男性(20~50岁)尸体的阴茎,对阴茎背神经、阴茎背深静脉和阴茎背动脉进行解剖观察,探查阴茎背神经的走形、分布及数量。结果阴茎背神经大多分布于阴茎背侧,其中各支大多平行分布。其数量为:7支1例,6支1例,5支6例,4支9例,3支14例,2支7例。38具尸体阴茎背神经数目平均值为(3.55±1.2)支。结论正常人阴茎背神经多为2支以上,呈平行分布。确定正常人群阴茎背神经数目和分布对原发性早泄患者术中保留阴茎背神经数目有指导意义。
Objective To observe the number and distribution of penis dorsal nerve in normal people. Methods Thirty-eight adult male (20-50 years old) cadavers were used to dissect the penis dorsal nerve, dorsal penile vein and penile dorsal artery to explore the shape, distribution and number of penis dorsal nerve. Results The dorsal penile nerve mostly distributed in the dorsal penis, of which the branches are mostly parallel. The number of cases was 7 in 1 case, 6 in 1 case, 5 in 6 cases, 4 in 9 cases, 3 in 14 cases and 2 in 7 cases. The average number of dorsal nerve of 38 corpses was (3.55 ± 1.2) branch. Conclusions The normal penis dorsal nerve is more than 2, which is parallel. Determine the number and distribution of normal dorsal penile nerve in patients with primary premature ejaculation in maintaining the number of dorsal penile nerve Guidance.
