To describe the course and variation of the dorsal nerve of the clitoris (DNC) to better define its anatomy in the human adult before embarking on therapeutic strategies in this region of the body and as an aid to surgeons to help avoid iatrogenic injury to the DNC during vaginal surgical procedures.
Six human female cadavers of variable body weights were sectioned. A vertical midline incision from the base of the clitoris extending toward the direction of the umbilicus was made. The DNC was identified by dissecting out the fascia, fat, and muscles around it. The anatomy of the nerve was noted bilaterally.
Distally, the DNC pierced the perineal membrane lateral to the external urethral meatus. It traversed along the bulbospongiosus muscle before traversing posterior to the crura. The DNC reappeared, hooking over the crura to lie on the anterolateral surface of the body of the clitoris, before dividing into 2 cords and terminating short of the tip of the glans clitoris.
The results of this study have demonstrated the unique anatomy of the distal part of the DNC. Knowledge of the anatomy of the DNC, which was consistent for all the cadavers, is important so that surgeons can avoid potential iatrogenic injuries to this structure.
描述阴蒂背神经（DNC）的走行和变异情况，以便在开展该身体区域的治疗策略之前更好地明确其在成年人体内的解剖结构，并帮助外科医生在阴道手术过程中避免对阴蒂背神经造成医源性损伤。
对6具体重各异的成年女性尸体进行解剖。在阴蒂基部做一条垂直的中线切口，并向脐部方向延伸。通过解剖其周围的筋膜、脂肪和肌肉来识别阴蒂背神经。对双侧神经的解剖结构进行记录。
在远端，阴蒂背神经穿经尿道外口外侧的会阴膜。它先沿球海绵体肌走行，然后在阴蒂脚后方穿行。阴蒂背神经再次出现，绕过阴蒂脚，位于阴蒂体的前外侧表面，然后分成两条分支，在阴蒂头尖端附近终止。
本研究结果显示了阴蒂背神经远端独特的解剖结构。了解阴蒂背神经的解剖结构（所有尸体的情况均一致）十分重要，这样外科医生就能避免对该结构造成潜在的医源性损伤。
