背景
阴蒂是女性性反应的主要躯体感觉器官。了解其神经解剖和相关标志对于安全的生殖器手术至关重要。
目的
描述阴蒂背神经的远端走行及相关结构。
方法
对10具新鲜尸体的阴蒂进行了解剖。测量背神经、悬韧带、阴蒂体、阴蒂帽和阴蒂头。检查背神经的走行。
结果
阴蒂的背神经比预期的大，直径为2.0-3.2 mm，平均沿着它们在阴蒂体中的路线。在10例标本中，9例的背神经可追踪到阴茎头6 mm以内。它们深入到阴蒂浅筋膜，但浅于图尼卡白蛋白膜，位于10点到2点之间，并被阴蒂的深悬韧带分开。阴蒂体下降段从阴蒂头角到阴蒂头基部的平均长度为37.0 mm，从耻骨缘到深悬韧带的平均距离为37.7 mm。
结论
阴蒂体相当长，大部分位于阴蒂帽和阴阜下面的表面。阴蒂的背神经大而浅，终止于阴蒂头基部或附近。在阴蒂附近进行手术之前，了解这种解剖结构是至关重要的。
BACKGROUND
The clitoris is the primary somatosensory organ of female sexual response. Knowledge of its neural anatomy and related landmarks is essential for safe genital surgery.
OBJECTIVE
To describe the distal course of the dorsal nerves of the clitoris and associated structures.
METHODS
Clitorises of 10 fresh cadavers were dissected. Measurements of the dorsal nerves, suspensory ligament, clitoral body, clitoral hood, and clitoral glans were obtained. The course of the dorsal nerves was examined.
RESULTS
The dorsal nerves of the clitoris were larger than expected, ranging from 2.0-3.2 mm in diameter, on average, along their course in the clitoral body. In 9 of 10 specimens, the dorsal nerves could be traced to within 6 mm of the glans. They traveled deep to a superficial clitoral fascia but superficial to the tunica albuginea, were variably located between 10 and 2 o'clock, and were separated by the deep suspensory ligament of the clitoris. The mean length of the descending clitoral body, from the angle to the base of the glans, was 37.0 mm. The mean distance from the pubic rim to the deep suspensory ligament was 37.7 mm.
CONCLUSIONS
The clitoral body is substantial in length, mostly lying superficially under the clitoral hood and mons pubis. The dorsal nerves of the clitoris are large and superficial, terminating at or near the base of the clitoral glans. Knowledge of this anatomy is critical prior to performing surgery near the clitoris.
