Overview
Sulcus nervi dorsalis penis/clitoridis is a groove on the inferior branch of pubic bone and the ventral surface of the body of the pubic bone, where the dorsal nerve of penis in the male and the dorsal nerve and the artery of clitoris in the female run. The close relation between the dorsal nerve of penis/clitoris and the pubic bone, represented by the course of sulcus nervi dorsalis penis/clitoridis is of major significance in surgical disciplines. Careful and sparing preparation of the dorsal nerve of penis is crucial in correct performance of conversion of genitalia in transsexual patients, in posterior urethral reconstruction, in hypospadia, during the performance of penile blockade during circumcision and in revascularization surgery in erectile dysfunction. The role of sulcus nervi dorsalis penis in Alcock´s syndrome is discussed. Similarly, it is advisable to handle carefully the dorsal nerve of the clitoris inside sulcus nervi dorsalis clitoridis during reduction clitoridoplasty in patients with adrenogenital syndrome and during the insertion of the transobturator vaginal tape. Injury to the dorsal nerve of the penis/clitoridis leads to hypesthesia or anesthesia of glans penis/clitoridis. Injury to the dorsal artery of the clitoris leads to a hematoma.
Key words:
dorsal nerve of penis, dorsal nerve of clitoris, pubic bone, Alcock's syndrome
