Summary:
Sulcus nervi dorsalis penis/clitoridis is a groove on inferior ramus of pubis and ventral surface of the body of pubis,
where dorsal nerve of penis in male and dorsal nerve and artery of clitoris in female run. Close relation of the dorsal
nerve of penis/clitoris and pubis, represented by the course of sulcus nervi dorsalis penis/clitoridis has a major impact
in surgical disciplines. Exact preparation of the dorsal nerve of penis is crucial in correct performance of conversion
of genitalia in patients with transsexualism, in reconstruction of posterior urethra, in hypospadia, during performance
of penile blockade during circumcision and in revascularization surgery of erectile dysfunction. The role of sulcus
nervi dorsalis penis in the Alcock’s syndrome is discussed. Similarly, it is advisable to take care of the dorsal nerve
of clitoris inside sulcus nervi dorsalis clitoridis during reduction clitoridoplasty in patients with adrenogenital syndrome
and during the insertion of transobturator vaginal tape. Injury of dorsal nerve of penis/clitoridis leads to hypestesia
or anestesia of glans penis/clitoridis. The injury of dorsal artery of clitoris leads to hematoma. It is possible to
use sulcus nervi dorsalis penis/clitoridis in sexing of isolated pubis from antropological or forensic purposes. Lateral
border of sulcus nervi dorsalis penis/clitoridis corresponds to vertical ridge and lateral border of sulcus nervi dorsalis
clitoridis to ventral arc – two parameters, which are part of the Phenice’s method for sexing of isolated pubis.
Key words:
dorsal nerve of penis, dorsal nerve of clitoris; pubis, ventral arc, vertical ridge, sex determination,
Alcock’s syndrome.
