Anterior Perspective of the Anterior Scrotal Nerves

Description

Running inferior to the pubic symphysis, the anterior scrotal nerves are shown as fine cutaneous branches coursing across the anterior perineum toward the scrotal skin. Proximally, their fibers relate to the superficial inguinal region and the anterior pelvis, with the hip bones, sacrum, coccyx, and proximal femora providing bony orientation in an anterior perspective. Medial trajectories converge toward the root of the penis and anterior scrotum, while more lateral filaments track along the groin crease toward the upper medial thigh. Clinically, this is the territory where patients localize scrotal dysesthesia after inguinal hernia repair, orchiopexy, or other anterior groin approaches, and where precise distinction between the anterior scrotal branches and neighboring cutaneous nerves (ilioinguinal nerve, genital branch of the genitofemoral nerve, and anterior cutaneous branches of the pudendal nerve) guides diagnosis and targeted nerve blocks. Small-caliber nerves are easy to injure, entrap, or incorporate into mesh, and pain patterns often radiate along the inguinal canal and onto the anterior scrotum rather than the posterior perineum. Clean mapping of these filaments against the pelvic skeleton makes referral patterns easier to teach. Surgical educators can use this plate in general surgery and urology modules on groin anatomy, chronic post-herniorrhaphy pain, and scrotal sensory innervation, and it also fits well in anatomy lab prosections when the perineal branches are otherwise difficult to preserve. Medical publishers will find it useful for operative atlases and patient-facing explanations of why anterior scrotal numbness differs from pudendal neuralgia involving posterior scrotal sensation.
