Labia Minora Necrosis

Pathophysiology

Structure of Labia Minora

The labia minora are the smaller, inner folds of skin surrounding the vaginal opening. They protect the more delicate structures inside, such as the clitoris, urethra?, and vaginal canal. Composed of soft tissue, they contain blood vessels, nerves, and glands that keep the area moist and sensitive.

Blood Supply

The labia minora receive blood primarily from the vulvar arteries?, which branch from the internal pudendal artery?. Adequate blood flow is essential for maintaining healthy tissue and healing any injuries or infections.

Nerve Supply

Nerve endings in the labia minora provide sensitivity and play a role in sexual arousal and pleasure. The pudendal nerve is the main nerve responsible for sensation in this area.

How Necrosis Occurs

Necrosis in the labia minora happens when blood flow is significantly reduced or blocked, leading to tissue death. Causes can include severe? infections, trauma?, vascular diseases, or complications from medical treatments.
