Ischioanal Fossa Disorders

The ischioanal fossa, also known as the ischiorectal fossa, is a triangular-shaped space located on each side of the anal canal. Disorders involving the ischioanal fossa can lead to discomfort, pain, and other complications. This guide explains the anatomy, causes, symptoms, diagnostics, treatments, and prevention in simple language.

Anatomy of the Ischioanal Fossa

1. Structure

The ischioanal fossa is an anatomical space in the pelvic region, located between the pelvic diaphragm and the skin of the perineum. It’s shaped like an inverted pyramid with the following boundaries:

• Base: The skin around the anal opening.
• Apex: The point where muscles of the pelvic floor meet.
• Lateral Walls: Formed by the obturator internus muscle and fascia.
• Medial Wall: Consists of the levator ani muscle, which supports the pelvic floor.
• Posterior Wall: Formed by the sacrotuberous ligament and the gluteus maximus muscle.

2. Blood Supply

The ischioanal fossa is supplied by:

• Inferior Rectal Artery: A branch of the internal pudendal artery.
• Inferior Gluteal Artery: Supplies blood to the surrounding muscles and tissues.

3. Nerve Supply

The nerves that supply the ischioanal fossa include:

• Inferior Rectal Nerves: Branches of the pudendal nerve that control the muscles around the anus.
• Perineal Nerves: Provide sensation to the perineum.

Types of Ischioanal Fossa Disorders

Several disorders can affect the ischioanal fossa. Here are some common types:

• Abscesses: Pockets of pus that form due to infection in the fossa.
• Fistulas: Abnormal tunnels between the anal canal and the skin.
• Cellulitis: Inflammation and infection of the soft tissues.
• Perianal Hematoma: Blood accumulation due to trauma or pressure.
• Tumors: Rarely, benign or malignant tumors can develop in the ischioanal fossa.
• Fungal Infections: Can cause discomfort and swelling in the area.
