External Anal Sphincter Diseases

Anatomy? of the External Anal Sphincter

Structure

The external anal sphincter is a ring of muscle located around the anus?. It controls the release of stool from the rectum?, helping maintain continence. Unlike the internal sphincter, which is involuntary, the external sphincter is under voluntary control, meaning you can consciously control it.

Blood Supply

The external anal sphincter receives blood through the inferior rectal arteries?, which branch from the internal pudendal arteries. Adequate blood flow is essential for the muscle’s function and overall anal health.

Nerve Supply

The external anal sphincter is innervated by the pudendal nerve. This nerve provides the necessary signals for muscle contraction and relaxation, allowing control over bowel movements.

Types of External Anal Sphincter Diseases

External anal sphincter diseases can vary in nature and severity. Some common types include:

1. Anal Fissures: Small tears in the lining of the anus.
2. Anal Abscesses: Infected cavities filled with pus? near the anus.
3. Fistulas: Abnormal connections between the anal canal and the skin.
4. Hemorrhoids?: Swollen blood vessels in the anal area.
5. Muscle Spasms: Involuntary contractions of the sphincter muscle.
6. Injuries: Trauma? to the anal area affecting the sphincter.
7. Neurological Disorders: Conditions affecting nerve control of the sphincter.
8. Infections: Bacterial? or viral? infections impacting the sphincter.
9. Inflammatory Diseases: Such as Crohn’s disease affecting the anal area.
10. Tumors: Growths that may impinge on the sphincter.

Causes

External anal sphincter diseases can result from various factors. Here are 20 common causes:

1. Chronic Constipation?: Straining during bowel movements can damage the sphincter.
2. Childbirth: Vaginal delivery may cause trauma to the anal muscles.
