An external anal sphincter cyst is a fluid-filled sac that forms near the external anal sphincter, a muscle responsible for controlling bowel movements. Understanding these cysts is crucial for early detection and effective management. This guide provides detailed information about external anal sphincter cysts, including their anatomy, types, causes, symptoms, diagnostic tests, treatments, surgeries, prevention methods, when to seek medical help, and answers to frequently asked questions.


Anatomy of the External Anal Sphincter

Understanding the external anal sphincter is essential to grasp how cysts form and affect this area.

Structure

  • Location: Surrounds the anal canal, extending from the pubis to the coccyx (tailbone).
  • Composition: Made of skeletal muscle, meaning it’s under voluntary control.
  • Function: Maintains continence by contracting to close the anus and relaxes during bowel movements.

Blood Supply

  • Arteries: Primarily supplied by the superior and inferior rectal arteries.
  • Veins: Drained by the superior and inferior rectal veins, which are part of the hemorrhoidal plexus.

Nerve Supply

  • Innervation: Supplied by the inferior rectal nerves, branches of the pudendal nerve.
  • Function: Controls muscle contractions and relaxations for continence.

Types of External Anal Sphincter Cysts

External anal sphincter cysts can vary based on their origin and characteristics. Here are the primary types:

  1. Anal Gland Cysts:
    • Formed from blocked anal glands.
    • Commonly develop into abscesses or fistulas if untreated.
  2. Pilonidal Cysts:
    • Occur near the coccyx.
    • Often contain hair and skin debris.
  3. Inclusion Cysts:
    • Result from skin trauma or surgery.
    • Trapped skin cells form a cyst.
  4. Sebaceous Cysts:
    • Originates from sebaceous glands.
    • Filled with oily substances like sebum.
  5. Epidermoid Cysts:
    • Formed from epidermal cells.
    • Contain keratin and dead skin cells.
  6. Steatocystoma:
    • Develops from sebaceous glands.
    • Typically larger and contain sebum.
  7. Abscess-Related Cysts:
    • Result from untreated infections.
    • Filled with pus and inflammatory materials.
  8. Tailgut Cysts:
    • Rare congenital cysts.
    • Originate from embryonic remnants.

Understanding the type of cyst is crucial for determining the appropriate treatment.


Causes of External Anal Sphincter Cysts

External anal sphincter cysts can develop due to various factors. Here are 20 common causes:

  1. Blocked Anal Glands: Prevents drainage, leading to cyst formation.
  2. Infections: Bacterial infections can cause abscesses and cysts.
  3. Trauma: Injury to the anal area can lead to cyst development.
  4. Surgical Procedures: Operations near the anal sphincter may result in cysts.
  5. Skin Infections: Conditions like cellulitis can lead to cyst formation.
  6. Ingrown Hairs: Particularly in pilonidal cysts near the tailbone.
