What are typical treatments for an anal fissure?

Depends: An early anal fissure can be cured with local treatments such as pain medication, anti-inflammatory medication, and measures to prevent constipation straining and diarrhea. Older chronic fissures may need surgery such as an anal sphincter partial incision.

Conservative measure: High fiber diet, bulk laxatives and Diltiazem or nitroglycerine ointment. Typically these ointments must be mixed by a compounding pharmacist. Botulinum toxin is another option. Surgery is typically a lateral internal sphincterotomy. The division of a small portion of the distal internal anal sphincter.
