Sphincterotomy proves to be highly successful in managing chronic anal fissures, with success rates generally surpassing 90%. This surgical method helps alleviate pain and facilitates healing by lowering tension in the anal sphincter, thereby improving blood circulation to the area affected by the fissure. The majority of patients report a significant reduction in symptoms and quick improvement after the surgery, making it a dependable treatment for those unresponsive to more conservative methods.
