What condition results from injury to the nerves in the ischioanal fossa?

Sphincteric incontinence occurs when there is damage to the nerves that control the anal sphincter muscles, which are crucial for maintaining continence. Injury to the nerves in the ischioanal fossa can directly impact the function of these sphincters. The ischioanal fossa is the space in the lower part of the pelvis that contains structures like the external anal sphincter and associated nerves, particularly the inferior rectal nerve, which is responsible for innervating the external anal sphincter. When these nerves are compromised, the result can be a lack of coordination and control over the sphincter, leading to unintentional loss of stool—what is referred to as sphincteric incontinence. Understanding the relationship between nerve injury and sphincter function is essential for diagnosing and managing such conditions effectively.
