Goodsall's rule relates the external opening (in the perianal skin) of an anal fistula to its internal opening (in the anal canal). It states that if the perianal skin opening is posterior to the transverse anal line, the fistulous tract will open into the anal canal in the midline posteriorly, sometimes taking a curvilinear course.
A perineal tear is a laceration of the skin and other soft tissue structures which, in women, separate the vagina from the anus. Perineal tears mainly occur in women as a result of vaginal childbirth, which strains the perineum. It is the most common form of obstetric injury. [1] Tears vary widely in severity.

The predecessor of this procedure was sutured posterior rectopexy, in which the rectum was completely mobilized from the pelvic floor (i.e. including posterior and lateral surgical dissection of the rectum and sigmoid colon). [61] This caused autonomic nerve damage resulting in constipation and obstructed defecation after the surgery. [61]
This defect is also described as a groove in the anal canal wall and may occur after posterior midline fissurectomy or fistulotomy, or with lateral IAS defects. Rare causes of traumatic injury to the anal sphincters include military or traffic accidents complicated by pelvic fractures , spine injuries or perineal lacerations , insertion of ...

Based on the surface appearance, three lobes can be distinguished within the cerebellum: the anterior lobe (above the primary fissure), the posterior lobe (below the primary fissure), and the flocculonodular lobe (below the posterior fissure). These lobes divide the cerebellum from rostral to caudal (in humans, top to bottom).
