A<unk>  is a laceration of the skin and other soft tissue structures which, in women, separate the vagina from the anus.<unk> s mainly occur in women as a result of vaginal childbirth, which strains the perineum. It is the most common form of obstetric injury.<unk> s vary widely in severity. The majority are superficial and may require no treatment, but severe<unk> s can cause significant bleeding, long-term pain or dysfunction. A<unk>  is distinct from an episiotomy, in which the perineum is intentionally incised to facilitate delivery. Episiotomy, a very rapid birth, or large fetal size can lead to more severe<unk> s which may require surgical intervention.
