Paravaginal delivery is extremely rare. Perineal delivery was reported in just fewer than 100 cases, most of which occurred in the 19th and early 20th century. ⋯ The baby delivered through a lateral vaginal tear and through the labia majora with little trauma to the underlying tissues. Explanations of how this could have happened and how to prevent it are discussed.
