-
A fissure or cleft in the lip, occurring normally in the hare and various fishes, and as a congenital deformity in children, due in the latter case to an imperfect local development of the tissues. It usually occurs in the upper lip, and is generally dependent on a defective or delayed union of the superior maxilla, or a deficient development of the premaxillary bones.
