This chapter describes the embryological development and congenital anomalies of salivary glands. Development of the major salivary glands consists of three main stages. The first stage is marked by the presence of a primordial anlage and the formation of branched duct buds. The second stage is marked by the early appearance of lobules and duct canalization and the third stage by maturation of acini and ducts. The primordial parotid gland is the first to appear, during the sixth gestational week. In addition to heterotopic glands, congenital anomalies include aplasia, gland duplication and congenitally atretic, imperforate, ectatic, and duplicated ducts.
