The association of auricular abnormalities and cleft lip with or without cleft palate has been described in two siblings.

The second sibling was a fetus (gestational age: 23 weeks) with severe cleft lip, cleft palate and external ear abnormalities.

The presence of a cleft in the oral cavity, the two main types of which are cleft lip and cleft palate. In cleft lip, there is the congenital failure of the maxillary and median nasal processes to fuse, forming a groove or fissure in the lip. In cleft palate, there is a congenital failure of the palate to fuse properly, forming a grooved depression or fissure in the roof of the mouth. Clefts of the lip and palate can occur individually or together. It is preferable to code each defect separately.
