No nose or lips facial deformities

The characteristics of a unilateral cleft lip nasal deformity may include a spectrum of severity of the following features including 1 an asymmetric nasal tip, 2 caudal septal deflection to the noncleft side, 3 foreshortened columellar skin, 4 alar base malposition anterior, inferior, and posterior , and 5 splaying of the alar base. A typical unilateral cleft lip nasal deformity is shown A. Early B and 2-year postoperative C photographs demonstrate persistent, subtle nasal asymmetry. The spectrum of microform cleft lip and nasal deformities. Shown are features of notched lip mucosa A , elevated cupid's peak B , philtral column furrowing C , notched orbicularis D , and alar base asymmetry with alar hooding E.

As a baby develops during pregnancy, body tissue and special cells from each side of the head grow toward the center of the face and join together to make the face. This joining of tissue forms the facial features, like the lips and mouth. A cleft lip happens if the tissue that makes up the lip does not join completely before birth. This results in an opening in the upper lip.

Frontonasal dysplasia is a condition that results from abnormal development of the head and face before birth. People with frontonasal dysplasia have at least two of the following features: widely spaced eyes ocular hypertelorism ; a broad nose; a slit cleft in one or both sides of the nose; no nasal tip; a central cleft involving the nose, upper lip, or roof of the mouth palate ; incomplete formation of the front of the skull with skin covering the head where bone should be anterior cranium bifidum occultum ; or a widow's peak hairline. Other features of frontonasal dysplasia can include additional facial malformations, absence or malformation of the tissue that connects the left and right halves of the brain the corpus callosum , and intellectual disability. There are at least three types of frontonasal dysplasia that are distinguished by their genetic causes and their signs and symptoms. In addition to the features previously described, each type of frontonasal dysplasia is associated with other distinctive features.

The forehead, orbits, nose, lips and ears can be consistently identified from 12 weeks of gestation. Sagittal, transverse and coronal planes are all useful for the evaluation of normal and abnormal anatomy. A mid-sagittal plane allows visualization of the fetal profile; whereas the ears are visualized in parasagittal scans tangential to the calvarium. The coronal planes are probably the most important ones in the evaluation of the integrity of facial anatomy. Orbits, eyelids, nose, and lips are well visualized.
