[1] [2] Cleft lip and cleft palate can often be diagnosed during pregnancy with an ultrasound exam. [1] A cleft lip or palate can be successfully treated with surgery. [1] This is often done in the first few months of life for cleft lip and before eighteen months for cleft palate. [1] Speech therapy and dental care may also be needed. [1]
However, when growth of the mandibular process is impeded, a lip pit occurs. Lip pits begin to develop on day 36. Cleft lip begins to develop on day 40, and cleft palate emerges on day 50 of development. [3] There are three types of lip pits, which are classified according to their location: midline upper, comissural, and lower lip.
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Nasomaxillary dysplasia is caused by a development arrest at the junction of the lateral side of the nose and the maxilla, which results in a complete or non-complete cleft between the nose and the orbital floor (nasoocular cleft) or between the mouth, nose and the orbital floor (oronasal-ocular cleft). The development of the lip is normal.
Visual inspection with a penlight shows a healthy palate as whitish in color, with a firm texture and irregular transverse rugae. Abnormal findings include yellowness or extreme pallor, and diseases include torus palatinus, cleft palate, submucous cleft palate, High-arched palate, Kaposi's sarcoma and leukoplakia.
A cleft palate is one of the most common causes of VPI. Cleft palate is an anatomical abnormality that occurs in utero and is present at birth. This malformation can affect the lip and palate, or the palate only. A cleft palate can affect the mobility of the velopharyngeal valve, thereby resulting in VPI. [citation needed]

Veau-III cleft palate: A cleft of the velum (soft palate), extending unilaterally through the secondary hard palate, past the incisive foramen, and through the primary hard palate and alveolus. The vomer (the bony part of the nasal septum) remains attached to the palatal shelf on the greater segment (non-cleft side).
