An abnormal communication between the [[Nasal cavity - Anatomy & Physiology| nasal]] and [[Oral Cavity - Oropharynx - Anatomy & Physiology| oral]] cavities involving the soft and hard palate, premaxilla and or lip. Abnormalities arise from during foetal development where there is incomplete closure of the primary palate, secondary palate or both.  

The primary palate develops into the premaxilla and lip. If closure is not complete this will result in a primary palate or cleft lip(harelip).

The primary palate develops into the premaxilla and lip. If closure is not complete this will result in a primary palate or cleft lip(harelip).

The secondary palate forms the hard and soft palate and incomplete closure of either of these results in a secondary palate or cleft palate.

The secondary palate forms the hard and soft palate and incomplete closure of either of these results in a secondary palate or cleft palate.
