==Description==
An abnormal communication between the [[Nasal cavity - Anatomy & Physiology| nasal]] and [[Oral Cavity - Oropharynx - Anatomy & Physiology| oral]] cavities involving the [[Soft Palate - Anatomy & Physiology| soft palate]] , [[Hard Palate - Anatomy & Physiology| hard palate]], premaxilla and or [[Lips - Anatomy & Physiology|lip]] . Abnormalities arise 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.
