Experts suggest that parents discuss with their children ways to handle negative social situations related to their cleft lip or cleft palate.
A child who is entering school should learn the proper (and age-appropriate) terms related to the cleft.
It occurs due to the failure of fusion of the lateral palatine processes, the nasal septum, or the median palatine processes (formation of the secondary palate). Because of the gap, air leaks into the nasal cavity resulting in a hypernasal voice resonance and nasal emissions while talking.
The hole in the roof of the mouth caused by a cleft connects the mouth directly to the inside of the nose. Secondary effects of VPI include speech articulation errors (e.g., distortions, substitutions, and omissions) and compensatory misarticulations and mispronunciations (e.g., glottal stops and posterior nasal fricatives).
Lip cleft can occur as a one-sided (unilateral) or two-sided (bilateral) condition.
