Abstract

Occurrences of dental and skeletal deformities are much more common in those who have cleft lip, cleft palate or both, than in the general population. The primary lip and palate repair carried out during infancy and early childhood provides the foundation for normal speech, occlusion and facial appearance. One long term negative effect of cleft palate surgery is a significant retardation of maxillary growth resulting in secondary deformities of the jaws and malocclusion. These deformities are variable, and are related to various factors. These include the severity of the original defect, the surgical procedures performed, the development of complications and the subsequent orthodontic treatment. Extensive operative intervention in the maxilla and cartilaginous nasal skeleton in early childhood increases the probability of malformation of the midface. There is no intrinsic growth deficiency in patients with clefts, and among the myriad of factors that combine to yield poor maxillary growth, the most influential is surgery. Secondary defects often include lip deformity, alveolar cleft, oro-nasal fistula, mid-facial hypoplasia, dental defects (like crowding, collapsed arch), palatal scar, velopharyngeal incompetence, and septal and other deformities of the nose. The physiological functions affected are speech, respiration, hearing, mastication, deglutition, etc.
