Abstract
Cleft lip and palate (CLP) is one of the most common facial deformities. Treatment is long and complex, requiring a multidisciplinary team, including an orthodontist, who plays a prime role in ensuring that dental phenomena occur under the best possible conditions allowed by often unfavorable anatomy and growth and healing factors. Orthodontic preparation by maxillary expansion is a key step in management, mandatory ahead of gingivoperiosteoplasty and alveolar bone graft. Since 2000, Pr Vasquez’s maxillofacial and plastic surgery team in the Necker Hospital (Paris, France) has used a treatment protocol involving alveolar cleft repair by gingivoperiosteoplasty and alveolar bone graft at 4-6 years of age.Orthopedic mechanics induces not only strictly orthopedic effects but also orthodontic dento-alveolar compensation. In CLP, physiology is exceptional in that there is no median palatine suture between fragments, and it can be supposed that the behavior of surrounding structures during maxillary expansion differs from that is a classical patient.We therefore undertook a radiologic study of the dento-alveolar phenomena accompanying preoperative orthodontic expansion in bilateral CLP patients, in a group selected from those jointly managed by Pr Vazquez’s team and Dr Vi Fane’s team in the Rothschild Hospital (Paris), under the auspices of the MAFACE rare diseases reference center.
Highlights
Cleft lip and palate (CLP) is a very heterogeneous clinical entity comprising congenital deformities of mixed genetic and environmental origin
CLP is associated with major deformity of the central face, with marked tissue discontinuity and labio-columellar defect[16]
7 patients with complete bilateral CLP were included in this retrospective study: 3 boys, 4 girls; mean age at start of orthopedic treatment, 4.5 years
Summary
Cleft lip and palate (CLP) is a very heterogeneous clinical entity comprising congenital deformities of mixed genetic and environmental origin. It affects the orofacial region, with involvement of varying complexity of the lip, nose, alveolar region and hard and soft palate and is due to fusion defect in the embryonic buds occurring at 4-12 weeks’ gestation. Muscular discontinuity entails dynamic imbalance; all the cartilage structures to which the affected muscles insert gradually deform, being very malleable. CLP shows 2:1 male predominance[1]
