Overview
Maxillary hypoplasia in CLP deformities results from congenital reduction in midfacial growth and the effects of the surgical scar from CLP repair.Turvey et al. suggested that this disproportionate jaw growth is the biologic consequence of prior surgical intervention for closure of the soft tissues and is not related to the congenital cleft deformity, Midfacial hypoplasia is commonly treated by performing conventional Le Fort surgery to displace the maxilla anteriorly and stabilization afterward with rigid fixation along with orthodontics treatment. . Midface hypoplasia cleft patient has the following characteristics: concave facial profile, inverted nasal tip, wide alar base, acute nasolabial angle, and excessive exposure of sclera. Intraoral findings are anterior and posterior crossbite, CLP, accentuated curve of Spee, Class III dental malocclusion, multiple missing teeth, oronasal communication, and residual cleft. Speech disturbances are also usually present due to velopharyngeal incompetency and oronasal communication.
Interventions
- Procedure orthognathic surgery ,lefort 1,bsso ,DO
Le Fort I osteotomy is often used in the correction of dental occlusion and maxillary hypoplasia in cleft patients. In addition, the osteotomy may also improve patients' facial appearance and self-esteem - Procedure distraction osteogenesis
Distraction osteogenesis is a surgical technique that uses body's own repairing mechanisms for optimal reconstruction of the tissues.
