Presurgical Maxillary Orthopedics and Primary Alveolar Closure: Protocol and Long-term Effects on Midfacial Growth in Patients With Complete Unilateral and Bilateral Clefts

摘要

BACKGROUND: In a complete cleft lip and palate, a defect exists in the alveolar segment of the maxilla. In order to achieve successful restoration of the maxillary arch, several techniques have been employed with the ultimate goal of achieving continuity and adequate bone stock across the alveolus. Passive orthodontic appliances (POA) and gingivoperiosteoplasty (GPP) are adjuncts utilized by some surgeons with primary cleft lip repair. POA aligns the alveolar segments prior to cleft lip repair, and GPP is utilized to achieve bony union across the cleft at the time of primary lip repair. The use of these treatments remains controversial. Along with the surgical technique of the cleft lip and palate repair, they have the possibility of impacting midface growth. Here, we present our protocol for cleft lip and palate repair utilizing GPP and POA for complete unilateral and bilateral cleft lip and palate patients. We also report preliminary treatment results in complete unilateral and bilateral cleft patients, evaluating midface growth at mixed dentition.
