Objective: To test the hypothesis that it is possible to perform rapid maxillary expansion (RME) after alveolar bone grafting in patients with clefts of the lip and palate (CLP) without compromising the final result of the bone graft. Design: Occlusal and periapical radiographs of the grafted area of 17 unilateral and 11 bilateral patients with CLP (n  =  28) were obtained before and after RME. Setting and sample population: Hospital for Rehabilitation of Craniofacial Anomalies (HRAC), University of São Paulo. Twenty-eighty patients with CLP who had undergone RME. Interventions: RME was performed in patients with CLP who had already undergone RME before secondary bone grafting but with relapse of the maxillary dental arch constriction, as well as in patients with CLP who had never undergone expansion before bone grafting. Outcome measure: Qualitative evaluation in occlusal and periapical radiographs after alveolar bone grafting. Results: Findings showed opening of the midpalatal suture in 42.8% of patients in this study. Regardless of the success rate of RME, the alveolar bone grafting was not affected when the procedures were inverted. Conclusion: The hypothesis was accepted. RME can be performed after secondary alveolar bone grafting without affecting it.

Objective To demonstrate the feasibility of rapid maxillary expansion (RME) after alveolar bone grafting (ABG) in complete unilateral cleft lip, alveolus and palate (UCLP) without damage to the grafted area. Setting Hospital for Rehabilitation of Craniofacial Anomalies (HRAC), University of São Paulo, Department of Orthodontics. Patient A case report of a 10-year-old boy with a complete UCLP who was treated with RME after secondary ABG procedure. RME was performed 1.3 years after the bone grafting with rhBMP-2 in collagen membrane. Result Postexpansion cone-beam computed tomography (CBCT) axial and coronal sections demonstrated the opening of the midpalatal suture in the premaxilla without damages to the alveolar bone grafting region. Postretention CBCT images showed bone formation at the split midsuture of the premaxilla. Conclusion Rapid maxillary expansion performed after ABG with rH-BMP2 led to complete opening of the premaxillary midline suture without compromising the integrity of the grafted alveolar cleft.

Objective To determine if secondary alveolar bone grafting (SABG) timing in patients with cleft lip and palate (CLP) influences the future need for additional maxillary advancement procedures, particularly Le Fort I osteotomy with rigid external distraction (RED). Design Retrospective cohort study. Groups were separated by SABG timing: early mixed dentition (ages 68 years) or late mixed dentition (ages 9-11 years). The criterion for RED was negative overjet ≥8 mm, and sufficient dental development for RED. Setting Single tertiary care institution. Patients Patients with CLP that underwent SABG from 2010 to 2015. Exclusion criteria included syndromic conditions, SABG surgery at age >12 years, current age <12 years, and <2 years follow-up. 104 patients were included. Main outcome measures The number of RED candidates and treated patients. Results There was no statistical difference in the number of RED candidates ( P  =  .0718) nor treated patients ( P  =  .2716) based on SABG timing; stratification by laterality was also insignificant. Early SABG is associated with higher odds of being a RED candidate (pooled, unilateral, bilateral) and treated patient (pooled and unilateral); however, there were no statistically significant associations between SABG timing and the number of RED candidates and treated patients as determined by logistic regression models. Conclusion There is no statistically significant association between SABG timing and the odds of being a RED candidate or treated patient. Future prospective studies are recommended to assess the relationship between SABG timing and maxillary growth in patients with CLP.
