Gingivoperiosteoplasty in Children with Cleft Lip and Palate: The Need for Alveolar Bone Grafting

Abstract

Objective This study aimed to determine the efficacy of gingivoperiosteoplasty (GPP) in preventing alveolar bone grafting (ABG) among children with cleft lip and palate (CLP). Design/Setting Retrospective university hospital single center study. Patients Children with CLP treated with GPP from 2000-2015 were included. Those under eight years of age, without definitive conclusions regarding need for ABG or with incomplete data were excluded. Interventions Included patients were analyzed for demographics, cleft type, age at GPP, associated cleft surgery, use of nasoalveolar molding (NAM), indication for ABG, operating surgeon and presence of residual alveolar fistula. T-tests and Fisher's exact tests were utilized for statistical analysis. Main Outcome Measure The need for ABG. Results Of the 1682 children identified with CLP, 64 underwent GPP and met inclusion criteria. 78% of patients with CLP who underwent GPP were recommended for ABG. Those who received GPP at a younger age ( P = .004) and at the time of initial cleft lip repair ( P = .022) were less likely to be recommended for ABG. Patients with complete CLP were more likely to be recommended for ABG than patients with cleft lip and alveolus only ( P = .015). The operating surgeon impacted the likelihood of ABG ( P = .004). Patient gender, race, ethnicity, laterality, and NAM were not significantly associated with recommendation for ABG. Conclusion GPP does not preclude the need for ABG. Therefore, the success of ABG after GPP and maxillary growth restriction should be analyzed further to determine if GPP is a worthwhile adjunct to ABG in cleft care.
