    Abstract:
    OBJECTIVE: The aim of the systematic review is to evaluate the effects of gingivoperiosteoplasty (GPP) on alveolar bone quality and facial growth in patients with cleft lip and palate (CLP). SEARCH METHODS: Electronic and manual search was done up to October 2017. ELIGIBILITY CRITERIA: Clinical and observational studies that compared GPP to control; patients without GPP evaluated either before or after the age for secondary bone graft (SBG). DATA COLLECTION AND ANALYSIS: Studies selection was done by 2 authors independently. Risk ratio and mean difference with 95% confidence intervals (CIs) were calculated using random-effects models. RESULTS: Thirteen articles were included in the review. All studies were at high risk of bias. Poorer alveolar bone quality was found in the GPP group compared to the SBG group. The pooled data showed a statistically significant increase in the incidence of Bergland type III in the GPP group compared to SBG (risk ratio: 11.51, 95% CI: 3.39-35.15). As for facial growth, GPP group resulted in a more retruded maxillary position (as indicated by "Sella-Nasion-Subspinale" angle [SNA value]) compared to control group by -1.36 (CI: -4.21 to 1.49) and -1.66 (CI: -2.48 to -0.84) when evaluated at 5 and 10 years, respectively. The protocol for presurgical infant orthopedics used in conjunction with the GPP procedure might have affected the results of the alveolar bone and facial growth outcomes. CONCLUSIONS: Definitive conclusions about the effectiveness of GPP cannot be drawn. Very weak evidence indicated that GPP might not be an efficient method for alveolar bone reconstruction for patients with unilateral and bilateral CLP. Gingivoperiosteoplasty surgery could lead to maxillary growth inhibition in patients with CLP.
