METHODS: Genome-wide linkage analysis was carried out on eight large extended families of NSCL/P with the total of 91 individuals among Malay population using microarray platform. Based on linkage analyses findings, copy number variation (CNV) of LPHN2, SATB2, PVRL3, COL21A1, and TOX3 were identified in four large extended families that showed linkage evidence using quantitative polymerase chain reaction (qPCR) as for a validation purpose. Copy number calculated (CNC) for each genes were determined with Applied Biosystems CopyCallerTM Software v2.0. Normal CNC of the target sequence expected was set at two.
RESULTS: Genome-wide linkage analysis had discovered several genes including TOX3 and COL21A1 in four different loci 4p15.2-p16.1, 6p11.2-p12.3, 14q13-q21, and 16q12.1. There was significant decreased, p
DESIGN: Retrospective observational study.
SETTING: Two regional cleft-referral centers.
MAIN OUTCOME MEASURES: In the current study, 101 pairs of dental models of non-syndromic CUCLP patients were retrieved from hospital archives. Each occlusal relationship from central incisor till the first permanent molars were scored except the lateral incisor. Sum of 10 occlusal relationships in each study sample gave a total occlusion score. The primary outcome was the mean total occlusion score.
RESULTS: According to MHB, a mean (standard deviation) total occlusion score of -8.92 (6.89) was determined. Based on treatment outcome, 66 cases were favorable (grades 1, 2, and 3) and 35 cases were unfavorable (grades 4 and 5). Chi-square tests indicated, difference of cheiloplasty ( P = .001) and palatoplasty ( P < .001) statistically significant. Five variables-gender, family history of cleft, cleft side, cheiloplasty, and palatoplasty-were analyzed with a logistic regression model.
CONCLUSIONS: Final model indicated that cases treated with modified Millard technique (cheiloplasty) and Veau-Wardill-Kilner method (palatoplasty) had higher odds of unfavorable treatment outcome.
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.
