“…Then further explore the reasons for high heterogeneity in the results, including analyzing study quality and conducting subgroup analysis based on different sample characteristics and treatment methods, such as patient age, gender, degree of palatal suture ossification and staging, palatal bone thickness, length of dental implants, and presence of dental anchorage etc. [ 20 – 24 ]. When the I 2 value was lower than 50%, a fixed effects model was used.…”

Objective This study aims to assess the short- and long-term changes in the upper airway and alar width after mini-implant -assisted rapid palatal expansion (MARPE) in nongrowing patients. Methods Five electronic databases (PubMed, Scopus, Embase, Web of Science, and Cochrane Library) were searched up to 2 August, 2023 based on the PICOS principles. The main outcomes were classified into three groups: 1) nasal cavity changes, 2) upper airway changes and 3) alar changes. The mean difference (MD) and 95% confidence intervals (CI) were used to assess these changes. Heterogeneity tests, subgroup analyses, sensitivity analyses, and publication bias were also analyzed. Result Overall, 22 articles were included for data analysis. Nasal cavity width (WMD: 2.05 mm; 95% CI: 1.10, 3.00) and nasal floor width (WMD: 2.13 mm; 95% CI: 1.16, 3.11) increased significantly. While palatopharyngeal volume (WMD: 0.29 cm3, 95% CI: -0.44, 1.01), glossopharyngeal volume (WMD: 0.30 cm3, 95% CI: -0.29, 0.89) and hypopharyngeal volume (WMD: -0.90 cm3; 95% CI: -1.86, 0.06) remained unchanged, nasal cavity volume (WMD: 1.24 cm3, 95% CI: 0.68, 1.81), nasopharyngeal volume (MD: 0.75 cm3, 95% CI: 0.44, 1.06), oropharyngeal volume (WMD: 0.61 cm3, 95% CI: 0.35, 0.87), and total volume of the upper airway (WMD: 1.67 cm3, 95% CI: 0.68, 2.66) increased significantly. Alar width (WMD: 1.47 mm; 95% CI: 0.40, 2.55) and alar base width (WMD: 1.54 mm; 95% CI: 1.21, 1.87) also increased. Conclusion MARPE can increase nasal cavity width, nasal cavity volume, nasopharyngeal volume and oropharyngeal volume for nongrowing patients, but has no significant effect on hypopharyngeal volume. In addition, the alar width also increased. However, the studies included in this meta-analysis were mainly retrospective, nonrandomized and small in number, so the findings should be interpreted with caution and high-quality RCTs need to be studied.

“…Arqub et al systematically found that increased nasal cavity width after MARPE treatment can reduce respiratory resistance [33]. There was a high level of heterogeneity for width changes, partly due to different activation protocols, with four studies [18, 19,24] activating one turn per day, two studies [25,27] activating one turn every other day, and the remaining four studies activating two turns (0.25 mm per turn) per day. The sensitivity analysis revealed that the ndings were robust and unaffected by the included studies, so the increase in nasal cavity width and nasal oor width after MARPE treatment was signi cant.…”

Objective: This study aims to assess the short- and long-term changes in the upper airway and facial soft tissue after mini-implant -assisted rapid palatal expansion (MARPE) in nongrowing patients with maxillary transverse deficiency (MTD). Methods: Five electronic databases (PubMed, Scopus, Embase, Web of Science, and Cochrane Library) were searched up to 10 March 2023 without limitations and included studies were identified in accordance with the PICOS principles. The main outcomes were classified into three groups: 1) nasal cavity changes, 2) upper airway volume changes and 3) alar changes. Six reviewers independently completed literature screening, data extraction and quality evaluation. The mean difference (MD) and 95% confidence intervals (CI) were used to assess changes in the main outcomes. Heterogeneity tests, subgroup analyses, sensitivity analyses, and publication bias were also analysed. Result: Overall, 2158 articles were retrieved; 18 articles met the inclusion criteria, and 16 articles were included for data analysis. Nasal cavity width (WMD: 1.58 mm; 95% CI: 0.90, 2.26) and nasal floor width (WMD: 1.88 mm; 95% CI: 0.75, 3.02) increased significantly. While palatopharyngeal volume (WMD: 0.2 cm3, 95% CI: -0.61, 1.00), glossopharyngeal volume (WMD: -0.35 cm3, 95% CI: -1.88, 1.18) and hypopharyngeal volume (WMD: -0.90 cm3; 95% CI: -1.86, 0.06) remained unchanged, nasal cavity volume (WMD: 1.24 cm3, 95% CI: 0.68, 1.81), nasopharyngeal volume (MD: 0.75 cm3, 95% CI: 0.44, 1.06), oropharyngeal volume (WMD: 0.59 cm3, 95% CI: 0.27, 0.92), and total volume of the upper airway (WMD: 1.67 cm3, 95% CI: 0.68, 2.66) increased significantly (P<0.05). Alar width (WMD: 1.47 mm; 95% CI: 0.40, 2.55) and alar base width (WMD: 2.02 mm; 95% CI: 0.26, 3.77) also increased in the short term. Conclusion: MARPE can increase nasal cavity width, nasal cavity volume, nasopharyngeal volume and oropharyngeal volume for nongrowing patients, but has no significant effect on hypopharyngeal volume. In addition, the alar width also increased. However, the studies included in this meta-analysis were mainly retrospective, nonrandomized and small in number, so the findings should be interpreted with caution and high-quality RCTs need to be studied.

Background Midpalatal suture (MPS) maturation may be influenced by a range of parameters including age, gender, and vertical skeletal pattern. We therefore aimed to evaluate the effect of Frankfurt-mandibular angle (FMA), skeletal maturation, and age on the timing of MPS maturation. Methods In this cross-sectional study, cone-beam computed tomography (CBCT) and lateral cephalograms were used to assess the MPS and cervical vertebral maturation (CVM) stage. A proportional odds logistic regression model was used to assess associations between age adjusted for gender and MPS maturation, and a regression analysis was performed to analyze the effect of vertical pattern on these associations. Results A total of 201 patients (84 male and 117 female) with a mean age of 13.48 (SD 1.94) were included. With increasing age, the odds of belonging to a higher maturation stage increased (OR: 2.14; 95% CI 1.789; 2.567; P < 0.001); however, no association between FMA and MPS maturation was observed (OR: 1.01; 95% CI 0.964; 1.051; P = 0.76). A strong correlation between MPS maturation and CVM stage was not reported. Males had a higher probability of belonging to a lower MPS maturation stage (OR: 0.24; 95% CI 0.136; 0.415; P < 0.001). Conclusions Based on this cross-sectional analysis, midpalatal sutural maturation classification is associated with chronological age and occurs later in males. Neither CVM staging nor variation in vertical skeletal proportions were useful predictors of midpalatal maturation stage.
