The surgery-first approach (SFA) in orthognathic surgery, performed without presurgical orthodontic treatment, has gained attention, but the results remain controversial. The purpose of this study was to assess the current evidence on stability, efficacy, and surgical results of SFA versus conventional 3-stage method (CTM) orthognathic surgery.A comprehensive search in PubMed and Web of Science was conducted. A systematic review and cumulative meta-analysis of all comparative studies were performed to assess the 2 strategies (SFA and CTM) using a random- or a fixed-effects model. Outcomes included treatment duration, postoperative stability, surgical movement, and postoperative occlusion.Ten nonrandomized controlled studies including 513 patients were identified. Compared with CTM, patients in the SFA group benefited from shorter total treatment duration (weighted mean difference [WMD], -5.25; 95% confidence interval [CI], -8.21 to -2.29; P = .0005), similar postoperative stability of the mandible (WMD, 0.35 mm; 95% CI, -0.24 to 0.94; P = .55) and maxilla (WMD, 0.13 mm; 95% CI, -0.35 to 0.60; P = .60), similar surgical movements, and other surgical results.SFA offers an efficient alternative to CTM with shorter total treatment duration, similar postoperative stability, and other surgical results but longer postoperative orthodontic time.

The primary restriction on high resolution remote sensing data is the limit observation frequency. Using a network of multiple sensors is an efficient approach to increase the observations in a specific period. This study explores a leaf area index (LAI) inversion method based on a 30 m multi-sensor dataset generated from HJ1/CCD and Landsat8/OLI, from June to August 2013 in the middle reach of the Heihe River Basin, China. The characteristics of the multi-sensor dataset, including the percentage of valid observations, the distribution of observation angles and the variation between different sensor observations, were analyzed. To reduce the possible discrepancy between different satellite sensors on LAI inversion, a quality control system for the observations was designed. LAI is retrieved from the high quality of single-sensor observations based on a look-up table constructed by a unified model. The averaged LAI inversion over a 10-day period is set as the synthetic LAI value. The percentage of valid LAI inversions increases significantly from 6.4% to 49.7% for single-sensors to 75.9% for multi-sensors. LAI retrieved from the multi-sensor dataset show good agreement with the field measurements. The correlation coefficient (R2) is 0.90, and the average root mean square error (RMSE) is 0.42. The network of multiple sensors with 30 m spatial resolution can generate LAI products with reasonable accuracy and meaningful temporal resolution.
