Abstract: Objective The aim of this study was to analyze the imaging data and investigate the influence of the differences and correlations of local anatomical structures on the occurrence of major complications of lateral window technique for sinus floor elevation, in order to provide help for avoiding the occurrence of complications. Methods The maxillary sinus images of 380 patients (206 males and 174 females) were analyzed by cone-beam CT scanning to measure the width of the maxillary sinus, the angle formed by the lateral and the medial walls of the maxillary sinus at the floor of the maxillary sinus (LFM), the thickness of the lateral wall of the maxillary sinus, the thickness of the mucoperiosteum at the floor of the maxillary sinus, the diameter of the blood vessels of the lateral wall of the maxillary sinus, the height of the remaining alveolar bone, and to analyze correlations between the local anatomical factors that contributed to the development of the complications of lateral window technique for sinus floor elevation. Results Maxillary sinus width was positively correlated with LFM, and the correlation was statistically significant at all tooth sites(P<0.05). There was a positive correlation between remaining alveolar bone height and maxillary sinus lateral wall thickness, vessel diameter and lateral wall thickness, and vessel diameter and remaining alveolar bone height, and the correlation was statistically significant in some of the tooth sites (P<0.05). Conclusions The study and statistical analysis from the imaging point of view revealed that among the factors that may cause complications of lateral window technique for sinus floor elevation, the maxillary sinus width has a positive correlation with the LFM, the remaining alveolar bone height with the maxillary sinus lateral wall thickness, the blood vessel diameter with the maxillary sinus lateral wall thickness, and the blood vessel diameter with the remaining alveolar bone height.
