Abstract

Abstract : Abstract: Maxillary sinusitis is 1 of the postoperative complications of the Le Fort I osteotomy, this study investigated the related factors of maxillary sinusitis after Le Fort I osteotomy. A total of 23 cases, 92 controls, and 11 related factors were included in this case-control study with a 1:4 case-control ratio. The risk factors for maxillary sinusitis after Le Fort I were examined by least absolute shrinkage and selection operator multivariate conditional logistic regression and least absolute shrinkage and selection operator multivariate linear regression. The patency of maxillary sinus ostium at 6 months after surgery was significantly associated with maxillary sinusitis after Le Fort I osteotomy. Compared with the obstructed maxillary sinus ostium, the percentage of the volume of the healthy air cavity in the complete sinus cavity increased 70.7% when the maxillary sinus ostium was unobstructed, and 95% confidence interval was 0.610 to 0.805. Similarly, when the maxillary sinus ostium was wide, the percentage increased 6.0% compared with the narrow 1, and 95% confidence interval was 0.013 to 0.107. This study indicated that the patency of maxillary sinus ostium has an important impact on maxillary sinusitis after Le Fort I osteotomy. Close attention should be paid to maintain the maxillary sinus ostium and the drainage of maxillary sinuses unobstructed in a clinical setting.
