Maxillary sinus pathologic conditions increase the risk of complications during sinus augmentation surgeries in the posterior maxilla. The present study aimed to determine the frequencies of maxillary sinus pathologic findings on patients' cone-beam computed tomography (CBCT) images to receive dental implants.
In this descriptive/cross-sectional study, 140 CBCT images of patients who were candidates to receive dental implants were evaluated for the presence of maxillary sinus pathologic entities during 6 months, were divided into five categories: mucosal thickening of >5 mm, retention cyst, partial or complete opacification of the sinus, polypoidal mucosal thickening, and healthy patients. Age, gender, and dental status were evaluated in terms of relationship with the sinus pathologic findings. Absolute and relative frequencies were used to describe data. The chi-squared test was used to analyze the variables. Statistical significance was set at <0.05.
The frequency of maxillary sinus pathologic entities on CBCT images was 63.5%. The pathologic conditions in descending frequency were as follows: mucosal thickening (31.4%), retention cyst (17.1%), partial or complete opacification of the sinus (9.3%), and polypoidal mucosal thickening (5.7%). The frequency of pathologic findings in the maxillary sinus was higher in the <46-year age group and subjects with partial edentulism; however, the differences were not significant.
In the present study, the most frequent maxillary sinus pathologic entity was mucosal thickening. There was no relationship between age, sex, and dentition status and maxillary sinus pathologic findings.
上颌窦病理状况会增加上颌后部窦底提升手术期间发生并发症的风险。本研究旨在确定接受牙种植患者锥形束计算机断层扫描（CBCT）图像上上颌窦病理表现的频率。
在这项描述性/横断面研究中，对140例拟接受牙种植患者的CBCT图像进行了6个月的评估，以确定上颌窦病理实体的存在情况，分为五类：黏膜增厚>5mm、潴留囊肿、窦腔部分或完全浑浊、息肉样黏膜增厚以及健康患者。从与窦病理表现的关系方面评估年龄、性别和牙齿状况。采用绝对频率和相对频率描述数据。使用卡方检验分析变量。设定统计学显著性为<0.05。
CBCT图像上上颌窦病理实体的频率为63.5%。病理状况按频率从高到低依次为：黏膜增厚（31.4%）、潴留囊肿（17.1%）、窦腔部分或完全浑浊（9.3%）、息肉样黏膜增厚（5.7%）。上颌窦病理表现的频率在<46岁年龄组和部分牙列缺失患者中较高；然而，差异不显著。
在本研究中，最常见的上颌窦病理实体是黏膜增厚。年龄、性别和牙列状况与上颌窦病理表现之间无关联。
