Anatomic variation can potentially impact the surgical safety.
The purpose of this cross-sectional study was to assess the prevalence of ostiomeatal complex variations based on cone beam computed tomography (CBCT) images of the patients seeking rhinoplasty.
In this cross-sectional study, CBCT images of 281 patients including 153 female and 128 male with Mean±SD age of 26.97±7.38 were retrieved and analyzed for presence of variations of ostiomeatal complex and mucosal thickening. All CBCT images were acquired by NewTom VGi scanner with 15×15 field of view, as a part of preoperative recording of patients seeking rhinoplasty in an otolaryngology clinic. Chi- square test and Odds ratio were used for statistical analysis of the obtained data and p< 0.05 was considered to be statistically significant.
Agger nasi cells which were seen in 93.2% of the cases were the most common anatomic variation. It was followed by Haller cells (68%), concha bullosa (67.3%), uncinate process variations (54.8%), nasal sepal deviation (49.5%) and paradoxical curvature of middle turbinate (10%). Mucosal thickening were detected in 60.7% of the studied cases.
Ostiomeatal complex variations and mucosal thickening are considerably prevalent among the patients seeking rhinoplasty. This study also revealed that CBCT evaluation of paranasal sinuses has comparable result in delineation of the sinonasal anatomy.
解剖变异可能会影响手术安全性。
本横断面研究的目的是基于接受隆鼻手术患者的锥形束计算机断层扫描（CBCT）图像评估窦口鼻道复合体变异的患病率。
在这项横断面研究中，检索并分析了281例患者的CBCT图像，其中包括153名女性和128名男性，平均年龄±标准差为26.97±7.38岁，以确定是否存在窦口鼻道复合体变异和黏膜增厚。所有CBCT图像均由视野为15×15的NewTom VGi扫描仪采集，作为一家耳鼻喉科诊所接受隆鼻手术患者术前记录的一部分。采用卡方检验和比值比对所得数据进行统计分析，p<0.05被认为具有统计学意义。
在93.2%的病例中可见鼻丘气房，是最常见的解剖变异。其次是Haller气房（68%）、泡状鼻甲（67.3%）、钩突变异（54.8%）、鼻中隔偏曲（49.5%）和中鼻甲反常弯曲（10%）。在60.7%的研究病例中检测到黏膜增厚。
窦口鼻道复合体变异和黏膜增厚在接受隆鼻手术的患者中相当普遍。本研究还表明，CBCT对鼻窦的评估在描绘鼻窦解剖结构方面具有可比的结果。
