Maxillary sinus septa increase perforation risk of Schneiderian membrane during the sinus floor elevation (SFE). Cone Beam Computed Tomography (CBCT) allows for a more precise assessment of the septal position; thus, preoperative CBCT analysis is substantial to avoid possible complications. This study aims to investigate the 3D characteristics of the maxillary sinus septa based on CBCT images. To our knowledge, no study reported the CBCT-based investigation for the sinus septa among Yemeni population.
This is a retrospective cross-sectional analysis of 880 sinus CBCT images 440 patients. The septa prevalence, locations, orientations, morphology, and associated factors were analyzed. The effect of age, gender, and dental status on the sinus septa and the relationship between sinus membrane pathology and sinus septa were also analyzed. Anatomage (Invivo version 6) was used for CBCT images analysis. Descriptive and analytical statistics were performed, and a P-value < 0.05 was significantly considered.
The maxillary sinus septa were found among 63.9% of patients and 47% of sinuses. The average septa height was 5.2 mm. 15.7% of patients had septa in the right maxilla, 18% in the left, and 30.2% in both. Gender, age, and dental condition had no influence on the presence of septa, and septa presence did not influence sinus membrane pathology. Many septa originated from the floor (54.5%), located in the middle (43%), with coronal orientation (66%) and complete configuration (58.2%).
Based on our findings, the septa prevalence, locations, orientations, and morphology were significant and equivalent to the highest recorded in the literature yet. Thus, when sinus floor elevation is planned, CBCT imaging of the maxillary sinus is recommended for safe dental implantation.
在上颌窦提升（SFE）过程中，上颌窦间隔会增加施氏膜穿孔的风险。锥形束 CT（CBCT）允许更精确地评估间隔位置；因此，术前 CBCT 分析对于避免可能的并发症至关重要。本研究旨在基于 CBCT 图像研究上颌窦间隔的 3D 特征。据我们所知，在也门人群中，还没有关于基于 CBCT 的窦间隔研究的报道。
这是一项对 440 例患者的 880 例鼻窦 CBCT 图像的回顾性横断面分析。分析了间隔的发生率、位置、方向、形态以及相关因素。还分析了年龄、性别和牙齿状况对上颌窦间隔的影响，以及窦膜病变与窦间隔之间的关系。使用解剖学（Invivo 版本 6）进行 CBCT 图像分析。进行描述性和分析性统计分析，P 值<0.05 被认为具有统计学意义。
在 63.9%的患者和 47%的窦中发现了上颌窦间隔。间隔的平均高度为 5.2 毫米。15.7%的患者右侧上颌窦有间隔，18%左侧，30.2%两侧均有。性别、年龄和牙齿状况对上颌窦间隔的存在没有影响，而间隔的存在也不会影响窦膜的病理。许多间隔起源于窦底（54.5%），位于窦腔中部（43%），冠状方向（66%），完全形态（58.2%）。
根据我们的发现，间隔的发生率、位置、方向和形态与文献中记录的最高值显著相当。因此，在上颌窦底提升术计划中，推荐对上颌窦进行 CBCT 成像，以确保安全的牙科植入。
