The variability in the maxillary sinus anatomy makes dental implant planning challenging. One of the anatomical landmarks that could affect the decision for implant placement around the maxillary sinus is the sinus septa. This study aimed to retrospectively determine the prevalence, anatomical distribution, and morphology of the maxillary sinus septa.
This study included 309 CBCT images that were analyzed to determine the prevalence, height, location, and orientation of the maxillary sinus septa. Descriptive statistics, Mann‒Whitney U tests, and Kruskal‒Wallis tests were used for data analysis.
A total of 618 maxillary sinuses were analyzed. Maxillary septa were present in 30% (n = 188) of the sinuses and in approximately 45% of the analyzed images. The mean height of the septa was 5.09 mm. The presence of bilateral septa was evident in 49 subjects (35.25%). Female subjects were significantly more likely to have only one septum (n = 67, 53.6%, p < 0.05).
The presence of septa is very common, found in one-third to approximately half of the evaluated cases, which warrants careful examination before any surgical interventions to avoid possible complications.
上颌窦解剖结构的变异性使得牙种植体规划具有挑战性。可能影响上颌窦周围种植体放置决策的解剖学标志之一是窦隔。本研究旨在回顾性确定上颌窦隔的发生率、解剖分布和形态。
本研究纳入了 309 例 CBCT 图像，用于分析上颌窦隔的发生率、高度、位置和方向。采用描述性统计、Mann-Whitney U 检验和 Kruskal-Wallis 检验进行数据分析。
共分析了 618 个上颌窦。上颌窦隔存在于 30%（n=188）的窦中，约占分析图像的 45%。隔的平均高度为 5.09mm。49 名受试者（35.25%）存在双侧隔。女性受试者更可能只有一个隔（n=67，53.6%，p<0.05）。
隔的存在非常常见，在评估病例的三分之一到一半左右可见，这需要在任何手术干预之前进行仔细检查，以避免可能的并发症。
