据报道，拔牙和牙根向上颌窦的投射可以大大降低从牙槽脊到上颌窦底的骨高度，而牙齿缺失会导致上颌窦扩张，这些都是上颌磨牙区种植体治疗的重要考虑因素。因此，在隆鼻术前，评估上颌窦作为复杂因素的解剖学特征是至关重要的。我们对牙齿缺失和鼻中隔偏曲(NSD)对上颌窦体积(MSV)的影响进行了三维检查。我们从2019年4月至2020年12月期间接受上颌窦隆起术的患者中选择了有两颗或两颗以上牙齿缺失的参与者进行单侧自由端鞍座手术。用锥束计算机断层扫描(CBCT)计算MSV和NSD。我们使用Wilcoxon t检验比较了每个患者双侧有无牙齿和NSD与MSV的关系。P值 <； 表示有统计学意义。这项研究包括30名患者(30名鼻窦；12名男性，18名女性)。患者平均年龄58.2 ± 10.2岁(男性60.4 ± 3.7岁；女性59.2 ± 4.5岁；范围40~77岁)。平均缺牙数2.98 ± 1.01：缺牙2颗13颗，缺牙3颗及以上17颗。NSD患者9例(30%)。NSD患侧和对侧的平均MSV分别为21.50 ± 3.84 cm~3和22.10 ± 3.56 cm~3，NSD对MSV无明显影响(p = 0.150)。无牙侧平均MSV值为21.58 ± 3.89 cm~3，无牙侧平均MSV值为21.77 ± 4.30 cm~3，无牙侧MSV值明显小于无牙侧(p = 0.00036)。尽管这项研究是一项有限的术前研究，但对部分无牙颌患者的上颌窦进行CBCT三维测量显示，牙齿缺失会导致MSV显著降低，而NSD与MSV无关。
Tooth extraction and the projection of the tooth roots into the maxillary sinus are reported to greatly reduce the bone height from the alveolar ridge to the maxillary sinus floor, while missing teeth are reported to lead to the expansion of the maxillary sinus, all of which are important considerations during dental implant treatment for the maxillary molar region. Therefore, assessing the anatomical characteristics of the maxillary sinus acting as complicating factors is crucial before sinus augmentation. We conducted a three-dimensional examination of the effects of missing teeth and nasal septal deviation (NSD) on maxillary sinus volume (MSV). We selected participants with two or more missing teeth from patients who underwent maxillary sinus augmentation for a unilateral free-end saddle between April 2019 and December 2020. We calculated the MSV and NSD using cone-beam computed tomography (CBCT). We compared the relationships of the presence/absence of teeth and NSD with MSV bilaterally in each patient using the Wilcoxon t-test. p-values < 0.05 denoted statistical significance. This study included 30 patients (30 sinuses; 12 men, 18 women). The average patient age was 58.2 ± 10.2 years (men, 60.4 ± 3.7 years; women, 59.2 ± 4.5 years; range, 40–77 years). The mean number of missing teeth was 2.98 ± 1.01: 13 patients had two missing teeth and 17 had three or more missing teeth. Nine patients (30%) had NSD. The mean MSV on the ipsilateral and contralateral sides of the NSD was 21.50 ± 3.84 cm3 and 22.10 ± 3.56 cm3, respectively; thus, NSD did not affect MSV (p = 0.150). The mean MSV on the edentulous and non-edentulous sides was 21.58 ± 3.89 cm3 and 21.77 ± 4.30 cm3, respectively; thus, the MSV was significantly smaller on the edentulous side (p = 0.00036). Although this study was a limited preoperative study, three-dimensional measurement of the maxillary sinus with CBCT in partially edentulous patients revealed that missing teeth lead to substantial reductions in MSV, while NSD was not associated with MSV.
