There are several vascular vessels that supply the maxillary sinus, such as the posterior superior alveolar artery, the anterior superior alveolar artery, and the infraorbital artery (IOA). These vessels have to be taken into consideration during a sinus augmentation because of the potential risk of bleeding during the procedure. The objective of this investigation was to study variations in maxillary sinus artery connections with the potential surgical effect during a sinus floor elevation by the lateral wall.
The first part of the study was done in 32 anatomical specimens embedded in 10% formaldehyde solution and aged between 55 and 70 years (mean, 61.3 years). The second part of the study was a radiographic study using computerized tomographic (CT) scan images in 35 randomized patients treated in odontology and maxillofacial surgery departments.
Results were recorded for 134 sinuses. In most cases, there was no vessel visible or no vessel present with a diameter less than 0.5 mm after dissection or CT-scan analysis: 120 sinuses (89.5%). In 14 cases (10.5%) there were vessels in the lower two thirds of the anterolateral wall. In 10 sinuses (71.4% of the 14 cases), there was an intraosseous or intrawall artery and in 2 sinuses (14.3%) they were in the intrasinusal position. In 8 of the 14 sinuses (57.1%, about 6% of overall sinuses) the diameter was between 1 and 2.5 mm.
Knowledge of the arterial supply is essential for surgical treatment in the sinus area. A CT scan is recommended and the radiologist must be advised to search for intraosseous or extraosseous vessels in the lower two thirds of the maxillary sinus.
有几条血管为上颌窦供血，如后上牙槽动脉、前上牙槽动脉和眶下动脉（IOA）。由于在手术过程中存在出血的潜在风险，在进行上颌窦提升术时必须考虑这些血管。本研究的目的是研究上颌窦动脉连接的变异情况及其在侧壁上颌窦底提升术中的潜在手术影响。
研究的第一部分在32个浸泡于10%甲醛溶液中的解剖标本上进行，标本年龄在55至70岁之间（平均61.3岁）。研究的第二部分是一项影像学研究，使用计算机断层扫描（CT）图像，对35名在牙科和颌面外科接受治疗的随机患者进行分析。
记录了134个鼻窦的结果。在大多数情况下，解剖或CT扫描分析后未见血管或直径小于0.5毫米的血管：120个鼻窦（89.5%）。在14个病例（10.5%）中，在前外侧壁的下三分之二处有血管。在10个鼻窦（占14个病例的71.4%）中，有骨内或壁内动脉，在2个鼻窦（14.3%）中，它们位于窦内位置。在14个鼻窦中的8个（57.1%，约占所有鼻窦的6%）中，血管直径在1至2.5毫米之间。
了解动脉供应情况对于鼻窦区域的手术治疗至关重要。建议进行CT扫描，并必须告知放射科医生在上颌窦下三分之二处寻找骨内或骨外血管。
