【摘要】：目的研究在种植上颌窦提升过程中,造成手术出血的上颌窦骨内血管在中国人群中的分布情况,分析血管的存在对手术的影响。方法纳入年龄35岁以上,拍摄CBCT包含双侧清晰上颌窦影像的患者进行分析。共纳入患者150例(300侧上颌窦)。观察相应区域的骨内血管是否存在,测量血管离窦底的垂直距离,以及血管的直径。研究由2名实验员独立进行观察和测量,并分析数据。结果共发现有122侧上颌窦区域有骨性血管存在,占患者总数的40.6%。血管距离窦底的平均距离为(7.19±1.36)mm,而血管的平均直径为(1.32±0.51)mm。在发现率上,男性较女性高,血管的高度上男性高于女性,血管直径上男性粗于女性,差异均无统计学意义。双侧血管的存在和形态上具有一定对称性。结论上颌窦区域骨内血管的粗大和较低的垂直高度可能会造成种植外提升手术中的出血,术前应拍摄CBCT确定在手术区域有无粗大血管影响,但阴性的结果并不能排除损伤血管的可能性。手术时应该控制开窗范围避免并发症的产生。
[Abstract]:Objective to study the distribution of intraosseous vessels of maxillary sinus caused by surgical bleeding in Chinese population during the implantation of maxillary sinus, and to analyze the influence of the presence of blood vessels on the operation. Methods patients over 35 years old who were photographed with bilateral clear maxillary sinus images on CBCT were analyzed. A total of 150 patients with 300 sides of maxillary sinus were included. The presence of intraosseous vessels, the vertical distance from the sinus floor and the diameter of the blood vessels were observed. The study was observed and measured independently by two experimenters, and the data were analyzed. Results there were 122 osseous vessels in the maxillary sinus area, accounting for 40.6% of the total number of patients. The average distance from the bottom of the sinus was 7.19 卤1.36 mm, and the average diameter of the blood vessel was 1.32 卤0.51mm. The detection rate was higher in male than in female, the height of blood vessel in male was higher than that in female, and the diameter of vessel in male was thicker than that in female, the difference was not statistically significant. The existence and morphology of bilateral blood vessels have certain symmetry. Conclusion the large and low vertical height of the intraosseous vessels in the maxillary sinus region may result in hemorrhage in the extracellular lifting operation. Before operation, CBCT should be taken to determine if there is any influence of the large blood vessels in the area of operation. But negative results do not rule out the possibility of blood vessel damage. The scope of window opening should be controlled during surgery to avoid complications.
