摘　　要：目的通过对锥形束CT(cone beam computed tomography,CBCT)图像的测量分析,研究上颌窦外侧壁骨内血管的形态与位置。方法选取2020年12月至2021年12月福建医科大学附属协和医院收治的需进行口腔放射检查的102例患者为研究对象。通过3D Viewer软件对其CBCT图像进行观察测量,分析上颌窦外侧壁骨内血管的检出率、位置、走行、直径、终端位置及终端与上颌牙槽嵴顶的距离。结果102例患者的双侧上颌窦外侧壁骨内血管的检出率为94.6%(193/204);其位置均为鼻上,走行为唇向者占79.3%,腭向者占20.7%。不同性别、侧别的上颌窦外侧壁骨内血管方向、终端位置比较差异均无统计学意义(P>0.05)。上颌窦外侧壁骨内血管的直径在终端处显著大于分叉处[(1.20±0.29)mm vs.(0.75±0.21)mm,t=18.688,P<0.001]。男性上颌窦外侧壁骨内血管与上颌牙槽嵴顶间距离显著大于女性[(20.62±3.69)mm vs.(17.83±2.95)mm,t=5.900,P<0.001]。结论CBCT图像对上颌窦外侧壁骨内血管的检出率高。上颌窦外侧壁骨内血管的终端位置多样,其与上颌骨及鼻腔等重要解剖结构关系紧密,术前进行CBCT图像分析对优化手术路径并减少出血等并发症具有重要意义。Objective To based on cone beam computed tomography(CBCT)image analysis,the morphology and location of vessel in the lateral sinus wall of maxillary sinus were studied.Methods A total of 102 patients requiring oral radiological examination admitted to Fujian Medical University Union Hospital from December 2020 to December 2021 were selected as the study objects.The CBCT images were observed and measured by 3D Viewer software,and the detection rate,location,path,diameter,terminal position and distance between terminal and crest of alveolar ridge of vessel in the lateral sinus wall of maxillary sinus were analyzed.Results In 102 patients with bilateral maxillary sinus,the detection rate of vessel in the lateral sinus wall of maxillary sinus was 94.6%(193/204).All of them were located above the region of nasal cavity,79.3%were labial-oriented and 20.7%were palatal-oriented.There were no significant differences in the direction and terminal position of vessel in the lateral sinus wall of maxillary sinus between different genders and sides(P>0.05).The diameter of vessel in the lateral sinus wall of maxillary sinus was significantly larger at the terminal than at the fork[(1.20±0.29)mm vs.(0.75±0.21)mm,t=18.688,P<0.001].The distance between vessel in the lateral sinus wall of maxillary sinus and the crest of dental alveolus of maxilla was significantly greater in male than in female[(20.62±3.69)mm vs.(17.83±2.95)mm,t=5.900,P<0.001].Conclusion CBCT images showed a high detection rate of vessel in the lateral sinus wall of maxillary sinus.There are various terminal positions of vessel in the lateral sinus wall of maxillary sinus,which are closely related to important anatomical structures such as the maxilla and nasal cavity.Preoperative CBCT image analysis has great significance to optimize the surgical path and reduce complications such as bleeding.
