目的:利用锥形束CT(cone-beam computed tomography,CBCT)对下颌骨舌侧孔(mandibular lingual foramina,MLF)进行影像学评估。方法:从四川大学华西口腔医院影像数据库中随机选取567例患者的CBCT影像资料,观察下颌骨舌侧孔的数量,对应的位置以及发生频率。结果:567例患者CBCT图像观察到MLF 1203个。555例患者在下颌骨中线处发现MLF,占样本总人数的97.88%。217例(38.27%)和59例(10.41%)患者分别在前磨牙区和尖牙区发现MLF。结论:CBCT可清楚显示下颌骨舌侧孔的数量和位置,为临床应用提供参考。
Objective: To evaluate the imaging features of mandibular lingual foramina (MLF) by cone-beam computed tomography (CBCT). Methods: CBCT images of 567 patients were randomly selected from the Huaxi Stomatological Hospital Image Database of Sichuan University to observe the number, location and frequency of lingual holes in the mandible. Results: There were 1203 MLFs in CBCT images of 567 patients. 555 patients found MLF in the midline of the mandible, accounting for 97.88% of the total number of samples. 217 cases (38.27%) and 59 cases (10.41%) were found MLF in premolar area and canine area respectively. Conclusion: CBCT can clearly show the number and location of lingual holes in the mandible and provide a reference for clinical application.
