The purpose of the present study was to investigate and determine the anatomical relationship between the antilingula, lingula, and mandibular foramen using cone-beam computed tomography (CBCT).
CBCT images of 90 participants (180 mandibular ramus) were collected. The locations of and distances between the antilingula, lingual, and mandibular foramen according to side (right and left) and skeletal patterns were measured and then evaluated by statistical analysis.
Only 27 participants (15%) had bilateral distinct antilingula, lingula, and mandibular foramen. The antilingula was located anteriorly (4.28 mm and 3.59 mm) and above (1.99 mm and 8.52 mm) the lingula and mandibular foramen. The lingula was behind (0.69 mm) and above (6.53 mm) the mandibular foramen. Skeletal Class III was anterior and inferior to Class II and Class I in the antilingula, lingula, and mandibular foramen. Considering the correlations of landmarks, we found that the lingula was strongly correlated with the mandibular foramen on the X axis (r = 0.757) and Y-axis (r = 0.878).
The antilingula is located anteriorly and above the lingula and mandibular foramen. The lingula is behind and above the mandibular foramen. The osteotomy line of orthognathic surgery can only be safely designed through actual measurement of the locations of the antilingula, lingula, and mandibular foramen.
本研究旨在通过锥形束 CT（CBCT）研究并确定反舌隆突、舌隆突和下颌孔之间的解剖关系。
收集 90 名参与者（180 个下颌支）的 CBCT 图像。根据侧别（右侧和左侧）和骨骼形态测量反舌隆突、舌侧和下颌孔的位置和距离，然后进行统计学分析。
只有 27 名参与者（15%）双侧存在明显的反舌隆突、舌隆突和下颌孔。反舌隆突位于舌隆突和下颌孔的前方（4.28mm 和 3.59mm）和上方（1.99mm 和 8.52mm）。舌隆突位于下颌孔的后方（0.69mm）和上方（6.53mm）。下颌孔在反舌隆突、舌隆突和下颌孔中，骨骼形态 III 类位于 II 类和 I 类的前方和下方。考虑到标志点的相关性，我们发现舌隆突与下颌孔在 X 轴（r=0.757）和 Y 轴（r=0.878）上相关性较强。
反舌隆突位于舌隆突和下颌孔的前方和上方。舌隆突位于下颌孔的后方和上方。正颌手术的截骨线只能通过实际测量反舌隆突、舌隆突和下颌孔的位置来安全设计。
