To investigate by means of CBCT the presence of lingual foramina and their bony canals in the midline of the mandible and to describe their anatomical characteristics.
CBCT examinations of 36 patients were carefully examined in the median region of the mandible in order to detect the lingual foramina and their corresponding vascular canals. Their presence, number, position, diameter and trajectory were established.
Lingual foramina in the midline of the mandible were observed in all 36 subjects. The number of canals varied from one to four, with the following distribution: one canal in 71.9% of the cases, two canals in 9.4%, three in 15.6%, and four canals in 3.1% of the cases. The average diameter of the canals was 0.84 mm. The average distance from the foramina to the base of the mandible was of 11.2 mm. 19.4% of the vascular canals penetrated only the lingual third of the width, 52.8% reached the middle third of the mandible and 27.8% of the canals spread to the buccal third.
CBCT is a useful tool in planning an implant treatment. It can reveal multiple anatomic features of the mandible, including the presence and the morphology of the lingual foramina and their vascular canals in the median region of the mandible. Clinicians should acknowledge the presence of these anatomical structures and should be aware of their possible implications.
通过锥形束计算机断层扫描（CBCT）研究下颌骨中线处舌孔及其骨管的存在情况，并描述其解剖特征。
对36例患者的CBCT检查在下颌骨中线区域进行仔细观察，以检测舌孔及其相应的血管管道。确定它们的存在、数量、位置、直径和走行。
36例受试者均在下颌骨中线处观察到舌孔。管道数量从1条到4条不等，分布如下：71.9%的病例有1条管道，9.4%有2条，15.6%有3条，3.1%有4条。管道的平均直径为0.84毫米。舌孔到下颌骨底部的平均距离为11.2毫米。19.4%的血管管道仅穿透舌侧宽度的三分之一，52.8%到达下颌骨的中间三分之一，27.8%的管道延伸至颊侧三分之一。
CBCT是种植治疗计划中的一种有用工具。它可以揭示下颌骨的多种解剖特征，包括下颌骨中线区域舌孔及其血管管道的存在和形态。临床医生应认识到这些解剖结构的存在，并应意识到其可能的影响。
