The authors verified the anatomical location of the mandibular foramen, lingula and antilingula in dry mandibles, aiming to obtain information that could be used when performing mandibular osteotomies. Forty-four mandibles (88 sides) were evaluated. The distances were measured using a sliding calliper, with the mandibles fixed in a reproducible position. Results showed that the mandibular foramen is on average 5.82 mm below the lingula. Regarding the statistical comparison between the mandibular foramen entrance and the antilingula position, there is no correlation between the position of those two structures in the studied sample. The mandibular foramen is slightly posterior in relation to the centre of the ramus. The lingula is an important anatomic landmark for ramus surgery, and for determining the distance to the mandibular foramen entrance. The use of the antilingula as a landmark for the position of the vertical ramus osteotomy is not recommended.
作者验证了下颌孔、下颌舌骨嵴和反折线在干燥下颌骨中的解剖位置，旨在获得在进行下颌骨切开术时可以使用的信息。评估了 44 个下颌骨（88 侧）。使用滑动卡尺测量距离，下颌骨固定在可重复的位置。结果表明，下颌孔平均位于下颌舌骨嵴下方 5.82mm。关于下颌孔入口和反折线位置之间的统计比较，在研究样本中，这两个结构的位置没有相关性。下颌孔相对于下颌支中心稍微靠后。下颌舌骨嵴是下颌支手术的重要解剖标志，也是确定到下颌孔入口的距离的重要标志。不建议将反折线用作垂直下颌支切开术位置的标志。
