了解下颌管的走向及其解剖变化在口腔外科手术中非常重要，特别是在修复前手术和骨内种植体的插入以及在涉及广泛萎缩的下颌骨的情况下准备可摘义齿的规划过程中。我们回顾了有关重复下颌管的文献，这些文献完全基于放射学检查结果。然后，我们将其与干燥下颌骨的检查和进一步的放射学研究进行比较。下颌骨肉眼检查中观察到的重复下颌管的发生率明显高于X光片显示的重复下颌管的发生率。据报道，一例涉及一种新的变异，即三重下颌管。
Knowledge of the course of the mandibular canal and its anatomic variations is of great importance in oral surgery, especially in preprosthetic operations and the insertion of endosteal implants and during the planning of removable dentures prepared in cases involving extensively atrophied mandibles. We review the literature on duplicated mandibular canals, which is based exclusively on radiologic findings. Then, we compare this with an examination of dry mandibles and further radiologic studies. The incidence of duplicated mandibular canals observed in macroscopic examinations of mandibles was substantially higher than that revealed by radiographs. One case involving a novel variation, a triple mandibular canal, is reported.
