PURPOSE
The aim of this article is to investigate the potential risk of a critical life-threatening hemorrhage due to the perforation of the lingual cortical plate and arterial trauma of the terminal branches of the sublingual artery. In fact, in many cases, implants are placed in the mandibular interforaminal region, and this area is also often involved in oral surgery as a bone donor site.
MATERIALS AND METHODS
One hundred dry skull Caucasian mandibles and 100 computed tomographies (CTs) of the mandible of Caucasian patients were examined. The entrances of the lingual vascular canals were analyzed. Positions and dimensions of the entrances are reported.
RESULTS
In 80% of the dry skull mandibles, at least 1 lingual canal was found, and the CT scan detected the presence of at least 1 lingual vascular canal in up to 60% of patients.
CONCLUSIONS
A CT examination should routinely be performed before any surgical approach to the interforaminal region.
目的
本文旨在研究因舌皮质板穿孔和舌下动脉终末支动脉损伤导致危及生命的严重出血的潜在风险。事实上，在许多情况下，种植体被放置在下颌孔间区域，并且该区域也经常作为骨供区参与口腔外科手术。
材料与方法
检查了100具白人干燥颅骨下颌骨以及100例白人患者的下颌骨计算机断层扫描（CT）。分析舌血管管的入口。报告了入口的位置和尺寸。
结果
在80%的干燥颅骨下颌骨中，至少发现1条舌管，CT扫描在高达60%的患者中检测到至少1条舌血管管的存在。
结论
在对孔间区域进行任何手术操作之前，都应常规进行CT检查。
