Abstract

Introduction: The mandibular nerve and the mental foramen have occasionally shown variations in its anatomy. This report aims to present a case of lingual mental foramen recognised on three-dimensional cone beam computed tomographic imaging (CBCT).

Case report: Routine Orthopantomogram (OPG) and CBCT images were evaluated to assess the status of impact third molars in a 31-year-old female who had visited the dental clinics in our institution. The OPG image failed to reveal any anatomic variation in the position of the mental foramen. On tracing the course of the mandibular canal in CBCT images, two foramina were traced at the region of premolar. One opened towards the buccal cortical plate at the normal position of the mental foramen and an accessory lingual mental foramen had an opening on the lingual cortical bone at the same level as the mental foramen.

Conclusion: Understanding variations of the mental foramen is extremely essential in dentistry to carry out successful anaesthetic or surgical interventions and to avoid complications such as nerve damage or excessive bleeding.

附属舌侧精神孔：一例罕见的解剖变异报告。

导言下颌神经和精神孔的解剖结构偶尔会发生变化。本报告旨在介绍一例在三维锥形束计算机断层扫描成像（CBCT）中被识别为舌侧精神孔的病例：病例报告：本院牙科诊所曾对一名 31 岁女性的常规正侧位图（OPG）和 CBCT 图像进行评估，以评估其第三磨牙的撞击状态。OPG 图像未能显示出心孔位置的任何解剖变化。在 CBCT 图像中追踪下颌管的走向时，在前磨牙区域发现了两个孔。其中一个开口朝向颊皮质板，位于心耳孔的正常位置，而另一个附属的舌侧心耳孔开口位于舌侧皮质骨上，与心耳孔处于同一水平：要成功实施麻醉或手术干预，避免神经损伤或出血过多等并发症，了解齿状突孔的变化在牙科中至关重要。
