The aim of this article is to present a case of an accessory mental foramen (AMF).
The mental foramen is an important anatomical structure of particular importance in local anesthesia and surgical procedures in terms of achieving effective mandibular nerve blocks and avoiding injuries to the neurovascular bundles. Although rare, multiple mental foramina have been described in humans. In these cases one foramen is termed the mental foramen and the others are referred to as an AMF.
A 62-year-old woman presented for a routine dental examination. In addition to the normal radiographic image of the mental foramen, periapical radiographs of the left mandibular premolar and molar region revealed a round-shaped radiolucency with distinct borders along with an inferior extension below the apex of the mesial root of the first molar. This image was considered to be an AMF.
Although no surgical operation was planned, the patient was informed about the existence and importance of the anatomical variation with regard to the need for local anesthesia, diagnosis of periapical disease, and the prevention of nerve damage during surgery in that area of the mandible.
本文旨在呈现一例副颏孔（AMF）病例。
颏孔是一个重要的解剖结构，在局部麻醉和外科手术中，对于实现有效的下颌神经阻滞以及避免损伤神经血管束尤为重要。虽然人类中多个颏孔的情况较为罕见，但已有相关描述。在这些病例中，一个孔被称为颏孔，其他的则被称为副颏孔。
一名62岁女性前来进行常规牙科检查。除了颏孔的正常影像学图像外，左下颌前磨牙和磨牙区域的根尖片显示出一个边界清晰的圆形透射区，并且在第一磨牙近中根根尖下方有向下的延伸。此图像被认为是一个副颏孔。
尽管未计划进行手术，但已告知患者该解剖变异在下颌该区域局部麻醉需求、根尖周疾病诊断以及手术中预防神经损伤方面的存在情况和重要性。
