The presence of accessory mental foramina (AMF) is an important consideration prior to any dental implant and surgical treatment to avoid injury to the neurovascular bundle and subsequent postoperative complications. The aim of this retrospective study was to determine the prevalence of AMF from a substantially large sample of the Australian population. The cone beam computed tomography (CBCT) scans of 4,000 patients showing the mandible were examined. All mental foramen (MF) were visualized and no cases were excluded. The number of MF/AMF, sex, and age were recorded. The prevalence of AMF was found to be 6.4% (254 patients) in this study. Twelve patients exhibited bilateral AMF, and 11 had three mental foramina on one side. One case had a total of five mental foramina with three on the right and two on the left side. No significant sex preference was discovered. This is the largest study ever to be conducted to evaluate the prevalence of AMF. With nearly one in 15 individuals found to have AMF, clinicians must be acutely aware of this anatomical variation and treatment plan for each case accordingly. Clin.

存在副颏孔（AMF）是任何牙科植入物和手术治疗前的一个重要考虑因素，以避免损伤神经血管束和随后的术后并发症。本回顾性研究的目的是从澳大利亚人口的大量样本中确定 AMF 的患病率。检查了 4000 名显示下颌骨的锥形束计算机断层扫描（CBCT）扫描。所有颏孔（MF）均可见，无排除病例。记录了 MF/AMF 的数量、性别和年龄。在这项研究中，发现 AMF 的患病率为 6.4%（254 例）。12 例患者表现为双侧 AMF，11 例患者一侧有三个颏孔。一例共有五个颏孔，右侧三个，左侧两个。没有发现明显的性别偏好。这是迄今为止评估 AMF 患病率的最大规模研究。近 15 分之一的人被发现有 AMF，临床医生必须敏锐地意识到这种解剖变异，并相应地为每个病例制定治疗计划。临床解剖学 32:1048-1052，2019. © 2019 Wiley Periodicals, Inc.
