The mental foramen (MF) represents an anatomical aperture situated on the anterior aspect of the mandible bilaterally and constitutes a significant reference point for surgical procedures. The purpose of this study was to evaluate the usefulness of ultrasonography (USG) in determining the location and dimension of the MF and its distance to the alveolar crest in comparison with cone-beam computed tomography (CBCT).
The study was conducted on 27 patients (13 males, 14 females) over 18 years of age (19-73 years) who applied to the Department of Dentomaxillofacial Radiology for a CBCT scan before planning of implant procedures. The vertical diameter of the MF and its distance from the alveolar crest were measured on CBCT cross-sectional slices and compared with the measurements obtained by USG.
A total of 54 MFs were evaluated. The measurements of the vertical diameter of MF and its distance to the alveolar crest were consistent between CBCT and USG (P = 0.262 and P = 0.551, respectively). In either technique, the vertical diameter of MF was significantly higher in males whereas the distance to alveolar crest was significantly higher in females (P < 0.001). No significant age differences were observed in USG and CBCT measurements regarding MF diameter and distance to the alveolar crest (P > 0.05) CONCLUSIONS: USG is as accurate as CBCT in measuring MF and associated alveolar crest and has the potential for the localization of vital anatomical structures with the advantage of no concern about ionizing radiation.

颏孔（MF）是位于下颌骨双侧前表面的一个解剖孔道，是外科手术的重要参考点。本研究的目的是评估超声检查（USG）在确定颏孔的位置和尺寸及其与牙槽嵴的距离方面的有效性，并与锥形束计算机断层扫描（CBCT）进行比较。
本研究对27例年龄超过18岁（19 - 73岁）的患者（13例男性，14例女性）进行，这些患者在计划种植手术前到口腔颌面放射科进行CBCT扫描。在CBCT横断面切片上测量颏孔的垂直直径及其与牙槽嵴的距离，并与USG获得的测量值进行比较。
共评估了54个颏孔。CBCT和USG测量的颏孔垂直直径及其与牙槽嵴的距离一致（P分别为0.262和0.551）。在两种技术中，男性的颏孔垂直直径显著更高，而女性到牙槽嵴的距离显著更高（P < 0.001）。在USG和CBCT测量中，关于颏孔直径和到牙槽嵴的距离，未观察到显著的年龄差异（P > 0.05）。结论：USG在测量颏孔及相关牙槽嵴方面与CBCT一样准确，并且具有定位重要解剖结构的潜力，其优点是无需担心电离辐射。
