El foramen mentoniano accesorio es un orificio adicional al foramen mentoniano que se localiza en la cara anterolateral externa del cuerpo mandibular y que se conecta con el conducto dentario inferior.  Su ubicación es posteroinferior al foramen mentoniano.  De acuerdo a su clasificación también se lo conoce como foramen mental doble, foramen mental adicional, foramen mental múltiple, foramen mental accesorio o foramen mandibular bucal suplementario. Su frecuencia de aparición varía del 1% al 10 %, cuando son unilaterales y del 0,47% al 1,2% cuando son bilaterales.  El  foramen mentoniano accesorio es una rara variante anatómica de poca frecuencia pero de gran relevancia clínico-quirúrgica ya que está asociado a un paquete vasculonervioso por lo cual es necesario su diagnóstico radiográfico ya sea por métodos convencionales o por alta resolución para evitar posibles complicaciones en los diferentes procedimientos odontológicos. Se presenta un caso de foramen mentoniano accesorio de un paciente remitido al Servicio de Radiología de la Facultad de Odontología de la UNC. La tomografía computada constituye el estudio por imágenes de excelencia ante la presunción de un foramen accesorio ya que los diferentes cortes tomográficos y la reconstrucción 3D nos permiten localizarlo de manera precisa e inequívoca. Constituye generalmente un hallazgo radiográfico o se observa durante procedimientos quirúrgicos al quedar al descubierto por el desplazamiento de los tejidos blandos. Cuando se localiza antes de cualquier procedimiento odontológico se deben tomar todos los recaudos necesarios para evitar daño del paquete vasculonervioso y futuras complicaciones como hemorragias o parestesias, principalmente en prácticas como la colocación de implantes dentales o las apicectomías. Accessory mental foramen (AMF) is defined as any openings in addition to mental foramen, with connection to the mandibular canal in the anterolateral aspect of mandible. According to its classification, an AMF is known as double mental foramen, additional mental foramen, multiple mental foramen, supplementary mandibular buccal foramen. The accessory mental foramen is a radiological finding or is detected during surgical procedures. Its prevalence ranges from 1.4 to 10% when it is unilateral and ranges from 0,47% to 1,2% when it is bilateral. Accessory mental foramen is an important and rare anatomical variation associated with a neurovascular bundle. Its prevalence is low. The diagnosis by conventional radiological methods or three-dimensional radiographic imaging techniques is effective to avoid complications in dental procedures. An accessory mental foramen case of a male patient referred to the Department of Radiology at the National University of Córdoba School of Dentistry is reported. The computed tomography is the most accurate imaging modality for the identification of an accessory foramen through multiplanar reformatted images and three dimensional images. When the existence of AMF is identified before dental procedures, appropriate actions should be taken to avoid damages of the neurovascular bundle and eventual complications such as hemorrhage and paresthesia principally in procedures like dental implant insertion or periapical surgery.

The mental foramen (MF) and accessory mental foramen (AMF) are the strategically important landmarks during surgical interventions and anaesthetic nerve blocks procedures involving the mental nerve. The study aimed at evaluating anthropometrics of MF and AMF in Zambian adult human mandibles and it was cleared for ethics from TDRC Ethics Review Committee (Reg. No.: 00002911; FWA: 00003729). A total of 33 Zambian adult human mandibles were evaluated for shape, position, and direction of opening of foramen. All measurements were performed using a Digital Vernier Calliper and statistically analysed for per cent frequency and mean and standard deviations, and we performed the one sample t-test for comparative analysis. Data were considered significant at p<0.05. All mandibles that were examined had bilateral MF while unilateral AMF was found in two mandibles (6%). The foramens were mostly oval in shape and their most common position was between the second premolar and first molar and the most common orientation was posterior-superior. The comparative analysis of mandibular anthropometrics showed significant variations (p<0.05) with different ethnic groups. The findings emphasize the ethnic variations and edify that the foramen position is not always as stated in reference textbooks. The clinical creditability of the study is cautioning the surgeons on possible variations of the MF and AMF anthropometrics compared to existing literature in order to avoid any unforeseen injury related to anaesthesia or dental surgeries. Further studies with large sample sizes representing whole country are recommended to establish the standard MF and AMF anthropometrics of Zambian population.

Objective: The aim of the present study was to clarify the occurrence, diameter, and location of the accessory mental foramen (AMF) using cone-beam computed tomography (CBCT) images from a sample of Turkish children. Study design: This retrospective was carried out using a total of 275 CBCT images from child and adolescent patients were randomly selected from existing records in the Department of Oral and Maxillofacial Radiology at the University of Erciyes, Kayseri, Turkey. The mental foramen (MF) and AMF were assessed on axial, sagittal, and coronal CBCT slices. Results: The mean age was 10.51 ± 3.32 years, consisting of 139 males (mean age 10.64 ± 3.42) and 126 females (mean age 10.38 ± 3.18). Twenty-one AMFs were observed in 18 of 275 patients (6.5%, 10 boys and eight girls). There was no significant difference in gender in relation to the prevalence of AMF (p = 0.65). The mean area of the 21 AMFs and the MF on the side with the AMF were 0.7 mm2 (SD ± 0.5) and 3.8 mm2 (SD ± 2.2), respectively. Conclusion: It is important to stress that detecting the AMN using CBCT with 3D reconstructions may reduce the risk of paralysis, hemorrhage, and postoperative pain in this region. Our study presents the first report assessing the occurrence, diameter, and location of the AMF in the pediatric population using CBCT images. In this respect, not surprisingly, the mean size of the AMF of our population is smaller than other reports in the literature that involve adult populations.
