Accessory mental foramen: A rare anatomical variation detected by cone-beam computed tomography.

Torres MG, Valverde Lde F, Vidal MT, CrusoƩ-Rebello IM - Imaging Sci Dent (2015)

Bottom Line: The mental foramen is a bilateral opening in the vestibular portion of the mandible through which nerve endings, such as the mental nerve, emerge.In general, the mental foramen is located between the lower premolars.In the hemimandible, the mental foramen normally appears as a single structure, but there are some rare reports on the presence and number of anatomical variations; these variations may include accessory foramina.

ABSTRACT
The mental foramen is a bilateral opening in the vestibular portion of the mandible through which nerve endings, such as the mental nerve, emerge. In general, the mental foramen is located between the lower premolars. This region is a common area for the placement of dental implants. It is very important to identify anatomical variations in presurgical imaging exams since damage to neurovascular bundles may have a direct influence on treatment success. In the hemimandible, the mental foramen normally appears as a single structure, but there are some rare reports on the presence and number of anatomical variations; these variations may include accessory foramina. The present report describes the presence of accessory mental foramina in the right mandible, as detected by cone-beam computed tomography before dental implant placement.

Figure 5: The accessory mental foramen is not detected on the panoramic radiograph.

Mentions: Three-dimensional reconstruction demonstrated the presence of two mental foramina on the right side and only one, of wider diameter, on the left side (Fig. 4). In the panoramic radiograph, we could not observe the presence of the accessory mental foramen (Fig. 5).
