Foramen Vesalius (Emissary Sphenoidal Foramen) is an inconstant foramen of skull.
Amac: Bu calismadaki amac morfolojik olarak foramen mentalenin pozisyon tiplerini, varyasyonunu ve asimetrisini arastirmaktir.
(Vertucci, 2005; Wu et al, 2017) An especially critical part of the cleaning and shaping procedures rests on the knowledge of the characteristics of the apical terminus of the preparation, that is the physiological foramen or apical constriction, in order to determine the final size of the preparation (Marroquin et al., 2004) and the type of instrument or instrumentation technique, that will be required in order to obtain a properly shaped canal (Wu et al., 2000).
Opening (foramen) existing in one or both plates of the thyroid cartilage, which may or may not contain a neurovascular component is known as Foramen Thyroideum (FT).
The small foramen venosum (FV) is generally situated posteromedially to the foramen rotundum and anteromedially to the foramen ovale, the foramen spinosum and the carotid canal, with the foramen ovale being the closest structure to the FV (Chaisuksunt et al, 2012).
Despite the existence of studies about the identification of the AFMR in adults, does not exist, to this moment, scientific reference values that allows one to locate the AFMR in relation to the Mandibular Foramen (MF) and the Mandibular Lingula (ML)--strategic anatomic landmarks that must be considered when the inferior alveolar nerve block or surgical procedures in the mandibular ramus are necessary (Malamed; Trauner & Obgeser, 1957a, 1957b).
One such foramen is the Foramen Spinosum (FS) which is located in close proximity postero-lateral to Foramen ovale (FO) and transmits the middle meningeal vessels, the meningeal branch of mandibular nerve and the nervous spinosus (Dogan et al.; Srimani et al., 2014).
In the jaw, besides the constant holes as the mental and the mandibular foramen, there are a great quantity of foramina and accessory foramina, which have been associated with to situations of clinical interest.
The orientation and position of the mental foramen is important to performing anesthetic block prior to clinical procedures in lower-anterior teeth and also to preserve the integrity of the mental nerve trunk in surgical interventions (Julian et al., 1998; Cutright et al., 2003; Mwaniki & Hassanali, 1992).
Approximately in 99% of the cases, it was observed that foramens obeyed the following relation: if one were medial (in relation to the sagital plain that passed by the zigomatic-maxilar suture when the same crossed the infraorbital margin) the other was either, or if one were lateral to the to the plain, the other was too.
