“…Valente et al [20] have measured the distance of mandibular foramen from the apex of retromolar trigone and reported it to be 14.23±2.57 mm on the right side and 14.40±2.48 mm on the left side. In the present study, the measurements were 12.27±2.13 mm on the right side and 12.13±2.35 mm on the left side.…”

The mandibular foramen is a landmark for procedures like inferior alveolar nerve block, mandibular implant treatment, and mandibular osteotomies. The present study was aimed to identify the precise location of the mandibular foramen and the incidence of accessory mandibular foramen in dry adult mandibles of South Indian population. The distance of mandibular foramen from the anterior border of the ramus, posterior border of the ramus, mandibular notch, base of the mandible, third molar, and apex of retromolar trigone was measured with a vernier caliper in 204 mandibles. The mean distance of mandibular foramen from the anterior border of ramus of mandible was 17.11±2.74 mm on the right side and 17.41±3.05 mm on the left side, from posterior border was 10.47±2.11 mm on the right side and 9.68±2.03 mm on the left side, from mandibular notch was 21.74±2.74 mm on the right side and 21.92±3.33 mm on the left side, from the base of the ramus was 22.33±3.32 mm on the right side and 25.35±4.5 mm on the left side, from the third molar tooth was 22.84±3.94 mm on the right side and 23.23±4.21 mm on the left side, from the apex of retromolar trigone was 12.27±12.13 mm on the right side and 12.13±2.35 mm on the left side. Accessory mandibular foramen was present in 32.36% of mandibles. Knowledge of location mandibular foramen is useful to the maxillofacial surgeons, oncologists and radiologists.

“…In humans, the position of the foramen seems to show symmetry between the right and left rami. Position also appears to be determined by the size, width and height of the mandible, being more posterior in a wider ramus [ 34 ]. However, there are few age-related changes in the relative position of the MF, particularly anterio-posteriorly from the alveolar crestal plane [ 35 ].…”

“…However, there are few age-related changes in the relative position of the MF, particularly anterio-posteriorly from the alveolar crestal plane [ 35 ]. Size also exerts little influence on the position of the MF relative to the occlusal plane of the molars, where it is either level or slightly below [ 33 ], tending to be lower in children [ 34 ]. These findings are consistent with those found in the elephant mandible (see Fig 3 ).…”

A Novel Objective Method of Estimating the Age of Mandibles from African Elephants (Loxodonta africana Africana)

The importance of assigning an accurate estimate of age and sex to elephant carcasses found in the wild has increased in recent years with the escalation in levels of poaching throughout Africa. Irregularities identified in current ageing techniques prompted the development of a new method to describe molar progression throughout life. Elephant mandibles (n = 323) were studied and a point near the distal dental alveolus was identified as being most useful in ranking each jaw according to molar progression. These ‘Age Reference Lines’ were then associated with an age scale based on previous studies and Zimbabwean mandibles of known age. The new ranking produced a single age scale that proved useful for both male and female mandibles up to the maximum lifespan age of 70–75 years. Methods to aid in molar identification and the sexing of found jaws were also identified.

“…Situated at the centre of the medial aspect of the mandibular ramus, inferiorly and posteriorly to the lingula, the mandibular foramen shows no differences regarding shape, size and location when comparing its features on the left and right side of the mandible (Iwaki et al;Valente et al;Ennes & Medeiros, 2009;Martone et al, 1993).…”

“…Studies on the location of the mandibular foramen (MF) provide the practitioner with improved awareness of MF location, thus, lowering the risk of having the inferior alveolar nerve injured, as well as improving the efficacy of inferior alveolar nerve block (Nicholson, 1985;Daw et al, 1999;Valente et al, 2012;da Fontoura et al, 2002).…”

Mandibular Foramen Location and Lingula Height in Dentate Dry Mandibles, and its Relationship With Cephalic Index

et al. 2015

SUMMARY:The mandibular foramen and its lingula is a major landmark when administering anesthetic or performing surgical procedures. The objective of this study was to determine whether the topological features of the mandibular foramen (MF) and lingula varied in mandibles from skulls of different cephalic indexes. The location of the mandibular foramen referred to the longitudinal borders of the mandibular ramus (MR), height of the foramen (Hf) referred to the occlusal line of the second molar, and the height of the lingula (Hl) were determined in a total of one hundred and five dry mandibles from skulls identified as dolicho-meso-and brachycephalic. On average MF in brachycephalic mandibles was closest to the anterior border of MR. Hf in brachy-, meso-and dolichocephalic mandibles were -0.22 mm, -4.04 mm and -4,01mm, respectively. The lingula in brachycephalic specimens was considerably shorter (0.78 mm) than in dolichocephalic ones (1.84 mm). Inferior alveolar nerve block should be carried out using shorter needles, inserting it 4mm above the occlusion level of the molar teeth. The ramus of brachicephalic mandibles were significantly less wide those of dolicho-and mesocephalic ones. If the height of the lingula is to be used as a reference to judge the level of the medial horizontal cut to carry out sagittal split ramus osteotomy, special attention should be given to the patient's cephalic index.
