“…Karthikeya Patil et al studied 25 Indian dry human adult mandibles and found that average mandibular ramus width was 30.2 mm. [8] In our study average mandibular ramus width was found to be 30.68 ± 2.75 mm on the right side and 30.50 ± 2.71 mm on the left side. Distance between mandibular foramen and anterior border of ramus was found to be 16.93 ± 1.54 mm and between mandibular foramen and posterior border of ramus was found to be 13.33 ± 1.57 mm by Karthikeya Patil et al, which is close to the results of our study.…”

“…These variations occur due to racial differences, craniofacial growth and anatomical variability. [8,9] Hence, mandibular foramen should be accurately located before initiating any surgical procedure. The aim of this study is to determine the position of the mandibular foramen from various anatomical landmarks in several dry adult human mandibles and provide valuable information to our students and dental practitioners.…”

Background:The mandibular foramen is located on the medial surface of ramus of mandible. It transmits inferior alveolar nerve. Inferior alveolar nerve block is a common procedure done by dental practitioners while doing various surgeries on mandible. The aim of this study is to determine the position of mandibular foramen in respect to various landmarks present on mandible. Methods: 30 adult human dry mandibles of north Indian origin were studied. The position of mandibular foramen from various landmarks was measured on both sides of mandibular ramus. Results: In our study we found the mean distance from the mandibular foramen to the anterior border of the ramus was 16.06±1.99 mm and 16.13±2.10 mm on the right and left sides respectively and from the mandibular foramen to the posterior border of the ramus was 12.02±1.99 mm and 11.10±1.95 mm on the right and left sides respectively. The mandibular foramen was situated at a mean distance of 1.36±0.77 mm on the right side and 1.47±0.72 mm on the left side, posterior to the midpoint of width of the ramus and at a mean distance of 3.37±1.37 mm on the right side and 3.10±1.41 mm on the left side, superior to the midpoint of vertical height of the ramus. Conclusion: In present study localization of mandibular foramen presented great variation. However if we keep these anatomical landmarks in our mind we can accurately locate the position of mandibular foramen and this will help us to create successful anesthesia and to perform good surgeries on mandible.

“…Finally, the differences with our study could be explained in four different ways: (1) the mandibular lingula was located above the MF, with great variation in the ML-MF distance [16,28] and its anatomical forms [25]; (2) panoramic radiographs might be subject to deformations [31] and the distances measured on dry mandibles and panoramic radiographs have showed significant differences [32]; (3) in three of these studies, the OP was drawn by hand; (4) ethnic Fig. 3 Evolutions of the measurements through dental age.…”

Objectives The location of the mandibular foramen is essential for the quality of the inferior alveolar nerve block anaesthesia and has often been studied with contradictory results over the years. The aim of this study was to locate the mandibular foramen, according to the dental age of the subject, through 3D analysis. Methods Three-dimensional images were reconstructed from mandibular computed tomography of 260 children, adolescents and adults. The occlusal plane was determined as the average plane passing through the buccal cusps of mandibular molars, premolars, and canines, and through the incisor edge. The mandibular foramen was located three dimensionally in relation to the anterior edge of the ramus (or coronoid notch), the sagittal plane and the occlusal plane. Results All along mandibular growth, the three distances defining the relative position of the mandibular foramen showed negligible changes. The mandibular foramen is located from − 0.4 to 2.9 mm above the occlusal plane. The distance between the mandibular foramen and the leading edge of the mandibular ramus ranged from 17 to 19.5 mm. The angle between the ramus and the sagittal plane ranged from 3° to 5.4°. Conclusion In our sample, and using the occlusal plane and the anterior edge of the ramus as anatomical references, the location of the mandibular foramen was considered to be similar in all patients regardless of age.

“…The lingula is used for defining the site for injection of local anaesthetics for inferior alveolar nerve. However, the location of mandibular foramen (MF) shows remarkable variation among several populations, in different ages and even within the same individual on two sides [20]. Variations in the form of the lingula have been reported by diverse authors [2,8,15], and Tuli et al [31] classified lingula into four different types based on its form namely triangular, truncated, nodular and assimilated types.…”

“…Some researchers have estimated the failure rate of inferior alveolar nerve blocks to be about 20-25% [23]. Therefore, MF should be accurately located before initiating any surgical procedure [20].…”
