Author(s): Sakshi Mathur, Puneet Joshi
Abstract: Introduction: The Mandibular foramen (Mf) is an important anatomical landmark for the inferior alveolar nerve blocks, mandibular osteotomies & implant treatment. A thorough knowledge of the anatomy of the mandibular foramen is very essential hence this study aims to determine the position of Mf by studying dry human mandibles of Indian population in Rajasthan State. Materials and Methods: The present study was conducted using 100 dried human mandibles out of which 79 were dentulous and 21 were edentulous. Results: The average mean distance from the lowest point of mandibular notch (Mn) to the inferior limit of the Mf i.e. (Mn-Mf) was 22.65 ±4.33 mm (right side) and 22.94±3.46 mm (left side), from the midpoint of the anterior border of the Mf to the nearest point on the anterior border of the ramus (Ab) i.e. (Ab-Mf) was 15.72±2.57 mm (right side) and 16.02±2.28 mm (left side), from the midpoint of the posterior border of the Mf to the nearest point on the posterior border of the ramus (Pb) i.e. (Pb-Mf) is 11.39±1.87 mm (right side) and 11.58±1.93 mm (left side) and from the inferior limit of Mf to the furthest point on the angle of the mandible (Ag) i.e. (Mf-Ag) is 21.33±3.52 mm (right side) and 21.28±3.22 mm (left side). Conclusion: The present study gives a fair knowledge of the position of Mf and provides useful information regarding the success rate of local anaesthesia, to the maxillofacial surgeons, radiologists and oncologists performing operations on the mandible to prevent complications and misinterpretations.
