Background: Mandibular foramen is an irregular foramen located just above the centre of the medial surface of the ramus of the mandible. Mandibular foramen is leading to mandibular canal through which inferior nerve  and vessels will transmit and supply the teeth of lower jaw.

The Mandibular foramen is an important anatomical landmark for the inferior nerve blocks, mandibular osteotomies and implant treatment. The inferior nerve block is the commonest local anaesthetic technique which is used for  anaesthetizing lower jaw in various surgical and dental procedures  on mandible and mandibular teeth  such as removal of impaction, reduction of fractures and tooth extraction. Inferior alveolar nerve block failure is not uncommon and it occurs even with experienced hands  due to variations in position of mandibular foramen.

A thorough knowledge of anatomy  of mandibular foramen is very essential hence aim of this study was to determine the exact position of  mandibular foramen by studying dry adult human mandibles of telangana  population.

Material and methods: The present study was conducted using 60 dry adult human mandibles obtained from anatomy department of Shadan institute of medical sciences,Hyderabad and VRK womens medical college,Hyderabad. The data was tabulated and statistically analysed.

Result: The mean distance of mandibular foramen to anterior border of ramus (MF-AB)was16.67±2.73mm(R)and 16.56±2.52mm(L),to posterior border of ramus(MF-PB) was 12.67±2.37mm(R) and 13.03±2.43mm(L),to mandibular notch (MF-MN) 21.04±2.95mm(R) and 20.24±2.94mm(L),to angle of mandible was 23.005±3.92mm(R) and 22.36±3.89mm,base of mandible or inferior border (MF-MB) was 24.38±3.86mm(R)  and 24.42±4.44mm(L), tip of coronoid process (MF-CrT) 35.68±3.25mm(R) and 35.19±3.47mm (L).

Conclusion: The present study gives a fair knowledge of the position of mandibular foramen and provides useful information for  successful  local anaesthesia ( inferior nerve block),to the maxillofacial surgeons,radiologists and oncologists performing operations on the mandible to prevent complications and misinterpretations
