Introduction: Morphometric analysis of mandibles is clinically important due to the close relationship of lingula with neurovascular structures. Lingula is considered a bony landmark during the maxillofacial surgical approaches. The antilingula is a bony prominence present on the lateral surface of the mandibular ramus, helpful to identify the position of mandibular foramen during oral surgery. Aim: The study aimed to determine the morphometric analysis of the antilingula and its relation to the lingula of the mandible. Materials and methods: In 30 dried mandibles distance from lingula and antilingula to the anterior, posterior, superior, and inferior borders of mandibular ramus was measured using a digital vernier caliper. Results: Average distance between superior border to Lingula 17.57 土 2.86 mm and Antilingula 15.06 土 3.22 mm; Inferior border to Lingula 27.42 土 2.58 mm and Antilingula 26.93土 3.53 mm; Anterior border to Lingula 16.36 土 1.73mm and Antilingula 15.31 土 2.97mm and posterior border to Lingula 16.15 士 2.32mm and Antilingula 14.86 士 2.29mm. Friedman’s two-way analysis of variance by ranks test was done and the p-value:0.00( p<0.05), it was statistically significant. Conclusion: The morphometric analysis of the antilingula and its relation to the lingula of the mandible was correlated and it was referred to as an important reference point for surgeons in the surgical field to localise the mandibular foramen for the variation in the position of the lingula.
