Prevalencia de variantes anatómicas de língula mandibular en 100 tomografías Cone Beam en adultos, Studio3D Guayaquil, 2018.

Abstract

Introduction: The lingula is a bony projection with a tongue-like shape on the medial surface of the mandibular ramus near the posterior margin of the mandibular foramen. Objective: the objective of this work is to determine the prevalence of anatomical alternatives of the evaluation line in male and female subjects using Cone Beam computed tomography. Materials and Methods: the research is descriptive cross-sectional in which 100 Cone Beam computed tomographies are evaluated, in which the different anatomical variants are evaluated with respect to the shape, height and location of the mandibular lingula in adult individuals that the tomographies were performed in the 3D diagnostic radiology center in 2018. Results: 36% of the studied population presented the variant in nodular form, 24.5% the triangular form, 20% the truncated form and the 19,5% the assimilated form. This anatomical relief was located more towards the posterior edge of the mandibular branch. Conclusion: The bilateral nodular form of the lingula was more common in the study population and in each sex, followed by the triangle, truncated and finally the assimilated. The average height of the lingula was 6.91 mm.
