Bioengineering, Vol. 10, Pages 170: Morphological Study of the Mandibular Lingula and Antilingula by Cone Beam Computed Tomography Bioengineering doi: 10.3390/bioengineering10020170 Authors: Chun Ming Chen Hui Na Lee Shih Wei Liang Kun Jung Hsu The patterns of the lingula and antilingula are crucial surgical reference points for ramus osteotomy. Cone beam computed tomography (CBCT) provides three dimensional images, and patient radiation dose is significantly lower for CBCT than for medical CT. The morphology of the mandibular lingula and antilingula of ninety patients (180 sides) were investigated using CBCT. The lingula were classified as having triangular, truncated, nodular, and assimilated shapes. The antilingula were classified as having hill, ridge, plateau, and plain shapes. The patients sex, skeletal patterns (Classes I, II, and III), and right and left sides were recorded. The most to least common lingula shapes were nodular (37.8%), followed by truncated (32.8%), triangular (24.4%), and assimilated (5%). The most to least common antilingulae were hill (62.8%), plain (18.9%), plateau (13.9%), and ridge (4.4%) patterns, respectively. The lingula and antilingula had identical patterns on both sides in 47 (52.2%) and 46 patients (51.1%), respectively. Sex and skeletal pattern were not significantly correlated to lingula and antilingula shapes. No significant correlation was observed between lingula and antilingula shapes.
