dc.description.abstract Correct detailed description of the anatomy of the digastric muscle (DM) in different populations should be carried out to improve the teaching of anatomy, avoid misinterpretations and help to avoid intercurrences during surgical procedures in the region. The aim of this study was to carry out a study of the DM in adult Brazilian individuals. The sample consisted of 50 DM from adult individuals (22 right side and 28 left side) fixed in 10 % formaldehyde. The morphology of the DM was observed, identifying possible anatomical variations; these were characterized and classified according to the number of the muscle bellies, direction of the fibre, and points of origin and insertion. The morphometric measurements were performed using a digital calliper. Student’s t-test for dependent samples was used to measure differences between sides; one-way ANOVA was used to analyse the different classifications, and the chi-squared test to analyse qualitative variables, with significance threshold of 5 %. The anterior belly of the DM was classified as Type I in 28 samples (56 %), Type II in 20 (40 %) and Type III in 2 (4 %). The mean length was 37.8 mm, width 12.1 mm and thickness 5.39 mm, with no statistically significant differences found for these variables. The intermediate tendon of the DM was classified as Type I in 31 samples (62 %), Type II in 10 (20 %) and Type III in 9 (18 %); its mean total length was 45.1 mm. The posterior belly of the DM was Type I in 50 samples (100 %), with mean length 70.8 mm and width 8.15 mm. Anatomical variations of the DM, particularly its anterior belly, in Brazilian adults are very frequent. They must therefore be carefully identified to help avoid intercurrences during surgical procedures in the region, and to help correct evaluation of swollen lymph nodes in the submental triangle. en
