Because the digastric muscle is considered as an anatomical landmark, its variations may emphasize clinicians to be cautious during surgery. However, previous studies from different ethnicities reported a wide range of occurrence and several types this variation, pointing necessity data local population better treatment decisions. Thus, study aimed explore anterior belly in Thai cadavers.This cross-sectional investigated submental region 91 cadavers by convenient sampling method. The characteristics variation were recorded accordance with sex side cadavers. Multiple logistic regression was calculated for determining association sexes sides (α = 0.05).Among cadavers, accessory bundles observed 16 (10 males 6 females). presence additional independent. Three observed; arrowhead type double-headed have been previously reported, whereas asymmetrical fan-shaped new variant that has never described before.The including can seen Thais low occurrence. To our knowledge, present first report aberrations Southeast Asian population. Therefore, provides basis muscular variants helps surgeons plan operation prevent iatrogenic injuries.
