The Variational Types of Anterior Belly of the Digastric Muscle and Clinical Importance: A Case Report

Abstract

In this study, we examined anatomical variations in the anterior belly of the digastric muscle (ABDM) in two cadavers: a 68-year-old male and a 54-year-old female. Variations in the length, diameter, and origin-insertion relationships were measured and categorized. The results showed unilateral insertion and origin types, emphasizing their clinical relevance in head and neck surgery and radiological assessments. © 2025 Elsevier B.V., All rights reserved.
