A fractal anterior digastric: a case report with surgical implications

A unique asymmetrical digastric muscle variant was discovered during glossectomy of a cadaver. The muscle gave rise to two smaller accessory bellies which, likewise, gave rise to another two smaller accessory bellies supported by a fascial sling. Although variant anatomy of the anterior belly of the digastric is common, we report a new structural presentation. Understanding the diverse anatomical variety among digastric muscles is particularly important with regard to both surgery and differential diagnosis of space occupying lesions in the submental triangle.
