The submental triangle is the only unpaired triangle of the anterior triangle of the neck. It is limited by the body of the hyoid bone and the anterior bellies of the digastric muscle. The mylohyoid muscles form the floor of the submental space. However, the submental triangle can be absent or distorted because the anterior belly of the digastric muscle varies in anatomy and may be absent [1]. This area is clinically relevant as it contains essential anatomical structures, such as the submental lymph nodes that may serve as good indicators to determine metastasis [1].
