Submental lymph node level

NCBI Bookshelf. Murtaja Z. Al-Missri ; Yasir Al Khalili. Authors Murtaja Z. Al-Missri 1 ; Yasir Al Khalili 2. 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].

Submental lymph node hard

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]. The neck is anatomically bounded by the inferior border of the mandible, the superior border of the clavicle, the midline, and the anterior border of the trapezius muscle.

Two main cervical triangles are described between these limits, anterior and posterior. The posterior triangle is divided into an occipital and a supraclavicular triangle; the anterior triangle contains three paired triangles muscular, carotid, and submandibular and one unpaired space: the submental triangle. The boundaries of the anterior cervical triangle include the anterior margin of the sternocleidomastoid muscle, the midline of the neck, and the inferior border of the mandible [1].
