Trigonum hypoglossi

Trigonum Hypoglossi is a term used in anatomy to describe a specific region in the human body. It is also known as the sublingual triangle, and is one of the two triangles found in the anterior triangle of the neck. The other triangle is the trigonum submandibulare.

Anatomy

The trigonum hypoglossi is a region located in the anterior part of the neck. It is bounded by the hyoid bone inferiorly, the anterior belly of the digastric muscle anteriorly, and the posterior belly of the digastric muscle posteriorly. The floor of the triangle is formed by the mylohyoid muscle, hyoglossus muscle, and the middle constrictor muscle of the pharynx.

Clinical Significance

Due to its location, the trigonum hypoglossi is of clinical significance in various medical conditions and procedures. It is often involved in surgeries of the neck, such as thyroidectomy and parathyroidectomy. In addition, it is also a key area in the diagnosis and treatment of head and neck cancer.
