Beclard Triangle

Beclard's Triangle is an anatomical region of the human body, specifically located in the neck. It is named after Pierre Augustin Béclard, a French anatomist who first described it in the 19th century.

Anatomy

Beclard's Triangle is a small, triangular area in the neck, bounded by the hyoid bone superiorly, the anterior belly of digastric muscle inferiorly, and the stylohyoid muscle posteriorly. The floor of the triangle is formed by the mylohyoid muscle, and the roof by the platysma muscle and skin.

Clinical Significance

The importance of Beclard's Triangle lies in its relation to the hypoglossal nerve, which passes through it. This nerve is responsible for the motor innervation of the tongue, and damage to it can result in hypoglossal nerve palsy, leading to difficulties in speech and swallowing.
