Buccopharyngeal fascia

Buccopharyngeal fascia is a layer of the deep cervical fascia that envelops the pharynx and the buccinator muscle. It is a thin layer of connective tissue that separates the pharynx and buccinator muscle from the other structures of the neck and face.

Etymology

The term "buccopharyngeal" is derived from the Latin words "bucca" meaning cheek and "pharynx" meaning throat. "Fascia" is a Latin term meaning band or bandage, referring to the band-like nature of this type of connective tissue.

Anatomy

The buccopharyngeal fascia is a continuation of the visceral fascia of the neck. It covers the buccinator muscle and the pharynx, separating them from the parotid gland, masseter muscle, and the mandible. It also extends to the base of the skull, where it is continuous with the pharyngobasilar fascia.

Function

The buccopharyngeal fascia serves as a protective barrier, preventing the spread of infections from the oral and nasal cavities to the neck. It also provides structural support to the pharynx and buccinator muscle, helping to maintain their shape and position.

Clinical significance

Infections or injuries to the buccopharyngeal fascia can lead to complications such as deep neck infection or Ludwig's angina. These conditions can be life-threatening if not treated promptly.
