Pharyngobasilar fascia

Dr Henry Knipe and Dr Aaron Rayan et al.

The pharyngobasilar fascia is the part of the middle layer of deep cervical fascia that attaches the pharynx to the skull base. It originates between the mucosal and muscular layers of the pharynx and is the primary component of the pharyngeal wall above the level of the superior pharyngeal constrictor muscle.

Gross anatomy

The pharyngobasilar fascia is a part of the middle layer of deep cervical fascia that surrounds the pharynx, along with the buccopharyngeal fascia.

The pharyngobasilar fascia provides structure to the lateral nasopharyngeal walls and helps maintain patency of the airway.

The sinus of Morgagni is a defect in the anterior aspect of the pharyngobasilar fascia, containing the eustachian tube and levator veli palatini muscle 4,8.

Relations and/or Boundaries

The pharyngobasilar fascia lies between the levator and tensor veli palatini muscles 7. It is a submucosal plane, located between the mucosa and muscularis layers.
