Buccopharyngeal Fascia

fascia buccopharyngea

The buccopharyngeal fascia covers the outer surface of the pharyngeal constrictors and buccinator, forming the posterior boundary of the retropharyngeal space from the skull base to the mediastinum.

Region: Neck
Biomechanics

Function & Actions

Forms the outer fascial layer of the pharynx, provides the posterior wall of the retropharyngeal space, and serves as a surgical plane in anterior cervical approaches.

Clinical Relevance

Clinical Notes

In anterior cervical discectomy and fusion, the buccopharyngeal fascia is the last layer of the posterior pharyngeal wall traversed during the retropharyngeal approach. Scar formation in this fascia after anterior cervical surgery contributes to post-operative dysphagia.

Pathology

Common Injuries & Conditions

Post-operative Dysphagia from Fascia Scarring

Buccopharyngeal fascia adhesion to the anterior cervical plate following anterior cervical fusion, producing chronic dysphagia treated by revision of the plate or lysis of adhesions.
