Structure

The buccopharyngeal fascia is part of the visceral division of the deep cervical fascia. It commences laterally as it fuses with the periosteum on the posterior alveolar process of the maxilla and the periosteum of the medial pterygoid plate of the sphenoid bone. The fascia travels posteriorly to cover the buccinator muscle and the lateral parts of the superior pharyngeal constrictor muscle before curving posteromedially to cover the back of the superior pharyngeal constrictor (Stecco & Hammer, 2014). It descends in the midline to cover the posterior aspect of middle and inferior pharyngeal constrictor muscles.

Function
