Origin

The tonsillar branch of the facial artery arises from the facial artery most commonly; however, it may arise from the ascending palatine artery.

Course

The tonsillar branch of the facial artery ascends between the styloglossus and medial pterygoid muscles to reach the pharynx. At the superior border of the styloglossus muscle, the tonsillar branch pierces through the superior pharyngeal constrictor muscle to reach the inferior pole of the palatine tonsil.

Branches

There are no named branches.

Supplied Structures

The tonsillar branch of the facial artery provides the main blood supply to the palatine tonsils and superior pharyngeal constrictor muscle.

Facial Artery

The facial artery arises as a proximal branch of the ECA (either directly or as a common trunk with the lingual artery), ascends superficial to the mandible, then courses medially in the superficial soft tissues of the face, giving off branches to the lips, mandible, cheeks, and nasal cavity.
