The pterygoid hamulus is a hook-like process at the lower extremity of the medial pterygoid plate of the sphenoid bone of the skull. It is the superior origin of the pterygomandibular raphe, and the levator veli palatini muscle.

The pterygoid hamulus (PH) is a curved, small, and slender bony protrusion that arises from the base of the medial pterygoid plate of the sphenoid bone, extending downward and then turning laterally. Although its parts, i.e., base, body, neck, and head, are described in anatomical texts, they cannot be distinguished with the naked eye [ 1 , 2 ].

The pterygoid hamulus is a slender bony extension located at the lower end of the medial pterygoid plate's posterior border. It curves outward, featuring a groove for the tensor veli palatini muscle’s tendon.

2024年1月18日 · Each pterygoid process projects inferiorly from the junction of the body and greater wing of the sphenoid bone and bifurcates into a medial pterygoid plate and a lateral pterygoid plate. At the inferior tip of the medial pterygoid plate is the small hook-shaped process, the pterygoid hamulus.

2025年1月17日 · The pterygoid hamulus is a small, hook-like structure located within the pterygoid process of the sphenoid bone. It is a prominent feature of the human skull and plays a vital role in several important functions of the head and neck.

Pterygoid hamular bursitis is a rare craniofacial pain syndrome used to describe palatal and pharyngeal pain due to an enlarged pterygoid hamulus. The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each …

2014年6月19日 · Pterygoid hamulus syndrome is rare, with approximately 40 cases reported to date. Symptoms are thought to be caused by underlying bursitis or osteophytes. Key Imaging Features: History of pain that correlates with palpable hamuli on examination and erythema and keratinization of the overlying soft tissue.

2021年1月1日 · We report a rare case of pterygoid hamulus elongation with persistent sharp localized pain in the hamular region radiating to the temporal area for four years that was treated successfully by surgical resection of elongated hamulus.
