The pterygoid hamulus: description of its anatomy, topography and clinical implications - a review of literature.

The pterygoid hamulus is a bony process that protrudes from the medial pterygoid plate of the sphenoid bone. In spite of its small size and fragile structure, the pterygoid hamulus is an important anatomical structure in many clinical aspects. Orofacial pain may be related to inflammation or irritation of the pterygoid hamulus; if not, other possible explanations should be explored. In addition, the pterygoid hamulus is an important landmark in the oral cavity and is utilized in a number of dental and medical procedures. Thus, the purpose of this work was to review recent studies demonstrating the role and significance of the pterygoid hamulus in clinical practice.
