The coronoid process is a triangular, anteriorly projecting bony eminence located at the anterior border of the mandibular ramus. It serves as the insertion site for the temporalis muscle, a primary muscle of mastication responsible for elevating the mandible. The coronoid process is thin and sharp, and its shape can vary among individuals. Its anterior surface is concave and smooth, while the posterior surface is convex and roughened by muscular attachments. The medial surface features a prominent ridge known as the coronoid crest, which also anchors the temporalis muscle.

The coronoid process is an important anatomical landmark in dentistry and oral surgery. Its position and relationship to the mandibular notch and the sigmoid notch are crucial for understanding mandibular mechanics and surgical approaches. Fractures involving the coronoid process are relatively uncommon but can occur in conjunction with other mandibular fractures. In some cases, the coronoid process can become hypertrophied, leading to a condition known as coronoid hyperplasia, which can restrict mouth opening and interfere with mastication. Surgical intervention may be necessary to address significant hypertrophic elongation or entrapment of the coronoid process.
