What is coronoid process of mandible?

The coronoid process is a bony projection on the ramus of the mandible that serves as the attachment site for the temporalis muscle. It is located on the anterior and superior aspect of the mandibular ramus, just in front of the mandibular condyle.

The coronoid process is a slender, triangular-shaped structure that varies in size and shape among individuals. It is covered in a layer of dense cortical bone and is rich in blood vessels and nerve endings.

The primary function of the coronoid process is to provide leverage for the temporalis muscle during mastication (chewing). When the temporalis muscle contracts, it pulls the coronoid process upward and forward, allowing the jaw to close and the teeth to come together for biting and grinding food.

Fractures of the coronoid process can occur due to direct trauma to the jaw, such as in motor vehicle accidents or falls. These fractures can result in difficulty in opening the mouth, pain, swelling, and tenderness in the affected area. Treatment for coronoid process fractures often involves surgical repair to restore normal function and prevent further complications.
