Mandibular notch

Mandibular Notch

The Mandibular Notch is a significant anatomical structure in the human skull. It is located on the upper border of the lower jaw, also known as the mandible. The mandibular notch is a deep concave structure that separates the two condylar processes of the mandible.

Anatomy

The mandibular notch is located between the coronoid process and the condylar process. These two processes are posterior extensions of the mandible that serve different functions. The coronoid process is the point of attachment for the temporalis muscle, which is involved in closing the jaw. The condylar process forms part of the temporomandibular joint, which allows for movement of the jaw.

The mandibular notch is a significant landmark in oral and maxillofacial surgery. It is often used as a reference point in procedures involving the mandible.

Clinical Significance

The mandibular notch can be involved in various medical conditions and procedures. For instance, it can be affected in cases of mandibular fracture, where the fracture line can extend into the notch. It is also a critical landmark in surgical procedures involving the mandible, such as mandibular osteotomy.
