Mandibular Tenderloin

The mandibular notch, also known as incisura mandibulae, pna, bna or jna, is an important anatomical feature of the mandible. This depression is located on the inner surface of the lower jaw, where it connects to the temporal bone through the temporomandibular joint.

The notch of the lower jaw has the shape of a semicircular cavity and serves to accommodate the mandibular teeth and roots. It is also the attachment point for the muscles that are involved in the chewing process.

Due to its location and shape, the mandibular notch can be involved in various pathological processes, such as arthrosis of the temporomandibular joint, tumor processes or trauma. In some cases, surgical removal of part of the lower jaw, including the notch, may be required, for example, in case of tumor diseases.

Surgical removal of the mandibular notch may also be necessary in cases where the shape of the jaw does not allow the placement of dentures or implants. However, this process may require additional precautions and careful planning to avoid damage to the nerves and other important structures that pass through the mandible.

Overall, the mandibular notch is an important anatomical element that plays a role in maintaining the structure of the jaw and the functioning of the masticatory system. However, in some cases, surgical removal of this area may be necessary to treat certain conditions.
