Mylohyoid Nerve: Anatomy, Functions and Diseases

The maxillohyoid nerve (n. mylohyoideus) is a nerve that provides sensitivity and motor functions to the muscles located in the area of ​​the lower jaw and hyoid bone. It is one of the most important nerves of the head and neck.

Anatomy of the Mylohyoid nerve

The Mylohyoid nerve passes through the deep salivary gland and then branches into two branches: inferior and superior. The superior branch provides sensation to the palate and posterior part of the maxilla, and the inferior branch innervates the muscles associated with the hyoid bone and mandible.

Functions of the maxillohyoid nerve

The mylohyoid nerve plays an important role in speech, chewing and swallowing. It provides motor functions to the muscles that elevate and stabilize the hyoid bone, as well as the muscles associated with chewing and swallowing. In addition, the Mylohyoid nerve innervates the lower dentition, providing sensitivity to this area.

Diseases of the maxillohyoid nerve

The Mylohyoid nerve can be affected by various diseases such as neuralgia, neuroma, trauma or infection. Mylohyoid neuralgia manifests as acute pain in the hyoid bone, which may worsen with speaking, chewing, or swallowing. A neuroma is a tumor that can develop on a nerve and cause pain and sensory disturbances. Trauma or infection can also damage the Mylohyoid nerve and impair its function.

In conclusion, the Mylohyoid nerve plays an important role in the functioning of the mandible and hyoid bone. It provides sensation and motor functions in this area. Various diseases can affect the nerve and cause pain, sensory disturbances, or movement problems. If you have symptoms related to the Mylohyoid nerve, see your doctor for diagnosis and treatment.
