G50-G59: Nerve, nerve root and plexus disorders
G50: Disorders of trigeminal nerve
Disorders of the trigeminal nerve, also known as the fifth cranial nerve, consist of a group of conditions that affect the nerve responsible for sensation in the face and motor functions such as biting and chewing. Common causes include pressure from blood vessels, nerve damage resulting from diseases like multiple sclerosis, or damage from surgical procedures or trauma. These disorders commonly present with symptoms such as acute facial pain, tingling or numbness, and difficulty with facial movements. The progression of these conditions varies greatly depending on the type of disorder, some may have episodic symptoms while others may have symptoms that worsen over time. These disorders can have significant impact on the patient's quality of life, affecting their ability to perform basic everyday tasks.
