Anterior Labial Commissure Spasms

Anterior labial commissure spasms refer to involuntary muscle contractions at the front corners of the mouth, known as the labial commissures. These spasms can cause twitching, tightening, or even pain around the mouth area. While muscle spasms can occur anywhere in the body, spasms at the anterior labial commissure specifically affect the muscles around the mouth’s front corners.

Pathophysiology

Understanding the pathophysiology—how the body functions when affected by a disease or condition—helps in grasping why anterior labial commissure spasms occur.

Structure

The anterior labial commissure is the corner where the upper and lower lips meet at the front of the mouth. It involves several small muscles, including:

• Orbicularis Oris: Encircles the mouth, controlling movements like puckering.
• Buccinator: Located in the cheek, helps in chewing and blowing.

Blood Supply

The area receives blood primarily through:

• Superior Labial Artery: Supplies the upper lip and commissure.
• Inferior Labial Artery: Supplies the lower lip and commissure.

Adequate blood flow is essential for muscle health and function.

Nerve Supply

Nerve signals control muscle contractions. The main nerves involved are:

• Facial Nerve (Cranial Nerve VII): Controls muscles of facial expression, including those at the labial commissure.
• Trigeminal Nerve (Cranial Nerve V): Provides sensory information and some motor functions to the face.

Disruptions in these nerves can lead to abnormal muscle activity, resulting in spasms.
