Anterior Labial Commissure Infections

The anterior labial commissure refers to the front corners of the mouth. An infection in this area involves the inflammation? or infection of the skin, mucous membranes, or underlying tissues, often caused by bacteria, viruses, or fungi.

Pathophysiology

Structure

The anterior labial commissure comprises:

• Skin: Thin and delicate, similar to facial skin.
• Mucosa: Lining of the mouth extending to the commissure.
• Muscles: Orbicularis oris muscle encircles the mouth.
• Tissues: Connective tissues providing support and flexibility.

Blood Supply

• Arteries?: Primarily supplied by the superior labial artery? (branch of the facial artery) and the angular artery.
• Veins?: Drain into the facial vein? system.

Nerve Supply

• Sensory: Innervated by branches of the infraorbital nerve and the mental nerve.
• Motor: Controlled by the facial nerve (cranial nerve VII) via the orbicularis oris muscle.

Types of Anterior Labial Commissure Infections

1. Bacterial? Infections: e.g., angular cheilitis caused by Staphylococcus aureus or Candida albicans.
2. Viral? Infections: e.g., Herpes simplex virus causing cold sores.
3. Fungal? Infections: Primarily Candida species.
