Posterior labial commissure hypertrophy refers to the abnormal enlargement or thickening of the back corners of the mouth where the upper and lower lips meet, known as the posterior labial commissures. This condition can affect appearance, speech, and oral functions.
Pathophysiology
Understanding the underlying mechanisms of posterior labial commissure hypertrophy involves looking at the structure, blood supply, and nerve supply of the affected area.
Structure
The posterior labial commissure is the junction where the upper and lower lips meet toward the back of the mouth. Hypertrophy in this area means that the tissues—skin, muscle, or connective tissue—have become enlarged.
Blood Supply
The blood supply to the posterior labial commissure comes primarily from branches of the facial artery. Adequate blood flow is essential for tissue health and healing.
Nerve Supply
Nerves supplying this area include branches of the facial nerve (cranial nerve VII), which controls muscle movements of facial expressions, and sensory nerves that provide feeling to the lips and surrounding tissues.
Types of Posterior Labial Commissure Hypertrophy
While posterior labial commissure hypertrophy is generally categorized based on the underlying cause and the specific tissues involved, here are some common types:
- Muscular Hypertrophy: Enlargement of the muscle tissues around the commissure.
- Fibrous Hypertrophy: Thickening due to increased fibrous connective tissue.
- Fatty Hypertrophy: Accumulation of fat cells leading to enlargement.
- Mixed Hypertrophy: Combination of muscle, fibrous, and fat tissue enlargement.
Causes
Posterior labial commissure hypertrophy can result from various factors. Here are 20 possible causes:
- Genetic Predisposition: Family history of similar conditions.
