Trismus, often called lockjaw, is a condition where you have difficulty opening your mouth fully. This limitation in mouth opening is due to stiffness or spasms in the jaw muscles. While initially associated with tetanus, trismus now refers to any cause of restricted jaw movement.
Understanding Trismus
Trismus is characterized by a reduced range of motion in the jaw. A person with trismus can typically only open their mouth less than 35 millimeters. This can significantly impact daily activities such as eating, speaking, and oral hygiene.
The causes of trismus are varied, including:
- Trauma: Injuries to the jaw or surrounding muscles.
- Infections: Infections near the jaw, such as dental abscesses.
- Tetanus: A bacterial infection causing severe muscle spasms.
- Other medical conditions: Conditions impacting the temporomandibular joint (TMJ), such as arthritis.
- Medication side effects: Some medications can cause muscle stiffness as a side effect.
Symptoms of Trismus
The primary symptom is the inability to open the mouth fully. Other symptoms may include:
- Jaw pain
- Stiffness in the jaw muscles
- Difficulty chewing or swallowing
- Speech impairment
Treatment for Trismus
Treatment depends entirely on the underlying cause. Options may include:
- Medication: Pain relievers, muscle relaxants, or antibiotics (if an infection is present).
- Physical therapy: Exercises to improve jaw mobility.
- Surgery: In cases of severe injury or infection.
Trismus in Children
Trismus in children requires careful evaluation to determine the underlying cause and appropriate treatment, ensuring their comfort and health.
