Trismus
Trismus is a medical condition characterized by the inability to open the mouth fully due to a reduced range of motion in the jaw joint. This condition can be caused by a variety of factors, including trauma, infection, and certain medical treatments.
Causes[edit | edit source]
Trismus can be caused by a variety of factors. These include:
- Trauma: This can include physical injury to the jaw or surrounding tissues, or damage caused by surgical procedures.
- Infection: Infections in the mouth or throat, such as tonsillitis or peritonsillar abscess, can cause trismus.
- Medical treatments: Certain medical treatments, such as radiation therapy for head and neck cancers, can cause trismus as a side effect.
Symptoms[edit | edit source]
The primary symptom of trismus is the inability to open the mouth fully. This can make it difficult to eat, speak, or maintain oral hygiene. Other symptoms can include:
- Pain in the jaw or surrounding muscles
- Difficulty swallowing
- Changes in speech
Treatment[edit | edit source]
Treatment for trismus depends on the underlying cause. This can include:
- Physical therapy: This can help to improve the range of motion in the jaw.
- Medication: Pain relievers and muscle relaxants can help to alleviate symptoms.
- Surgery: In severe cases, surgery may be necessary to correct the problem.
