Condylar fracture with mandibular deviation upon opening the mouth?
Hello, doctor.
I had a car accident over two years ago that resulted in a left condylar fracture.
After undergoing intraoral surgery, I still have a deviation (subluxation).
I am currently using an occlusal splint for opening exercises, but when I open my mouth 3 cm, my mandible deviates to the left by about half a tooth, and when I open it 3.5 cm, the deviation increases to about one tooth.
The larger I open my mouth, the greater the deviation to the left.
(When my mouth is closed, there is no deviation; occlusion is normal.) I would like to ask if this deviation during mouth opening can be improved with rehabilitation.
Thank you very much for your response.

Dear Anonymous Miss: Hello! As mentioned, it is acceptable for the mandible to deviate when opening the mouth due to muscle traction after a condylar fracture, as long as the occlusion is normal, it should not affect the quality of life.
Rehabilitation can improve the condition, depending on the severity of the injury.
Please communicate more with your physician! Thank you! Wishing you safety! Sincerely, Dr.
Huang Ting-Fang, Dentistry.

More Info
Improving jaw deviation after a condylar fracture can be a challenging process, but with the right rehabilitation strategies, significant progress can be made. It’s essential to understand the mechanics of jaw movement and the implications of your specific injury.
After a condylar fracture, the alignment of the jaw can be affected due to the displacement of the fractured bone, which can lead to deviations during opening and closing of the mouth. In your case, the left deviation during mouth opening indicates that the fractured condyle may not be healing in the correct position, or there may be soft tissue restrictions that are contributing to the deviation.
Rehabilitation Strategies
1. Physical Therapy: Engaging with a physical therapist who specializes in orofacial rehabilitation is crucial. They can provide targeted exercises to improve the range of motion and strength of the jaw muscles. These exercises may include:
- Jaw Stretching Exercises: Gradually increasing the range of motion by performing controlled opening and closing movements. This can help in reducing the deviation over time.
- Resistance Exercises: Using resistance bands or your own hand to provide resistance while opening and closing your mouth can strengthen the muscles involved in jaw movement.
2. Use of a Splint or Occlusal Device: You mentioned using a bite plate for opening exercises. This can help in stabilizing the jaw and promoting proper alignment during movement. It’s important to ensure that the splint is correctly fitted and adjusted as needed by your dentist or orthodontist.
3. Manual Therapy: Techniques such as myofascial release or joint mobilization performed by a trained therapist can help alleviate tension in the surrounding muscles and improve joint function.
4. Home Exercises: Consistency is key in rehabilitation. Performing daily exercises at home, as prescribed by your therapist, can significantly enhance your recovery. This may include gentle stretching and controlled movements to encourage proper alignment.
5. Monitoring Progress: Keeping track of your progress is essential. Documenting the degree of deviation during opening and any changes in pain or discomfort can help your healthcare provider adjust your rehabilitation plan accordingly.
Potential Outcomes
While improvement is possible, the extent of recovery can vary based on several factors, including the severity of the fracture, the timing of intervention, and adherence to rehabilitation protocols. In many cases, with diligent effort, patients can achieve a more symmetrical jaw opening and improved function.
Concerns About Long-Term Effects
You may wonder about the long-term implications of your current condition. If left unaddressed, deviations can lead to further complications, such as:
- TMJ Disorders: Chronic pain or dysfunction in the temporomandibular joint.
- Dental Issues: Misalignment can lead to uneven wear on teeth or bite problems.
- Muscle Strain: Ongoing asymmetry can cause strain on the muscles of mastication, leading to discomfort.
Conclusion
In summary, addressing jaw deviation after a condylar fracture requires a comprehensive rehabilitation approach that includes physical therapy, the use of splints, and consistent home exercises. Collaborating closely with your healthcare team will ensure that you receive tailored interventions that can lead to improved jaw function and alignment. Remember to communicate openly with your therapist about your progress and any concerns you may have, as this will help in optimizing your rehabilitation journey.
