Exploring Nerve or Muscle Damage After Orthognathic Surgery: A Case Study - Neurology

More Info

---

After orthognathic surgery, patients may experience a range of complications, including nerve or muscle damage. In your case, the symptoms you describe—such as pain behind the eye, eye fatigue, and visual disturbances—could indeed be related to nerve or muscle issues, particularly if they have persisted for three years without improvement.


Understanding the Symptoms
The symptoms you are experiencing could potentially be linked to several factors:
1. Nerve Damage: During orthognathic surgery, the surgical manipulation of the jaw and surrounding structures can inadvertently affect nearby nerves. The trigeminal nerve, which is responsible for sensation in the face, can be particularly vulnerable. If this nerve is damaged, it can lead to sensations of pain, tingling, or numbness in the facial region, including around the eyes.

2. Muscle Damage or Dysfunction: The muscles involved in jaw movement may also be affected during surgery. If these muscles are not functioning properly, it could lead to discomfort or pain, especially if they are overcompensating for weakness or dysfunction elsewhere.

3. Titanium Plates and Screws: The presence of titanium plates and screws used for stabilization can sometimes lead to discomfort or irritation, especially if they are positioned close to sensitive areas such as the nasal cavity or the eyes. While titanium is generally biocompatible, individual reactions can vary, and in some cases, the hardware may need to be removed if it is causing significant issues.


Diagnostic Considerations
Given that MRI and CT scans have not revealed any abnormalities, it is essential to consider other diagnostic avenues:
- Electromyography (EMG) and Nerve Conduction Studies (NCS): These tests can help assess the function of the nerves and muscles in the affected area. They can identify any nerve damage that may not be visible on imaging studies.

- Consultation with Specialists: It may be beneficial to consult with a neurologist or a pain specialist who can provide insights into your symptoms and recommend further testing or treatment options.


Treatment Options
1. Pain Management: Since muscle relaxants and pain medications have not been effective, you might want to explore other pain management strategies. This could include physical therapy, acupuncture, or alternative therapies such as biofeedback.

2. Nerve Blocks: If nerve damage is suspected, a nerve block may provide temporary relief and help confirm the diagnosis. This involves injecting anesthetic near the affected nerve to see if it alleviates pain.

3. Surgical Intervention: In cases where hardware is suspected to be the source of pain, a surgical consultation may be warranted to discuss the possibility of removing or adjusting the titanium plates or screws.

4. Rehabilitation: Engaging in a structured rehabilitation program focusing on jaw and facial muscle exercises may help improve function and reduce discomfort.


Prognosis
The prognosis for recovery from nerve or muscle damage varies widely depending on the extent of the injury and the individual’s overall health. Some patients may experience gradual improvement over time, while others may have persistent symptoms. Early intervention and a multidisciplinary approach to treatment can significantly enhance recovery outcomes.


Conclusion
In summary, your ongoing symptoms after orthognathic surgery could indeed be related to nerve or muscle damage, possibly exacerbated by the surgical hardware. A comprehensive evaluation by specialists, including neurologists and pain management experts, is crucial for developing an effective treatment plan. Exploring various therapeutic options and maintaining open communication with your healthcare providers will be key to managing your symptoms and improving your quality of life.
