Zygomatic bone surgery?


Hello Doctor, ten years ago I was in a car accident that resulted in fractures of my zygomatic bone and orbital bone.
After surgery, titanium metal was placed in my zygomatic bone, and the nerve part healed on its own after six months.
In recent years, I have experienced some tingling sensations in the surgical area when the weather changes, but it only lasts for a day or two.
This June, the surgical site on my left face suddenly became numb, similar to what I experienced after the accident.
I have no sensation in my face.
After undergoing a CT scan at the original surgical hospital, the facial bones and metal implants were found to be normal.
The doctor concluded that after ten years, it is unlikely to be related to metal rejection.
I then consulted with neurosurgery and neurology, and I was prescribed medications for nerve repair.
While I do not experience sharp pain or tingling on the surface of my face, I do feel numbness in my left canine teeth when I sleep on my left side.
The dentist also confirmed that it is not related to my teeth.
I would like to ask which specialty I should consult for further examination.
Should I see an orthopedic surgeon or an oral surgeon? Both neurology and neurosurgery have stated that my facial expressions are symmetrical and there are no further tests they can perform.
I have already consulted various specialties and am now seeking help from a family medicine doctor online.
I apologize for the disturbance and thank you for your assistance.
Could you please help me assess which additional examinations I might consider? Thank you.

Dear Mr.
Yao:
1.
Based on the symptoms you described, it may be indicative of the distribution of the trigeminal nerve; its branches innervate the gums and the roots of the teeth.
Any changes affecting the nerve distribution could lead to sensations of numbness or pain.
2.
Of course, if the corresponding vascular supply is compressed or inflamed, similar symptoms may also occur.
3.
Your symptoms could be a consequence of the surgery performed ten years ago, or they may be due to newly emerging causes (such as gum inflammation, peripheral infections, immune responses, etc.).
4.
I personally recommend that you maintain good oral hygiene, brushing your teeth after each meal if possible, and using dental floss or interdental brushes for cleaning.
If there is no improvement after a few days, you may consider seeking assistance from a dentist or a neurologist.
(The above is purely personal advice and for reference only.)

More Info


Understanding facial numbness after cheekbone surgery can be quite complex, especially given your history of trauma and surgical intervention. It’s important to recognize that the facial nerves are intricate and can be affected by various factors, including previous injuries, surgical procedures, and even the placement of hardware like titanium plates.

From your description, it seems that you experienced a significant injury to your cheekbone and eye socket, which required surgical repair. The fact that you had a period of numbness that resolved on its own after six months is a positive sign, indicating that some nerve regeneration occurred. However, the recent resurgence of numbness and loss of sensation in the same area is concerning and warrants further investigation.

Given that imaging studies (like CT scans) have shown no abnormalities in the bone or metal implants, and that specialists in neurology and neurosurgery have not found any significant issues, it may be beneficial to consider a few additional avenues:
1. Oral and Maxillofacial Surgery: Since your symptoms are localized to the facial region, consulting with an oral and maxillofacial surgeon could provide insights. These specialists are trained to handle complex facial structures and may offer a different perspective on the nerve function and any potential issues related to the surgical site.

2. Pain Management Specialist: If the numbness is associated with discomfort or pain, a pain management specialist could help. They may offer treatments such as nerve blocks or other interventions that could alleviate symptoms.

3. Physical Therapy: Engaging in physical therapy focused on facial rehabilitation may help improve nerve function and reduce symptoms. A therapist can work with you on exercises that stimulate the facial muscles and nerves, potentially aiding in recovery.

4. Electromyography (EMG) and Nerve Conduction Studies: If not already done, these tests can evaluate the electrical activity of your muscles and the speed of nerve conduction. They can help identify any nerve damage or dysfunction that may not be visible on imaging studies.

5. Psychological Evaluation: Sometimes, chronic pain or numbness can be exacerbated by psychological factors. Consulting with a psychologist or psychiatrist may provide support and coping strategies, especially if you are experiencing anxiety related to your symptoms.

6. Follow-Up with Your Primary Care Physician: Since you mentioned seeking advice from a family medicine doctor, they can coordinate your care and help you navigate referrals to the appropriate specialists based on your evolving symptoms.

In terms of your specific symptoms, the transient nature of the numbness you experienced could suggest that there are still some nerve pathways that are recovering. The fact that pressure on the left side of your face affects your teeth could indicate that the trigeminal nerve, which supplies sensation to the face and teeth, might be involved.
It’s essential to keep a detailed record of your symptoms, including when they occur, their duration, and any potential triggers. This information can be invaluable for your healthcare providers in diagnosing and managing your condition.

In conclusion, while it can be frustrating to navigate through various specialists without a clear answer, persistence is key. Continue to advocate for yourself and seek out the appropriate specialists who can help you understand and manage your symptoms effectively. Your health and well-being are paramount, and with the right approach, there is hope for improvement in your condition.
