Why is there still pain after sinus surgery?


Hello, doctor.
My husband underwent endoscopic sinus surgery for acute sinusitis at the beginning of March due to headaches.
After being discharged and resting at home, he only experienced slight nasal congestion and mild soreness at the tip of his nose.
However, about two weeks post-discharge, he began to feel soreness above his eyebrows on his forehead, which then radiated to his head and even to his gums, where he experienced sharp pain (the painful areas are different from where he felt pain during the acute sinusitis).
When we returned to the hospital for a check-up, the surgical site was healing well, with no signs of bleeding, swelling, or infection.
The doctor mentioned that this is a type of neuropathic pain.
Our family is very concerned, fearing that the surgery may have damaged a nerve, but the doctor assured us that this type of neuropathic pain can be treated and requires gradual medication adjustments.
I would like to ask if sinus surgery truly does not damage nerves, and if this type of postoperative neuropathic pain is normal.

Post-sinus surgery pain, particularly following endoscopic sinus surgery, can indeed be a source of concern for patients and their families. Your description of the symptoms—pain radiating from the forehead to the teeth, and the sensation of aching in the areas surrounding the surgery site—raises valid questions about the possibility of nerve damage and the nature of post-operative pain.

Firstly, it is important to understand that while endoscopic sinus surgery is generally considered a minimally invasive procedure, it does involve manipulation of the nasal and sinus structures, which are in close proximity to various nerves. The most notable among these is the trigeminal nerve, which is responsible for sensation in the face. Although the risk of direct nerve injury during the procedure is low, it is not entirely absent. In some cases, the surgical manipulation can lead to temporary irritation or inflammation of the nerves, which may manifest as pain or discomfort in areas that are not directly related to the surgical site.

The symptoms you describe, particularly the pain that has developed weeks after surgery, may be indicative of a condition known as neuropathic pain. This type of pain arises from damage or dysfunction in the nervous system and can occur even in the absence of direct nerve injury. It is characterized by sensations such as burning, tingling, or sharp pain, and can sometimes be triggered by stimuli that would not normally cause pain. The fact that your pain is radiating to different areas, such as the teeth, suggests that it may be related to nerve pathways rather than a localized issue at the surgical site.

From a medical standpoint, it is reassuring to hear that your follow-up examination showed no signs of infection or complications at the surgical site. This is a positive indicator that the healing process is proceeding as expected. However, the presence of ongoing pain can be distressing and may require further management. Your doctor’s suggestion that this type of nerve pain can be treated is accurate; there are various approaches to managing neuropathic pain, including medications such as anticonvulsants (like gabapentin or pregabalin) and antidepressants (like amitriptyline), which can help modulate nerve pain signals.

In terms of the timeline for recovery, nerve-related pain can sometimes take weeks to months to resolve, as the nervous system can take time to heal and adjust after surgical trauma. It is essential to maintain open communication with your healthcare provider regarding your symptoms. If the pain persists or worsens, further evaluation may be warranted to rule out any underlying issues that could be contributing to your discomfort.

In conclusion, while the risk of nerve damage during sinus surgery is low, the occurrence of post-operative nerve pain is a recognized phenomenon. It is crucial to manage this pain effectively and to monitor your symptoms closely. If you have concerns about the nature of your pain or its persistence, do not hesitate to seek further medical advice. Your healthcare provider can help tailor a treatment plan that addresses your specific needs and supports your recovery.
