Post-operative nasal irrigation issues following unilateral sinusitis surgery?


Hello, doctor.
I recently underwent surgery for unilateral sinusitis, and I need to start nasal irrigation postoperatively.
Currently, I am doing it once in the morning and once at night.
I would like to know if I also need to irrigate the side that did not have surgery.

Hello: Generally, it is necessary to rinse the surgical side, while the normal side does not need to be cleaned if there are no symptoms.
Wishing you peace and health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan General Hospital, Ministry of Health and Welfare.

After undergoing sinus surgery, particularly for unilateral sinusitis, it's essential to follow a proper post-operative care regimen to ensure optimal healing and prevent complications. Rinsing the nasal passages is a common recommendation after such procedures, as it helps to clear mucus, debris, and any potential pathogens from the nasal cavity.
In your case, since you have had surgery on one side, it is generally advisable to rinse both sides of your nasal passages. Here’s why:
1. Preventing Infection: Rinsing the unaffected side can help maintain overall nasal hygiene. Even though the surgery was performed on one side, bacteria or irritants can still affect the other side. Keeping both sides clean can help prevent infections that could complicate your recovery.

2. Promoting Drainage: Post-surgery, the nasal passages can be swollen or congested. Rinsing both sides can facilitate drainage and help maintain airflow, which is crucial for healing. It can also help reduce the risk of developing sinusitis on the unaffected side due to congestion.

3. Balancing Nasal Function: After surgery, the nasal passages may have altered airflow dynamics. Rinsing both sides can help ensure that both sides are functioning optimally, which can aid in overall nasal health and comfort.

4. Hydration of Mucous Membranes: Rinsing helps to keep the mucous membranes moist, which is essential for healing. This is particularly important after surgery, as the tissues may be more sensitive and prone to irritation.

When rinsing, it’s important to use a saline solution that is isotonic or slightly hypertonic to avoid irritation. You can use a saline nasal spray or a neti pot, ensuring that the water is sterile or distilled to prevent introducing any pathogens into your nasal passages.

In terms of frequency, continuing with your routine of rinsing twice a day is a good practice, but you may also want to consult your surgeon or healthcare provider for personalized advice based on your specific situation. They may suggest adjustments based on your healing progress or any symptoms you may be experiencing.

Lastly, if you notice any unusual symptoms such as increased pain, swelling, or discharge that is not clear or is accompanied by a foul odor, it’s crucial to contact your healthcare provider promptly. These could be signs of infection or other complications that may require further evaluation.

In summary, rinsing both sides of your nasal passages after unilateral sinus surgery is generally recommended to promote healing, prevent infection, and maintain overall nasal health. Always follow your surgeon's specific instructions and consult them if you have any concerns during your recovery.
