Surgery of paranasal sinuses is usually performed to treat prolonged inflammations. Symptoms of sinusitis are e.g. stuffy nose, discharge of phlegm, headache, and weakening of the sense of smell. Nasal polyps may also be a reason for the operation. These are benign growths of the mucous membranes of the nose. They may block up the nose leading to chronic inflammations.


The procedure is usually performed under local anaesthesia. The narrow nasal sinuses are widened using an endoscope, so that the airflow to the paranasal sinuses is improved. Often a part of the bony structure and unhealthy mucous membrane must be removed to ensure a good result.


At the final stage of the operation, so called nasal tampons are inserted into the nose to prevent bleeding. They are usually removed on the next day at the Ear Outpatient Clinic. In some cases, the tampons are left for a week and removed on the first follow-up visit, when the nose is cleaned and the paranasal sinuses are rinsed.

Your nose may feel stuffy for the first week due to swelling of the mucous membrane and dried discharge. It is important that you moisten your nose carefully with saline solution for one week after the procedure. Avoid blowing your nose. Also, avoid physical effort and sauna for the first week.

Treatment of pain

The nasal area may feel sore, but severe pain occurs rarely. Usually, non-prescription painkillers are sufficient.


If you experience bleeding, fever exceeding 38 ºC (=100ºF), or other symptoms of inflammation, contact the hospital.
