Treatment with a corticosteroid nasal spray for chronic sinusitis reduces complaints such as nasal congestion, runny nose and loss of smell after twenty weeks of therapy. It also reduces the size of the polyp after sixteen weeks of therapy.
The guideline also recommends rinsing with isotonic saline solution, because this relieves the complaints. According to the guideline, systemic corticosteroids should be used as little as possible. There is little evidence for its effectiveness. In case of serious complaints despite other medication, doctors can use these drugs in certain cases, but preferably not more often than twice a year.
There is also little supporting evidence for the short-term and long-term use of antibiotics. The use of antibiotics is therefore not recommended. In the event of an acute exacerbation of an uncomplicated chronic sinus infection, a short-term antibiotic course of up to two weeks may be considered.
Monoclonal antibodies such as dupilumab and omaluzimab may be considered by practitioners for moderate or severe forms of nasal polyps if standard treatment has insufficient effect.
Chronic rhinosinusitis
With a sinus infection, the nasal mucosa is swollen, leading to nasal congestion. The swelling can cause mucus to accumulate in the cavities, which can cause complaints such as headaches above and below the eyes. Loss of smell may also occur.
Chronic sinusitis is also called chronic rhinosinusitis (CRS). This is the case when the complaints persist for more than twelve weeks in patients. These people have a higher risk of developing nasal polyps. These are benign swellings of the nasal mucosa, which hinder proper drainage from the cavities.
