Mucosal inflammation in the sinuses

What is it?

Sinus inflammation, often called sinusitis, is an acute infection of the mucous in the nasal sinuses. The inflammation is usually caused by a virus and is similar to a common cold. There are two types of sinusitis: acute sinusitus and chronic sinusitis.

Sinuses are air-filled cavities in the cranium, next to and above the nose, the eyes, the upper jaw and the forehead. The swelling of the mucousal membranes makes it difficult to empty the mucous, (secretions) and it collects in the sinuses. In some cases, there can be an additional bacterial infection.

In young children, these sinuses are not yet fully developed and so they rarely have this condition.

Symptoms

Acute sinusitis

• nasal congestion
• yellow/green mucus at the front and back of the nose that may run down to the throat (postnasal drip), sometimes resulting in coughing
• reduced sense of smell (and possibly of taste)
• feeling of pressure in the face, along the upper teeth

These are the most common symptoms of acute sinusitis and they usually improve after a few weeks.

Chronic sinusitis

• a sinus infection that lasts for twelve weeks or longer

In addition, the other symptoms present are similar to the symptoms of an acute infection, only that they last a lot longer and keep coming back.

Diagnosis

Acute sinusitis

Your physician can make the diagnosis based on your symptoms and clinical examination in the nose with a nasal endoscopy. Medical imaging is not indicated for an acute infection, unless complications arise. In rare cases, the infection can spread to the nearby eye socket or to the brain.

Chronic sinusitis

The physician makes the diagnosis based on medical history (your medical history, current health...), clinical examination with a nasal endoscopy and a CT scan of the sinuses. In healthy sinuses, there is air (which appears black on the scan) in the sinuses. If the sinuses are infected, this area appears gray on the scan.

Treatment

Acute sinusitis

In most cases, the sinusitis resolves on its own, just like a common cold. Pain medication, nasal sprays, and nasal rinses can alleviate symptoms. In case of a bacterial infection, your physician may start treatment with antibiotics.

Chronic sinusitis

For mild symptoms, a corticosteroid nasal spray with nasal rinses can be sufficient. For severe symptoms, a long-term course of antibiotics may be considered, whether or not combined with a short course of cortisone pills. In addition, a procedure may be performed in order to widen the sinus drainage passages. This is called a functional endoscopic sinus surgery (FESS).
