Sinusitis is a common condition that affects many people - especially during the cold season. It can be acute or chronic and is sometimes accompanied by severe symptoms.

Here you will find further information on the symptoms, diagnosis and treatment options well as selected doctors for the treatment of sinusitis.

ICD codes for this diseases: J01, J32

Brief overview:

  • What is sinusitis? An inflammation of the sinus mucosa. It can be acute or chronic (lasting longer than 12 weeks).
  • Causes: Viruses, bacteria or fungi usually cause the inflammatory reaction in the accesses to the paranasal sinuses.
  • Symptoms: Different headaches occur depending on the sinus cavity affected. They can be localized behind the eyes, on the forehead or at the back of the head.
  • Diagnosis: A medical history and physical examination are sufficient for the diagnosis; if chronic inflammation is suspected, a CT scan is often used.
  • Treatment: The acute form is usually treated conservatively, for example with nasal drops and high insoles. The chronic form requires further medication and possibly surgery to widen the accesses.

Article overview

What is sinusitis?

Sinusitis is an inflammation of the mucous membranes in the paranasal sinuses - the air-filled cavities in the skull bone that are connected to the nasal cavity.

Doctors distinguish between two forms of sinusitis:

  • Acute sinusitis: This usually develops after a cold and usually lasts less than 12 weeks.
  • Chronic sinusitis: If the symptoms persist for longer than 12 weeks, it is referred to as a chronic form. It can be permanent or recurrent.

For those affected, the disease often means a severe reduction in quality of life due to a blocked nose, headaches and a general feeling of illness.

Typical symptoms of sinusitis

The symptoms vary depending on the location of the affected sinus. Common symptoms are

  • Stuffy or runny nose
  • Feeling of pressure in the face, especially in the forehead, eyes and cheeks
  • Headache, which can worsen when bending down
  • Reduced sense of smell
  • Tiredness and fatigue
  • Purulent nasal discharge
  • Fever (in the case of bacterial infections)

Note: If several paranasal sinuses are inflamed at the same time, this is referred to as pansinusitis.

Causes and risk factors

Acute sinusitis usually occurs as a result of a viral infection of the upper respiratory tract, i.e. a common cold. This causes the mucous membranes to swell and the mucus can no longer drain properly - an ideal breeding ground for bacteria.

Possible pathogens are

  • Viruses (e.g. colds)
  • Bacteria (often due to superinfection)
  • Less frequently: fungi

Risk factors for the development of sinusitis include

How is sinusitis diagnosed?

The diagnosis begins with a detailed medical consultation (medical history) and an examination of the nose. The following examination methods are used

  • Endoscopy of the nose: view into the nasal cavity with a small camera
  • Ultrasound (especially in children)
  • Computed tomography (CT): important for chronic sinusitis or before an operation
  • Allergy tests: if allergic involvement is suspected
  • Smear test: if bacterial infection is suspected

Treatment of sinusitis

The therapy depends on the course of the disease (acute or chronic) and the underlying trigger.

Acute sinusitis - therapy:

In most cases, acute sinusitis heals without special treatment. Supportive effect:

  • Decongestant nasal sprays (no longer than 7 days)
  • Inhalations with saline solution
  • Drink plenty of fluids to liquefy the mucus
  • Painkillers if required
  • Moist heat (e.g. steam baths, nasal showers)

The use of antibiotics may only be necessary in the case of a bacterial infection.

Chronic sinusitis - therapy:

In the chronic form, structural or inflammatory changes are usually responsible. Treatment options are:

  • Nasal sprays or tablets containing cortisone
  • Allergy treatment if an allergy is involved
  • Surgery (e.g. endoscopic sinus surgery) for severe symptoms or anatomical constrictions

The aim of sinus surgery is to improve ventilation and drainage of the sinuses.

Progression and prognosis

Acute sinusitis usually heals without consequences within 1 to 2 weeks. It is important to cure it consistently in order to prevent it from spreading to neighboring structures (e.g. eyes, brain).

Chronic sinusitis can severely restrict quality of life. However, with the right treatment - medication or surgery - it is usually possible to control the symptoms well.

Frequently asked questions about sinusitis

Is sinusitis contagious?

Not directly. The underlying viral infection is transmissible via droplets - sinusitis itself is not.

When should you see a doctor?

  • If the symptoms last longer than 10 days
  • In the event of a high temperature
  • In the event of severe pain in the face or head
  • If the symptoms suddenly worsen after an interim improvement

Which specialists are responsible?

An ENT doctor (ear, nose and throat specialist) is the right person to contact for diagnosis and treatment.

Fazit

Sinusitis is a common and often unpleasant condition. While the acute form is usually harmless, chronic sinusitis can be persistent. With early diagnosis and the right treatment, complications can be avoided and symptoms significantly alleviated.
