Sinusitis is an inflammation of the sinus mucosa. The sinuses are cavities near to the nose inside the skull bones. As the sinuses are linked to the nasal cavity, sinusitis often results from complications of ordinary pathologies such as:Man with sinus pain

  • Colds
  • Allergic rhinitis
  • Bacterial diseases

It is characterised by various symptoms such as:

  • Facial or dental pain
  • Nasal congestion
  • Nasal secretions
  • Loss of smell
  • High temperature

Sinusitis is a common disorder, the prevalence of which is however difficult to estimate. According to certain studies, it affects 10 % to 15 % of the population, adults and children alike.



Often of viral origin, it generally follows on from a cold which is complicated by a sinus infection. . It usually lasts less than 4 weeks and occurs less than 3 times per year. It can also be caused by bacterial or fungal infection, by an allergy, atmospheric pollution of by a dental abscess which has spread to the sinuses.


Sinusitis becomes chronic when it lasts more than 12 weeks. Its is often of allergic origin: 50 to 80% of people with chronic sinusitis have allergic rhinitis. It may also be the result of acute sinusitis incorrectly treated or be related to a deviation in the natural septum, to smoking or to immune deficiency.

Daily nasal hygiene with isotonic spray like Humer Daily Hygiene prevents sinusitis by removing mucosities and contaminant agents to prevent the appearance of inflammatory mediators.
Irrigation with hypertonic spray like Humer Blocked Nose allow to decongest and clean the sinuses, making removal of pathogenic mucus easier.
