Full steam ahead into the paranasal sinuses – PARI SINUS in action

In an imaging study conducted with 15 healthy volunteers, Dr Moeller and his team succeeded in showing that the paranasal sinuses cannot be reached by inhalation from nasal sprays as opposed to inhalation with the PARI vibrating aerosol.

At the annual conference of the German Society for Pulmonology (DGP), Dr. Moeller from the HelmholtzZentrum münchen presented the most recent results of his work group on inhalation therapy with the PARI SINUS device and its further development, the PARI Vibrent^® device. The fact that the paranasal cavities were so efficiently reached with PARI SINUS and Vibrent^® could be attributed to the unique mechanism of operation of these special nebuliser devices, he stated. Only with the pulsation of the aerosol and a slight counter pressure in the second nostril could some of the healing steam penetrate to the site of action – the inflamed paranasal sinuses.

Dr. Moeller also reported on a medical case showing that this therapeutic principle can be extremely beneficial: A patient with persistent chronic sinusitis was already scheduled for surgery. However, aerosol therapy with a PARI SINUS device then resolved the inflammation and the associated symptoms, and surgical intervention was avoided.

According to Dr. Moeller, chronic sinusitis is a very common disorder. He stated that it is estimated that about 10-15% of the European and US population are affected by this disease.
