A novel device combining acoustic vibration with oscillating expiratory pressure for the treatment of nasal congestion.

Background: Chronic nasal congestion affects 20% of the population with significant impact on quality of life. This study investigated the simultaneous administration of nasal acoustic vibration and oscillating expiratory pressure for the treatment of nasal congestion.

Methods: Patients with chronic nasal congestion but without fixed anatomic obstruction participated in a prospective clinical study applying simultaneous acoustic vibrations and positive expiratory pressure to the nasal cavity twice daily over 5 weeks.
