The working group on aerosol therapy (GAT) of the Société de Pneumologie de Langue Française (SPLF) has organized its third Aerosolstorming in 2012. During one single day, different aspects of inhaled therapies have been treated and are detailed in two articles, this one being the second. This text deals with the indications of inhaled corticosteroids in ENT, the development and technical challenges of powder inhalers, the advantages and disadvantages of each type of technologies to measure the particle sizes of inhaled treatments.
