SCONA 2019 will be held on Wednesday June 5th, 2019 in conjunction with Rhinoworld Chicago

Principal Sponsor:



Computational fluid dynamics (CFD) is emerging as a powerful objective tool in otolaryngology. CFD technology can quantify upper airway physiological functions, including airflow conductance, nasal air conditioning (heating and humidification of inspired air), delivery of odorant molecules to the olfactory epithelium, flow-induced phonation, and delivery of aerosol medications to their target sites. CFD has been applied to investigate the pathophysiology of a wide range of upper airway diseases, including nasal airway obstruction, chronic rhinosinusitis, empty nose syndrome, nasal septal perforations, and laryngotracheal stenosis. One of the most attractive features of CFD technology is the ability to perform virtual surgery and thus to predict how surgical intervention will affect objective measures of upper airway aerodynamics.

The goal of SCONA 2019 is to bring together clinicians and engineers to share their ideas, learn about recent advances in the field, and to facilitate the development and application of CFD technology in sinonasal and laryngeal airway. We will have presentations from leading experts on a range of topics, including advances in virtual surgery planning, diagnosis of nasal airway obstruction via CFD, and optimizing the use of topical medications for more effective treatment of upper airway diseases.

Our conference is being held in conjunction with Rhinoworld Chicago, one of the largest international meetings of rhinologists, otolaryngologists, facial plastic surgeons, and scientists interested in improving treatment of nasal and upper airway diseases. This setting will provide an opportunity for clinicians and engineers to learn from each other and to collaborate towards clinical applications of CFD technology.

As we work to build the conference agenda, please periodically check in here on the conference website for announcements and updates.

We look forward to seeing you in Chicago!
