To develop a mobile application with a standardized routine, to be used by general otolaryngologists for evaluating patients with chronic rhinosinusitis.

A systematic review was made to identify outcomes, recommendations and what tests that would be used in the routine evaluation of patients with chronic rhinosinusitis; establish an expert consensus on items to be included in this routine evaluation of patients with chronic rhinosinusitis using the Delphi method; development of an application for use on a mobile device, with the routine evaluation of patients with chronic rhinosinusitis.

Based on the systematic review, the outcomes used in studies about chronic rhinosinusitis were identified, as well as guidelines recommendations, which showed discrepancies between them. These recommendations and outcomes were presented to specialists in chronic rhinosinusitis, until a consensus was reached. As a result of the Delphi method, the flowchart of the routine evaluation of patients with chronic rhinosinusitis was defined, and then was used for the development of the mobile application.

The creation of the mobile application for evaluating patients with chronic rhinosinusitis followed an adequate methodology of elaboration made by specialists in the field of chronic rhinosinusitis, standardizing the investigation of these patients.
