The main objective of this project is to develop a quick and efficient screening instrument to accurately identify individuals with olfactory dysfunction (from all causes of olfactory dysfunction). We hope to systematically develop an olfaction screening instrument that is highly correlated to objective olfaction, as currently, this does not exist. Our overall hypothesis is that we can reliably predict an abnormal objective olfaction score using the screening instrument we develop.

This study will examine genetic information from individuals with chronic rhinosinusitis, as well as individuals without chronic rhinosinusitis, for the purposes of better understanding what causes sinusitis. A salivary sample will be collected from each subject which contains genetic material. Additionally, subjects will complete a brief questionnaire covering demograhics, other medical conditions, and severity of sinusitis.
