Study Details

Brief summary:

About 13% of US adults, some 30 million people, suffer from nasal sinus disease. Although nasal obstruction and smell loss are two of the major symptoms of the disease that are crucial to disease management, currently there is a lack of clinical tools to effectively evaluate the mechanisms contributing to these symptoms. The proposed study aims to develop novel clinical tools to better evaluate and relieve patients' nasal obstructive symptoms and to enable patients and clinicians to make more informed, personalized decisions regarding treatment strategy.

Interventions and Outcome Measures

Arms

other: Single Arm

A device-nasal plug will be self-inserted into the nose with a diagonal channel embedded to redirect nasal airflow patterns to different nasal regions. A nose clip will be used to pinch the nose externally, similar to what synchronized swimmers use.

Interventions

Nasal Plug

Please see the arm description for details.

Primary outcome measure

  • Change in Nasal Obstruction Symptom Evaluation (NOSE) questionnaire [ Time Frame: 3 time points: 1-baseline, 2-after the applications of nasal aid (done on the first day of testing), and 3- 8 weeks after surgery. ]
  • Change in Visual Analog Scale (VAS) of nasal obstruction [ Time Frame: 3 time points:1-baseline, 2-after the applications of nasal aid (done on the first day of testing) and 3-8 weeks after surgery. ]
  • Change in Empty Nose Syndrome 6-Item Questionnaire (ENS 6 Q) [ Time Frame: 3 time points:1-baseline, 2-after the applications of nasal aid (done on the first day of testing) and 3-8 weeks after surgery. ]
