Official title

Assessing Mechanical Nasal Obstruction, a Potential New Treatment Option.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The research team has developed a prototype for an investigational mechanical nasal dilator and the investigators aim to evaluate its efficacy. Specifically, the investigators wish to address the following research questions: 1) How does mechanical nasal obstruction affect patients' lives? The investigators aim to answer this question with use of validated questionnaires. 2) How do currently available mechanical nasal dilators affect objective and subjective findings related to nasal obstruction? This will be evaluated with objective nasal airflow testing and with modifications to validated questionnaires 3) How does the investigational team's novel device affect these same outcome measures? 4) Do patients find the investigational device subjectively comfortable and efficient?
