Clinical Trial Summary

Nasal obstruction is a common complaint prompting presentation to an otolaryngologist. Many studies have been performed quantifying and describing the impact of a number of factors on symptoms of nasal obstruction, including anatomical, neoplastic, infectious, and inflammatory causes. Despite this scrutiny, no attention has been paid to the nasal vibrissae as a potential anatomical contributor to nasal obstruction. The proposed study intends to elucidate that contribution, if any exists.

Outcome
Type Measure Description Time frame Safety issue
Primary Nasal airflow/pressure Objective measures include airflow and pressure as assessed by Rhinomanometry. Participants will undergo assessment over a 30 minute period, no follow-up
Primary Subjective Nasal Obstruction Subjective measures will be assessed via the modified version of the NOSE outcome instrument-a validated test of subjective nasal obstruction Participants will undergo assessment over a 30 minute period, no follow-up
