NCT00683254

Brief Summary

Commercially-available internal nasal stents placed inside the nostril should produce decreased nasal obstruction detectable subjectively (volunteers will fill out a survey) and objectively (degree of obstruction will be measured with a rhinomanometer which measure resistant of airflow while breathing through nose).

Outcome Measures

Primary Outcomes (1)

  • change in resistance to airflow after stents inserted as measured by rhinomanometer

    data collection occurs at one time only, takes less than 5 minutes to record

Secondary Outcomes (1)

  • subjective decrease in nasal obstruction after stents placed recorded by volunteers filling out a survey

    recorded at time of stent placement, one time only

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Our subject pool will be comprised of healthy volunteers, at least 18 years of age, who have not had nasal surgery, are not currently using a topical decongestant, topical nasal steroid spray, or over the counter decongestant, and have no history of recurrent epistaxis or a running nosebleed within 2 weeks prior to data collection.

You may qualify if:

  • years or older

You may not qualify if:

  • history of nasal surgery, currently using topical nasal steroid spray, over the counter decongestant, history of recurrent epistaxis or history of nosebleed within 2 weeks prior to data collection, currently pregnant
