Study Objectives
The Nasal valve is the primary source of anterior nasal airway resistance, with value pathology significantly contributing to airway obstruction. Surgical procedures which address valve pathology include septoplasty, spreader grafts, and valve M-plasty. However, many patients are either poor surgical candidates or are reluctant to undergo surgery. This study determined the objective validity of a non-surgical approach to the nasal valve using a nasal device.
Study Design
Prospective controlled trial utilizing rhinomanometric measurements of nasal airflow and resistance. Each subject served as his/her own control. Twelve "Normal" adults with no prior history of rhinologic surgery volunteered. Subjects underwent anterior passive rhinomanometry at baseline while wearing the NoseWorks(TM)nasal batten. Rhinomanometric measures of nasal resistance and airflow were measured during normal breathing and supraphysiologic "sniff."
Study Results
Significant differences were demonstrated during both normal breathing and "sniff" for airflow and airway resistance when comparing the NoseWorks(TM) device with baseline measurement at all inspiratory pressures (p < 0.01). During the "sniff," total airflow for subjects using NoseWorks(TM) was 621 ml/sec versus 471 ml/sec at baseline measurement (p < 0.001 by the Students' Two-railed T test).
Study Conclusions
This study provides effective evidence for the use of non-surgical devices within the rhinologist's armamentarium. This device offers a valuable alternative for patients, since it can (1) provide improved nasal airflow for patients who are poor surgical candidates, and (2) simulate the positive surgical results for patients considering surgery.
"For patients who do not wish to have surgery or cannot for any reason, this device can provide a much needed relief of nasal obstruction, snoring, and mouth breathing."
