Diagnostic Procedures

Numerous studies have reported the utility of rhinomanometric analysis in various models of nasal obstruction, including internal valve abnormalities. [8, 9, 10] Rhinomanometry helps to evaluate resistance to airflow but does not provide accurate information about the location of the obstruction. Little data are available investigating rhinomanometric analysis with isolated internal nasal valve dysfunction.

Acoustic rhinometry is a newer technique that is helpful in evaluating the cross-sectional area of the nose and localizing the site of obstruction. [11]

Despite their purported use, much debate still exists regarding the relative inconsistencies between subjective complaints of obstruction and objective measurements and readings. [10] Adequate assessment of internal nasal valve dysfunction and indications for spreader graft placement most often can be made on clinical grounds and physical examination alone.
