Acoustic rhinometry and its uses in rhinology and diagnosis of nasal obstruction.

Acoustic rhinometry is a tool that can aid in the assessment of nasal obstruction. The test is noninvasive, reliable, convenient, and easy to perform. Common clinical and practical uses of acoustic rhinometry for the rhinologic surgeon include assessment of"mixed" nasal blockage, documentation of nasal alar collapse, and preoperative planning for reduction rhinoplasty. Acoustic rhinometry can also be used to document the positive effect of surgery on nasal airway obstruction.
