Study Summary
The purpose of our study is to correlate nasal volume and cross-sectional area with nasalance scores. We will measure nasal volume and cross-sectional area with acoustic rhinometry. Nasalance scores will be determined by Nasometry. Acoustic rhinometry is a means to study the volume and cross-sectional areas of the nasal cavity in a non-invasive, rapid, convenient and reliable manner. Acoustic rhinometry has the unique advantage of being completely non-invasive, and thus is able to measure nasal patency without the confounding effects of probes or invasive monitoring. Nasometry is a technique to measure the oral and nasal components of nasalance. Nasalance is the objective measure of the nasal component of speech that is determined by the ratio of sound pressure emitted from the nasal and oral cavities during speech. Nasality is the term used to characterize the nasal component of speech, and is a subjective measure. Eleven healthy subjects underwent acoustic rhinometry pre and post decongestion using oxymetazoline 0.05% nasal spray. Nasalance scores were based on the readings of three passages: rainbow, zoo, and nasal.
