A comparison of active anterior rhinomanometry and nasometry in the objective assessment of nasal obstruction.
Nasometry is an objective technique that was originally devised for assessing nasality of speech. It is based on a comparison of the acoustic output from the nose and the mouth for a given spoken word or phrase. Subjects with nasal obstruction tend to have "hyponasal" speech and this study compares the standard technique of active anterior rhinomanometry with nasometry in the objective assessment of nasal obstruction. There was a significant association between the Total Nasal Resistance (TNR) and the nasality measurements using nasophonemically enhanced test phrases in 15 adult subjects. This test has obvious advantages over rhinomanometry which can be difficult, time consuming and unreliable particularly in the younger and severely congested patient.
