About this study
Official title: Correlation of Nasal Volume and Cross-Sectional Area With Nasalance Scores as Measured by Acoustic Rhinometry and Nasometry
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.
Read the detailed description
Acoustic rhinometry is a technique that utilizes sound waves to measure nasal patency. The reflections of the waves off of the nasal structures allow one to assess the volume and cross sectional area of the nasal cavity. It is a non-invasive procedure that can be performed in a rapid, convenient, and reliable manner. There is minimal discomfort for the patient and it can be performed easily in the office. There is no distortion of nasal anatomy or functioning as a result of the procedure.
Nasometry is a technique to measure the oral and nasal components of nasalance. Nasalance is an objective measure of the nasal component of speech that is determined by the ratio of acoustic pressures emitted from the nasal and oral cavities. 'Nasality' is the term used to characterize the nasal component of speech, and is a subjective measure.
The Nasometer (Kay Elemetrics Corp Lincoln Park, NJ) is a computer-based device that analyzes acoustic energy that is emitted from the oral and the nasal cavity during speech. It consists of two microphones that are separated by a plate. The upper microphone measures nasally emitted acoustic energy, and the lower microphone measure the acoustic energy emitted from the oral cavity.
Nasalance is an important measure in speech pathology. In situations where velopharyngeal competence is in question, nasometry objectively documents the nasal component of speech as normal, hypemasal or hyponasal. It has been found to be of tremendous benefit in the management of patients with cleft palate and velopharyngeal incompetence. The subject is relaxed, and is fitted with a headgear apparatus. This apparatus is placed such that a plate lies in a horizontal plane that rests midway between the nose and the mouth. There are microphones on the upper and lower surfaces of the plate that capture sound energy produced from the nasal and oral cavities respectively. The subject is then asked to read standard passages. The three most commonly used passages are described here, and will be used in our study. The 'Rainbow' passage is most representative of standard English speech. The 'Zoo' passage has no nasal consonants, and the 'Nasal' passage has the highest number of nasal consonants.
While the subject is reading, the microphone captures sound pressure levels which are emitted from the nasal and the oral cavities. This data is analyzed by the attached computer and presented graphically. The computer also provides a nasalance score for each of three above- mentioned passages. Normative data is available for each of these passages for adults and children. By comparing the data obtained from the subject with the normative means and standard deviations, the investigator can categorize the subject's voice as normal, hyponasal or hypernasal. The nasalance score that is generated can also be used to monitor the efficacy of speech therapy and surgical interventions.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Acoustic rhinometry (procedure) in people with Allergy, run by University of Chicago at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 12 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Nasal volume. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00147940, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2013.
