A combined application of acoustic rhinometry, rhinoresistometry, and flow simulation of the nose mucosa before and after turbinate surgery: a model study.
The interpretation of rhinometric results seems difficult, particularly in young examiners. In order to follow rhinometric assessments precisely, the knowledge of the nose airflow mechanisms is necessary. In this direction, in a model study the consequences of nasal concha surgery on acoustic rhinometry and rhinoresistometry were systematically investigated. Six nose models were examined through acoustic rhinometry and rhinoresistometry approaches. Each model reflected conditions happened after the nasal concha surgery. All models were also rinsed with the water while the flow outputs were visualized for the checking. The normal nose was represented an even flow distribution over the entire nasal cavity. After the nasal concha resection, a deviant flow course and a significant grow in turbulence activity were seen. A flow resistance dropped in addition considerably. In the model with general lateral wall hyperplasia, a restriction of the inferior and even of the middle nasal concha led to the beneficial functional results. The models demonstrated a positive correlation between the flow data and acoustic rhinometry and rhinoresistometry measures. Both methods complement each other in the diagnostic outcome of the nose functioning.
