ABSTRACT
BACKGROUND:
A reciprocal swelling of the nasal mucosa is often referred to as the classical nasal cycle; however, reports in the literature suggest a more complex picture. Most of the research on the nasal cycle is based on individual measurements. The long-term rhinometry (LRM) now makes it possible to continuously examine the cyclic swelling of the nasal mucosa over 24â¯h. The aim of this study was therefore to evaluate the nasal cycle with LRM over 24â¯h. MATERIAL ANDMETHODS:
An LRM was performed in 55 rhinologically healthy subjects over 24â¯h using the portable measuring system Rhino-Move© (Happersberger Otopront; Hohenstein, Germany).RESULTS:
In addition to the expected strictly reciprocal swelling of the nasal mucosa in the sense of the classical nasal cycle, the following cycle types were detected in-concert type with simultaneous rise and drop of the air flow on both sides of the nose, the one-sided type with significant congestion and decongestion of the mucous membrane only on one side and no detectable changes on the other side of the nose and the non-cycle type without any change in airflow on both sides. Most subjects showed a complex picture with multiple cycle types within the 24â¯h measurement (mixed nasal cycle). The types often differed during the day and night.CONCLUSION:
This study confirms the assumption that the nasal cycle measured over 24â¯h is much more complex than often described in the literature. Most subjects showed several of the 5 cycle types described here. The LRM has proven to be an easy to- use and reliable measurement method. The relationship between cycle type and physical activity as well as other factors remains to be investigated.Palavras-chave
