nasal cycle

Respiratory physiology Alternating congestion and decongestion of the nasal airway that occurs in 70% of adults, controlled by the autonomic nervous system, and which may be affected by circadian changes in hormone levels, temperature, humidity, posture, and emotion; in the face of a unilateral fixed obstruction, the congestion phase of the side opposite the obstruction may be interpreted as an abnormality of the normal side or 'paradoxic nasal obstruction'

A differential diagnosis of reversible nasal congestion includes allergic rhinitis, nonallergic rhinitis, vasomotor rhinitis, exaggerated nasal cycle, acute viral rhinitis, acute viral rhinosinusitis, acute bacterial rhinitis, acute bacterial rhinosinusitis, chronic inflammatory or infectious rhinosinusitis, rhinitis medicamentosa, sarcoidosis, Wegener's granulomatosis, Churg-Strauss syndrome, and rhinoscleroma [20].
To reduce bias by the nasal cycle, rhinomanometry and imaging were performed during the same cycle pre-and postoperatively.
They shift their workload back and forth in the nasal cycle. At any moment, most of the air you inhale travels through just one nostril, while a much smaller amount enters through the other.
The one-to-four hour nasal cycle results in the inferior turbinate on one side be- ing engorged for a time, followed by engorgement of the other side.
Periodic nasal congestion and decongestion have been termed the "nasal cycle" by Heetderks [9].

For a proper and efficient nasal cycle, the turbinates need a rigid septum to be their reference point.
To decrease the effects of the nasal cycle, our subjects were measured at approximately the same time of day at both testing sessions.
The most common structural abnormality is a deviated nasal septum, which can cause a sensation of chronic unilateral nasal congestion or congestion that fluctuates with the nasal cycle. The patient might report a history of nasal trauma.
