The following excerpt is from Dr. Gerard O’Halloran’s book for Non-ENT Physicians entitled The Nose in 60 Minutes.
INTERESTING FACT: THE NASAL CYCLE
80% of the population has a nasal cycle. The turbinates on one side of the nose are alternately more swollen than those on the other side. This turbinate congestion changes sides every 4 – 8 hours.
Most patients are not aware of this cycle because there is an open breathing passage on the non-congested side and a partially open breathing passage on the congested side. If a patient complains of alternating nasal congestion (notices the nasal cycle), it often means that the turbinates are chronically enlarged from vasomotor rhinitis or chronic allergic rhinitis or that the nasal septum is deviated.
Chronic turbinate enlargement and/or a deviated septum narrow the nasal airway. When cyclic enlargement of the nasal turbinates on one side of the nose occurs in a patient with an already narrowed nasal airway, the nasal passage on the congested side may become nearly completely obstructed and therefore noticeable to the patient.
