“…This cycle can be interrupted by a reflex mediated by pressure on the side of the chest wall [19][20][21], consequently in the decubitus position, thus the upper nostril becomes clearer and the lower more congested. Recent publications have documented the existence of the nasal cycle during sleep, but the physiological role remains largely unknown [22].…”

Data from observational studies suggest that nasal obstruction contributes to the pathogenesis of snoring and obstructive sleep apnoea (OSA). To define more accurately the relationship between snoring, OSA and nasal obstruction, the current authors have summarised the literature on epidemiological and physiological studies, and performed a systematic review of randomised controlled trials in which the effects of treating nasal obstruction on snoring and OSA were investigated.Searches of bibliographical databases revealed nine trials with randomised controlled design. External nasal dilators were used in five studies, topically applied steroids in one, nasal decongestants in two, and surgical treatment in one study.Data from studies using nasal dilators, intranasal steroids and decongestants to relieve nasal congestion showed beneficial effects on sleep architecture, but only minor improvement of OSA symptoms or severity. Snoring seemed to be reduced by nasal dilators. Nasal surgery also had minimal impact on OSA symptoms.In conclusion, chronic nasal obstruction seems to play a minor role in the pathogenesis of obstructive sleep apnoea, and seems to be of some relevance in the origin of snoring. The impact of treating nasal obstruction in patients with snoring and obstructive sleep apnoea on long-term outcome remains to be defined through randomised controlled trials of medical and surgical therapies.

“…The nasal mucosa is affected by posture (311). It has been shown that the mucosa swells when the posture is changed from upright to supine position and by reflexes producing congestion in the ipsilateral nasal cavity if a lateral pressure is applied to the body (312–316). It is still discussed whether the patency of one side influences the other (317, 318).…”

“…In addition, the airflow changes with the nasal cycle, so the appropriate respiratory resistance and sleep structure during sleep could be adjusted [2]. These changes, in turn, influence tidal volume and oxygen saturation.…”

Nasal cavity ventilation expansion surgery has been progressively developed alongside an advanced understanding of the pathophysiological mechanisms of sleep-disordered breathing and the maturation of endoscopic surgery techniques. Nasal cavity ventilation expansion surgery could increase the ventilation volume of the nasal cavity effectively and decrease the nasal resistance, relieve the upper airway obstruction, and finally remove the original obstructive factor in the upper airway obstruction. The major significance of these procedures is to decrease the pre-ventilation resistance of the upper airway, to relieve pharyngeal collapse, to recover normal ventilatory function, to promote physical recovery, to re-establish normal metabolic functions, and to restore sleep structure. Nasal cavity ventilation expansion surgery includes a series of procedures and to open nasal sinuses symmetrically could decrease the nasal resistance, relieve the upper airway obstruction, and finally remove the original obstructive factor in the upper airway obstruction. The application of endoscopic surgery to obstructive sleep apnea (OSA) enhances the ventilation volume and symmetry of nasal cavity ventilation and has expanded the range of indications for which functional endoscopic sinus surgery (FESS) is effective. Combined with H-uvulopalatopharyngoplasty (H-UPPP), the outcome of surgical treatment on ventilation disorders of the upper airway obstruction and the symptoms of OSA will both be improved.
