Snoring Is Not Relieved by Nasal Surgery Despite Improvement in Nasal Resistance: Conclusions

It is, of course, possible that our negative findings are only due to the methodology. Discordance between perceived and recorded snoring has been reported. The results may differ depending on the population studied. Whether a single-night recording of snoring is adequate remains unknown as the repeatability of these measurements is also unknown. Furthermore, how much nasal resistance should be reduced to show a possible effect on snoring also is not clear.
In addition to relieving symptoms of nasal stuffiness, the treatment of nasal obstruction has been shown to decrease the needed pressure levels in nasal continuous positive airway pressure therapy, and it may increase adherence to the treatment.

Although nasal obstruction seems to predispose patients to snoring and probably to SDB, the relief of nasal obstruction by nasal surgery as a single treatment for snoring or SDB does not seem adequate in a clinical population of problem snorers. Only some habitual snorers develop obstructive sleep apnea, and the factors influencing the course of the disease are poorly understood. Inflammation, snoring trauma, and changes in the pharyngeal soft tissues have been related to the development of obstructive sleep apnea. Changes in the upper airways over the course of years may decrease the effect of a unilevel treatment in patients with snoring and SDB. Nasal mucosal inflammation in patients experiencing habitual snoring and SDB may be a predisposing factor but may also be a consequence of the disease process. my canadian
Moderate treatment results of sleep apnea in unselected patients with rhinitis symptoms are in agreement with this hypothesis. The treatment of nasal inflammation as well as structural obstruction may improve treatment results in the short term and may prevent more severe disease in the long term.
Snoring time and intensity measured during PSG were not improved by the treatment of structural nasal obstruction despite significant decrease in nasal resistance. Nocturnal breathing also did not improve significantly in these consecutive snoring men. Cephalometry for the prediction of treatment outcome will need further evaluation. Snoring intensity seems to be higher during NREM sleep when compared with REM sleep, which may have social implications predominantly during the first hours of sleep.
