Summary
Elevated nasal resistance may contribute to obstructive sleep apnea, but this study found it is not a major factor in severe cases. Further research is needed to fully understand the nose's role in sleep apnea.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Respiratory Physiology
Background:
- The nose can function as a Starling resistor.
- Elevated nasal resistance might increase negative pharyngeal pressure, potentially causing obstructive sleep apnea.
Purpose of the Study:
- To investigate the hypothesis that increased nasal resistance contributes to obstructive sleep apnea.
- To determine if nasal resistance correlates with obstructive sleep apnea severity.
Main Methods:
- Nasal resistance studies were conducted.
- 37 healthy subjects and 53 patients with obstructive sleep apnea participated.
Main Results:
- Patients with obstructive sleep apnea exhibited significantly higher nasal resistance compared to controls.
- Increased nasal resistance did not correlate with parameters predicting obstructive sleep apnea severity.
Conclusions:
- While the nose may play a role in sleep apnea, nasal resistance is not a primary driver of severe obstructive sleep apnea.
- Further investigation is warranted to elucidate the nose's contribution to sleep apnea pathogenesis.
