Summary
Nasal plasters (NPs) did not significantly improve obstructive sleep apnea (OSA) or snoring based on polygraphic data. However, many users reported improved subjective nasal breathing, suggesting a potential symptomatic benefit.
Area of Science:
- Respiratory Medicine
- Sleep Science
- Medical Devices
Background:
- Nasal plasters (NPs) are increasingly used for obstructive sleep apnea (OSA) and snoring.
- NPs aim to improve airflow by widening nostrils via an elastic spine.
Purpose of the Study:
- To evaluate the efficacy of NPs in treating OSA and snoring without OSA.
- To assess objective polygraphic measures and subjective patient-reported outcomes.
Main Methods:
- Two groups were studied: 30 patients with OSA (Group A) and 20 snorers without OSA (Group B).
- Efficacy was measured using cardiorespiratory polygraphy and a patient questionnaire.
- Polygraphic data included apnea-hypopnea index, desaturation index, and snoring index.
Main Results:
- NPs did not significantly alter polygraphic findings for OSA severity or snoring frequency in either group.
- Subjective improvements in nasal breathing were reported by a majority in both groups.
- While objective measures remained unchanged, 10/30 OSA patients reported improved sleep quality, and daytime sleepiness was unchanged in 90%.
Conclusions:
- Nasal plasters are not an effective treatment for the objective measures of OSA or snoring without OSA.
- NPs may offer symptomatic relief by improving subjective nasal breathing quality.
- Further research could explore the specific mechanisms behind subjective nasal breathing improvements.
