Purpose
The purpose of this study was to compare the effectiveness of nasal pillows with standard nasal masks in the treatment of patients with obstructive sleep apnea (OSA).
Methods
A digitalized search was carried out in four different databases including PubMed, Scopus, EMBASE, and CENTRAL using relevant keywords along with a manual search in relevant journals. All comparative studies comparing outcomes of using a nasal pillow with the use of standard nasal masks for continuous positive airway pressure (CPAP) treatment in patients with OSA were included. The qualitative analysis was carried out by tabulating the demographic data. The quantitative data were subjected to meta-analysis. The quality of comparative studies (both retrospective and prospective cohorts) was evaluated using New-castle Ottawa scale (NOS).
Results
A total of 14 studies (eight prospective and six retrospective) were included in the review. Of them, five studies were randomized and were of cross-over study design. No significant differences were observed in achieved CPAP and residual apnea–hypopnea index (AHI) levels between the nasal pillow and nasal mask with SMD − 0.05 95% CI [− 0.18, 0.09], p = 0.50 and SMD − 0.13 95% CI [− 0.28, 0.03], p = 0.12, respectively. However, nasal pillow usage was associated with better CPAP adherence with a difference of only + 0.29 min/night as compared to a standard nasal mask, with SMD 0.29 95% CI [0.07, 0.50], p = 0.009.
Conclusion
Nasal pillow and standard nasal mask were equally effective in terms of residual AHI level and achieved similar therapeutic CPAP pressures. However, the difference in CPAP adherence between groups, though statistically significant, is of questionable clinical significance.
