Objective. To evaluate the effect of turbinate sizes on the titrated continuous positive airway pressure (CPAP) therapeutic treatment pressures for patients with obstructive sleep apnea (OSA) who have not had nasal surgery. Study Design. Retrospective case series. Methods. A chart review was performed for 250 consecutive patients. Results. 45 patients met inclusion criteria. The mean ± standard deviation (M ± SD) for age was years and for body mass index was  kg/m2. The Spearman’s rank correlation coefficient () between CPAP therapeutic treatment pressures and several variables were calculated and were weakly correlated (age , nasal obstruction ), moderately correlated (body mass index and lowest oxygen saturation ), or strongly correlated (apnea-hypopnea index and oxygen desaturation index ()). No statistical significance was found with one-way analysis of variance (ANOVA) between CPAP therapeutic treatment pressures and inferior turbinate size (right turbinates value = 0.2012, left turbinate value = 0.3064), nasal septal deviation ( value = 0.4979), or mask type ( value = 0.5136). Conclusion. In this study, CPAP titration based therapeutic treatment pressures were not found to be associated with inferior turbinate sizes; however, the CPAP therapeutic treatment pressures were strongly correlated with apnea-hypopnea index and oxygen desaturation index.
