Objective:
To assess soft-tissue variables from CBCT images obtained for dental treatment purposes as potential predictors of OSA severity in adults.
Methods:
This retrospective study included 140 snoring patients categorized by the apnea-hypopnea index (AHI) into primary snoring, mild, moderate, and severe OSA (n =35 per group). Three-dimensional upper airway parameters were measured and compared from CBCT scans. A hierarchical regression model assessed their association with the AHI after adjusting for demographics.
Results:
Multiple CBCT-derived soft-tissue parameters differed significantly among OSA severity groups and correlated with the AHI. However, after demographic adjustment in the hierarchical regression model, only palatal length (PL) and minimal cross-sectional area (mCSA) emerged as statistically significant independent predictors (p < 0.05).
Conclusion:
CBCT revealed significant differences in pharyngeal soft-tissue anatomy among OSA severity groups. Palatal length and mCSA were identified as valuable predictors for OSA screening based on AHI.
