Objective:
Evaluation of the presence of nasal septal deviation in patients presenting with obstructive sleep apnea (OSA) using Cone-Beam Computed Tomography (CBCT).
Method:
Patients diagnosed with OSA using polysomnography were further evaluated radiographically for the presence of nasal septal deviation, maxillary sinus septa, and oropharyngeal airway volume using CBCT.
Results:
Nasal deviation was present in all the patients and was classified according to Negus et al classification, further categorized with Apnea-hypopnea index (AHI) score, maxillary sinus septa in those patients were classified according to Al Faraj et al, and the oropharyngeal airway volume was found to be an average of 10,086.37 ± 3966.116 mm2 airway volume.
Conclusion:
All the patients in the study had nasal septal deviation, hence it can be considered as a radiographic marker in suspecting OSA.
