Nasal cavity structural anomalies in children and adolescent
In this study, researchers investigated the presence of structural anomalies in the nasal cavity (deviated nasal septum [DNS] and turbinate hypertrophy [TH]) in patients at high risk or not of sleep-disordered breathing (SDB).

A retrospective study considering available cone-beam computed tomography scans of 99 patients was conducted. Dolphin Imaging software was used to process the craniofacial scans. A pediatric sleep questionnaire (PSQ) was used to suggest a high risk of SDB. Subjective and objective assessments of DNS and TH were considered.

- Good to excellent intrareliability and interreliability was attained. The prevalence of a PSQ score suggestive of a high risk of SDB in this sample was 59%. The prevalence of subjective DNS and TH assessment was 64% and 70%, respectively.

- In contrast, on the basis of objective assessments, 27% of patients presented with DNS and 25% with TH.

- Cross-tabulation of DNS and TH with PSQ score indicated a statistically significant association between subjective DNS and subjective TH and subjective TH and positive PSQ.

- A positive correlation between age and subjective and objective DNS assessments was also observed.

Older patients are more likely to present with DNS. Only the presence of subjectively determined TH in patients is associated with a high risk for SDB. The study reveals that assessment of DNS and TH using cone-beam computed tomography imaging is not likely suitable to strongly suggest patients at high risk for SDB. DNS subjective assessments were capable of identifying less than 5% of deviation.
