Abstract

Polysomnography is the gold standard for diagnosing OSA. But as it is costly, effort intensive, and not easily available. Hence, an effective and easy screening test is necessary for predicting OSA.

We tested several measurements from the shadow of head and neck of patients with polysomnography based diagnosis of OSA. These shadows were taken and subsequent different measurements on them were done observing a defined protocol; we named it cephalic shadowmetry. These measurements were compared with polysomnography derived variables and their co-relationships were tested by Pearson's co-relation co-efficient.

There was no statistically significantly co-relationship with. Apnea-hypopnea index (AHI) and any of the cephalometric measurements.
