Abstract Objective To investigate the clinic value of supine DR dual-energy subtraction (DES) in auxiliary diagnosis of obstructive sleep apnea hypopnea syndrome (OSAHS). Methods Thirty-three patients with OSAHS proved by clinic and polysomnograph underwent the conventional digital radiography (DR) and DES examinations of nasopharyngeal part. Every patient was in supine position for DES. Micrognathism was not pathogenic cause in all patients.The morphological findings of soft palate, uvula and tongue root, as well as airway strictures at corresponding site, were evaluated by three radiologists respectively. The results were statistically analyzed with ROS curve. Results For the detection of airway strictures at retropalatal and retroglottal region level, the area under ROC curve in DES group:Doctor 1(0.921/0.974),Doctor 2(0.950/0.942),Doctor 3(0.913/ 0.977),was larger than that in DR group:Doctor 1(0.798/0.716),Doctor 2(0.771/0.583),Doctor 3(0.632/ 0.697),and there was significant difference between these two groups (P<0.05). As for the detection of soft palate loosening and tongue root retrusion, the area under ROC curve in DES group of patients at supine position was also significantly larger than that in DR group with P<0.05. Conclusions DES technique is obviously superior to conventional DR examination on exploring pathogenic cause of OSAHS, especially for displaying soft palate loosening and tongue root retrusion when DES examinations are performed at supine postures. This technique can eliminate efficiently the influence of bone tissue shadows. It is beneficial to showing pathological changes more clearly, measuring the airway and guiding the clinical therapy.
