Compliance to CPAP is sometimes a problem, and mandibular advancement device (MAD) is then an alternative. However, this alternative is often not effective. It was hypothesized that patients suffering from OSAS would have a freer airway, resulting in a decreased apnea-hypopnea index (AHI), through use of a cervical collar (CC) to extend the neck. To study the effect of this new therapy, a randomized crossover study was conducted to compare MAD monotherapy with CC/MAD combination therapy. Methods: Eight patients with severe OSAS (AHI>30) who had ceased to use CPAP were enrolled in the randomized crossover study. Four patients started with MAD and four with CC/MAD for one week followed by a wash-out period and then cross-over. Polygraphic sleep recordings were performed at baseline and after each therapy. Results: The baseline AHI was 51.5 ¡À 22.5. AHI was reduced to 30.4 ¡À 23.2 through MAD monotherapy, and to 14.9 ¡À 10.2 through CC/MAD combination therapy. The effect of the combination therapy was statistically significantly (p=0.018) better than that of the monotherapy. Four patients were achieved an AHI<10/h through use of the combination therapy. Concusions: The study showed a significant reduction in AHI scores in patients with severe OSAS through use of the CC/MAD combination therapy as compared to the MAD monotherapy. This first report indicates a new possibility for treating severe OSAS in non-compliant CPAP users. %K Florim Delijaj %K Gustaf Levin %K Eva Lindberg and Eugen Wang %K Cervical collar %K CC/MAD combination therapy %K Noncompliant CPAP users %K Obstructive sleep apnea %U https://www.longdom.org/abstract/reduced-apneahypopnea-index-in-patients-with-severe-sleep-apnea-syndrome-as-determined-by-cervical-collar-and-mandibular-30555.html
