• Obstructive sleep apnoea
• Mandibular repositioning device
• Compliance
• Tolerance

Background: Mandibular repositioning devices (MRDs) are usually recommended as the first therapy option in patients with mild-to-moderate obstructive sleep apnoea (OSA). However, data on the long-term efficacy of MRDs are limited, not only in OSA patients who are noncompliant with continuous positive airway pressure (CPAP) but also in those with more severe OSA. The ORCADES study aimed to prospectively determine the long-term efficacy and tolerability of two custom-made Narval (TM) MRDs for obstructive sleep apnoea-hypopnoea syndrome (OSAHS) patients. The interim 3- to 6-month data are reported.
Methods: Eligible patients had OSAHS and had refused or were noncompliant with prescribed CPAP. Outcome measurements after gradual mandibular advancement titration included: apnoea-hypopnoea index (AHI), oxygen saturation, sleepiness, symptoms, quality of life, side effects and compliance.
Results: A total of 369 patients were included. Overall, MRD treatment was successful (>= 50% decrease in AHI) in 76.2% of the participants; complete response (AHI <10/h) was achieved in 63.5%. Severe OSAHS was effectively treated (AHI <15/h) in about 60% of the participants; 38% had complete symptom resolution. Mandibular repositioning devices significantly decreased subjective sleepiness, eliminated symptoms and improved quality of life. They were well tolerated and compliance was excellent. Only 8% of the participants stopped MRD treatment due to side effects.
Conclusion: Custom-made Narval (TM) MRDs are effective for mild to severe OSA in patients who refuse or are noncompliant with CPAP. They are well tolerated and have excellent compliance.
