Mandibular advancement device use in obstructive sleep apnea: ORCADES study 5-year follow-up data.

Study Objectives: Mandibular advancement devices (MADs) are an alternative to continuous positive airway pressure for the management of obstructive sleep apnea (OSA). The ORthèse d'avanCée mAndibulaire dans le traitement en DEuxième intention du SAHOS sévère (ORCADES) study is investigating the long-term effectiveness of MAD therapy in patients with OSA who refused or were intolerant of continuous positive airway pressure. Five-year follow-up data are presented.

Efficacy and tolerability of a custom-made Narval mandibular repositioning device for the treatment of obstructive sleep apnea: ORCADES study 2-year follow-up data.

Objective/background: Mandibular repositioning device (MRD) therapy is an alternative to continuous positive airway pressure (CPAP). The Orkney Complex Disease Study-ORCADES study is assessing the long-term efficacy and tolerability of MRD therapy in obstructive sleep apnoea syndrome (OSAS); two-year follow-up data are presented.

Patients/methods: OSAS patients who refused or were noncompliant with CPAP were fitted with a custom-made computer-aided design/computer-aided manufacturing (CAD/CAM) bi-block MRD (ResMed, Narval CC™); mandibular advancement was individually titrated.

Sex differences in mandibular repositioning device therapy effectiveness in patients with obstructive sleep apnea syndrome.

Purpose: Mandibular repositioning devices (MRDs) are an effective treatment option for obstructive sleep apnea syndrome (OSAS), particularly in patients who refuse or cannot tolerate continuous positive airway pressure (CPAP). However, sex differences in the response to therapy and predictors of response are not clearly defined. This analysis of data from the long-term prospective ORCADES trial compared MRD efficacy in men and women with OSAS.

[Validated tools for clinical evaluation of circadian rhythm sleep disorders in adults and children].

Circadian rhythm sleep-wake disorders are characterized either by sleep schedules that do not correspond to the usual schedules usually imposed by the light/dark cycle and by socio-professional activities, or by an unusual number of sleep episodes 24h. These two anomalies of the sleep-wake cycle are caused by an alteration of the circadian system or its mechanisms of entraining. The clinician has various tools that will confirm the diagnosis of circadian rhythm sleep-wake disorders.

A custom-made mandibular repositioning device for obstructive sleep apnoea-hypopnoea syndrome: the ORCADES study.

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(™) MRDs for obstructive sleep apnoea-hypopnoea syndrome (OSAHS) patients.
