Number of OSAHS patients successfully treated as a result of OA or CPAP therapy.
Achtergrond van het onderzoek
The Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is common sleep disorder with life threatening sequelae. Continuous Positive Airway Pressure (CPAP) therapy ¡± is currently regarded as the treatment standard for OSAHS. Besides CPAP, dental devices known as Oral Appliances (OA¡¯s) have been of significance in the treatment of this sleep related breathing disorder. However, the evidence-base with respect to the efficacy and co-morbidity of OA therapy in the management of OSAHS is still insufficient.
Primary aim of the present randomised trial is to elucidate the efficacy of, respectively, OA and CPAP therapy in the management of OSAHS. In order to do so eligible OSAHS patients are randomised for either OA or CPAP therapy and followed for a two year period.
On the basis of the study results we hope to elucidate the therapeutic efficacy and the specific indication for, respectively, OA and CPAP therapy in the management of OSAHS. A secondary aim is to find possible prognostic variables for the therapeutic efficacy of OA and CPAP therapy. In addition, we hope to elucidate the co-morbidity of Oral Appliance therapy and explore the therapeutic effect of OA and CPAP therapy on OSAHS related co-morbidity (neurobehavioral dysfunction, deviant driving performance, cardiovascular disease and sexual dysfunction).
Doel van het onderzoek
Primary aim of the randomised trial is to elucidate the efficacy of, respectively, Oral Appliance (OA) and Continuous Positive Airway Pressure (CPAP) therapy in the management of the Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS). It is hypothesized that OA and CPAP therapy are equivalent with respect to the successful management of OSAHS.
Secondary aims of the randomised trial are to elucidate:
- prognostic variables of the therapeutic efficacy of OA and CPAP therapy, respectively.
- co-morbidity of OA therapy.
- the therapeutic effect of OA and CPAP therapy, respectively, on OSAHS related co-morbidity (neurobehavioral dysfunction, deviant driving performance, cardiovascular disease, sexual dysfunction).
