Detaljerad beskrivning
6% to 13% of the western industrialized population suffer from obstructive sleep apnea (OSA). During sleep in the pharyngeal airway a relaxation of the muscles occurs with increasing depth of sleep. Finally, this relaxation, due to the anatomical conditions, lead to obstructions of the respiratory tract, resulting in respiratory arrest (apnea) and minor respiratory changes such as hypopneas or flow limitations. The symptoms of this disease manifest themselves with varying degrees. Increased daytime sleepiness, snoring, and increased risk of cardiovascular disease can result. A significant reduction in overall quality of life can be associated with OSAS. The gold standard treatment for obstructive sleep apnea is CPAP (continuous positive airway pressure). But only about 50% to 70% of patients continue to use their device after 2 years of initial CPAP therapy. This means that 30% to 50% of patients are no longer cared for their obstructive sleep apnea. A certain proportion of younger patients, in particular, reject nocturnal ventilation therapy with CPAP from the beginning. For these patients selective upper airway stimulation (UAS) is a therapy option.
Therefore the patient receives surgically a subcutaneous stimulation device under the clavicle, which receives a signal from a respiratory sensor to selectively stimulate the hypoglossal nerve. The respiratory sensor is located in the 4th or 5th intercostal space between the patient's external and internal rib muscles. This can be used to record the patient's breathing, which allows a matched stimulation of the hypoglossal nerve. The actual stimulation lead is attached to the medial branches of the hypoglossal nerve, which are responsible for the protrusion of the tongue, in order to enable appropriate stimulation.
In this prospective cohort study, selective upper airway stimulation (UAS) will now be compared with CPAP therapy. Patients receiving CPAP therapy are compared to UAS patients who receive an upper airway stimulation. Both methods are procedures established in clinical routine, and during this investigation, the general clinical course is not deviated. Randomization does not occur because CPAP therapy is a conservative therapy and UAS therapy is a surgical therapy. Furthermore, for UAS therapy, there must be a CPAP incompliance, so that a surgical concept is justified. The CPAP group should comply with the body mass index and age of the UAS group.
