Abstract
A number of therapeutic alternatives to continuous positive airway pressure (CPAP) and surgery have been proposed to treat sleep apnea syndrome. Nasopharyngeal intubation may provide an immediate, simple and cost-effective means of bypassing upper airway obstruction during sleep. Tolerance is good in small children but is lower, between 30 and 40%, in adults. Clinical improvement is reported by more than half of the patients treated with this device and is confirmed by polysomnography. However, in most of these subjects, breathing during sleep is only partially corrected and sleep remains fragmented. Nasopharyngeal intubation should be proposed in infants, in patients who do not tolerate CPAP or as a therapeutic substitute for CPAP during holidays or traveling. The tongue retaining device and variants of orthodontic appliances have been proposed in order to increase upper airway patency. Tolerance is low, efficacy is usually incomplete and limited to patients with moderate forms of SAS, and long-term follow-ups are scarce. Sleep position training has been advocated as a means of reducing time spent in the supine position. Long-term efficacy has not been proven. Weight loss by caloric restriction or surgical procedures produces a variable improvement of sleep architecture and breathing during sleep. It should be proposed to all patients with SAS, as cure has been achieved in a few patients with the adjunction of weight loss and another treatment modality.
