[Sleep apnea : diagnostic and therapeutic modalities in case of failure of the CPAP].

Obstructive sleep apnea (OSA) is a sleep disorder that affects 49 % of men and 23% of women over 40 years old. CPAP is currently the treatment of choice for severe OSAS, but there are mild to moderate cases of OSAS with poor compliance or intolerance to CPAP, for which alternative treatments should be considered.
