Obstructive sleep apnoea treatment options
Treatment options for obstructive sleep apnoea (OSA) include three forms of positive airway pressure (PAP) therapy, oral appliance therapy, and alternative therapy.
Positive airway pressure therapy
Positive airway pressure therapy is the most effective way to treat OSA. By creating a ‘pneumatic splint’ for the upper airway, PAP therapy prevents the soft tissues of the upper airway from narrowing and collapsing. Pressurised air is sent from a therapy device through air tubing and a mask to the upper airway.
Patients with severe sleep apnoea are able to experience restful sleep with positive airway pressure therapy. PAP therapy can be delivered in a number of ways:
- Continuous positive airway pressure (CPAP): pressurised air at one fixed pressure;
- Automatic positive airway pressure (APAP) therapy: automatically adjusted air levels based on a patient’s breathing (suited to patients with REM-related sleep apnoea, positional apnoea or those who are non-compliant with standard CPAP therapy);
- Bilevel therapy: higher inspiratory pressure and lower expiratory pressure (appropriate for certain patients who are non-compliant).
Oral appliance therapy
An oral appliance, also known as a mandibular repositioning device (MRD), is a first line treatment option for mild and moderate obstructive sleep apnoea and a second line treatment option for severe OSA. OSA patients who are non-compliant with or refuse positive airway pressure therapy often use oral appliances as an alternative therapy. Some OSA patients also prefer oral appliances because they are non-invasive, easy to wear and easy to transport.
Oral devices work by holding the lower jaw in a forward position during sleep to reduce collapse of the airway and expand space behind the tongue, which helps prevent apnoea and snoring.
Alternative treatment options
Surgery is also an option for treating obstructive sleep apnoea (OSA), though it comes with associated risks and complications. Uvulopalatopharyngoplasty (UPPP), the most commonly performed surgical procedure for OSA in the United States, is effective in reducing snoring initially. Over the long term, UPPP cures snoring in 46% to 73% of patients who have had the surgery.1
