Thirty-five alternatives to positive airway pressure therapy for obstructive sleep apnea: an overview of meta-analyses.

ABSTRACT

INTRODUCTION: Positive airway pressure (PAP) devices are generally considered to be the first-line treatment of choice for most adults with obstructive sleep apnea (OSA). However, there are several alternatives. It is important for patients and their sleep providers to be aware of the most up-to-date information regarding the current international literature. Areas covered The objective is to provide an overview of the meta-analyses evaluating non-PAP treatments for OSA. Four authors searched four databases, including PubMed/MEDLINE through 30 November 2017, for meta-analyses evaluating non-PAP therapies as treatment for OSA. Thirty-five non-PAP treatments were identified and were categorized based on the following anatomical subsites (1) nose, (2) palate and oropharynx, (3) tongue, (4) skeletal surgery and jaw repositioning, and (5) other surgical and medical interventions. Treatments identified included surgeries, drugs, behavior modifications, nonsurgical weight loss, medical devices, body positioning, and oxygen treatment. Expert commentary The 35 treatments described vary in their effectiveness in treating OSA in adults. In general, isolated nasal treatments are the least effective, whereas treatments that bypass the upper airway, significantly open the upper airway, and/or address multiple levels of the upper airway are more effective in improving apnea-hypopnea index and lowest oxygen saturation.
