Chapter 14: Other Therapies and Emerging Options for Management of OSA.
For patients unable to tolerate CPAP, several alternatives exist. Positional therapy benefits patients with position-dependent OSA (prevalence 50–70%), using devices from tennis balls to vibrating neckbands, though long-term compliance remains poor (<40% at 6–30 months). Weight loss—via lifestyle intervention, VLCD, or bariatric surgery—produces dose-dependent AHI reduction, with surgical approaches (e.g., RYGB, biliopancreatic diversion) outperforming medical weight loss. Nasal EPAP and oral pressure therapy (Winx) offer modest, variable efficacy (30–40% responder rates) with tolerability issues. Hypoglossal nerve stimulation (Inspire) shows durable results in properly selected moderate-to-severe OSA patients (BMI ≤32), with ~65% long-term response and stable AHI reduction at 3 years.
