    The Sleep Apnoea Multilevel Surgery (SAMS) trial, a high-quality randomised clinical study, showed that UPPP combined with tongue channelling significantly improved sleep outcomes compared to best medical management in patients unable to tolerate CPAP.

    • Apnoea-Hypopnoea Index (AHI) reduced by 27 events/hr in the surgical group (vs 10 in the medical group)

    • Daytime sleepiness (Epworth Sleepiness Scale) dropped from 12.4 to 5.3 post-surgery

    • Snoring severity, oxygenation, and sleep quality all significantly improved

    • These improvements were durable, with long-term follow-up (~3.5 years) showing ongoing benefit
