Super-Supraglottic Swallow Combined with Head Flexion Strengthens Laryngeal Closure.

The study was conducted only on healthy young adults, so the results may not apply to patients with dysphagia, who often have impaired laryngeal closure. The modified maneuver used in this study omitted the 'inhale' and 'cough' components typically included in the standard super-supraglottic swallow description, limiting generalizability to the full clinical procedure. Participants were instructed in the maneuvers immediately before the experiment, and the trial with the best performance (shortest DEA) was analyzed, which may overestimate the real-world efficacy of the technique. The order of tasks was not fully randomized; usual swallowing was always performed first, which could introduce fatigue or learning effects.

The study was funded by The Research Funding for Longevity Sciences. No other conflicts of interest were reported.

Do not assume this maneuver improves swallowing safety in patients with dysphagia. The study was conducted only on healthy adults with no baseline aspiration, and the authors explicitly state that further testing in dysphagic patients is required.
