An assistant can gently pull the right side of the patient's lip and cheek to enhance visibility of the glottis.
In hiccupping, we use ancient muscles to quickly close the glottis while sucking in (albeit air, not water).
For selected cases, using omohyoid myofascial flap to repair the partial laryngeal defect and reconstruct glottis is available and practicable.
When underwater, the animals pushed water past their gills while simultaneously pushing the glottis down.
