Very high structure, hybrid amorphous silica products having very high absorptivity, in which the hybrid silica product has a % carrying capacity DBP value greater than 76. A lockable vertical rotation of said camera mount is achieved by means of an input and output section, one able to pivot relative to the other due to guide pins restrictedly able to move within guide tracks and studs to restrictedly move within elongated channels. The method may comprise advancing a suture and hook from the subject’s anterior thyroid cartilage or cricothyroid membrane to the muscular process of the subject’s arytenoid, attaching the hook to the muscular process, and applying tension to the suture to rotate the muscular process and adduct the arytenoid.
