Simultaneous videoradiography and solid-state manometry (videomanometry) was applied in eight healthy volunteers (four women, four men; age range 25-64 years, mean age 41 years) without swallowing problems. Three different swallowing techniques were tested; supraglottic swallow, effortful swallow, and chin tuck. Seven videoradiographic variables and six manometric variables were analyzed. The supraglottic swallowing technique did not differ significantly from that of the control swallows. The effortful swallow had a significantly (p = 0.0001) reduced hyoid-mandibular distance preswallow due to an elevation of the hyoid and the larynx, which caused a significantly (p = 0.007) reduced maximal hyoid movement and a significantly (p = 0.009) reduced laryngeal elevation during swallow. The chin tuck swallow had a significantly (p = 0. 001) reduced laryngohyoid distance and also a significantly (p = 0. 004) reduced hyoid-mandibular distance. The chin tuck swallow also displayed significantly (p = 0.003) weaker pharyngeal contractions. Videomanometry allows for analysis of bolus transport, movement of anatomical structures, and measurement of intraluminal pressures. These variables are important when evaluating swallowing techniques. In the present study, we made a few observations that never have been reported before. When healthy volunteers performed supraglottic swallow, they performed the technique somewhat differently. Therefore, we assume dysphagic patients would need a substantial period of training to perform a technique efficiently. Chin tuck could impair protection of the airways in dysphagic patients with weak pharyngeal constrictor muscles.
