Tongue Base Reduction with Thyro-Hyoido-Pexy (TBRTHP) vs. Tongue Base Reduction with Hyo-Epiglottoplasty (TBRHE) in mild-severe OSAHS adult treatment. Preliminary findings from a prospective randomised trial.
(74/120)
In a preliminary prospective randomised study, a series of 5 patients submitted to classic Tongue Base Reduction with Hyo-Epiglottoplasty (TBRHE according to Chabolle et al., 1998) is compared to a series of 7 patients submitted to a modified version of Chabolle's procedure. The changes introduced in the new surgical technique can be summarised as follows: a) lower neck skin incision; b) different neurovascular bundle identification; c) submucosal tongue base muscle resection; d) variation of the caudal hyoid stabilisation, already described by the Authors in 2008 (Tongue Base Reduction with Thyro-Hyoido-Pexy). The objective has been primarily to compare the feasibility, functional effectiveness and overall tolerability of the modified procedure. In this preliminary study Tongue Base Reduction with Thyro-Hyoido-Pexy has proven to be an easy and rapid procedure, with shorter post-operative functional recovery and comparable polysomnographic and neuro-psychological short time results.

The efficacy of supraglottic swallow as an indirect swallowing exercise by analysis of hyoid bone movement.
(80/120)
Supraglottic swallow (SGS) is one of the swallowing maneuvers used to enhance safe bolus passage into the esophagus and to avoid aspiration into the trachea. We examined the efficacy of SGS as an indirect swallowing exercise by quantifying hyoid bone movements during SGS. Videofluorography was used to analyze SGS in 10 healthy volunteers. SGS increased the hyoid bone posterior and superior excursion, and maintained these displacements longer, suggesting the effectiveness of the SGS as an indirect swallowing exercise. Thus SGS could be used not only as air way protection but also as an indirect swallowing exercise to strengthen the muscles adhering to the hyoid bone, and to expand the range of motion of the hyoid bone.
