(19) To determine where and how muscles affect pharyngeal stability, we assessed in heavily anesthetized, ventilated dogs, the negative pressure required to close the nasopharynx and the passage from the oral to the pharyngeal airway before and after electrical stimulation of six pairs of upper airway muscles: the sternohyoid, sternothyroid, ceratohyoid, thyrohyoid, genioglossus, and geniohyoid.
(20) The geniohyoid has been characterized as a parallel-fibred muscle extending from the mandibular symphysis to the hyoid body.
Hyoid
Definition:
(a.) Having the form of an arch, or of the Greek letter upsilon [/].
(a.) Of or pertaining to the bony or cartilaginous arch which supports the tongue. Sometimes applied to the tongue itself.
(n.) The hyoid bone.
Example Sentences:
(1) The duration and "growth guidance" aspects of treatment allowed for functional as well as morphologic adaption to the altered hyoid position.
(2) Primitively, vibrations reached the stapes mainly via the anterior hyoid cornu, but in dicynodonts, therocephalians, and cynodants vibrations passed mainly or exclusively from mandible to quadrate to stapes and the reflected lamina was a component of the eardrum.
(3) The cranial force displacing the hyoid bone invariably showed a positive relationship with F0.
(4) This thin flap, usually extending from the hyoid bone to the sternal notch at the central part of the anterior neck, provides a skin island of about 4 by 8 cm.
(5) Therefore, 90 patients with documented obstructive sleep apnea were evaluated by cephalometric technique, with special attention paid to the size and position of the soft palate and uvula, volume and position of the tongue, mandibulo-maxillary relationship, hyoid position, and size of the pharyngeal airway space.
(6) The vital composite hyoid bone-muscle graft interposition technique offers a promising method for the solution of difficult cases of glottic, subglottic, and tracheal stenosis.
(7) After cephalometric analysis, poor responders were revealed to show significantly poor mandibular prognatism and also lower positioned hyoid bone than good responders.
