The correlation of biomechanical events of deglutition has been described in the literature and its characteristics associated with electromyography establish the suprahyoid
musculature as that which reflects the verification of this functional event.
They analysed the EMG potentials of the anterior temporalis, masseter, and suprahyoid
muscles at rest position and during MVC on parafilm.
As the vertical dimension is increased with an intra oral appliance, as an example, the mandible will be displaced downward which in turn releases suprahyoid
Although neck tenderness is commonly observed, it is not a reliable sign of impaction.2 Within the regions of the upper aerodigestive tract, palatine tonsil, posterior tongue and vallecula are common sites of suprahyoid
impaction and piriform fossa, larynx, cricopharyngeus, cervical oesophagus and thoracic oesophagus are less common sites of infrahyoid impaction.3
The spaces of the suprahyoid
neck were originally described by anatomists and surgeons in the 19th century as they dissected the layers of the deep cervical fascia, attempting to better understand the extension of infections of the extracranial head and neck to other areas in the neck, chest, and abdomen.
(11) as follows: stage/class I, infrahyoid unilateral lesions; stage/class II, suprahyoid
bilateral lesions; stage/class III, suprahyoid
or infrahyoid unilateral lesions; stage/class IV, suprahyoid
bilateral lesions; stage/class V, suprahyoid
or infrahyoid bilateral lesions; and stage/class IV, infrahyoid bilateral lesions.
Prolonged, untreated dysphonia results in problems with the neuromuscular apparatus of the larynx, increased tension of masseter, buccal fundus, and suprahyoid
muscles, which excessively raises the position of the larynx [12,13].
The Shaker exercise is a series of sustained and repetitive head lifting exercises to enhance the strength of infrahyoid and suprahyoid
muscular activity [1, 2].
The neck ultrasound revealed a pattern suggestive of a thyroglossal duct cyst: a single, midline, suprahyoid
cyst containing debris and an eccentric small hyperechoic solid area.
Kiliaridis and Katsaros  say that the increasing of the vertical growth is due to an alteration of the perioral muscles in combination with a minor involvement of suprahyoid

cervicofacial lymphangioma with intravenous cyclophosphamide," American Journal of Pediatric Hematology/Oncology, vol.
muscles are dissected from the hyoid bone .
